Question

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

    [formData appendPartWithFileData:data name:@"post_media" fileName:imageName mimeType:@"image/jpeg"];

    [formData appendPartWithFormData:[[requestDict objectForKey:@"user_statusmessage"] dataUsingEncoding:NSUTF8StringEncoding] name:@"user_statusmessage"];

    [formData appendPartWithFormData:[[requestDict objectForKey:@"user_description"] dataUsingEncoding:NSUTF8StringEncoding] name:@"user_description"];

    [formData appendPartWithFormData:[[requestDict objectForKey:@"id"] dataUsingEncoding:NSUTF8StringEncoding]   name:@"id"];


    [request addValue:self.header forHTTPHeaderField: @"X-API-KEY"];

    [request addValue:@"application/json" forHTTPHeaderField: @"Content-Type"];

} error:nil];

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

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"%@ %@", response, responseObject);
    }
}];

[uploadTask resume];

，错误是

Answer 1

在 AFHTTPClient 示例中，您将默认编码设置为AFJSONParameterEncoding，默认情况下AFHTTPRequestOperationManager使用 AFHTTPRequestSerializer ，因此您需要设置 requestSerializer 。< / p>

manager.requestSerializer = [AFJSONRequestSerializer serializer];

Answer 2

错误说明了一切：你从服务器得到400响应，这意味着你发送的内容要么格式不正确，要么服务器无法理解。请参阅以下可能对您有所帮助的链接：
