先说几个异常：
Required request part 'file' is not present
Required request part param is not present
Spring File Upload - 'Required request part is not present'
如果你使用php，对接api端的上传文件接口，包括java接口等，出现以上问题，只需要处理相应的参数即可。
header头，可以不写Content-Type:multiple/form-data
上传的文件地址，请务必要进行CURLFile处理。
代码贴下做参考：
$resource = $_SERVER['DOCUMENT_ROOT'].'/files/aaa.jpg'; $headers = ["header"=>array('Authorization:'.$ysyToken)]; $ysyData['file'] = new \CURLFile($resource); $result = CurlToolkit::requestYsyApi('POST','www.baidu.com',$ysyData,$headers);curl函数也贴出来做参考
public static function requestYsyApi($method, $url, $params = array(), $conditions = array()) { $conditions['userAgent'] = isset($conditions['userAgent']) ? $conditions['userAgent'] : ''; $conditions['connectTimeout'] = isset($conditions['connectTimeout']) ? $conditions['connectTimeout'] : 10; $conditions['timeout'] = isset($conditions['timeout']) ? $conditions['timeout'] : 10; $curl = curl_init(); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl, CURLOPT_USERAGENT, $conditions['userAgent']); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $conditions['connectTimeout']); curl_setopt($curl, CURLOPT_TIMEOUT, $conditions['timeout']); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); if(isset($conditions['header']) && $conditions['header']){ curl_setopt($curl, CURLOPT_HEADER, 0); }else{ curl_setopt($curl, CURLOPT_HEADER, 1); } if ($method == 'POST') { curl_setopt($curl, CURLOPT_POST, 1); //TODO curl_setopt($curl, CURLOPT_POSTFIELDS, $params); } elseif ($method == 'PUT') { curl_setopt($curl,CURLOPT_HTTPHEADER,array("X-HTTP-Method-Override: $method"));//设置HTTP头信息 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PUT'); curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($params)); } elseif ($method == 'DELETE') { curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'DELETE'); curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($params)); } elseif ($method == 'PATCH') { curl_setopt($curl, CURLOPT_CUSTOMREQUEST, 'PATCH'); curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($params)); } else { if (!empty($params)) { $url = $url.(strpos($url, '?') ? '&' : '?').http_build_query($params); } } if(isset($conditions['header']) && $conditions['header']){ curl_setopt($curl, CURLOPT_HTTPHEADER, $conditions['header']); } curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLINFO_HEADER_OUT, true); $response = curl_exec($curl); $curlinfo = curl_getinfo($curl); curl_close($curl); if (empty($curlinfo['namelookup_time'])) { return array(); } if (isset($conditions['contentType']) && $conditions['contentType'] == 'plain') { return $response; } $body = json_decode($response, true); return $body; }
