php - {"error":"invalid multipart format"} 这是什么原因，我已经在HEADER中设置了Content-type:multipart/form-data
用CULR向七牛的API上传文件 每次总是invalid multipart format 但是我已经设置了Content-type:multipart/form-data呀
function uploadFile($localPath, $remoteFileName, $headers=array()){
global $conf;
$remoteFileName = trim($remoteFileName,'/');
$policy = array('scope' => $conf['bucket'] . ':' . $remoteFileName, 'deadline' => time() + 3600);
$encodedFlags = encode(json_encode($policy));
$sign = hash_hmac('sha1', $encodedFlags, $conf['sk'], true);
$encodedSign = encode($sign);
$token = $conf['ak'].':'.$encodedSign. ':' . $encodedFlags;
$fields = array(
'token' => $token,
'key' => $remoteFileName,
'file' => '@'.$localPath
);
$curl = Magecho_HttpClient::get();
$curl->setOptions(array('gzip'=>false))->setHeader(array(
'Content-type:multipart/form-data'
))->post($conf['host']['up'] ,$fields);
return $curl->response();
}
function encode($str) {
$find = array('+', '/');
$replace = array('-', '_');
return str_replace($find, $replace, base64_encode($str));
}
$result = uploadFile('pic.jpg',date('Y-m-d-H-i-s').'.jpg');
echo $result;
