将自定义标头添加到“请求”

Question

I am proxying my api via following setup in my express config

  // Proxy api calls
  app.use('/api', function (req, res) {
    let url = config.API_HOST + req.url
    req.pipe(request(url)).pipe(res)
  })

config.API_HOST in here resolves to my api url and req.url is some endpoint ie /users I tried following documentation on npm for request and set up my headers like so

  // Proxy api calls
  app.use('/api', function (req, res) {
    let options = {
      url: config.API_HOST + req.url,
      options: { 'mycustomheader': 'test' }
    }
    req.pipe(request(options)).pipe(res)
  })

But I am not able to see my custom headers in chrome dev tools under Network.

Answer 1

Was able to achieve it this way

  app.use('/api', function (req, res) {
    let url = config.API_HOST + req.ur
    req.headers['someHeader'] = 'someValue'
    req.pipe(request(url)).pipe(res)
  })

Answer 2

for some weird reasons req.setHeader('someHeader', 'somValue') didn't work for me.

but req.headers['someHeader'] = 'someValue' this worked
