Question

不确定发生了什么，但是当我在POST请求中到达我的控制器时，req.body参数没有显示出来。

我已经关闭了middleware.json中的csrf：

{
    "middleware": {
        "errorPages": {
            "404": "errors/404",
            "500": "errors/500",
            "503": "errors/503"
        },

        "session": {
            "module": "connect-redis",
            "config": {
                "ttl": 3600
            },
            "secret": "<some secret>"
        },
        "appsec": {
            "csrf": false,
            "csp": false,
            "p3p": false,
            "xframe": "SAMEORIGIN"
        }
//
//      "compiler": {
//          "dust": "templates",
//          "less": "css"
//      },
//


//      "static": {
//          "srcRoot": "path:./public",
//          "rootPath": "path:./.build"
//      }
    }
}

控制器代码：

app.post('/user', function (req, res) {
        res.format({
            json: function () {
                //extract the user from the req
                try {
                    var user = new User();
                    user.firstName = req.body.firstName;
                    user.lastName = req.body.lastName;
                    user.userName = req.body.userName;
                    user.password = req.body.password;
                    user.email = req.body.email;

                    //subsequent code omitted...
                } catch (err) {
                    //handle error
                }
            }
        })
    });

POST请求如下所示：

POST / user HTTP / 1.1 Host：localhost：8000 Cache-Control：no-cache

{“firstName”：“John”，“lastName”：“Doe”，“userName”：“jdoe”，   “password”：“somepassword”，“email”：“jdoe@jdoe.com”}

Answer 1

您必须将此实例中的标头设置为Content-Type application / json

POST /user HTTP/1.1
Host: localhost:8000
Content-Type: application/json
Cache-Control: no-cache

{ "firstName":"John", "lastName" : "Doe", "userName": "jdoe", "password" : "somepassword", "email": "jdoe@jdoe.com" }

Answer 2

binarygiant说的是什么。如果您无法在请求中设置标题，则可以在发布之前始终序列化JSON。
