ColdFusion Proxy Server - proxy

I'm trying to create a basic proxy server so I can keep track of what my kids are doing web wise - I know there are products out there but I thought it would be an interesting exercise to write one myself.
I have the following code that kind of works but doesn't pull any images or css through - I guess because it makes another call to the remote server and gets confused
<cfhttp url="https://www.bbc.co.uk">
<cfhttpparam type="header" name="Proxy-Connection" value="keep-alive" >
<cfhttpparam type="header" name="Accept" value="application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5">
<cfhttpparam type="header" name="Accept-Language" value="en-US,en;q=0.8">
<cfhttpparam type="header" name="Accept-Charset" value="ISO-8859-1,utf-8;q=0.7,*;q=0.3">
</cfhttp>
<cfset html = cfhttp.FileContent />
<cfoutput>#html#</cfoutput>`
What am I missing?

What you want to use is the resolveurl parameter of - set it to yes/true. This defaults to no.
What this parameter does is resolves relative paths to absolute paths automatically for you.
Now, if you want to change those paths as well, you would change them to also route through your http proxy script, but there won't be much use as you won't know much about the content regardless.
resolveurl should hook you up with what you are looking for. cheers.

Cypress-Xpath: Correct Xpath syntax for id? It can't find it

Tried cy.get(#Username) , doesn't work- cypress says it can't find it. could it be related to uppercase letter?
Installed Xpath plugin and used this
cy.xpath('//input[#id="Username"]') but it didn't work.
<input type="email" class="form-control" autocomplete="off" data-gd="identity-login-local-form-username" autofocus="" data-val="true" data-val-required="The Username field is required." id="Username" name="Username" value="">
Please before giving -1 , please explain what I need to improve. Thanks!
After downloading xpath plugin, did you add require('cypress-xpath') in your project's cypress/support/index.js file?
According to your example, code below should find the Username
cy.xpath('//input[#id="Username"]')
cy.get('#Username')
The capital letter may be causing the problem. Usually ids have a small letter.
Try using the data-gd attribute instead.
cy.get('[data-gy="identity-login-local-form-username"]')
If that does not work, you may have some shadow DOM before the <input> that blocks the search, in which case you can search inside the shadow like this
it('tests the input', {includeShadowDom:true}, () => {
cy.get('[data-gy="identity-login-local-form-username"]')
})
I tested with a capital letter cy.get('#Username') and cy.xpath('//input[#id="Username"]') - both worked for me, so likely there is shadow DOM or an <iframe> on your page.
Is it possible that the page has a default namespace? If the page is served as XHTML, it may have a default XML namespace, in which case the input's name is not simply input.
If that is the problem, then you could declare the http://www.w3.org/1999/xhtml namespace and associate it with a prefix, e.g. xhtml (I don't know cypress so not sure how you'd do that), and then query for //xhtml:input[#id="Username"]. An alternative is to query for an element whose local name is input in any namespace at all, e.g. //*[local-name()='input'][#id="Username"]
In case your username field is under a shadow DOM which means other fields will also be under the shadow Dom, it would be advisable to write includeShadowDom: true in your cypress config file to avoid repetition(cypress.json if cypress version < 10; cypress.config.js if cypress version > 10), then directly use the command:
cy.get('#Username').type('username-text')
In case your username field is under an iframe, you can get the cypress iframe plugin
To install npm install -D cypress-iframe
Go to cypress/support/commands.js file, add the following:
import 'cypress-iframe';
// or
require('cypress-iframe');
In your test write:
cy.iframe('#my-frame')
.find('#Username')
.should('be.visible')
.type('username-text')
I can also confirm the way you are selecting the Username input element is correct.
If you suspect shadow DOM is interfering with your test, the best way to debug IMO is to
inspect your DOM around the <input>
look for a parent element that has #shadow-root below it (in bold)
change the test to include this parent
add the .shadow() command after the parent to break through the barrier
cy.get('parent-with-shadow-root')
.shadow()
.find('#Username')
This debugs and confirms your issue. Everything else, e.g setting global config etc can be done after you know what you have to deal with.
After I tried suggestions and people's confirmation that my xpath was correct, I shifted my focus on the error I got while Cypress was trying to find the element. The error I got was uncaught exception.https://stackoverflow.com/questions/53845493/cypress-uncaught-assertion-error-despite-cy-onuncaughtexception
This error occurs when a module fails to load due to some exception. The error message above should provide additional context. A common reason why the module fails to load is that you've forgotten to include the file with the defined module or that the file couldn't be loaded.
Using ngRoute In AngularJS 1.2.0 and later, ngRoute has been moved to its own module. If you are getting this error after upgrading to 1.2.x or later, be sure that you've installed ngRoute.

