Question

每次尝试发布时，我都会收到无法获取/ api / auth / signup的错误，我无法弄清楚为什么有人可以帮助我吗？非常感谢，我不明白我想在节点js中发布寄存器的过程，但是它总是告诉我无法获取/ api / auth / signup

auth.js

import axios from "axios";

const API_URL = "http://localhost:8080/api/auth/";

class AuthService {
  async login(username, password) {
    console.log(username, password);
    return axios
      .post(API_URL + "signin", {
        username,
        password,
      })
      .then((response) => {
        if (response.data.accessToken) {
          localStorage.setItem("user", JSON.stringify(response.data));
        }

        return response.data;
      });
  }

  async logout() {
    localStorage.removeItem("user");
  }

  async register(username, email, password) {
    return axios.post(API_URL + "signup", {
      username,
      email,
      password,
    });
  }

  getCurrentUser() {
    return JSON.parse(localStorage.getItem("user"));
  }
}



     export default new AuthService();

server.js


const express = require("express");
const bodyParser = require("body-parser");
const cors = require("cors");

const app = express();

var corsOptions = {
  origin: "http://localhost:8080",
};

app.use(cors(corsOptions));


app.use(bodyParser.json());


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

// simple route
app.get("/", (req, res) => {
  res.json({ message: "it works." });
});

// set port, listen for requests
const PORT = process.env.PORT || 8080;
app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}.`);
});

Answer 1

似乎您正在尝试过帐到不存在的路由。您需要构建/api/auth/signup路由，以便从axios向其发送请求。

// simple example of post route
app.post("/api/auth/signup", (req, res) => {
  const { username, email, password } = req.body;
  // Your logic to register user in your database

  // Send response after database interaction
  res.status(201).json({ message: 'User signed up for service' })
});

Answer 2

对于每个特定路由，您需要在应用程序中实现相应的路由。在您的应用程序中，如果您需要访问两个不同URL的发布请求，则需要处理两个发布路由。

For`/api/auth/signin`

app.post('/api/auth/signin', (req, res)=>{
//Your Implementation here
res.status(201).json({message: 'Your Message'})
})

For`/api/auth/signup`

app.post('/api/auth/signup', (req, res)=>{
//Your Implementation here
res.status(201).json({message: 'Your Message'})
})

无法使用axios在Node JS中获取发布请求
