How to post an array of objects with Chai Http

问题:

I'm trying to post an array of object with ChaiHttp like this:

agent.post('route/to/api')
  .send( locations: [{lat: lat1, lon: lon1}, {lat: lat2, lon: lon2}])
  .end (err, res) -> console.log err, res

It returns an error as below:

 TypeError: first argument must be a string or Buffer
at ClientRequest.OutgoingMessage.end (_http_outgoing.js:524:11)
at Test.Request.end (node_modules/superagent/lib/node/index.js:1020:9)
at node_modules/chai-http/lib/request.js:251:12
at Test.then (node_modules/chai-http/lib/request.js:250:21)

events.js:141 throw er; // Unhandled 'error' event ^

Error: incorrect header check at Zlib._handle.onerror (zlib.js:363:17)

I also tried to post like this, as we do with postman:

agent.post('route/to/api')
  .field( 'locations[0].lat', xxx)
  .field( 'locations[0].lan', xxx)
  .field( 'locations[1].lat', xxx)
  .field( 'locations[2].lat', xxx)
  .then (res) -> console.log res

but payload.locations is received as an undefined.

Any idea how to post an array of objects via chai-http?

EDIT:

Here is my route and I think there's something wrong with stream payload:

method: 'POST'
path:
config:
  handler: my_handler
  payload:
    output: 'stream'

回答1:

I had the same problme here. It seems that simply the chai-http documentation is wrong. It sais:

// Send some Form Data
chai.request(app)
 .post('/user/me')
 .field('_method', 'put')
 .field('password', '123')
 .field('confirmPassword', '123')

Which does NOT work. This worked for me:

chai.request(app)
  .post('/create')
  .send({ 
      title: 'Dummy title',
      description: 'Dummy description'
  })
  .end(function(err, res) { ... }

回答2:

Try to use .send({locations: [{lat: lat1, lon: lon1}, {lat: lat2, lon: lon2}]}). Because .field('a', 'b') not working.

1. body as a form data

   .put('/path/endpoint')
   .type('form')
   .send({foo: 'bar'})
   // .field('foo' , 'bar')
   .end(function(err, res) {}
   
   // headers received, set by the plugin apparently
   'accept-encoding': 'gzip, deflate',
   'user-agent': 'node-superagent/2.3.0',
   'content-type': 'application/x-www-form-urlencoded',
   'content-length': '127',
   

2. body as application/json

   .put('/path/endpoint')
   .set('content-type', 'application/json')
   .send({foo: 'bar'})
   // .field('foo' , 'bar')
   .end(function(err, res) {}
   
   // headers received, set by the plugin apparently
   'accept-encoding': 'gzip, deflate',
   'user-agent': 'node-superagent/2.3.0',
   'content-type': 'application/json',
   'content-length': '105',
