Question

我正在使用Spring MVC和Jsoup并编写了Spring Controller，它发送了Jsoup Connection.Response，它来自以下代码：

@RequestMapping(method = RequestMethod.POST, value = "/getPage")
public Connection.Response getJsoupResponsePage(Principal loggedInUser,
                                 HttpServletRequest request,HttpServletResponse response) {

Connection.Response res = Jsoup.connect(url)
                               .data("j_username", "username")
                               .data("j_password", "password")
                               .method(Method.POST).execute();
 return res;
}

我需要在浏览器的新选项卡中打开完整的Connection.Response对象。

我从浏览器调用jquery ajax请求，而url是不同的域名，因此我在向 / getPage 发送请求之前已经打开了该URL的会话。

var ajax_params;
ajax_params = {
            url : "getPage",
            type : "POST",
            cache : false,

            success : function(response) {
                console.log(response);  
            },  error : function() {
                console.log("ERROR");
            }
    }
$.ajax(ajax_params);

我得到406 Not Acceptable并且我在ajax调用中遇到错误。

406 http状态代码为not acceptable。这意味着在您的情况下，对于Could not find acceptable representation对象，spring不能Connection.Response。将其更改为String并返回JSOUP响应的正文。

@RequestMapping(method = RequestMethod.POST, value = "/page")
public @ResponseBody String getJsoupResponsePage(HttpServletRequest request,HttpServletResponse response) throws IOException {

    Connection.Response res = Jsoup.connect("http://abv.bg")
            .data("j_username", "username")
            .data("j_password", "password")
            .method(Connection.Method.POST).execute();
    return res.body();
}

并使用此ajax方法调用它：

var ajax_params = {
            url : "page",
            type : "POST",
            cache : false,
            success : function(response) {
                console.log(response);  
            },  error : function() {
                console.log("ERROR");
            }
    }
$.ajax(ajax_params);

ps：我有点疑惑你想要做什么。只需解决406错误。

需要从Spring MVC Controller返回JSoup Conncetion.Response作为响应
