问题描述

根据应用程序需求，我正在尝试开发两个可以通过Json相互通信的PHP.我尝试在线搜索，但未找到解决方案.

As per application requirement, I am trying to develop two PHP which can communicate with each other via Json. I tried searching online but didn't found solution.

有人可以建议我这样做的正确方法吗?

Can any one suggest me the right path for this?

我在mysql数据库中有数据，转换后的数据将为json格式，如下所示:(还寻找通过PHP-JSON对象和数组获取此数据格式的代码.)

I have data in mysql database, the converted data will be in json format as given below: (Also looking for code to get this data format via PHP-JSON object and array.)

{ "user" : [   
             { "firstName" : "Vignesh",  
               "lastName"  : "Prajapati",
               "age"       : 23,
               "email"     : ["[e-mail]","[e-mail]"],
               "subject"   : ["English","Gujarati", "Hindi"]
             }, 

             { "firstName" : "Vaibhav",  
               "lastName"  : "Prajapati",
               "age"       : 19,
               "email"     : ["[e-mail]","[e-mail]","[e-mail]"],
               "subject"   : ["English","Spanish", "Chinese","Sanskrit"]
             }
           ]
} 

我用于发送Json数据的Php代码:(send.php)

My Php code for sending Json data: (send.php)

<?php

$data = '    { "user" : [   
                 { "firstName" : "Vignesh",  
                   "lastName"  : "Prajapati",
                   "age"       : 23,
                   "email"     : ["[e-mail]","[e-mail]"],
                   "subject"   : ["English","Gujarati", "Hindi"]
                 }, 

                 { "firstName" : "Vaibhav",  
                   "lastName"  : "Prajapati",
                   "age"       : 19,
                   "email"     : ["[e-mail]","[e-mail]","[e-mail]"],
                   "subject"   : ["English","Spanish", "Chinese","Sanskrit"]
                 }
               ]
    } ';

$url_send ="http://localhost/rec.php";
$str_data = json_encode($data);

function sendPostData($url, $post){
  $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
  $result = curl_exec($ch);
  curl_close($ch);  // Seems like good practice
  return $result;
}

echo " " . sendPostData($url_send, $str_data);

?>

我用于接收Json数据的Php代码:(rec.php)

My Php code for receiving Json data: (rec.php)

<?php

$json_input_data=json_decode(file_get_contents('php://input'),TRUE);

echo $json_input_data;


?>

推荐答案

修改您的函数以在发布请求中发送JSON_DATA的标头

Modify your function to send header of JSON_DATA in post request

function sendPostData($url, $post){
 $ch = curl_init($url);
  curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($post))                                                                       
   );  
  $result = curl_exec($ch);
  curl_close($ch);  // Seems like good practice
  return $result;
}

在文件中使用

<?php

$json_input_data=json_decode(file_get_contents('php://input'),TRUE);

print_r( $json_input_data);


?>

每个人都说不需要$str_data = json_encode($data);，因为数据已经在json中了.

As everyone said there is no need of $str_data = json_encode($data);,Since data is already in json.
