php一個文件搞定微信jssdk配置
學習PHP的小伙伴在處理微信jssdk配置的時候可能會遇到一些問題。以下是百分網小編精心為大家整理的php一個文件搞定微信jssdk配置，希望對大家有所幫助!更多內容請關注應屆畢業生網!
包括緩存，包括https通訊，獲取微信access_token，簽名什么的都有。但是防范性編程做得比較少，商業用的話，需要完善下代碼。
使用姿勢
?
^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, /pic/p>
appId: '……', /pic/p>
timestamp: data.timestamp, /pic/p>
nonceStr: data.nonceStr, /pic/p>
signature: data.signature, /pic/p>
jsApiList: ["getLocation"] /pic/p>
});
}
})
wx.ready(function() {
wx.getLocation({
type: 'wgs84', /pic/p>
success: function(res) {
var latitude = res.latitude; /pic/p>
var longitude = res.longitude; /pic/p>
plus2.storage.setItem("latitude", latitude);
plus2.storage.setItem("longitude", longitude);
}
});
});
服務端
GetWX.php
?

Cache.php
不知道哪位寫的源代碼~
?
class Cache {
private $cache_path;
/pic/p>
private $cache_expire;
/pic/p>
/pic/p>
public function Cache($exp_time = 3600, $path = "cache/") {
$this -> cache_expire = $exp_time;
$this -> cache_path = $path;
}
/pic/p>
private function fileName($key) {
return $this -> cache_path . md5($key);
}
/pic/values to store
public function put($key, $data) {
$values = serialize($data);
$filename = $this -> fileName($key);
$file = fopen($filename, 'w');
if ($file) {/pic/p>
fwrite($file, $values);
fclose($file);
} else
return false;
}
/pic/p>

$filename = $this -> fileName($key);
if (!file_exists($filename) || !is_readable($filename)) {/pic/p>
return false;
}

/pic/p>

} else

return false;
