客户方面,这就是我发生的事情:
function saveGrades() {
$.post("/savegrades", {classIndex: "classIndexId"}); }
服务器端:
router.post('/savegrades', stormpath.loginRequired, function(req, res) {
console.log("Class index: " + req.body.classIndex);
console.log(req.body);
res.send(200);
});
我的bodyParser
设置如下:
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
无论我尝试过什么,req.body
都是空的,没有classIndex
。我做错了什么?为什么数据没有发布到服务器?
编辑:对于链接的问题,我在这里已经完成了几乎所有相关的答案,但无法找到解决方案。似乎数据永远不会被发送到服务器。当我用调试器检查时,正文总是空的。

请检查代码,
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
之前实施得很好,
router.post('/savegrades',
根据您的评论,
您可以尝试添加Trying在客户端添加mime类型(内容类型)。

尝试此操作并通过 POSTMEN 发送数据以验证数据是否实际发送然后通过函数发送
