Axios 发布空请求

问题描述

我正在尝试向后端发送一个 axios 请求，但它最终有一个空的 body，我不明白它为什么这样做.这是请求的代码:

I am trying to send an axios request to the backend, but it ends up having an empty body, and i do not understand why it does that.This is the code for the request:

axios.post('/register', {email: email, password: password, username: username, company: company}).then(response => {
    console.log(response.data);
});

这是后端的代码:

authRouter.post('/register', (request, response) => {
    console.log(request.body);

});

这个输出一个空的request.body.我还检查了发送的 JSON，它根本不是空的.有没有办法在发送之前查看请求的形式?这个 authRouter 是一个 module.export，它被主要的 app 模块使用.这个 app 模块有这样的配置:

And this one outputs an empty request.body. I've also checked the JSON sent, and it is not empty at all. Is there a way to see what is the form of the request before being sent?This authRouter is a module.export, that is being used by the main app module. This app module has this configuration:

app.use(express.static("public"));
app.use(session({ secret: "shh", resave: false, saveUninitialized: false }));
app.use(bodyParser.urlencoded({ extended: false }));
app.use(passport.initialize());
app.use(passport.session());

app.set('views', __dirname + '/views');
app.set('view engine', 'pug');

app.use(authRouter);

https.createServer({key: fs.readFileSync('ssl/key.pem'), cert: fs.readFileSync('ssl/cert.pem')}, app).listen(8080);

推荐答案

问题来自于 body-parser 想要一个 x-www-form-urlencoded请求，我没有提供.

The issue came from the fact that body-parser wants an x-www-form-urlencoded request, and I wasn't providing one.

我已经为它设置了 axios 请求的头部，代码如下所示:

I've set the header for the axios request to it, and the code looks like this:

axios.post('/register', {
  email: email,
  password: password,
  username: username,
  company: company
}, {
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded'
  }
})
  .then(response => {
    console.log(response.data);
  });