How to show error log in a template in eXist-db, not outside of it?

In the controller I have:
else if (ends-with($exist:resource, ".html")) then
(: the html page is run through view.xql to expand templates :)
<dispatch xmlns="http://exist.sourceforge.net/NS/exist">
<view>
<forward url="{$exist:controller}/modules/view.xql">
<set-header name="Cache-Control" value="no-cache"/>
</forward>
</view>
<error-handler>
<forward url="{$exist:controller}/error-page.html" method="get"/>
<forward url="{$exist:controller}/modules/view.xql"/>
</error-handler>
</dispatch>
Typically, this helps when a templating function fails (like <div class="app:list-journals"/>). How to use that for any function failing on the background (e.g. after submission of a form)?
UPDATE
Here is the code where I am trying to catch the error of the templating function:
...
} catch * {
<error>Error {$err:code}: {$err:description}</error>
}
This does not work. The app still uses its own logs as bare XML responses.
Or I would expect this:
...
} catch * {
logger:add-log-message(concat('Error: ', $err:code, $err:description))
}
... could work with some redirecting to a global error page but it does not. As soon as the error is not the problem of the app but, let's say, of a XSLT process, it is not possible to redirect the app to some global page as described in the book by A. Retter (it is necessary to use $EXIST_HOME/webapp/WEB-INF/web.xml file and there to describe the error and the particular page for redirecting).
More information, no progress.
Well, this question is rather clumsy and the answer has to be a bit cumbersome. The problem is I was not aware of several things regarding to errors and their relationship with XQuery and eXist’s templating module.
It seems there are basically three levels of errors I can deal with on the surface:
1 — errors associated with templating
These errors are the easiest to solve. It is enough to define an error handler in your controller for URL rewriting (in general or for a particular page):
else if (ends-with($exist:resource, ".html")) then
<dispatch xmlns="http://exist.sourceforge.net/NS/exist">
<view>
<forward url="{$exist:controller}/modules/view.xql">
<set-header name="Cache-Control" value="no-cache"/>
</forward>
</view>
<error-handler>
<forward url="{$exist:controller}/error-page.html" method="get"/>
<forward url="{$exist:controller}/modules/view.xql"/>
</error-handler>
</dispatch>
If any function associated with templating fails, the log is showed inside a frame and it looks like a common part of your app page:
2 — errors associated with some special HTTP code via Jetty
These errors are logged by Jetty—the page disappears and instead of it there is usually a long log. It is possible to make a record of such an error in the $EXIST_HOME/webapp/WEB-INF/web.xml:
<error-page>
<error-code>404</error-code>
<location>/db/central/page404.xq</location>
</error-page>
The location should, logically, point to a real page inside of your app. And we can’t forget to its definition in our controller.xql:
else if ($exist:path eq 'error-404.html') then
<dispatch xmlns="http://exist.sourceforge.net/NS/exist">
<forward url="{$exist:controller}/errors/error-404.html"/>
<view>
<forward url="{$exist:controller}/modules/view.xql">
<set-header name="Cache-Control" value="no-cache"/>
</forward>
</view>
</dispatch>
This solution is useful if you know about repeating errors you want to make more friendly to users. Great for HTTP 404 or HTTP 500 errors. HTTP 500 errors are the biggest problem because the are associated with errors made by functions running. Nice solution.
3 — the rest
In XQuery, there are several types of errors. For dynamic errors (thrown during runtime and logged as HTTP 500 errors by Jetty) it is possible to use try/catch statements. With them, it’s possible to catch logs and to store them somewhere in your app. If you treat them like me in the number 2, it is enough. Other types of errors are (from my point of view) much harder to catch (static, typed and so on). This means there is no easy way how to hide them for users. The plus is you usually know about them earlier during prototyping and testing, anyway.
Maybe there is some complex possibility of showing all errors in a friendly way but it is outside of space and time of this forum. Inspiration is in Demo apps. Such a solution may be a bit time consuming and it’s a bit artificial problem at the moment.
Any clarifications and arguments are very appreciated.

