嗨，我是初学者，英语不是我的母语，所以我为错误道歉。
我在尝试向API发出http请求时遇到以下异常
[ERROR ] SRVE0777E: Exception thrown by application class 'org.springframework.web.servlet.FrameworkServlet.processRequest:973'

方法trowing异常
public Summoner getSummonerInfo(Summoner summoner) {
javax.ws.rs.client.Client client = ClientBuilder.newClient();
WebTarget target = client.target("http://" + summoner.getSummonerRegion()+".api.pvp.net");
String summonerInfo = target.path("api/lol/"+ summoner.getSummonerRegion() +"/v1.4/summoner/by-name/" + summoner.getSummonerName() + "?api_key=11111111111").request().get(String.class);
System.out.println(summonerInfo);
return new Summoner();
}
}
Idk还有什么与某些人有关，以帮助找到解决方案，所以请向我询问你可能需要的任何其他东西
答案 0 :(得分：0)
据我所知，无论你想要获得什么字符串，它都不是字符串。也许您正在使用的API（我没有考虑过）尝试以不可能的方式构造该String。
