我正在尝试创建对 REST API 的 POST 请求以发布新的时间条目。post请求所需的XML结构如下：

<time-entry>
  <person-id>#{person-id}</person-id>
  <date>#{date}</date>
  <hours>#{hours}</hours>
  <description>#{description}</description>
</time-entry>

使用 AFNetworking 是否仅通过将参数的 NSDictionary 传递给 POST 请求就在幕后完成 XML 编码？到目前为止，这是我的代码：

从我的 APIClient：

-(void)postTimeEntry:(TLActiveWork *)work {

[self setAuthorizationHeaderWithUsername:[self.activeUser username] 
   password:[self.activeUser password]];

// Most of the following is static data. Just trying to get a successful POST at the 
// moment.
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        [NSString stringWithFormat:@"%@",[[self activeUser] personId]], @"person-id",
                        [NSString stringWithFormat:@"%@",[NSDate date]], @"date",
                        @"1", @"hours",
                        @"testing...!", @"description",
                        nil];

NSDictionary *wrapper = [NSDictionary dictionaryWithObjectsAndKeys:
                         params, @"time-entry",
                         nil];

 NSLog(@"Params: %@", wrapper);

// AFNetworking call!

[self postPath:[NSString stringWithFormat:@"/projects/%@/time_entries.xml",
   [[work project] projectId]] parameters:wrapper 
   success:^(AFHTTPRequestOperation *operation, id responseObject) {

    NSLog(@"-----SUCCESS!!!-----");

} failure:^(__unused AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"failure: %ld - %@", [operation.response statusCode], 
           [error description]);
}];
}

是的。我的 APIClient 操作通过以下方式为 XML 配置：

[self registerHTTPOperationClass:[AFXMLRequestOperation class]];

现在，每次我尝试使用此代码进行 POST 时，我总是会收到 422 响应代码失败，我认为这意味着传递的实体无法处理。https://stackoverflow.com/a/3291292/312411

我认为我的问题只是没有通过 NSDictionary 参数传递正确构建帖子的 XML 吗？

任何帮助将不胜感激！

谢谢。

虽然我的回答不及时，但我希望它可以帮助遇到这个问题的其他人。下面是一个如何XML POST使用AFNetworking. 

AFHTTPClient *HTTPClient = [[AFHTTPClient alloc] initWithBaseURL:@"https://stackoverflow.com"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:HTTPClient.baseURL];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[[NSFileManager defaultManager] contentsAtPath:[[NSBundle mainBundle] pathForResource:@"TheNameOfTheXMLFileToSend" ofType:@"xml"]];

AFHTTPRequestOperation *operation = [HTTPClient HTTPRequestOperationWithRequest:request 
success:^(AFHTTPRequestOperation *operation, id responseObject)
{
     // The server responded without an error.
} 
failure:^(AFHTTPRequestOperation *operation, NSError *error) 
{
    // The server responded with an error.
}];

[HTTPClient enqueueHTTPRequestOperation:operation];
