wx.getLocation()是获取用户地址信息,没授权就会弹出授权框; wx.getSetting()是获取用户授权状态; wx.openSetting()是跳转至授权页面。 你自己先搞清楚微信API的含义
有没大佬帮忙看下代码sign: function () { var that = this const la1 = 31.991362 const lo1 = 118.737908 wx.getLocation({ type: 'gcj02', success: function (res) { const la2 = res.latitude const lo2 = res.longitude var La1 = la1 * Math.PI / 180.0; var La2 = la2 * Math.PI / 180.0; var La3 = La1 - La2; var Lb3 = lo1 * Math.PI / 180.0 - lo2 * Math.PI / 180.0; var s = 2 * Math.asin(Math.sqrt(Math.pow(Math.sin(La3 / 2), 2) + Math.cos(La1) * Math.cos(La2) * Math.pow(Math.sin(Lb3 / 2), 2))); s = s * 6378.137;//地球半径 s = Math.round(s * 10000) / 10000; if (s > 0.2) { wx.showToast({ title: '距离不够' + s, icon: 'none' }) console.log("距离不够" + s) } else { wx.showToast({ title: '签到成功', icon: 'success' }) console.log("sssssssss===" + s) } } }) //判断是否获得了用户地理位置授权 wx.getSetting({ success: function(res){ if (!res.authSetting['scope.userLocation']){ wx.openSetting({ success: function (res) { if (res.authSetting["scope.userLocation"]) { wx.showToast({ title: '授权成功', icon: 'success', duration: 1000 }) } } }) } } }) }
