I am new to golang, want to modify shadowsocks-go code to parse https raw response bytes to check whether the google, facebook or twitter has blocked our service or not. Shadowsocks-go uses socket5 to read https data, I checked golang http module, still don't know how to parse https raw bytes. From google, examples are only about how to use go http module.
Update
Actually, I want to make a Reverse Proxy, every proxy node contains a shadowsocks server. So every request I want to know the destinations whether block our request or not, if blocked, need to remove the node, and add new one. This requirement need to parse the https raw bytes to check response status.
You can make secure requests via go's net/http library. Just use the https:// scheme in the URL.

I am trying to get an access token via RestTemplate.postForEntity().
myRestTemplate.postForEntity(authBaseUrl, request, Object.class);
I have a specific class for it, but let's use now a simple Object as type. It contains an access_token field.
It works, because I can get response, but the length if the access tokens (which is a string)
is 1196 character long. And I can get the same length in Postman too.
But if I use the intelliJ built-in REST client, the length is 1199.
Only the token from the intelliJ rest client works (So the longer).
Because I always get a new access token, it is impossible to get the same token twice.
How can I debug it?
What could be the problem?
Is the code that generates the response available to you? if so in your response add a header content-length so you can see what the server sent and what you received. Also, debug the server side and see what is being generated. In addition take another 3d party Http client and test it with this client see if you see a difference. The Http clients that you can try are Apache Http client, OK Http client, or my favorite - a very simplistic client written by me as part of my own Open Source MgntUtils library. Here is the Javadoc for my http client Here is a link to a similar question where you can get the references for any of above mentioned Http clients: How to check the status of POST endpoint/url in java
I am trying to connect to an API that uses websockets. I need to do the following:
Connect to the websocket using a given URI
Send a login request
Send a request for the required data stream(s)
Store the returned streamed data in an array for immediate processing (the array will be continually updated while data is streamed)
When finished collecting data, send a logout request
I have a general understanding of websockets, but have never tried to connect to a websocket. I have read through the “documentation” for packages HTTP (which I have used before), WebSockets, and DandelionWebSockets. Each has left me scratching my head trying to understand how to implement the above tasks.
Would someone please help by showing me, line-by-line, how to set up the above tasks and also explain why each line or function is used? (Assume I have the correct URI, login, data, and logout request formats.)
I want to send SMS from AngularJS web application using Ozeki sms gateway. Can anyone tell me how to do this? pr suggest me some reference link or code sample.
Plain sending
Assume we skipping other protocols available inside Ozeki Sms NG product (like SMPP, Email, DB etc), and getting to HTTP protocol only, you can go this way:
Prerequisites:
Figure out best way for you to make HTTP request to send SMS
(I'm not AngJS guy so may be there are already few ways to make HTTP-request from Angular, but at least any Ajax method passing params to executing PHP-script for making HTTP request (with curl, file_get_contents) will be totally Ok).
Make sure your Ozeki SMS server is reacheable via IP/domainname etc by your PHP-script so your code can reach its endpoint.
Doing it:
Inside Ozeki install service provider like HTTP Client
http://www.ozekisms.com/index.php?owpn=195&info=service-provider-connections/http-client-connection
or HTTP Server (more powerful version of HTTP Client allowing call back URLs)
http://www.ozekisms.com/index.php?owpn=197&info=service-provider-connections/http-server-connection
Then according (to docs) execute request like
http://server_ip:9501/api?action=sendmessage&username=________&password=________&originatior=__________________&recipient=__________________&messagetype=SMS:TEXT&messagedata=______________
*Some fields are not necessary, it may vary depending on Ozeki version you use.
** port 9501 - is a default Ozeki HTTP port which may be changed in general settings, also it has HTTPS port as well. Basically the correct port is the same which you already use when accessing Ozeki Web GUI.
After executing sending request (try from browser or from something like Postman first) you should get responce in XML format informing you about result of your transaction.
Possible next step... DLRs
Getting delivery reports (if supported by your operator) is a common "i want it too" question.
In case you need them - there is great embedded feature inside "HTTP Server" connector (mentioned above).
Here you can see more details
http://www.ozekisms.com/index.php?owpn=431
"reporturl" - is a field you may use to set kind of "call back url". In other words in this optional field you may specify full URL and list fields to be passed along. So you only have to create your own endpoint to catch them (as GET request from Ozeki server) and use inside your software.
I am trying to send binary data from my AWS Lambda function as a response to an AWS Gateway GET Method that DOES NOT use Lambda Proxy integration. I have tried all sorts of variations but still can't make it work, although I feel like I am close.
My API Gateway HTTP request is returning:
But what I want is is the actual binary data:
I did attempt using a mapping template, but was unsuccessful due to my lack of understanding the templating syntax/behavior(I tried $util.base64Decode($input.body) but that produced a server error).
But I wasn't sure if that was even necessary since I have the content handling set to Convert to binary.
I ran into this problem but I used a proxy url. Make sure to enable Binary Media Types. Also do not forget to deploy your changes, simply saving is not enough. Also make sure you have the correct content type in the header with client sending the payload.
I've got a (Spring) handler that I'd like users to be able to bookmark. As it's coded now, they get different formats (CSV, JSON) back based on the Accept header.
Would there be any way for users to specify the URL so that they can say what header they want? Or am I going to have to give URL-level parameter for the different formats?
Would there be any way for users to specify the URL so that they can say what header they want?
no there is no way to do that magically.
Or am I going to have to give URL-level parameter for the different formats? Yes this is valid
This is quoted from xml.com:
Server-driven negotiation. The service provider determines the right representation from prior knowledge of its clients or uses the information provided in HTTP headers like Accept, Accept-Charset, Accept-Encoding, Accept-Language, and User-Agent. The drawback of this approach is that the server may not have the best knowledge about what a client really wants.
Client-driven negotiation. A client initiates a request to a server. The server returns a list of available of representations. The client then selects the representation it wants and sends a second request to the server. The drawback is that a client needs to send two requests.
Proxy-driven negotiation. A client initiates a request to a server through a proxy. The proxy passes the request to the server and obtains a list of representations. The proxy selects one representation according to preferences set by the client and returns the representation back to the client.
URI-specified representation. A client specifies the representation it wants in the URI query string.
