php一个文件搞定微信jssdk配置
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){
varlatitude=res.latitude;//纬度，浮点数，范围为90~-90
varlongitude=res.longitude;//经度，浮点数，范围为180~-180。
plus2.storage.setItem("latitude",latitude);
plus2.storage.setItem("longitude",longitude);
}
});
});
