云函数做图片内容检测img_sec_check - WXOPEN Club

我想利用云函数使用img_sec_check接口进行对图片内容进行检测，但不知道怎样写，请问有人这样子玩过吗？

// 云函数入口文件

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

//npm install request-promise

const rp = require('request-promise');

cloud.init()

// 云函数入口函数

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

//appid 和秘钥

const appid = 'wxxxxxxxxxxx',secret = 'aaaaaaaaaa';

const AccessToken_options = {

method: 'GET',

url: 'https://api.weixin.qq.com/cgi-bin/token',

qs: {

appid,

secret,

grant_type: 'client_credential'

},

json: true

};

//获取AccessToken

const resultValue = await rp(AccessToken_options);

const token = resultValue.access_token;

//下载图片

//从云存储取出文件或者直接从用户选择上传而来

const res = await cloud.downloadFile({

fileID: "cloud://xxxxxx"

});

//上传图片

const upload_options = {

method: 'POST',

uri: 'https://api.weixin.qq.com/wxa/img_sec_check?access_token=' + token,

formData: {

name: 'xxx',

file: {

value: res.fileContent,//res.fileContent

options: {

filename: 'test.jpg',

contentType: 'image/jpg'

}

},

headers: {

/* 'content-type': 'multipart/form-data' */

}

};

//检测图片

const checkRes =await rp(upload_options);

return checkRes;

}
