PHP-解析JSON有效载荷问题

我正在通过HTTP POST回呼到PHP页面接收一些JSON,但是在解析JSON时遇到问题。这是发送的JSON数据的示例:

[
  {
    "type"        : "message-received",
    "time"        : "2016-09-14T18:20:16Z",
    "description" : "Incoming message received",
    "to"          : "+12345678902",
    "message"     : {
      "id"            : "14762070468292kw2fuqty55yp2b2",
      "time"          : "2016-09-14T18:20:16Z",
      "to"            : ["+12345678902"],
      "from"          : "+12345678901",
      "text"          : "Hey, check this out!",
      "applicationId" : "93de2206-9669-4e07-948d-329f4b722ee2",
      "media"         : [
        "https://messaging.bandwidth.com/api/v2/users/{accountId}/media/14762070468292kw2fuqty55yp2b2/0/bw.png"
        ],
      "owner"         : "+12345678902",
      "direction"     : "in",
      "segmentCount"  : 1
    }
  }
]

然后,我将按照以下方式进行处理:

$eventJSON = file_get_contents('php://input');
$event= json_decode( $eventJSON ); 
$eventType = $event->type;

但是我的$eventType变量到目前为止还没有得到什么-我认为问题可能在于JSON是一个数组,但是我不确定如何处理?

答案 0 :(得分:4)

要解析json,请尝试

$eventType = $event[0]->type;
