發送請求file_get_content not working

Question

我想使用file_get_contents「發佈」到一個url並獲得auth令牌。我遇到的問題是它返回一個錯誤。

Message: file_get_contents(something): failed to open stream: HTTP request failed! HTTP/1.1 411 Length Required.

我不知道是什麼原因造成這一點，但需要幫助。這是功能。

public function ForToken(){ 
     $username = 'gettoken'; 
     $password = 'something'; 
     $url = 'https://something.com'; 
     $context = stream_context_create(array (
      'http' => array (
      'header' => 'Authorization: Basic ' . base64_encode("$username:$password"), 
      'method' => 'POST' 
      ) 
     )); 

     $token = file_get_contents($url, false, $context); 
     if(token){ 
      var_dump($token); 
     }else{ 
      return $resultArray['result'] = 'getting token failed'; 
     } 
    } 

我試過用POSTMAN，它的工作原理，所以唯一的問題是，爲什麼它沒有與file_get_contents一起工作。

Answer 1

我不能評論，因爲我的名聲;

在一些服務器file_get_content不可用......

您可捲曲嘗試像this

您的要求還沒有任何數據和內容長度丟失。

你可以試試這個：

public function ForToken(){ 
    $username = 'gettoken'; 
    $password = 'something'; 
    $url = 'https://something.com'; 

    $data = array('foo' => 'some data'); 
    $data = http_build_query($data); 

    $context_options = array (
    'http' => array (
     'method' => 'POST', 
     'header'=> "Content-type: application/x-www-form-urlencoded\r\n" 
      . "Authorization: Basic " . base64_encode("$username:$password") . "\r\n" 
      . "Content-Length: " . strlen($data) . "\r\n", 
     'content' => $data 
     ) 
    ); 

    $context = context_create_stream($context_options); 

    $token = file_get_contents($url, false, $context); 
    if(token){ 
     var_dump($token); 
    }else{ 
     return $resultArray['result'] = 'getting token failed'; 
    } 
}

Answer 3

RFC2616 10.4.12 http://tools.ietf.org/html/rfc2616#section-10.4.12

代碼：（不工作，見下文）

public function ForToken(){ 
$username = 'gettoken'; 
$password = 'something'; 
$url = 'https://something.com'; 
$context = stream_context_create(array (
'http' => array (
'header' => 'Authorization: Basic ' . base64_encode("$username:$password") . 'Content-Length: ' . strlen($url) . '\r\n', 
'method' => 'POST' 
) 
)); 
$token = file_get_contents($url, false, $context); 
if(token){ 
var_dump($token); 
}else{ 
return $resultArray['result'] = 'getting token failed'; 
} 
} 

第二個嘗試：

public function ForToken(){ 
$username = 'gettoken'; 
$password = 'something'; 
$url = 'https://something.com'; 
$context_options = array (
'http' => array (
'method' => 'POST', 
'header'=> "Content-type: application/x-www-form-urlencoded\r\n" . "Authorization: Basic " . base64_encode("$username:$password") . "Content-Length: " . strlen($url) . "\r\n", 
'content' => $url 
) 
); 
$context = stream_context_create($context_options); 
$token = file_get_contents($url, false, $context); 
if(token){ 
var_dump($token); 
}else{ 
return $resultArray['result'] = 'getting token failed'; 
} 
}

不能命令，所以我會這樣做。如果你使用郵差，你爲什麼不讓郵遞員爲你生成代碼。在郵遞員中，您可以在請求中點擊代碼，甚至可以選擇您想要的代碼語言。像cURL一樣的PHP：

$curl = curl_init(); 

curl_setopt_array($curl, array(
    CURLOPT_URL => "http://somthing.com/", 
    CURLOPT_RETURNTRANSFER => true, 
    CURLOPT_ENCODING => "", 
    CURLOPT_MAXREDIRS => 10, 
    CURLOPT_TIMEOUT => 30, 
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1, 
    CURLOPT_CUSTOMREQUEST => "POST", 
    CURLOPT_HTTPHEADER => array(
    "password: somthing", 
    "username: gettoken" 
), 
)); 

$response = curl_exec($curl); 
$err = curl_error($curl); 

curl_close($curl); 

if ($err) { 
    echo "cURL Error #:" . $err; 
} else { 
    echo $response; 
} 

希望這會有所幫助！
