的file_get_contents不工作的使用批次要求

Question

的file_get_contents不是使用下面的代碼使用批處理requests.Am從Facebook獲取FATA工作從Facebook獲取數據：

$url='https://graph.facebook.com/?batch=[{ "method": "POST", "relative_url":"method/fql.query?query=SELECT+first_name+from+user+where+uid=12345678"}]& access_token=xxxxxxx&method=post'; 
echo $post = file_get_contents($url,true); 
it produces 
    Warning: file_get_contents(graph.facebook.com/?batch=[{ "method": "POST", "relative_url": "method/fql.query?query=SELECT+first_name+from+user+where+uid=12345"}]&access_to‌ ​ken=xxxx&method=post): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request in /home/user/workspace/fslo/test.php on line 9 

Answer 1

我要說最有可能的答案，這是您需要通過urlencode()傳遞URL值 - 特別是JSON字符串。

此外，您應該是POST ing數據。

試試這個代碼：

注：我想你是從幾個變量建設的URL。如果你與你的實際代碼編輯的問題，我將使用代碼

<?php 

    $baseURL = 'https://graph.facebook.com/'; 

    $requestFields = array (
    'batch' => '[{"method":"POST","relative_url":"method/fql.query?query=SELECT+first_name+from+user+where+uid=12345678"}]', 
    'access_to‌ken' => 'whatever' 
); 
    $requestBody = http_build_query($requestFields); 

    $opts = array(
    'http'=>array(
     'method' => 'POST', 
     'header' => "Content-Type: application/x-www-form-urlencoded\r\n" 
       . "Content-Length: ".strlen($requestBody)."\r\n" 
       . "Connection: close\r\n", 
     'content' => $requestBody 
    ) 
); 

    $context = stream_context_create($opts); 

    $result = file_get_contents($baseURL, FALSE, $context); 

A「多標準」的方式做到這一點，這些天提供的解決方案是捲曲：

<?php 

    $baseURL = 'https://graph.facebook.com/'; 

    $requestFields = array (
    'batch' => '[{"method":"POST","relative_url":"method/fql.query?query=SELECT+first_name+from+user+where+uid=12345678"}]', 
    'access_to‌ken' => 'whatever' 
); 
    $requestBody = http_build_query($requestFields); 

    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $baseURL); 
    curl_setopt($ch, CURLOPT_POST, TRUE); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, $requestBody); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/x-www-form-urlencoded', 
    'Content-Length: '.strlen($requestBody), 
    'Connection: close' 
)); 

    $post = curl_exec($ch);
