如何处理作为 HTTP Post 发送到 cakephp 应用程序的 json 数据? [英] How do I handle json data sent as an HTTP Post to a cakephp app?

问题描述

如果我收到一个 HTTP Post，其中 http 请求的正文只是一个 UTF8 编码的字符串，我如何在我的 cakephp 控制器中访问该数据?看起来 $this->params 只包含以下内容:

<代码>{经过":[]，命名":[]，"控制器":"用户","action":"签到",插件":空，网址":{"ext":"json","url":"用户/checkin.json"},形式":[]，"isAjax":false}

发布的数据如下所示:

<代码>{"sessionkey":"somecrazykey","经度":"-111.12345","纬度":"33.12345","reqtype":"签到","location":"商场",公开":真实"}

解决方案

if($this->RequestHandler->requestedWith('json')) {if(function_exists('json_decode')) {$jsonData = json_decode(utf8_encode(trim(file_get_contents('php://input'))), true);}if(!is_null($jsonData) 和 $jsonData !== false) {$this->data = $jsonData;}}

这是一个被提议放在核心的代码片段，见https://trac.cakephp.org/ticket/6125.也许这就是您要找的.

If I'm being sent an HTTP Post where the body of the http request is just a UTF8 encoded string, how do I access that data in my cakephp controller? It appears that $this->params only contains the following:

{
    "pass":[],
    "named":[],
    "controller":"users",
    "action":"checkin",
    "plugin":null,
    "url":{
        "ext":"json",
        "url":"users/checkin.json"
    },
    "form":[],
    "isAjax":false
}

The data being posted looks something like this:

{
    "sessionkey":"somecrazykey",
    "longitude":"-111.12345",
    "latitude":"33.12345",
    "reqtype":"checkin",
    "location":"the mall",
    "public":"true"
}

解决方案

if($this->RequestHandler->requestedWith('json')) {
    if(function_exists('json_decode')) {
        $jsonData = json_decode(utf8_encode(trim(file_get_contents('php://input'))), true);
    }

    if(!is_null($jsonData) and $jsonData !== false) {
        $this->data = $jsonData;
    }
}

This is a codesnippet which was proposed to be in the core, see https://trac.cakephp.org/ticket/6125. Maybe it's what you're looking for.
