How to add header parameters in HTTP GET and POST Request

Other Parts Discussed in Thread: EK-TM4C1294XL

Hi,

We have to send some parameters as part of the header in HTTP request which is being send to Server. I have seen enet_weather and enet_io examples and checked most of tcp methods but did not find any struct which accepts HTTP header.

We have to send Authorization, Context-type, Accept-Encoding etc in Request Header which is being sent to Server. Also have to add parameters when someone opens web page (as in enet_io) also want to restrict access based on parameters. 

Can anyone guide me to solve this? 

I am using EK-TM4C1294XL board with CCS  Version: 6.1.0.00104 and TivaWare_C_Series-2.1.1.71 on Windows 8.

Thanks,
Bhavesh

    Hello Bhavesh

    Did you check lwIP for details on adding parameters?

    Hi Amit,

    In LwIP there is a single parameter LWIP_HTTPD_DYNAMIC_HEADERS which is used for headers when Web Page is opened from Hub.
    While sending data to server as we are directly using tcp/ip methods, there is no explicit header flag, and it should be copied in pcRequest directly followed by \r\n. Following is the generated string as below:

    "GET api.openweathermap.org/.../weather HTTP/1.1\r\n Authorization: basic\r\n Accept-Encoding: gzip, deflate, sdch \r\n\r\n"

    This can be used for any REST APIs. This is working fine.
    When Hub acting as a server LWIP_HTTPD_DYNAMIC_HEADERS will be used to carry out header part. Still working on this part and will update if everything works out.

    Thanks,
    Bhavesh
