wx.scanCodeCode扫的出小程序码，只是你要转义下 下面是我之前写的部分代码

 wx.scanCode({
                    success(res) {
                        console.log("res  扫描二维码");
                        console.log(res);
                        console.log(res.path);

                        wx.getLaunchOptionsSync((res) => {
                            console.log('getLaunchOptionsSync')
                            console.log(res)
                        })
                        if (res.path) {
                            let scene = res.path.split('?')[1].split('=');
                            const intype = scene[0];
                            console.log(scene)
                            scene = scene[1];
                            console.log(scene)
