1. 小程序请求代码
- onLoad: function (options) {
- var that = this
- api.Login(function (login) {
- var codeModel = new function () { }
- codeModel.scene = login.UserId
- codeModel.width=430
- codeModel.auto_color = false
- codeModel.line_color = { "r": "0", "g": "0", "b": "0" }
- console.log(----)
- api.RequestApiURL("WeixinAPI/CreateMyCode", { data: JSON.stringify(codeModel)}, function (e) {
- console.log(e)
- wx.hideLoading()
- console.log(e.data.data)
- that.setData({
- imgurl: e.data.data
- })
- })
- })
- }
2. 后台代码 (代理请求获取二维码的数据流)
- public string CreateMyCode(string data)
- {
- string gettokenurl = string.Format("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}", "appid", "AppSecret");
- string access_token = GetwebRequest(gettokenurl);
- if (access_token.IndexOf("access_token") > 0)
- {
- access_token = access_token.Substring(access_token.IndexOf(":") + 2,
- access_token.IndexOf(",") - access_token.IndexOf(":") - 3);
- }
- string url = string.Format("http://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token={0}", access_token);
- var io = PostMoths(url, data);
- byte[] by = StreamToBytes(io);
- var rs = new ReturnResult<byte[]>(by);
- return rs.Serialize();
- }
3. 二维码显示
- <view class="weui-media-box__hd_in-appmsg">
- <image class="weui-media-box__thumb" src="data:image/jpeg;base64,{{imgurl}}" />
- </view>
