Detailed Description

HTTP/1.1 Client interface.

This module provides a HTTP client implementation of IETF standard for HTTP/1.1 - RFC 2616 and TLS support to interact with HTTP/1.1 servers.

Features

Supports GET, POST, PUT, HEAD, OPTIONS, DELETE methods, request and response headers/bodies, and redirection response handling.
Using this module, connections can be opened/closed to HTTP servers. Each connection is an instance which can be configured with a set of repeated requests/responses parameters so that they can be used across multiple transactions.
For supporting small memory devices, the module has been specially designed with split request/response APIs which enable sending requests and responses in smaller chunks, and static memory based APIs to eliminate the need for dynamic memory allocations.
Supports security features which include TLS and communication through proxy.
Supports two types of programming model: synchronous and asynchronous modes. In the default synchronous mode, an application uses APIs to make request to the server and blocks till the server responds. With asynchronous mode, a thread to handle the response is created which invokes callbacks registered with the module.
Supports TI-RTOS NDK, SimpleLink WiFi and Linux networking stacks. At IP level supports both IPv4 and IPv6.
Supports conditional compilation of the module to include/exclude some of the features mentioned above.

Limitations

HTTP client on SimpleLink WiFi supports IPv4 only.
HTTP client on TI-RTOS NDK does not support host name resolution. So the API HTTPCli_initSockAddr() does not resolve host name. The API can be used only if an IP string is passed instead of the host name.

### GET Example

#include <ti/net/http/httpcli.h>
HTTPCli_Struct cli;
// Construct a static instance
HTTPCli_construct(&cli);
// Connect to the HTTP Server
HTTPCli_connect(&cli, &addr, 0, NULL);
// Set request fields
HTTPCli_Field fields[2] = {
    { HTTPCli_FIELD_NAME_HOST,  "www.example.com" },
    { NULL, NULL }
};
HTTPCli_setRequestFields(&cli, fields);
// Set response field filters
char *respFields[2] = {
    HTTPCli_FIELD_NAME_CONTENT_LENGTH,
    NULL
};
HTTPCli_setResponseFields(&cli, respFields);
// Make HTTP 1.1 GET request
//
// Send request to the server:
//
// GET /index.html HTTP/1.1
// Host: www.example.com
// <blank line>
HTTPCli_sendRequest(&cli, HTTPCli_METHOD_GET, "/index.html", false);
// Get the processed response status
//
// HTTP/1.1 200 OK
//
status = HTTPCli_getResponseStatus(&cli);
// Check the HTTP return status and process remaining response
if (status == 200) {
 do {
 // Filter the response headers and get the set response field
 //
 // ...
 // Content-type: text/xml; charset=utf-8\r\n
 // Content-length: 34
 // ...
       ret = HTTPCli_getResponseField(&cli, buf, sizeof(buf), &moreFlag);
 // process data in buf if field is content length
 // Zero is the index of Content length in respFields array
 if (ret == 0) {
          len = (int)strtoul(buf, NULL, 0);
      }
 //loop till the end of the response fields
  } while (ret != HTTPCli_FIELD_ID_END);
 // Read message based on content length field value
 while (len > 0) {
      len -= HTTPCli_readRawResponseBody(&cli, buf, sizeof(buf));
 // process buf data and save
  }
}
// Close connection
HTTPCli_disconnect(&cli);
// Destroy the instance
HTTPCli_destruct(&cli);

POST Example

// Set request fields
HTTPCli_Field fields[2] = {
    { HTTPCli_FIELD_NAME_HOST,  "www.example.com" },
    { NULL, NULL }
};
HTTPCli_setRequestFields(&cli, fields);
// Set response field filters
char *respFields[2] = {
    HTTPCli_FIELD_NAME_CONTENT_LENGTH,
    NULL
};
HTTPCli_setResponseFields(&cli, respFields);
// Make HTTP 1.1 POST request
//
// Send request to the server:
//
// POST /index.html HTTP/1.1
// Host: www.example.com
HTTPCli_sendRequest(&cli, HTTPCli_METHOD_POST, "/index.html", true);
// Send additional fields
//
// Content-Length: <length>
// <blank line>
HTTPCli_sendField(&cli, HTTPCli_FIELD_NAME_CONTENT_LENGTH, len, true);
// Send request body
//
// <data>
HTTPCli_sendRequestBody(&cli, data, strlen(data));
// Get the processed response status
//
// HTTP/1.1 200 OK
//
status = HTTPCli_getResponseStatus(&cli);
// Check the HTTP return status and process remaining response
if (status == 200) {
 do {
 // Filter the response headers and get the set response field
 //
 // ...
 // Content-type: text/xml; charset=utf-8\r\n
 // Content-length: 34
 // ...
       ret = HTTPCli_getResponseField(&cli, buf, sizeof(buf), &moreFlag);
 // process data in buf if field is content length
 // Zero is the index of Content length in respFields array
 if (ret == 0) {
          len = (int)strtoul(buf, NULL, 0);
      }
 //loop till the end of the response fields
  } while (ret != HTTPCli_FIELD_ID_END);
 // Read message based on content length field value
 while (len > 0) {
      len -= HTTPCli_readRawResponseBody(&cli, buf, sizeof(buf));
 // process buf data and save
  }
}
// Close connection
