AFNetworking 3.0多部分请求

问题描述：

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; 
    manager.requestSerializer = [AFJSONRequestSerializer serializer]; 
    manager.responseSerializer = [AFJSONResponseSerializer serializer]; 
    [manager.requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@", [[NSUserDefaults standardUserDefaults] objectForKey:TOKEN]] forHTTPHeaderField:@"Authorization"]; 
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 
    [manager POST:@"http:xxxxx" parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
     [formData appendPartWithFileData:profileImage name:@"file" fileName:@"profileImage.jpg" mimeType:@"image/jpeg"]; 
    } success:^(NSURLSessionTask *task, id responseObject) { 
     completionHandler(responseObject); 
    } failure:^(NSURLSessionTask *operation, NSError *error) { 
     NSData *errorData = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey]; 
     NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData: errorData options:kNilOptions error:nil]; 
     errorHandler(serializedData); 
    }];

此方法工作正常，但不推荐使用constructingBodyWithBlock。我如何优化代码以符合AFNetworking 3.0标准？AFNetworking 3.0多部分请求

答

使用POST:parameters:constructingBodyWithBlock:progress:success:failure:引用（如果不需要它，则为progress提供nil）。

您不需要设置Accept和Content-Type标题类型。这些分别由AFJSONResponseSerializer和AFJSONRequestSerializer设置。

@ios开发人员，您可以使用AFNetworking + UIImageView中的AFNetworking方法setImageWithUrl – Stefan
