Post requests for multiple data encoding methods using curl under PHP code

PHP uses Curl request data is very common, but according to the http/1.1 protocol in the post submission data encoding method, the use of Curl function parameters of the choice is also different.
The Content-type in the header headers of the request message is labeled as the transmission encoding for service-side identification, and the following content-type are used to transmit data correctly according to the different Curl

I. application/x-www-form-urlencoded mode:

1. Common similar Web form data:
Curl Method:

Public Function Curl_post ($data, $url) {
    $ch = Curl_init ();

    curl_setopt ($ch, Curlopt_url, $url);
    curl_setopt ($ch, Curlopt_customrequest, "POST");
    curl_setopt ($ch, Curlopt_ssl_verifypeer, FALSE);
    curl_setopt ($ch, Curlopt_ssl_verifyhost, FALSE);
    curl_setopt ($ch, Curlopt_useragent, ' mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0) ');
    curl_setopt ($ch, curlopt_followlocation, 1);
    curl_setopt ($ch, Curlopt_autoreferer, 1);
    curl_setopt ($ch, Curlopt_postfields, $data);
    curl_setopt ($ch, Curlopt_returntransfer, true);
    $tmpInfo = curl_exec ($ch);
    if (Curl_errno ($ch)) {
    echo ' errno '. Curl_error ($ch);
    }
    Curl_close ($ch);
    return $tmpInfo;
}

Processing Example:

Request:

Public Function Test2 () {            
        $template = array (
            ' touser ' => ' test1 ', '
            template_id ' => ' one ', '
            url ' = > ' http://www.test.com ',
            ' topcolor ' => ' #EEEEEE ',
            ' data ' => array (' T1 ', ' T2 ', ' T3 ')
        ;
        $data = $template;   
        $url = "Http://127.0.0.1/jytest/test1";
        $this->curl_post ($data, $url);    
    

Receive processing:

Public Function test1 () {      
      $res = $_post;
      $content = ';
      $content = $content. $res [' Touser ']. ', ';
      $content = $content. $res [' template_id ']. ', ';
      $content = $content. $res [' url ']. ', ';
      $content = $content. $res [' Topcolor ']. ', ';
      $content = $content. Serialize ($res [' Data ']). ', ';
      $filePath = "./test.txt";      
      File_put_contents ($filePath, $content);

    }

Test.txt file contents are: Test1, one, http://www.test.com, #EEEEEE, s:5: "Array";

You can see that the submitted array is not properly received
If you want to pass an array, you will use the Curl_post method in the

curl_setopt ($ch, Curlopt_postfields, $data);

To

curl_setopt ($ch, Curlopt_postfields, Http_build_query ($data));

2. JSON, using the above Curl_post method unchanged, just the JSON content as a string content delivery, to have a header field name corresponding to it, to receive

Processing Example:

Public Function Test2 () {
    //requestor
    $template = Array (
        ' touser ' => ' test1 ',
        ' template_id ' => ' 11 ',
        ' url ' => ' http://www.test.com ', '
        topcolor ' => ' #EEEEEE ',
        ' data ' => array (' T1 ', ' T2 ',
    ' T3 ') ;
    $data [' data '] = Json_encode ($template);
    $url = "Http://127.0.0.1/test/test1";
    $res =  $this->curl_post ($data, $url);
    Print_r (Json_decode ($res, 1));

 }

Receive processing:

Public Function test1 () {
     //Receive processing return
      $data = Json_decode ($_post[' data '],true);    
      $content =serialize ($data);
      $filePath = "./test.txt";      
      File_put_contents ($filePath, $content);    
    }

The contents of the Test.txt file are:
A:5:{s:6: "Touser"; s:3: "Test1"; s:11: "template_id"; S:2: "One"; s:3: "url"; s:19: "http://www.test.com"; s:8: "Topcolor"; s:7: "#EEEEEE"; s:4: "Data"; A:3:{i:0;s:2: "T1"; I:1;s:2: "T2"; I:2;s:2: "T3";}}
Can be seen as the contents of the array $template

two. Direct Application/json mode:

Curl Set Header to Content-type to Application/json

Curl method

Private Function Curl_postjson ($data, $urlcon) {
        $ch = Curl_init ($urlcon);//Request URL address
        curl_setopt ($ch, curlopt _customrequest, "POST");
        curl_setopt ($ch, Curlopt_postfields, $data);//$data JSON type string
        curl_setopt ($ch, Curlopt_returntransfer, true);
        curl_setopt ($ch, Curlopt_httpheader, Array (' Content-type:application/json ', ' content-length: '. strlen ($data)));
        $tmpInfo = curl_exec ($ch);
        Curl_close ($ch);
        return $tmpInfo;
    }

Request:

Public Function Test2 () {      
      //requestor
      $template = Array (
            ' touser ' => ' test1 ',
            ' template_id ' => ' 11 ',
            ' url ' => ' http://www.test.com ', '
            topcolor ' => ' #EEEEEE ',
            ' data ' => array (' T1 ', ' T2 ',
        ' T3 ') ;

      You do not need a separate field name for the JSON array, and the server receives the
      $data = Json_encode ($template) with file_get_contents (' php://input ');  
      $url = "Http://127.0.0.1/test/test1";    
      $res = $this->curl_postjson (Json_encode ($data), $url);
      Print_r (Json_decode ($res, 1));

    }

Receive processing:

Public Function test1 () {     
      $filePath = "./test.txt";   
      You do not need to use field names to receive JSON arrays
      $res =  file_get_contents (' php://input '); 
      $res = Json_decode ($res, 1);
      $content = serialize ($res);
      File_put_contents ($filePath, $content);
      echo Json_encode ($res);

    }

The

Test.txt file contents are:
s:110: "{touser": "Test1", "template_id": "One", "url": "Http:\/\/www.test.com", "Topcolor": "# Eeeeee "," Data ": [" T1 "," T2 "," T3 "]}";
