Question

这是我的Strifified json，

 {
       "Request":{
              "Object1":{
                 "Key1":"Value1"
              },
              "Object2":{
                  "Key2":"Value2"
              }
       },
       "Object3":{
                 "Key3":"Value3"
       }
}

我正在使用Gson形成这个。 String Stringifiedjson = new Gson().toJson(user); 这是我想要实现的目标。

RestTemplate rest = new RestTemplate();
String url = "";
String event = rest.getForObject(url, Stringifiedjson);

如何发送到我的REST服务并在onEventHandler或onErrorHandler中取回我的结果。我基本上来自JavaScript背景。
为什么方法getForObject不接受String, String为params。

更新

AuthenticateUser user = new AuthenticateUser(credential, Header);       
HttpHeaders requestHeaders = new HttpHeaders();
requestHeaders.setContentType(new MediaType("application","json"));         
//HttpEntity<AuthenticateUser> requestEntity = new HttpEntity<AuthenticateUser>(user, requestHeaders);


RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJacksonHttpMessageConverter());
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());
String url = "url";             
String result = restTemplate.postForObject(url, AuthenticateUser.class, String.class);

附件是我得到的例外情况。

关于第二个问题：我刚刚找到了这个例子（你可以看看整个文档;））

2.7.1 Basic Usage Example The following example shows a query to google for the search term "SpringSource".

String url = "https://ajax.googleapis.com/ajax/services/search/web?v=1.0&q={query}";

// Create a new RestTemplate instance
RestTemplate restTemplate = new RestTemplate();

// Add the String message converter
restTemplate.getMessageConverters().add(new StringHttpMessageConverter());

// Make the HTTP GET request, marshaling the response to a String
String result = restTemplate.getForObject(url, String.class, "SpringSource");

getForObject

public <T> T getForObject(URI url,
                    Class<T> responseType)
          throws RestClientException
Description copied from interface: RestOperations
Retrieve a representation by doing a GET on the URL . The response (if any) is converted and returned.
Specified by:
getForObject in interface RestOperations
Parameters:
url - the URL
responseType - the type of the return value
Returns:
the converted object
Throws:
RestClientException

您的堆栈跟踪中的异常可能与此post的相同问题有关。当您的应用尝试在主线程中建立连接时，会出现此问题。

在应用程序主ui线程中执行任何网络操作时抛出NetworkOnMainThreadException（另请参阅Keeping Your App Responsive。这是不允许的。您将不得不使用后台线程进行网络操作，请参阅http://developer.android.com/guide/components/processes-and-threads.html