Oracle Service Bus - Assign expression

I have this problem and I am not sure why it's happening and how to fix it. I have created an OSB peject. In the proxy service pipeline I am doing a Service Callout to a sync SOAP service in another application. The other service needs the request body as below:
<RequestSelectionValues xmlns="http://www.camstar.com/WebService/WSShopFloor">
<inputServiceData xmlns:q1="http://www.camstar.com/WebService/DataTypes" q1:type="OnlineQuery">
<OnlineQuerySetup>
<__CDOTypeName/>
<__name>xLot By FabLotNumber</__name>
</OnlineQuerySetup>
<Parameters>
<__listItem>
<Name>FabLotNumber</Name>
<DefaultValue>FAB_Lot_1</DefaultValue>
</__listItem>
<__listItem>
<Name>BLOCKOF200ROWS</Name>
<DefaultValue>1</DefaultValue>
</__listItem>
</Parameters>
</inputServiceData>
<queryOption xmlns:q2="http://www.camstar.com/WebService/DataTypes" q2:type="QueryOption">
<RowSetSize>1000</RowSetSize>
<StartRow>1</StartRow>
<QueryType>user</QueryType>
<ChangeCount>0</ChangeCount>
<RequestRecordCount>false</RequestRecordCount>
<RequestRecordSetAndCount>false</RequestRecordSetAndCount>
</queryOption>
<serviceInfo xmlns:q3="http://www.camstar.com/WebService/DataTypes" q3:type="OnlineQuery_Info">
<OnlineQuerySelection>
<RequestValue>false</RequestValue>
<RequestMetadata>false</RequestMetadata>
<RequestSubFieldValues>false</RequestSubFieldValues>
<RequestSelectionValues>true</RequestSelectionValues>
</OnlineQuerySelection>
</serviceInfo>
</RequestSelectionValues>
I am using an Assign to put the above expression in a variable.
Notice the line:
<serviceInfo xmlns:q3="http://www.camstar.com/WebService/DataTypes" q3:type="OnlineQuery_Info">
xmlns:q3="http://www.camstar.com/WebService/DataTypes" needs to be before q3:type="OnlineQuery_Info" for the other service to be called successfully otherwise the service call fails.
In the development it looks fine. I can test the assign of expression as well.
When I go to the OSB console to test the service I notice that in the Assign variable the namespace place switches and it becomes like this:
<serviceInfo q3:type="OnlineQuery_Info" xmlns:q3="http://www.camstar.com/WebService/DataTypes">
This makes the service calls to fail. I have tried putting the body payload in an xslt. Result is the same. I am not sure why it switches the type before namespace. The end result is that the service is not working as expected.
Any idea what I can do to fix this issue. How can I prevent the switching?
Thanks
I haven't found any settings in OSB that can prevent reordering of attributes for you. However, the above OSB behavior is completely XML standard compliant. In fact, the target service side should be XML compliant and treat the two variants mentioned above as the same, because according to XML standard, tow XML documents with only difference in attribute ordering should be treated as the same.
EDIT:
Please go here to download a modified config. My thoughts are:
Specify the business service to invoke in 'Text as Request' mode, as "CamstarLotQuery/business/CSWSShopFloor_Txt" shown below:
Manipulate messages as text, not XML, in your proxy service, as specified in "CamstarLotQuery/proxy/CamstarLotQueryTxt_Txt":
You might need to specify a SOAP Action in http header when calling a business service, depending on the target service.
One solution i can think of is to assign all the namespaces at the Parent Tag Level, and keep the attributes where they are applicable.
Example:
<RequestSelectionValues xmlns:q1="http://www.camstar.com/WebService/DataTypes" xmlns="http://www.camstar.com/WebService/WSShopFloor" xmlns:q2="http://www.camstar.com/WebService/DataTypes" xmlns:q3="http://www.camstar.com/WebService/DataTypes">
But the problem with this implementation is that since the namespace declaration is now Global, you have to declare your namespace prefixes (q1, q2, q3) to the blocks where the namespaces were previously defined.
Example:
<q3:serviceInfo q3:type="OnlineQuery_Info">
<q3:OnlineQuerySelection>
<q3:RequestValue>false</q3:RequestValue>
<q3:RequestMetadata>false</q3:RequestMetadata>
<q3:RequestSubFieldValues>false</q3:RequestSubFieldValues>
<q3:RequestSelectionValues>true</q3:RequestSelectionValues>
</q3:OnlineQuerySelection>
</q3:serviceInfo>
if this namespace prefix is not declared, then as per XML standards, the tag assume the 'default' namespace value - which will be the namespace of the parent.
However, even though this solution has a round-about way of implementation, this solution will definitely work.

