Slim PUT返回NULL [英] Slim PUT returns NULL

问题描述

我遇到了Slim Framework和PUT请求的问题。我有一个小小的jQuery脚本，它会在点击一个按钮时更新到期时间。

I have a problem with the Slim Framework and a PUT request. I have a litte jQuery script that that will update an expiry time when a button is clicked.

$("#expiry-button").click(function(event) {
     event.preventDefault();

     $.ajax({
         url: 'http://www.domain.com/expiry/38/', 
         dataType: 'json',
         type: 'PUT',
         contentType: 'application/json',
         data: {aid:'38'},
         success: function(){
             var text = "Time updated";
             $('#expiry').text(text).addClass("ok");
          },
          error: function(data) { 
             var text = "Something went wrong!";
             $('#expiry').text(text).addClass("error");
           }
     });
});

我总是得到出了问题！

在我配置了Slim的index.php中，我有这个

In my index.php where I have configured Slim, I have this

$app->put('/expiry/:aid/', function($aid) use($app, $adverts) {
    $id = $app->request()->put($aid);
    $adverts->expand_ad_time($id["aid"]);
}); 

如果我 var_dump（$ id） I获取NULL

if I var_dump($id) I get NULL

响应标头如下所示：

和请求正文

Request Url: http://www.domain.com/expiry/38/
Request Method: PUT
Status Code: 200
Params: {
    "aid": "38"
}

所以沟通在那里，但不是理想的结果。我做错了什么？

So the communication is there, but not the desired result. What am I doing wrong?

推荐答案

首先你应该检查一下json数据，因为它无效： http://jsonlint.com/
试试这个：{aid：38}

First you should check that json data, because it isn't valid: http://jsonlint.com/ Try with this: {"aid":"38"}

如果您需要JSON数据而不是我会这样做：

If you need that JSON data than i would do something like this:

$app->put('/expiry/:aid/', function($aid) use($app, $adverts) {
    // Decode the request data
    $test = json_decode($app->getInstance()->request()->getBody());
    echo $test->aid; // from the JSON DATA
}); 

如果你想要url / expiry / 38 /的数字，那么，你可以从变量$ aid获得它，你已经传递给函数

If you want the number from the url /expiry/38/ then, you can get it from the variable $aid, which you've passed to the function

$app->put('/expiry/:aid/', function($aid) use($app, $adverts) {
    echo $aid; // from the url
});

我希望这可以帮到你
