我一直收到这个错误 file_get_contents(failed to open stream: HTTP request failed! HTTP/1.1 400 BAD REQUEST

I keep getting this error file_get_contents(failed to open stream: HTTP request failed! HTTP/1.1 400 BAD REQUEST

我正在关注 Instagram 教程。我已经检查了我的代码大约一个小时,但似乎找不到问题所在。我不断收到以下错误

 file_get_contents(https://api.instagram.com/v1/media/search?lat33.810485&lng=-117.918989&client_id=b2b2dccbfc432681097): failed to open stream: HTTP request failed! HTTP/1.1 400 BAD REQUEST

(查看: /home/vagrant/Code/api/resources/views/welcome.blade.php)

它指向第十三行

标记为

我看到了所有内容。我正在使用 laravel 5.1。一切似乎都是最新的。这是我的代码

<?php
    if(!empty($_GET['location'])){
        $maps_url = 'https://maps.googleapis.com/maps/api/geocode/json?address='.urlencode($_GET['location']);

     $maps_json = file_get_contents($maps_url);  
        $maps_array = json_decode($maps_json, true);

        $lat = $maps_array['results'][0]['geometry']['location']['lat'];
        $lng = $maps_array['results'][0]['geometry']['location']['lng'];

        $instagram_url = 'https://api.instagram.com/v1/media/search?lat'.$lat.'&lng='.$lng.'&client_id=b2b2dccbfc432681097';

        $instagram_json = file_get_contents($instagram_url);
        $instagram_array = json_decode($instagram_json, true);

    }
    ?>

我们将不胜感激。

这是你的问题:

$maps_url = 'https://maps.googleapis
  .com/maps/api/geocode/json?address='.
  urlencode($_GET['location']);

您的地址中有换行符(和一些空格)。这是将地址传递给 file_get_contents():

时的样子
'https://maps.googleapis\n      .com/maps/api/geocode/json?address='

您可以通过将其拆分为两个字符串或将其放在一行来解决此问题:

$maps_url = 'https://maps.googleapis' .
  '.com/maps/api/geocode/json?address='.
  urlencode($_GET['location']);

instagram URL 也有同样的问题。

当我复制和粘贴代码时,uri 中出现了拼写错误。它缺少 lat 键值对

的等号

Instagram 已更改 api。您不能再在端点中使用 client_id。相反,您必须请求身份验证、接收访问令牌并传递此访问令牌而不是 client_id。
