バックエンドのコードそんなに。
リクエストインターフェイス
uni.request({
url:"/wechat/getSignature",
method:"POST",
data:{
url: window.location.href
},
success: (res) => {
var signature = res.data.data
wx.config({
beta: true,
debug: false,
appId: "appid",
timestamp: signature.timestamp,
nonceStr: signature.noncestr,
signature: signature.signature,
jsApiList: ['onMenuShareAppMessage','onMenuShareTimeline','onMenuShareQQ','onMenuShareWeibo','onMenuShareQZone']
});
}
})
共有の初期化方法：
wx.ready(function(){
wx.onMenuShareAppMessage({
title: "",
desc: "",
link: '',
imgUrl: '',
success: function (res) {
}
}) ,
wx.onMenuShareTimeline({
title: '',
link: '',
imgUrl: '',
success: function () {
}
})
});
完全なコードのフロントエンド：
