java - com.sun.jersey.api.client.ClientHandlerException : java. io.IOException:过早的 EOF

Question

我正在使用 jersey api 客户端调用基于 REST 的网络服务(该服务托管在我的本地主机中)。当我打电话时

String entity = (client response object here).getEntity(String.class);

我遇到以下异常:

从您的服务器中可以清楚地看出，响应中的 Content-Length header 存在问题。它不包含 Content-Length header 。您应该将其添加到具有正确值的响应中。
