如何从Node.js/Express服务器调用GraphQL API? [英] How to call GraphQL API from Node.js/Express server?

问题描述

我最近为我的Express服务器实现了一个架构和一些解析器.我通过/graphql 成功地测试了它们，现在我想调用从REST API访问时实现的查询，如下所示:

I recently implemented a schema and some resolvers for my Express server. I tested them successfully through /graphql and now I would like to call the queries I implemented when accessing from a REST API, like so:

//[...]
//schema and root correctly implemented and working
app.use('/graphql', graphqlHTTP({
  schema: schema,
  rootValue: root,
  graphiql: true,
}));

//I start the server
app.listen(port, () => {
  console.log('We are live on ' + port);
});

//one of many GET handlers
app.get("/mdc/all/:param", function(req, res) {
    //call one of the (parametrized) queries here
    //respond with the JSON result
});

如何在GET处理程序中调用用GraphQL定义的查询?如何将参数传递给他们?

How can I call the queries I defined with GraphQL inside my GET handlers? How do I pass parameters to them?

谢谢！

推荐答案

我使用Apollo，并通过POST从前端直接在/graphql 上执行查询.

I used Apollo and performed queries directly on /graphql through POST from the front-end.
