Question

我有一个dropwizard服务器和一个使用react和redux的通用应用程序。当我尝试使用通用应用程序中的axios进行后期调用时。我收到net :: ERR_CONNECTION_RESET错误。

我在dropwizard中设置了CORS：

    FilterRegistration.Dynamic filter = environment.servlets().addFilter("CORS",CrossOriginFilter.class);
    filter.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), true, "/*");
    filter.setInitParameter(CrossOriginFilter.ALLOWED_METHODS_PARAM, "GET,PUT,POST,DELETE,OPTIONS");
    filter.setInitParameter(CrossOriginFilter.ALLOWED_ORIGINS_PARAM, "*");
    filter.setInitParameter(CrossOriginFilter.ACCESS_CONTROL_ALLOW_ORIGIN_HEADER, "*");
    filter.setInitParameter(CrossOriginFilter.ALLOWED_HEADERS_PARAM, "*");

我有来自jetty的以下调试日志： DEBUG [2016-03-07 05:42:04,189] org.eclipse.jetty.servlets.CrossOriginFilter: Cross-origin filter configuration: allowedOrigins = *, allowedMethods = GET,PUT,POST,DELETE,OPTIONS, allowedHeaders = *, preflightMaxAge = 1800, allowCredentials = true,exposedHeaders = ,chainPreflight = true

来自axios的请求是这样的

request
            .post('http://localhost:8080/auth/register',{
                 username: 'foo',
                 password: 'bar'
             })
            .then((res) => {
                console.log(res);
            })
            .catch((err) => console.log(err))

如果我从控制台使用简单的XmlHTTPRequest

，它也可以工作

 var xhttp = new XMLHttpRequest();
  xhttp.onreadystatechange = function() {
    if (xhttp.readyState == 4 && xhttp.status == 200) {
      console.log("OK");
    }
  };
  xhttp.open("POST", "http://localhost:8080/auth/register", true);
  xhttp.send(JSON.stringify({
           username: 'foo',
           password: 'bar
        }));

从Dropwizard服务器请求时axios中的net :: ERR_CONNECTION_RESET
