从 ClientResource 检索响应正文
Retrieve response body from ClientResource
我尝试使用 ClientResource 发出 POST 请求,我能够检索响应 STATUS,我也想得到异常时的response body
这是我的代码:
public static Pair<Status, JSONObject> post(String url, JSONObject body) {
ClientResource clientResource = new ClientResource(url);
try {
Representation response = clientResource.post(new JsonRepresentation(body), MediaType.APPLICATION_JSON);
String responseBody = response.getText();
Status responseStatus = clientResource.getStatus();
return new ImmutablePair<>(responseStatus, new JSONObject(responseBody));
} catch (ResourceException e) {
logger.error("failed to issue a POST request. responseStatus=" + clientResource.getStatus().toString(), e);
//TODO - how do I get here the body of the response???
} catch (IOException |JSONException e) {
throw e;
} finally {
clientResource.release();
}
}
这是我的服务器资源 returns 失败时
的代码
getResponse().setStatus(Status.CLIENT_ERROR_FORBIDDEN);
JsonRepresentation response = new JsonRepresentation( (new JSONObject()).
put("result", "failed to execute") );
return response;
我尝试抓住 "result" 但没有成功
其实getResponseEntity
方法returns响应的内容。它对应于一个表示。如果你希望有一些 JSON 内容,你可以用 JsonRepresentation
class 包装它:
try {
(...)
} catch(ResourceException ex) {
Representation responseRepresentation
= clientResource.getResponseEntity();
JsonRepresentation jsonRepr
= new JsonRepresentation(responseRepresentation);
JSONObject errors = jsonRepr.getJsonObject();
}
您可以注意到 Restlet 还支持带注释的异常。
否则我写了一篇关于这个主题的博客post:http://restlet.com/blog/2015/12/21/exception-handling-with-restlet-framework/。我认为它可以帮助你。
