云开发检验图片是否有违规内容

客户端

mIsImg() {
var that = this
wx.chooseImage({
count: 1,
sourceType: ['album'],
success: function(res) {
if (!res.tempFilePaths[0]) {
return;
}
console.log(JSON.stringify(res))
if (res.tempFiles[0] && res.tempFiles[0].size > 1024 * 1024) {
wx.showToast({
title: '图片不能大于1M',
icon: 'none'
})
return;
}
wx.getFileSystemManager().readFile({
filePath: res.tempFilePaths[0],
success: buffer => {
console.log(buffer.data)
wx.cloud.callFunction({
name: 'imgCheck',
data: {
value: buffer.data
}
}).then(
imgRes => {
console.log(JSON.stringify(imgRes))
if (imgRes.result.errorCode == '87014') {
wx.showToast({
title: '图片含有违法违规内容',
