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);
}
});
});
