AFNetworking 上傳文件

@第一種

    #pragma mark - AFNetworking上傳文件


- (void)didClickUploadButtonAction{  

    NSString *fileName = @"hmt";  
    //  確定需要上傳的文件(假設選擇本地的文件)  
    NSURL *filePath = [[NSBundle mainBundle] URLForResource:fileName withExtension:@"png"];  
    NSDictionary *parameters = @{@"name":@"額外的請求參數"};  
    AFHTTPRequestOperationManager *requestManager = [AFHTTPRequestOperationManager manager];  
    [requestManager POST:@"http://192.168.10.18:8080/AFNetworkingServer/upload" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {  

        /** 
         *  appendPartWithFileURL   //  指定上傳的文件

         *  fileName                //  指定上傳文件的原始文件名 
         *  mimeType                //  指定商家文件的MIME類型 
         */  
        [formData appendPartWithFileURL:filePath name:@"file" fileName:[NSString stringWithFormat:@"%@.png",fileName] mimeType:@"image/png" error:nil];  

    } success:^(AFHTTPRequestOperation *operation, id responseObject) {  

        [[[UIAlertView alloc] initWithTitle:@"上傳結果" message:[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]  delegate:self cancelButtonTitle:@"" otherButtonTitles:nil] show];  

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {  

        NSLog(@"獲取服務器響應出錯");  

    }];  

}  </pre> 


 @第二種:
    NSData *imageData = UIImagePNGRepresentation(image);


//轉碼成UTF-8  否則可能會出現錯誤  


NSString *URLTmp = [NSString stringWithFormat:@"%@%@",CGBaseURL,path];  

NSString *URLTmps = [URLTmp stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];  

URLTmp = URLTmps;  

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:URLTmp parameters:body constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {  

    [formData appendPartWithFileData:imageData name:@"headerImg" fileName:@"123.png" mimeType:@"image/png"];  

} error:nil];  



AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];  

NSProgress *progress = nil;  


manager.responseSerializer = [AFHTTPResponseSerializer serializer];  


NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {  

    if (error) {  

        NSLog(@"Error: %@", error);  

    } else {  

        block(responseObject);  
    }  

}];  


[uploadTask resume];  </pre>
