[英]Android: Checking HTTP response code: getting 200; should be 302
[英]REST Webservice - Sample Code - Gives HTTP 302 response
我只是在嘗試REST Web服務; 標准樣品; 雖然我可以創建war並將其加載到WSO2 AS中,但是當我嘗試將其與客戶端連接時,會收到HTTP 302的響應; 我想知道錯誤可能在哪里; 以下是我的文件列表。
package com.indu.rs.test;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
// POJO, no interface no extends
// The class registers its methods for the HTTP GET request using the @GET annotation.
// Using the @Produces annotation, it defines that it can deliver several MIME types,
// text, XML and HTML.
// The browser requests per default the HTML MIME type.
//Sets the path to base URL + /hello
@Path("/hello")
public class Hello {
// This method is called if TEXT_PLAIN is request
@GET
@Produces(MediaType.TEXT_PLAIN)
public String sayPlainTextHello() {
return "Hello Jersey";
}
// This method is called if XML is request
@GET
@Produces(MediaType.TEXT_XML)
public String sayXMLHello() {
return "<?xml version=\"1.0\"?>" + "<hello> Hello Jersey" + "</hello>";
}
// This method is called if HTML is request
@GET
@Produces(MediaType.TEXT_HTML)
public String sayHtmlHello() {
return "<html> " + "<title>" + "Hello Jersey" + "</title>"
+ "<body><h1>" + "Hello Jersey" + "</h1></body>" + "</html> ";
}
} // class

302表示您正在重定向。 使用curl --verbose連接到端點,並查看Location:標頭。 它應該為您提供有關發生情況的線索。
好的,這是我終於從我的一個朋友那里得到的解決方案。
在web.xml中更改/ rest-> / rest / *
創建war文件並上傳到服務器(在我的情況下是WSO2); 服務器上載war文件時,它會使用上下文創建文件(在我的情況下為RSTest)
最后轉到瀏覽器類型:
http://localhost:9100/RSTest/rest/hello
您將看到成功的結果(在本例中為Hello Jersey)
