问题描述：

我有一个接收webhook数据的问题。 Wobhook数据以JSON格式发送这样的：使用json的webook php

{ 
"event_name": "chat_finished", 
"chat_id": 5302, 
"widget_id": "9IpBqsF7Mt", 
"visitor": { 
    "name": "v", 
    "email": "", 
    "phone": "", 
    "number": 106597, 
    "chats_count": 2 
}, 
"chat": { 
    "messages": [ 
     { 
      "timestamp": 1500275477, 
      "type": "visitor", 
      "message": "<Message text is not displayed here>" 
     }, 
     { 
      "timestamp": 1500275823, 
      "type": "visitor", 
      "message": "<Message text is not displayed here>" 
     }, 
     { 
      "timestamp": 1500275896, 
      "type": "visitor", 
      "message": "<Message text is not displayed here>" 
     }, 
     { 
      "timestamp": 1500276056, 
      "type": "visitor", 
      "message": "<Message text is not displayed here>" 
     } 
    ], 
    "rate": null 
}, 
"session": { 
    "geoip": { 
     "region_code": "26", 
     "country_code": "UA", 
     "country": "Ukraine", 
     "region": "Zaporiz'ka Oblast'", 
     "city": "Zaporizhzhya", 
     "isp": "", 
    }, 
    "utm": null, 
    "user_agent": "Mozilla\/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit\/537.36 (KHTML, like Gecko) Chrome\/59.0.3071.115 Safari\/537.36" 
}

}

在我的PHP脚本我有这样的代码：

$data = json_decode(file_get_contents("php://input"),true); 
$data = json_decode($data,true); 
var_dump($data); 
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!"); 
fwrite($myfile, $data); 
fclose($myfile); 
var_dump($_GET); 
var_dump($_POST); 
var_dump($_REQUEST);

在网络API日志文件中我看到，我的代码以某种方式获取webhook：

响应代码：200，持续时间：265毫秒，错误：意外的令牌< JSON在位置0

但是我不明白屏幕上的任何文字和所有的数组都是空的：

NULL array(0) { } array(0) { } array(0) { }

我该怎么做？感谢advnce。

答

，因为你运行json_decode（）两次试试这个

$contents = file_get_contents("php://input"); 
$data = json_decode($contents, true); 
var_dump($data);

感谢您指出我的错误。 –

使用json的webook php
