Question

我正在尝试从api返回一些数据，但是当我点击服务器时，我收到一条错误的请求消息。我认为问题在于我的JSON Stringify，我是否正确地使用了这个函数来连接我的请求体？

输出：

{ request: 
   { passengers: { kind: 'qpxexpress#passengerCounts', adultCount: 1 },
     slice: [ [Object] ],
     saleCountry: 'GB',
     ticketingCountry: 'GB',
     solutions: 10 } }
Upload successful!  Server responded with: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "badRequest",
    "message": "Invalid inputs: received empty request."
   }
  ],
  "code": 400,
  "message": "Invalid inputs: received empty request."
 }
}

代码：

var express = require('express')
var router = express.Router()
var request = require('request')

/* GET home page. */
router.get('/', function(req, res, next) {
  res.render('index', { title: 'Express' })
})

let flightRequest = {
  "request": {
      "passengers": {
        "kind": "qpxexpress#passengerCounts",
        "adultCount": 1
      },
      "slice": [{
        "kind": "qpxexpress#sliceInput",
        "origin": "LHR",
        "destination": "OSL",
        "date": "2016-12-03",
        "permittedDepartureTime": {
          "kind": "qpxexpress#timeOfDayRange",
          "earliestTime": "06:00",
          "latestTime": "11:00"
        }}],
      "saleCountry": "GB",
      "ticketingCountry": "GB",
      "solutions": 10
    }
  }

console.log(JSON.stringify("hello" + flightRequest))

JSON.stringify(flightRequest)
console.log(flightRequest)

request.post({url:'https://www.googleapis.com/qpxExpress/v1/trips/search?key=XXXXXXXXXXXXXXXXXXXXXXXX', flightRequest: flightRequest}, function optionalCallback(err, httpResponse, body) {
  if (err) {
    return console.error('upload failed:', err);
  }
  console.log('Upload successful!  Server responded with:', body);
});

module.exports = router

Answer 1

我认为您需要按如下方式发布请求

request({
    url: 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=XXXXXXXXXXXXXXXXXXXXXXXX',
    method: "POST",
    json: JSON.stringify(flightRequest)
}, function optionalCallback(err, httpResponse, body) { ...

或者可能是

request.post({
    url: 'https://www.googleapis.com/qpxExpress/v1/trips/search?key=XXXXXXXXXXXXXXXXXXXXXXXX',
    json: JSON.stringify(flightRequest)
}, ...

我是否正确使用此功能来连接我的请求体？

此代码

let flightRequest = 
{
  "request": {
    "passengers": {
      "kind": "qpxexpress#passengerCounts",
      "adultCount": 1
    },
    "slice": [
      {
        "kind": "qpxexpress#sliceInput",
        "origin": "LHR",
        "destination": "OSL",
        "date": "2016-12-03",
        "permittedDepartureTime": {
          "kind": "qpxexpress#timeOfDayRange",
          "earliestTime": "06:00",
          "latestTime": "11:00"
        }
      }
    ],
    "saleCountry": "GB",
    "ticketingCountry": "GB",
    "solutions": 10
  }
}
let flightAppend = {"appended text":"hello"}
var obj = Object.assign(flightAppend, flightRequest)
console.log(JSON.stringify(obj))

生成此输出

{
  "appended text": "hello",
  "request": {
    "passengers": {
      "kind": "qpxexpress#passengerCounts",
      "adultCount": 1
    },
    "slice": [
      {
        "kind": "qpxexpress#sliceInput",
        "origin": "LHR",
        "destination": "OSL",
        "date": "2016-12-03",
        "permittedDepartureTime": {
          "kind": "qpxexpress#timeOfDayRange",
          "earliestTime": "06:00",
          "latestTime": "11:00"
        }
      }
    ],
    "saleCountry": "GB",
    "ticketingCountry": "GB",
    "solutions": 10
  }
}

我不知道这是您正在寻找的内容，或者您正在使用的API的哪一方，但输出是有效的JSON

与生成＆＃34; hello [object Object]＆＃34;

的原始代码相对

错误的请求。 HTTP POST到api
