RESTKit 2.0: AFHTTPClient with text/html

我正在使用RESTKit v0.20.3。由于我不期待响应对象，我决定使用 AFHTTPClient 来 POST。我有以下代码：

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
httpClient.parameterEncoding = AFJSONParameterEncoding;
[httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];
[httpClient setDefaultHeader:@"Accept" value:@"application/json"];
[httpClient postPath:@"/update" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
   NSLog(@"AFJSONRequestOperation Alt response MIMEType %@",[responseObject MIMEType]);
    [self.navigationController dismissViewControllerAnimated:YES completion:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"***ERROR*****: %@", [error localizedDescription]);
}];

这是我的日志

我收到错误是在接收text/html，但我如何告诉AFHTTPClient期望text/html？

我尝试添加：

[AFJSONRequestOperation addAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];

2014-04-01 16:48:13.110 App[13289:60b] ***ERROR*****: The operation couldn’t be completed. (Cocoa error 3840.)

如果我使用 AFHTTPRequestOperation ，如何将参数传递给它？我正在使用RESTKit，所以我不能使用AFNetworking 2.0。代码示例将不胜感激！

如果你检查HTML的内容，它实际上说：

<h1>Not Found</h1><h2>404</h2>

因此，问题不在于您请求的页面不存在，而在于返回的内容类型是错误的。

验证您正在使用的 URL 和路径。
