iPhone使用AFNetworking上传多部分文件

在我的iOS应用程序中，我想使用NSMutableURLRequest为多部分文件使用java API上传文件。 这里是显示参数的forms。

  <form action="API_URL" encType='multipart/form-data' method=post> <input type=file name="files"> <input type=submit value="Upload Attempt Files"> 

编辑form2

  <form action='URL' method="post" encType='multipart/form-data'> <input name="key1" value='123'> <input name="key2" value='asdf'> <input name="key3" value='qwerty'> <input name="key4" value='aaa'> <input name="key5" value='aaa'> <input name="key6" value='false'> <input type="file" name="files"> <input type=submit value="Create Forum Posts"> </form> 

我怎样才能做到这一点。

这里的这个问题展示了如何在iOS中使用AFNetworking （目标c）上传多部分文件。 但我没有得到如何把参数按照我使用的forms。

请帮助和build议

Answer 1

看看你的HTML，你的<input type=file>的name是files ，因此你可以使用@"files"作为appendPartWithFileData方法的name参数。 例如，使用AFNetworking 3.x ：

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; [manager POST:urlString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileData:imageData name:@"files" fileName:photoName mimeType:@"image/jpeg"]; [formData appendPartWithFormData:[key1 dataUsingEncoding:NSUTF8StringEncoding] name:@"key1"]; [formData appendPartWithFormData:[key2 dataUsingEncoding:NSUTF8StringEncoding] name:@"key2"]; // etc. } progress:nil success:^(NSURLSessionDataTask *task, id responseObject) { NSLog(@"Response: %@", responseObject); } failure:^(NSURLSessionDataTask *task, NSError *error) { NSLog(@"Error: %@", error); }]; 

（对于AFNetworking 1.x和2.x语法，请参阅此答案的修订历史。）
