这篇文章主要为大家详细介绍了php如何利用一个文件搞定微信jssdk配置，具有一定的参考价值，感兴趣的小伙伴们可以参考一下

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

GetWX.php

include "lib/Cache.php";

define($APPID, "……");

define($SECRET, "……")

if($_GET['Type'] == "access_token"){

// echo getAccess_token();

}

else if($_GET['Type'] == "jsapi_ticket"){

// echo getJsapi_ticket();

}

else if($_GET['Type'] == "config"){

$jsapi_ticket = getJsapi_ticket();

$nonceStr = "x".rand(10000,100000)."x"; //随机字符串

$timestamp = time(); //时间戳

$url = $_GET['url'];

$signature = getSignature($jsapi_ticket,$nonceStr, $timestamp, $url);

$result = array("jsapi_ticket"=>$jsapi_ticket, "nonceStr"=>$nonceStr,"timestamp"=>$timestamp,"url"=>$url,"signature"=>$signature);

echo json_encode($result);

}

function getSignature($jsapi_ticket,$noncestr, $timestamp, $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/');

//从缓存从读取键值 $key 的数据

$access_token = $cache -> get("access_token");

//如果没有缓存数据

if ($access_token == false) {

$url = 'https://api.weixin.qq.com/cgi-bin/token';

$data = array('grant_type'=>'client_credential','appid'=>$APPID,'secret'=>$SECRET);

$header = array();

$response = json_decode(curl_https($url, $data, $header, 5));

$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

* @param String $url 请求的url

* @param Array $data 要發送的數據

* @param Array $header 请求时发送的header

* @param int $timeout 超时时间，默认30s

*/

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

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_HTTPHEADER, $header);

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);

$response = curl_exec($ch);

if($error=curl_error($ch)){

die($error);

}

curl_close($ch);

return $response;

}

?>

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

}

}

?>
