我正在尝试使用RESTful Web服务上传文件,如下所示:
$filename = "pathtofile/testfile.txt";
$handle = fopen($filename, "r");
$filecontents = fread($handle, filesize($filename));
fclose($handle);
$data = array('name' => 'testfile.txt', 'file' => $filecontents);
$client = curl_init($url);
curl_setopt($client, CURLOPT_POST, true);
curl_setopt($client, CURLOPT_POSTFIELDS, $data);
curl_setopt($client, CURLOPT_RETURNTRANSFER, 1);
curl_close($client);
但我保持gettig文件为空,作为对此请求的响应.
我也试过发送文件路径,如:
$data = array('name' => 'testfile.txt', 'file' => 'pathtofile/testfile.txt');
curl_setopt($client, CURLOPT_POSTFIELDS, $data);
curl_setopt($client, CURLOPT_POSTFIELDS, $filecontents);
但是同样的反应:文件是空的.
请注意:文件存在且不为空,我只是尝试仅上传文件而没有其他字段.
我看到this post,但同样的问题,任何想法?
解决方法:
试试这个:
$data = array ('myfile' => '@'.$filename);
这将为接收端填充$_FILE [‘myfile’].
//Get the file data
$body = file_get_contents ($filename);
$len = strlen ($body);
//Open a direct connection to the server on port 80
$socket = fsockopen ('hostname.example.com', 80);
//Write the HTTP request headers
fwrite ($socket, "POST /path/to/url HTTP/1.1\r\n");
fwrite ($socket, "Host: hostname.example.com\r\n");
fwrite ($socket, "Connection: Close\r\n");
fwrite ($socket, "Content-Length: " . $len . "\r\n");
//Empty line marks end of headers, start of body
fwrite ($socket, "\r\n");
//Actually write the body
fwrite ($socket, $body);
//Get the result (half a kB at a time)
$result = '';
while (!feof ($socket)) $result .= fread ($socket, 512);
//Clean up nicely
fclose ($socket);
请注意,该代码未经测试,但它应该为您提供一般的想法.