ImageScaleToFit - how to implement?

I'm new to Railo, moving away from ColdFusion 8 where my site used to used to use cfx_imagecr3.
I believe Railo has ImageScaleToFit but I'm not sure if I'm using it correctly or if I need to add some kind of class/component? I've added it between a cfscript but i get 'invalid variable declaration' which doest make any sense to me. Any help appreciated.
I'm running railo-4.0.0.013 on ubuntu 12.04
<cfscript>
imageScaletoFit('/home/images/testimage.jpg','90','114','highestPerformance');
</cfscript>
You need to first load the image into a variable, then use that variable name inside ImageScaletoFit, like so:
<cfimage name="ImgVariable" source="/home/images/testimage.jpg" />
<cfset imageScaletoFit(ImgVariable,'90','114','highestPerformance') />
(This isn't specific to Railo - the function exists and works the same way in CF8+)

ClientGlobalContext.js.aspx broken in Dynamics 2011?

I am trying to implement a custom web resource using jquery/ajax and odata. I ran into trouble and eventually found that when I call:
var serverUrl = context.getServerUrl();
The code throws exceptions.
However, when I change serverUrl to the literal url, it works. I then found forum posts that said I should verify my .aspx page manually by going to https://[org url]//WebResources/ClientGlobalContext.js.aspx to verify that it is working. When I did that I received a warning page:
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
--------------------------------------------------------------------------------
Invalid at the top level of the document. Error processing resource 'https://[org url]//WebResources/Clien...
document.write('<script type="text/javascript" src="'+'\x26\x2347\x3b_common\x26\x2347\x3bglobal.ashx\x26\x2363\x3bver\x2...
What the heck does that mean?
Hard to tell outside of context (pun not intended) of your code, but why aren't you doing this?
var serverUrl = Xrm.Page.context.getServerUrl();
(Presumably, because you have defined your own context var?)
Also, this method is deprecated as of Rollup 12, see here: http://msdn.microsoft.com/en-us/library/d7d0b052-abca-4f81-9b86-0b9dc5e62a66. You can now use getClientUrl instead.
I now it is late but hope this will be useful for other people who will face this problem.
Until nowadays even with R15 there are two available ClientGlobalContext.js.aspx
https://[org url]/WebResources/ClientGlobalContext.js.aspx (the bad one)
https://[org url]/[organization name]/[publication id]/WebResources/ClientGlobalContext.js.aspx (The good one)
I don't know why exist 1. but it causes many issues like:
It could not be published or hold information (Your case #Steve).
In a deployment with multiple organizations, seems it saves info only for the last organization deployed causing that methods under Xrm.Page.context. will return info from a fixed organization. Actually each method that underground uses these constants included in ClientGlobalContext.js.aspx: USER_GUID, ORG_LANGUAGE_CODE, ORG_UNIQUE_NAME, SERVER_URL, USER_LANGUAGE_CODE, USER_ROLES, CRM2007_WEBSERVICE_NS, CRM2007_CORETYPES_NS, AUTHENTICATION_TYPE, CURRENT_THEME_TYPE, CURRENT_WEB_THEME, IS_OUTLOOK_CLIENT, IS_OUTLOOK_LAPTOP_CLIENT, IS_OUTLOOK_14_CLIENT, IS_ONLINE, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_SERVER_HOST, WEB_SERVER_PORT, IS_PATHBASEDURLS, LOCID_UNRECOGNIZE_DOTC, EDIT_PRELOAD, WEB_RESOURCE_ORG_VERSION_NUMBER, YAMMER_IS_INSTALLED, YAMMER_IS_CONFIGURED_FOR_ORG, YAMMER_APP_ID, YAMMER_NETWORK_NAME, YAMMER_GROUP_ID, YAMMER_TOKEN_EXPIRED, YAMMER_IS_CONFIGURED_FOR_USER, YAMMER_HAS_CONFIGURE_PRIVILEGE, YAMMER_POST_METHOD. For instance method Xrm.Page.context.getUserId() is implemented as return window.USER_GUID;
