是否可以使用cURL来上传使用POST文件？

Question

或者PHP不允许这样做？我已经读过它可以使用PUT，但服务器仅期望POST。

Answer 1

是的，它有可能流上传一个文件使用POST文件上传与cURL。这是默认设置，您需要提供想要以字符串形式流式传输的文件的文件名。

// 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; 

除此之外默认方法，它是不可以使用卷曲到流上传使用POST方法的文件。

卷曲已经支持流，尝试curl --help | grep binary你会得到：

“--data-二进制数据HTTP POST二进制数据（H）”

一个例子： curl -v -XPOST http://example:port/path --data-binary @file.tar \ -H "Content-Type: application/octet-stream"
