Applet cloud development micro-channel (cloud function) got sent using http, https request server data

Why send http requests using cloud functions?

 

1, from 5 credible domain name restrictions, other means that may not be credible domain name

2, the requested domain name can not record

Note: The above rule when I learned is still valid!

 Want to send http request in the cloud function, must rely on external packge to complete the tutorial I have learned in this article is got

Test code is as follows:

Add the pages of named http

miniprogram：pages/http/http.wxml

<button bindtap="http">http</button

 

miniprogram：pages/http/http.js

. 1  Page ({
 2      HTTP: function (E) {
 . 3        wx.cloud.callFunction ({ // call the function cloud 
. 4          name: 'HTTP'            // cloud function called HTTP 
. 5        .}) The then (RES => {　　　　　　// Promise 
. 6          the console.log (the JSON.parse (res.result))
 . 7        })
 . 8      },
 . 9  
10 })

 

 New function named http cloud and cloud function installed in the directory http got

npm install --save got

　　

Edit http.js

cloudfunctions：http/http.js

1  // cloud function entry file 
2 const = Cloud the require ( 'WX-Server-SDK' )
 . 3  
. 4 const = GOT the require ( 'GOT'); // reference GOT 
. 5  
. 6  cloud.init ()
 . 7  
. 8  // cloud function entry function 
. 9 exports.main the async = (Event, context) => {
 10    // the let getResponse the await GOT = ( 'httpbin.org/get') // do the GET request URL test httpbin.org 
. 11    // return getResponse .body 
12 is    the let postResponse the await GOT = ( 'httpbin.org/post' , { 
 13 is      Method: 'the POST', // POST request 
14      headers: {
15        'the Type-the Content': 'file application / json' 
 16      },
 . 17      body: the JSON.stringify ({ // the json data (objects) to parse the string 
18 is        title: "URL" ,
 . 19        value: 'anipc.com'
 20 is      })
 21 is    })
 22 is  
23 is    return postResponse.body // return data 
24 }

 

 Here only we get tested and POST request methods, please refer to the other got the document 

After uploading and saving deployment

 

 

It should be noted: the cloud now need to install depend on the local function, you can install the cloud-dependent, which means you are not installed in the new cloud wx.server.sdk function, if the point of upload and deploy: all the files, then we would first locally installed locally dependent.

npm install --save wx-server-sdk

 

have a test:

get
