如何在不使用AFMultipartFormData的情况下使用AFNetworking 3发送NSData

Question

我正试图通过AFNetworking 3将wav文件作为NSData发送到rest服务。我想好了如何使用AFMultipartFromData发送，但我遇到了这样的错误errorMessage = "Can Not Map Content-Type String multipart/form-data; boundary=Boundary+02588C5 To Media Type ";

当我和创建rest服务的人交谈时，他告诉我我必须只发送NSData，而不是像AFMultipartFormData那样的数据。我在这里需要一些帮助，因为我找不到任何发送"仅"NSData的方法。我的代码如下；

    NSURL *URL = [NSURL URLWithString:@"http://xxxMyService"];
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
configuration.HTTPAdditionalHeaders = @{@"xx": @"yy ; zz"};
AFHTTPSessionManager *manager2 = [[AFHTTPSessionManager alloc] initWithBaseURL:URL sessionConfiguration:configuration];
manager2.responseSerializer = [AFJSONResponseSerializer serializer];
//I converted wav file to NSData
NSData *data=[self setVoiceRecordToNSData];

[manager2 POST:@"http://xxxMyService" parameters:nil
 constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{  
[formData appendPartWithFileData:data name:@"data" fileName:@"Path.wav" mimeType:@"audio/wav"];
}  
progress:nil success:^(NSURLSessionTask *task, id responseObject 
{ NSLog(@"JSON: %@", responseObject);} 
failure:^(NSURLSessionTask *operation, NSError *error) {
         NSLog(@"Error: %@", error); }];

尝试在POST 之前添加此代码

manager2.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"multipart/form-data"];
