php一个文件搞定微信jssdk配置:
包括缓存,包括https通讯,获取微信access_token,签名什么的都有。但是防范性编程做得比较少,商业用的话,需要完善下代码。
使用姿势^ajax(Common.ServerUrl + "GetWX.php", { data: {Type: "config",url: location.href.split("#")[0] }, dataType: "json", type: "get", timeout: 5000, success: function(data) {wx.config({ debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来,若要查看传入的参数,可以在pc端打开,参数信息会通过log打出,仅在pc端时才会打印。 appId: "……", // 必填,公众号的唯一标识 timestamp: data.timestamp, // 必填,生成签名的时间戳 nonceStr: data.nonceStr, // 必填,生成签名的随机串 signature: data.signature, // 必填,签名,见附录1 jsApiList: ["getLocation"] // 必填,需要使用的JS接口列表,所有JS接口列表见附录2}); }})wx.ready(function() { wx.getLocation({type: "wgs84", // 默认为wgs84的gps坐标,如果要返回直接给openLocation用的火星坐标,可传入"gcj02"success: function(res) { var latitude = res.latitude; // 纬度,浮点数,范围为90 ~ -90 var longitude = res.longitude; // 经度,浮点数,范围为180 ~ -180。 plus2.storage.setItem("latitude", latitude); plus2.storage.setItem("longitude", longitude);} });});
