Question

body-parser的中间件问题：数据被存储为一个对象，该对象随后调用/ api / new来发布到SQL数据库中。

查询本身没有问题，但数据库中的数据为空值。

我的想法：

app.use（express.urlencoded（{ 扩展：true }））; 设置为true，因为某些值为INT，
我尝试过JSON.Stringify数据，然后将其发送到POST请求。没用
还玩着标题

// const config = { //标头：{ //接受：“ application / json”， //“ accept-language”：“ en_US”， //“ content-type”：“ application / x-www-form-urlencoded” //} //};

axios.post（“ / api / new”，{newEntry}，配置...

我认为问题可能是由于它的router.post位于我的api路由中而不是app.post

```
     var newEntry = {
          First_Name: FirstName.toUpperCase(),
          Last_Name: LastName.toUpperCase(),
          Employ_ID: parseInt(EmployID),
          Problem: checkedValue,
          PhoneNumber: phoneNumber,
          Provider: domain
        };
        var stringNewEntry = JSON.stringify(newEntry);

        console.log("Right before Post");
        console.log(newEntry);

        axios
          .post(
            "/api/new",
           {newEntry},
            {
              timeout: 10000
            }
          )
          .catch(error => {
            if (error.code === "ECONNABORTED") return "timeout";
          })
          .then(res => {
            console.log(newEntry);
            if (res === "timeout") {
              console.log("Please Try Again");
            } else {
              console.log("SUCCESS!");
            }
          });
      }

服务器文件

    const express = require("express");
    const app = express();
    var bodyParser = require('body-parser')

    const PORT = process.env.PORT || 3001;
    var routes = require("./routes/api-routes");
    // Define middleware here

    app.use(express.json());
    app.use(bodyParser.json());
    app.use(express.urlencoded({
      extended: true
    }));

    // Serve up static assets (usually on heroku)
    if (process.env.NODE_ENV === "production") {
      app.use(express.static("client/build"));
    }
    // Add routes, both API and view
    app.use(routes);

    // Start the API server
    app.listen(PORT, function() {
      console.log(`  ==> API Server now listening on PORT ${PORT}!`);
    });

api路由


    router.route("/api/new").post(function(req, res) {
  console.log("Data:");

  console.log(req.body.First_Name);

  var dbQuery =
    "INSERT INTO KioskInfo (First_Name,Last_name,Employ_ID,Problem,PhoneNumber,Provider) VALUES (?,?,?,?,?,?)";
  var dbQueryPermanent =
    "INSERT INTO KioskData (First_Name,Last_name,Employ_ID,Problem) VALUES (?,?,?,?)";
  var IgnoreQuery =
    "INSERT IGNORE INTO KioskInfo (First_Name,Last_name,Employ_ID,Problem,PhoneNumber,Provider) VALUES (?,?,?,?,?,?)";

  connection.query(
    dbQuery,
    [
      req.body.First_Name,
      req.body.Last_Name,
      req.body.Employ_ID,
      req.body.Problem,
      req.body.PhoneNumber,
      req.body.Provider
    ],
    function(err, result) {
      if (err) {
        connection.query(
          IgnoreQuery,
          [
            req.body.First_Name,
            req.body.Last_Name,
            req.body.Employ_ID,
            req.body.Problem,
            req.body.PhoneNumber,
            req.body.Provider
          ],
          function(IgnErr, IgnResult) {
            if (IgnErr) {
              throw IgnErr;
            } else {
              console.log("Duplicate Entry Ignored");
            }
          }
        );
      }
      //Learn to specify DUP ERR;
      console.log("Successfully Saved Into KioskInfo");
    }
  );

  connection.query(
    dbQueryPermanent,
    [
      req.body.First_Name,
      req.body.Last_Name,
      req.body.Employ_ID,
      req.body.Problem
    ],
    function(err, result) {
      if (err) throw err;
      console.log("Successfully Saved Into KioskData");
      res.end();
    }
  );
});
