I'm trying to make some automatic captcha input systems (recognition of figures in captcha image by deep learning and input the figure automatically)
.
For that, the captcha image should be inputted to some deep learning system.
The captcha image in some online web page is in the img src but the src is not ending with some file extension like jpg, png..
It look like the below(it is an example).
img src="/nn/mm/captchaimg?/kk=image"
The above image shown in the web browser is changing after some time periods(about 1,2 min).
If the web including the above image is reloaded, the captcha is changed to another captcha image
(It means that in web crawler, the image is changed to by each request to server).
How to save the above image which has the above special properties in html in crawler?
I'm now doing it with goquery in Golang.
I should do
Saving the captcha image in the web page got by requesting in crawler.
Getting the figures in the above captcha image using my deep learning system.
Input the figures to the form in the above web page in step 1(with maintaining the session, reload or retry of requesting should not be done) and submit
I have done deep learning system in Step 2(test be done, it works well).
But I have no idea of Step 1, 3.
Any advice will be helpful to me.
Thank you in advance.
There are lots of documents about downloading the image in golang crawlier.
But I cannot find the methods to download the images changing by requesting the image URL
(I want to download the first image when I request the web page including the image at first time).
I've added Roxy Fileman to my project and tied it in to CKEditor. It's a standard Durandal project with an MVC controller for routing and a web api controller for ajax/json data calls.
A typical working URL for a web api call in my app is http://localhost:63093/api/DurandalApi/getAssessmentQuestionnairePushMenu?id=1
When I try and upload a file from within CKEditor, I get:
Request URL:http://localhost:63093/fileman/index.html?type=image&CKEditor=ckeditor&CKEditorFuncNum=1&langCode=en
Request Method:POST
Status Code:405 Method Not Allowed
Remote Address:[::1]:63093
If, however, I directly go to http://localhost:63093/fileman/index.html?type=image&CKEditor=ckeditor&CKEditorFuncNum=1&langCode=en in my browser, the file upload works perfectly and I can then browse to the image from FileMan inside CKEditor.
The network tab in chrome dev tools indicates that the successful upload is done using this URL: http://localhost:63093/fileman/asp_net/main.ashx?a=UPLOAD which is significantly different to the one that CKEditor attampts to use, but that may be because in the second example, index.html is already loaded?
I'm not completely up to speed with what's going on, but the fact that the same URL works perfectly outside of Durandal if I go directly to the URL seems to indicate the FileMan plugin is working just fine and all permissions are set accordingly. Furthermore the CKEditor config is also fine as it can see the images I upload in the directory, but for some reason it's unable to "post" from within CKEditor (which is embedded in a standard Durandal view).
I'm trying to read up on routing to see if I need to do some kind of exception mapping in Durandal to tell it to let the 3rd party .ashx handler deal with the POST request and I'm not even sure if this problem is indicative of Durandal getting in the way or something else. Any suggestions gratefully received!
Ah. All has become clear. This is a half and half answer really as it doesn't really solve the problem, but equally the problem doesn't really exist!
The issue is that Roxy Fileman does NOT use the CK Editor inbuilt "upload" tab that is in the popup. It expects the user to "browse server" only and use the "add file" link in Roxy instead.
I was confused by the instructions, but now I understand!
I have 2 controls on SharePoint page one is yammer embed feed and 1 content editor webpart with REST API call.
When I refresh page multiple times with some duration then it is throwing error as "yam.request is undefined". Please note I am using platform_js_sdk.js for REST API.
#Yammer team: can you please try and check issue with platform_js_sdk.js file?
Generally, having two yammer feeds on the same page doesn't work well, whether it be with embed or the rest api. One workaround is to use a page viewer web part which hosts the individual pieces of functionality.
I have a QR code image that's embedded from the Google Charts API. Recently it stopped working, but I haven't changed anything in my code.
Here's the page (note the broken images): [redacted]
As you can see, the images are embedded as http:// but when they are loaded, they're redirecting to the https:// URL on the google domain, which is broken.
Why is this redirect happening?
Edit: forgot to add -- what's even stranger is that if you view the image in a new tab, then change http to https (in effect, making the url the exact one that was originally requested),
it loads fine.
Edit #2 removed the link to my test site, as I've fixed the problem.
Turns out the google charts domain has changed. The new one is:
https://chart.googleapis.com
do not use
http://chart.apis.google.com
I am looking at the Gawker blogs (http://io9.com, http://lifehacker.com/) and I'm curious about how they are made.
When I click for on a link only the article part of the page reloads displaying a loading icon while it does.
But what I can't figure out is that links point to new URLs like io9.com/something/something and its not something like I see on ajax pages that they put a site.com/#something tag at the end of the url from javascript to mark the page after an ajax request.
Can I change the full blown URL from javascript or what is happening?
When it happens, the website is using the HTML5 History API. This API can change the url (via JavaScript) without changing the page.
See caniuse.com for browser support.
If you would like to implement it in yout website, backbonejs.org would be very useful.
