AFNetworking 3.0用于上传图像错误的多部分表单数据
我一直在尝试使用multipart表单数据networking3.0将图像上传到我的AWS服务器，但显然，我试图上传的每个图像都以失败模块结束。 代码写在objective-c中。
- (NSURLSessionUploadTask *)uploadImageTask:(NSMutableDictionary *)dictionary { NSString *s3BucketUrl = [dictionary objectForKey:@"s3BucketUrl"]; NSData *imageData = [dictionary objectForKey:@"imageData"]; NSString *contentType = [dictionary objectForKey:@"contentType"]; NSString *filename = [dictionary objectForKey:@"filename"]; NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:s3BucketUrl parameters:dictionary constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileData:imageData name:@"file" fileName:filename mimeType:contentType]; } error:nil]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSURLSessionUploadTask *uploadTask = [[NSURLSessionUploadTask alloc] init]; uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) { // This is not called back on the main queue. // You are responsible for dispatching to the main queue for UI updates dispatch_async(dispatch_get_main_queue(), ^{ //Update the progress view }); } completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (!error) { if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)]) { [self.delegate onUploadImageTask:nil]; } } else { if (self.delegate != nil && [self.delegate respondsToSelector:@selector(onUploadImageTask:)]) { [self.delegate onUploadImageTask:error]; } } }]; [uploadTask resume]; return uploadTask; } 我得到的错误是
Error Domain = com.alamofire.error.serialization.response Code = -1011“Request failed：bad request（400）”UserInfo = {NSUnderlyingError = 0x170248940 {Error Domain = com.alamofire.error.serialization.response Code = -1016“请求失败：不可接受的内容types：application / xml“UserInfo = {com.alamofire.serialization.response.error.response = {URL： https：//….s3.amazonaws.com/ } {status code：400 ，标题{连接=closures; “Content-Type”=“application / xml”; date=“2016年12月20日星期二01:53:47 GMT”; 服务器= AmazonS3; “Transfer-Encoding”=身份; “x-amz-id-2”=“…..”; “x-amz-request-id”= ….; }}，
我试着改变响应串行器的内容types，但仍然失败。
使用这种方法
-(void)callWebserviceToUploadImageWithParams:(NSMutableDictionary *)_params imgParams:(NSMutableDictionary *)_imgParams videoParms:(NSMutableDictionary *)_videoParams action:(NSString *)_action success:(void (^)(id))_success failure:(void (^)(NSError *))_failure { if ([[AFNetworkReachabilityManager sharedManager] isReachable]) { //Here BASE_URL is my URL of web service NSString *urlString = [BASE_URL stringByAppendingString:_action]; NSLog(@"URL : %@",urlString); NSMutableURLRequest *urlRequest = [[NSMutableURLRequest alloc] init]; [urlRequest setURL:[NSURL URLWithString:urlString]]; [urlRequest setHTTPMethod:@"POST"]; NSString *boundary = @"---------------------------14737809831466499882746641449"; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; [urlRequest addValue:contentType forHTTPHeaderField: @"Content-Type"]; // [urlRequest setValue:contentType forHTTPHeaderField:@"Content-type: application/json"] NSMutableData *body = [NSMutableData data]; [_params enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSString *object, BOOL *stop) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n",key] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"%@",object] dataUsingEncoding:NSUTF8StringEncoding]]; }]; [_imgParams enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSData *object, BOOL *stop) { if ([object isKindOfClass:[NSData class]]) { if (object.length > 0) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"Timestamp:%@",TimeStamp); [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@.jpg\"\r\n",key,TimeStamp] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:object]]; } } }]; [_videoParams enumerateKeysAndObjectsUsingBlock: ^(NSString *key, NSData *object, BOOL *stop) { if (object.length > 0) { [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; NSLog(@"Timestamp:%@",TimeStamp); [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"%@.mp4\"\r\n",key,TimeStamp] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[[NSString stringWithFormat:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [body appendData:[NSData dataWithData:object]]; } }]; [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [urlRequest setHTTPBody:body]; AFHTTPSessionManager* manager = [AFHTTPSessionManager manager]; manager.responseSerializer.acceptableContentTypes = nil; NSURLSessionDataTask *dataTask = [manager dataTaskWithRequest:urlRequest completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) { if (error) { NSLog(@"Error: %@", error); if( _failure ) { _failure( error) ; } } else { if( _success ) { _success( responseObject ) ; } } }]; [dataTask resume]; } else { [Utility showInterNetConnectionMessage]; NSError *error; if( _failure ) { _failure( error) ; } } }
如果你没有上传任何video或图像，然后作为零
使用：
#pragma -mark callwebservice for login -(void)callWebserviceFor_upload_Sticker { // Check whether Company user login or Individual User login. [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeClear]; //user_id, user_token, emoji_weburl(optional), emoji_picture(file) NSMutableDictionary *dict_user_data = [Utility getUserPlistData]; NSMutableDictionary *params = [[NSMutableDictionary alloc]init]; [params setValue:[dict_user_data valueForKey:@"user_id"] forKey:@"user_id"]; [params setValue:[dict_user_data valueForKey:@"user_token"] forKey:@"user_token"]; NSLog(@"%@",params); NSMutableDictionary *imgParams = [[NSMutableDictionary alloc]init]; [imgParams setValue:UIImageJPEGRepresentation(img_to_upload, 0) forKey:@"emoji_picture"]; void ( ^successed )( id _responseObject ) = ^( id _responseObject ) { NSLog(@"%@",_responseObject); //Your logic after success } ; void ( ^failure )( NSError* _error ) = ^( NSError* _error ) { [SVProgressHUD showErrorWithStatus:@"Failed"]; } ; [[WebServiceHendler sharedManager]callWebserviceToUploadImageWithParams:params imgParams:imgParams videoParms:nil action:UPDATE_EMOJI success:successed failure:failure]; }
