Hello, 

 

I am working on tizen native application. http post method was working before the installation of tizen studio 2.0 

 

Now i have installed tizen studio 2.0 so now my http post method is not working properly.

Though i have given correct parameters, am not getting the expected results.

Tizen Studio 2.0 Release Notes don't contain any notice regerding http POST request.

https://developer.tizen.org/development/tizen-studio/download/release-notes

 

An IDE update won't make changes in API. What was the target device on your test environment before? Was it the same Mobile-3.0x86 emulator? Or any other version of Emulator or a real device? I would suggest to try with a different emulator or device first.

I'm sharing sample code for HTTP POST request. Hope It helps.

 

int ret = HTTP_ERROR_NONE;
char uri[1024] = "http://posttestserver.com/post.php";
const char* post_msg = "name=tizen&project=http";

ret = http_session_create(HTTP_SESSION_MODE_NORMAL, &session);
if (ret != HTTP_ERROR_NONE)
  dlog_print(DLOG_DEBUG, "my_tag","http_session_create failed: %d", ret);

//Transaction for HTTP POST:
ret = http_session_open_transaction(session, HTTP_METHOD_POST, &transaction);
if (ret != HTTP_ERROR_NONE)
   dlog_print(DLOG_DEBUG, "my_tag","http_session_open_transaction failed: %d", ret);

ret = http_transaction_request_set_uri(transaction, uri);
if (ret != HTTP_ERROR_NONE)
   dlog_print(DLOG_DEBUG, "my_tag","http_transaction_request_set_uri failed: %d", ret);

//Data management for HTTP POST:
http_transaction_set_ready_to_write(transaction, TRUE);
http_transaction_request_write_body(transaction, post_msg);

ret = http_transaction_submit(transaction);
if (ret != HTTP_ERROR_NONE)
    dlog_print(DLOG_DEBUG, "my_tag","http_transaction_submit failed: %d", ret);

header_cb(http_transaction_h http_transaction, char *header, size_t header_len, void *user_data){
    // response received header here (char *header)
}

body_cb(http_transaction_h http_transaction, char *body, size_t size, size_t count, void *user_data){
    // response received body here (char *body)
}

// Registers callback called when receives header. 
http_transaction_set_received_header_cb (transaction, header_cb, null);
http_transaction_set_received_body_cb (transaction,body_cb, null);

Armaan-Ul- Islam actually we have the same code but mine is not working. i have a question do i have to change the format of post_msg to JSON format?

 

const char* post_msg = "name=tizen&project=http";

hi i have a follow up question. my goal is to get the value "userId: 1" "id:2" what will be the format of post_msg? thanks


[
  {
    "userId": 1,
    "id": 1,
    "title": "sunt aut facere repellat provident occaecati excepturi optio reprehenderit",
    "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto"
  },
  {
    "userId": 1,
    "id": 2,
    "title": "qui est esse",
    "body": "est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla"
  },

As far as I've understood, Your post message should be like:

const char* post_msg = "userId=1&id=2";

It's pretty common that Servers send HTTP response in JSON format, but Servers receiving HTTP Request in JSON format seems not that commonly followed standard.

According to the post, You might give this a try:

const char* post_msg = "data={\"userId\":\"1\",\"id\":\"2\"}";
