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);

}

});

});

服务端

Cache.php

不知道哪位写的源代码~

class Cache {

private $cache_path;

//path for the cache

private $cache_expire;

//seconds that the cache expires

//cache constructor, optional expiring time and cache path

public function Cache($exp_time = 3600, $path = "cache/") {

$this -> cache_expire = $exp_time;

$this -> cache_path = $path;

}

//returns the filename for the cache

private function fileName($key) {

return $this -> cache_path . md5($key);

}

//creates new cache files with the given data, $key== name of the cache, data the info/values to store

public function put($key, $data) {

$values = serialize($data);

$filename = $this -> fileName($key);

$file = fopen($filename, 'w');

if ($file) {//able to create the file

fwrite($file, $values);

fclose($file);

} else

return false;

}

//returns cache for the given key

public function get($key) {

$filename = $this -> fileName($key);

if (!file_exists($filename) || !is_readable($filename)) {//can't read the cache

return false;

}

if (time() < (filemtime($filename) + $this -> cache_expire)) {//cache for the key not expired

$file = fopen($filename, "r");

// read data file

if ($file) {//able to open the file

$data = fread($file, filesize($filename));

fclose($file);

return unserialize($data);

//return the values

} else

return false;

} else

return false;

//was expired you need to create new

}

}
