我有一个运行在http://localhost:7777的React Apollo客户端 还有一个运行在http://localhost:4444
上的Graphql-Yoga服务器当我通过react-apollo执行突变时,它们可以在后端正常工作。
当我通过Firefox执行变异时,(预检请求+发布请求)会记录在Chrome DevTools中。
但是,当我通过Chrome执行突变时,DevTools上只会记录预检请求。
在这两种情况下,突变均按预期发生,我想知道为什么Google chrome无法在其网络标签上显示POST请求。

我已经尝试使用express cors中间件,但是它确实使服务器挂起。
// Graphql Yoga Instantiation function
const { GraphQLServer } = require("graphql-yoga");
const Mutation = require("./resolvers/Mutation");
const Query = require("./resolvers/Query");
const db = require("./db");
function createServer() {
return new GraphQLServer({
typeDefs: "./src/schema.graphql",
resolvers: {
Mutation,
Query
},
resolverValitaionOptions: {
requireResolversForResolveType: false
},
context: req => ({ ...req, db })
});
}
module.exports = createServer;
运行npm run dev
时启动服务器的文件
// Server initialization file index.js
const cookieParser = require("cookie-parser");
require("dotenv").config({ path: "variables.env" });
const createServer = require("./createServer");
const db = require("./db");
const jwt = require("jsonwebtoken");
const server = createServer();
//Use express to handle cookies (JWT)
server.express.use(cookieParser());
//Use express to populate current user
server.express.use((req, res, next) => {
const {
cookies: { token }
} = req;
if (token) {
const { userId } = jwt.verify(token, process.env.APP_SECRET);
req.userId = userId;
}
next();
});
// Populate each request with the user
server.express.use(async (req, res, next) => {
const { userId } = req;
const { query } = db;
if (!userId) return next();
const user = await query.user(
{ where: { id: userId } },
"{id, permissions, email, name}"
);
req.user = user;
return next();
});
server.start({
cors: {
credentials: true,
origin: process.env.FRONTEND_URL // http://localhost:7777
},
deets: deets => {
console.log(`Server is now running on localhost:${deets.port}`);
}
});
我希望在Chrome DevTools网络标签上看到发布请求日志,就像在Firefox上显示的一样。
答案 0 :(得分:0)
似乎是本地问题。
我刚刚改变了
{ message: 'Missing credentials' }
至:
server.start({
port: 4444,
cors: {
credentials: true,
origin: process.env.FRONTEND_URL
},
deets: deets => {
console.log(`Server is now running on localhost:${deets.port}`);
}
});
它在两种情况下都能完美运行。
然后,我改变它回到它仍然工作。
const options = {{
port: 4444,
cors: {
credentials: true,
origin: process.env.FRONTEND_URL
},
deets: deets => {
console.log(`Server is now running on localhost:${deets.port}`);
}
}};
server.start(options);
重要提示:。我之前多次重新启动过graphql服务器,但在将选项提取到const时它无法正常工作。这可能是某种缓存问题吗?
