云函数中使用“request-promise”调用腾讯地图实现地址解析（地址转坐标）报400错误？ - WXOPEN Club

业务逻辑如下：

1 云函数A获取客户名称列表；

2 云函数B通过调用腾讯地图WebService API实现地址解析（地址转坐标），试图实现输入“客户名称”，返回客户名称所在地的经纬度坐标(X,Y)。

// 云函数入口文件

const cloud = require('wx-server-sdk')

//const request = require('request')

const rp = require('request-promise')

//const soap = require('soap')

cloud.init()

// 云函数入口函数

exports.main = async (event, context) => {

const wxContext = cloud.getWXContext()

var latitudeAndLongitude = null

//request.get()

var options = {

uri: 'https://apis.map.qq.com/ws/geocoder/v1/?address=' + event.address + '&key=' + event.developerKey,

method: 'GET',

json: true

}

latitudeAndLongitude = await rp(options).then(function (res) {

return res

}).catch(function (err) {

return err

})

return {

event,

openid: wxContext.OPENID,

appid: wxContext.APPID,

unionid: wxContext.UNIONID,

latitudeAndLongitude: latitudeAndLongitude

}

云函数B代码如下：

// 云函数入口文件

const cloud = require(‘wx-server-sdk’)

const rp = require(‘request-promise’)

//const soap = require(‘soap’)

cloud.init()

// 云函数入口函数

exports.main = async (event, context) => {

const wxContext = cloud.getWXContext()

var latitudeAndLongitude = null

//request.get()

var options = {

uri: ‘https://apis.map.qq.com/ws/geocoder/v1/?address=’ + event.address + ‘&key=’ + event.developerKey,

method: ‘GET’,

json: true

}

latitudeAndLongitude = await rp(options).then(function (res) {

return res

}).catch(function (err) {

return err

})

return {

event,

openid: wxContext.OPENID,

appid: wxContext.APPID,
