我正在发出一个 HTTP 获取请求，它给了我一个 JSON 响应：
{ time : 1345111524000
sub : Test vote
msg :
remain : 420
cur_time : 1345113672856
ver : 1.2.2
p_type : 0
.....
我正在使用适用于 Java 的 Google HTTP 客户端库
我的实现
static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();
static final JsonFactory JSON_FACTORY = new JacksonFactory();
public static class PollInfo{
@Key("time")
public String time;
@Key("sub")
public String sub;
@Key("msg")
public String msg;
.
.
}
public static class PollInfoUrl extends GenericUrl{
public PollInfoUrl(String encodedUrl) {
super(encodedUrl);
}
}
public PollInfo getPollInfo() throws Exception{
HttpRequestFactory requestFactory =HTTP_TRANSPORT.createRequestFactory(
new HttpRequestInitializer() {
@Override
public void initialize(HttpRequest request) {
request.setParser(new JsonObjectParser(JSON_FACTORY));
}
});
PollInfoUrl url = new PollInfoUrl("http://**IP**:8000/web1/num1?cmd=en_poll_info&src=src_web&ver=default&deviceToken=DUMMYDEVICETOKEN&ref_id=83f2491d-0b0c-4d1c-8a14-053256cf157a&p_type=0&p_creator=Wp&eid=3&sender=Wp";);
HttpRequest request = requestFactory.buildGetRequest(url);
PollInfo pollInfo = request.execute().parseAs(PollInfo.class);
return pollInfo;
}//getPollInfo();
我能够解析我的项目中的其他 URL，但对于这种特殊情况，它给了我例外，我需要一些指导来修复它。以下是我的服务器异常日志
