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

rush:PHP;"> ^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

GetWX.PHP

rush:PHP;"> $result = array("jsapi_ticket"=>$jsapi_ticket,"nonceStr"=>$nonceStr,"timestamp"=>$timestamp,"url"=>$url,"signature"=>$signature);
echo json_encode($result);
}

function getSignature($jsapi_ticket,$noncestr,$url){
$string1 = "jsapi_ticket=".$jsapi_ticket."&noncestr=".$noncestr."&timestamp=".$timestamp."&url=".$url;
$sha1 = sha1($string1);
return $sha1;
}

function getJsapi_ticket(){
$cache = new Cache();
$cache = new Cache(7000,'cache/'); //需要创建cache文件夹存储缓存文件。
//从缓存从读取键值 $key 的数据
$jsapi_ticket = $cache -> get("jsapi_ticket");
$access_token = getAccess_token();
//如果没有缓存数据
if ($jsapi_ticket == false) {
$access_token = getAccess_token();
$url = 'https://api.weixin.qq.com/cgi-bin/ticket/getticket';
$data = array('type'=>'jsapi','access_token'=>$access_token);
$header = array();
$response = json_decode(curl_https($url,$data,$header,5));
$jsapi_ticket = $response->ticket;
//写入键值 $key 的数据
$cache -> put("jsapi_ticket",$jsapi_ticket);
}
return $jsapi_ticket;
}

function getAccess_token(){
$cache = new Cache();
$cache = new Cache(7000,'cache/');

$access_token = $response->access_token;
//写入键值 $key 的数据
$cache -> put("access_token",$access_token);
}
return $access_token;
}

/** curl 获取 https 请求

  function curl_https($url,$data=array(),$header=array(),$timeout=30){
  $ch = curl_init();
  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false); // 跳过证书检查

Cache.PHP 不知道哪位写的源代码~

rush:PHP;"> //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
}

}
?>
