GraphQL + React-> Express PROXY（网关）中间件

Question

So I've been trying to use GraphQL, React and Express(CORS issues) together. I have an API in another URL. So basically what I want to do is;

• I will send API request to Express,
• Express should redirect my GraphQL Query to the API Address.

First one is okay, right now I am sending API requests to Express. But it isn't sending my GraphQL URL to another URL.

This is my code so far;

 app.use('/api', function (req, res) {
  res.header("Access-Control-Allow-Origin", "http://localhost:8081");
  // restrict it to the required domain
  res.header("Access-Control-Allow-Methods", "GET,PUT,POST,DELETE,OPTIONS");
  // Set custom headers for CORS
  res.header("Access-Control-Allow-Headers", "Content-type,Accept,X-Custom-Header");
  if (req.method == "OPTIONS") {
    res.status(200);
    res.send();
  } else {
    const response = fetch('http://sssss.elasticbeanstalk.com/graphql', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: req,
    }).then(resp =>  res.send(CircularJSON.stringify(req)))
      .catch(error => res.send(error));
  }

Do I have to create a GraphQL server in Express too?

Answer 1

you can use something like this method for fetching in express

app.get('/api', (req , res ) =>{
      let user = {
        userData: req.body,
    }
    res.send(JSON.stringify(user));
    console.log(user.username)

    })
