java - 无法发布到黑板构建 block

Question

我有一个使用 Spring MVC 的构建 block 。

Controller 看起来像这样:

@RequestMapping(value = "/addUpdateUser",method = {RequestMethod.GET, RequestMethod.POST})  
@ResponseBody
public String getAddUpdateUser(HttpServletRequest request) {
    String xml = request.getParameter("xml");
....

当我从我的应用程序中调用它时，如下所示:

    URI url = new URI(baseUrl+"/users/addUpdateUser");
    HttpClient httpclient = HttpClients.createDefault();
    HttpPost httppost = new HttpPost(url);
    HttpResponse response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();

它失败了......我得到一个网页，说我无权访问该页面，但是如果我将代码更改为这样的 HttpGet:

    URI url = new URI(baseUrl+"/users/addUpdateUser");
    HttpClient httpclient = HttpClients.createDefault();
    HttpGet httpget = new HttpGet(url);
    HttpResponse response = httpclient.execute(httpget);
    HttpEntity entity = response.getEntity();

效果很好......

为什么我无法对黑板 Buildingblock 执行 POST 操作？

Blackboard Learn 默认情况下会阻止外部帖子。

您需要在 @RequestMapping 上方添加 @NoXSRF 注释，这样您就可以访问它。
