是否可以使用cURL來上傳使用POST文件？

Question

或者PHP不允許這樣做？我已經讀過它可以使用PUT，但服務器僅期望POST。

Answer 1

是的，它有可能流上傳一個文件使用POST文件上傳與cURL。這是默認設置，您需要提供想要以字符串形式流式傳輸的文件的文件名。

// URL on which we have to post data 
$url = "http://localhost/tutorials/post_action.php"; 
// Any other field you might want to catch 
$post_data['name'] = "khan"; 
// File you want to upload/post 
$post_data['file'] = "@c:/logs.log"; 

// Initialize cURL 
$ch = curl_init(); 
// Set URL on which you want to post the Form and/or data 
curl_setopt($ch, CURLOPT_URL, $url); 
// Data+Files to be posted 
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data); 
// Pass TRUE or 1 if you want to wait for and catch the response against the request made 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
// For Debug mode; shows up any error encountered during the operation 
curl_setopt($ch, CURLOPT_VERBOSE, 1); 
// Execute the request 
$response = curl_exec($ch); 

// Just for debug: to see response 
echo $response; 

除此之外默認方法，它是不可以使用捲曲到流上傳使用POST方法的文件。

捲曲已經支持流，嘗試curl --help | grep binary你會得到：

「--data-二進制數據HTTP POST二進制數據（H）」

一個例子： curl -v -XPOST http://example:port/path --data-binary @file.tar \ -H "Content-Type: application/octet-stream"
