apollo-server-express CORS issue

由 大兔子大兔子 提交于 2019-12-31 01:01:28
问题 So I am migrating to apollo-server-express 2.3.3 ( I was using 1.3.6 ) I've followed several guides, making the necessary tweaks but am stuck in a CORS issue. According to the docs you have to use the applyMiddleware function to wire up the apollo server with express. I am currently doing the following: const app = express(); // CORS configuration const corsOptions = { origin: 'http://localhost:3000', credentials: true } app.use(cors(corsOptions)) // Setup JWT authentication middleware app

问题 I have a strange problem and cannot figure out what the problem is. The Error-message doesn't help.

问题 I am having a real hard time standing up bidirectional data transfer from a html page to my node.js application and then back to the html page. I'm pretty sure I'm all over the correct solution, but I'm just not getting it to work. I'm using the following for my node.js application: var express = require('/usr/lib/node_modules/express'); var app = express(); app.use(function(err, req, res, next){ console.error(err.stack); res.send(500, 'Something broke!'); }); app.use(express.bodyParser());

proxy json requests with node express

由 纵饮孤独 提交于 2019-12-30 09:46:10
问题 I use the following node-express code to proxy requests from a web server to an API server: app.use('/api', function(req, res) { var url = 'http://my.domain.com/api' + req.url; req.pipe(request(url)).pipe(res); }); This works well for simple requests of any verb (get, post, etc...), however once I send 'Content-type': 'application/json' requests, it hangs on the pipe line. Why does this simple node-express proxy code hang on json requests? How can it be altered to support them? 回答1: You need
