Question:

Http POST become GET when Content Type is text/namevalue

Jun 24 '15 at 20:34

Hi Chilkat,

I tried to send a Http POST (without url encoding for the params), but when I looked at the log, the request become a GET instead !

As I understood from the following link, content-type should be set to "text/namevalue".

http://www.example-code.com/vcpp/paypal_creditcardpayment.asp

I tried both

a. Request.put_ContentType("text/namevalue");

b. Request.AddHeader("Content-Type","text/namevalue");

still it doesn't work ie. GET is sent instead of POST.

Latest library is used ie.v9.5.0.50 VC++ 9.0 / win32 (VS2008).

I believe it is a bug.

Fya.

Best regards

Dragon

Check out the documentation of the RedirectVerb property (I think it will help):

RedirectVerb Indicates the HTTP verb, such as GET, POST, PUT, etc. to be used for a redirect when the FollowRedirects property is set to 1. The default value of this property is "GET". This will produce the same behavior as a web browser (such as FireFox). If this property is set to the empty string, then it will cause the same verb as the original HTTP request to be used.

Note: Prior to version 9.5.0.44, the default value of this property was the empty string.

If you explicitly clear the RedirectVerb property, do you get a POST after redirect?

Hi jpbro,

Sorry for my late reply and thanks again for your fast response !

I looked at the log again. My mistake ! I missed out the detail.

Initially, a Correct POST was sent. However, the response received is :

HTTP/1.1 302 Moved Temporarily

Then, the problem appeared, the POST was resend....

It become a GET....

Hence, need to test on a website which will reply "HTTP/1.1 302 Moved Temporarily" to see the issue.

Thanks.

Did you call UsePost on the CkHttpRequest object (though deprecated, I believe it still works), or event better set the HttpVerb property of the CkHttpRequest object to "POST"?

Answer

Hi jbro,

Thanks for your fast reply.

Yes, I did.

Request.put_HttpVerb("POST");

Request.put_Path("/login.php");

Request.put_ContentType("text/namevalue");

Request.AddHeader("Accept","application/json, text/javascript, /; q=0.01");

Request.AddHeader("X-Requested-With","XMLHttpRequest");

Request.AddHeader("Accept-Language","zh-CN");

Request.AddHeader("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; rv:11.0) like Gecko");

Request.AddHeader("Connection","Keep-Alive");

Request.AddHeader("Host",szDomain);

Request.AddHeader("Pragma","no-cache");

Request.AddParam("act","login");

Request.AddParam("tbUserAccount",szUserAccount);

Request.AddParam("tbUserPwd",szUserPwd);

Request.AddParam("tbCode","");
