Hi,

I am trying the "http_post " on tm4c1294ncpdt, using CCS V6.2, TI-RTOS V2.16.

It was sending the fields and the body successfully, but after the sent waiting for getting the response code so getting timeout, Error! code = 408.

Please find the attach for the code.0434.httpPost_EK_TM4C1294XL_TI.rar

Console Print:

================================================================

s in flash
Starting the HTTP POST example
System provider is set to SysMin. Halt the target to view any SysMin contents in ROV.

Sending a HTTP POST request to 'www.example.com'
sendRequest successful
sendField type successful, ret=0
send field length successful, ret=0
Request body sent successfully ret=0
Error! code = 408, desc = httpTask: cannot get status

================================================================

I was tried for different return types also but no use.

Hi,
"httpget.c" is the main and task is calling inside the "netIPAddrHook()". Going to wait on calling "HTTPCli_getResponseStatus()" .

Hi Raghu,

There are a few issues with your example code. I have modified and attached the fixed code. Please take a look.

In general, you don't need to prefix the header type to the header value i..e from your example:

char *CONTENT_TYPE = "Content-Type: application/json"; // this is not correct

char *CONTENT_TYPE = "application/json"; //this is correct

And, make sure the last param is set to true for the last HTTPCli_sendField() call in your example. This would ensure the header endings are sent to the server otherwise the server would not be able to differentiate between the header and the body, and would send back an error HTTP status code.6661.httpget.c

Hi Vikram,

Thanks for the reply and support. The problem is solved now and I can post to server.

I am trying for the "HttpsPost" in the same way and getting response code "504", the Gateway timeout.

Please find the attach for the project.

There is a mismatch between the content length and the actual number of the bytes sent in the body in your application. Since content length is 18, the server is waiting for 18 bytes to arrive from the client where as your application is just sending 16 bytes of content. Hence the wait timeout and 504 error code.

Please mark this thread as answered if it is answers your question.
