PHP 中的 PUT 请求使用 file_get_contents 的错误请求

Bad request using file_get_contents for PUT request in PHP

这个 api 调用使用 Postman(一个 REST 客户端)工作正常, 但是在我的 GAE 应用程序中向服务器发出请求时,我目前收到以下错误:

HTTP request failed! in C:\Projects\app\file.php on line 26

failed to open stream: HTTP request failed! HTTP/1.0 400 Bad Request in C:\Projects\app\file.php on line 26

这是我的应用程序的代码,它调用了其余 api 方法 /exampleMethod

$dataraw = [ 
        'email' => 'email@ex.com',
        'first_name' => 'firstname',
        'last_name' => 'lastname',
        'fEmail' => 'email@ex.com',
        'message' => 'test' 
];
$data = http_build_query ( $dataraw );
$context = [ 
        'http' => [ 
                'method' => 'PUT',
                'header' => "Authorization: apikeystring\r\n" . "Content-Length: " . strlen($data) . "\r\n" . "Content-Type: application/json\r\n",
                'content' => $data,
                'proxy' => 'tcp://euproxy.example.com:0000' 
        ] 
];
$context = stream_context_create ( $context );
$result = file_get_contents ( $GLOBALS ['REST_API_URL'] . '/exampleMethod', false, $context );

在应用程序中,我已成功将 file_get_contents 用于 GET 请求,但对于此 PUT 请求,我收到一个 400 错误请求,该请求不是来自 Rest Api。

将 mb_strlen(serialize($dataraw), '8bit') 更改为 strlen($data)
