微信公众号获取用户当前经纬度

啦啦啦，踩了半天坑，终于成功了，总结一下php端，第一步：先封装一个类（本人用的TP5,阅读者参考类里面的类容即可）<?phpnamespace app\shangjia\controller;use app\common\controller\Base;class JSSDK extends Base{private $appId;private $appSecret;public function __construct($appId, $appSecret) {$this->appId = $appId;$this->appSecret = $appSecret;}public function getSignPackage($url) {$jsapiTicket = $this->getJsApiTicket();// 注意 URL 一定要动态获取，不能 hardcode.划重点啊！划重点啊！url一定用前端传过来的值啊，不能自己写死啊，前端怎么传url下面会讲$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ? "https://" : "http://";$url =$url; //"$protocol$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";（我刚开始用这个就错了，错了。。。。）$timestamp = time();$nonceStr = $this->createNonceStr();// 这里参数的顺序要按照 key 值 ASCII 码升序排序$string = "jsapi_ticket=$jsapiTicket&noncestr=$nonceStr&timestamp=$timestamp&url=$url";$signature = sha1($string);$signPackage = array("appId"=> $this->appId,"nonceStr" => $nonceStr,"timestamp" => $timestamp,"url" => $url,"signature" => $signature,"rawString" => $string);return $signPackage;}private function createNonceStr($length = 16) {$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";$str = "";for ($i = 0; $i < $length; $i++) {$str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);}return $str;}private function getJsApiTicket() {// jsapi_ticket 应该全局存储与更新，以下代码以写入到文件中做示例$data = json_decode(file_get_contents("jsapi_ticket.json"));if ($data->expire_time < time()) {$accessToken = $this->getAccessToken();// 如果是企业号用以下 URL 获取 ticket// $url = "https://qyapi./cgi-bin/get_jsapi_ticket?access_token=$accessToken";$url = "https://api./cgi-bin/ticket/getticket?type=jsapi&access_token=$accessToken";$res = json_decode($this->httpGet($url));$ticket = $res->ticket;if ($ticket) {$data->expire_time = time() + 7000;$data->jsapi_ticket = $ticket;$fp = fopen("jsapi_ticket.json", "w");fwrite($fp, json_encode($data));fclose($fp);}} else {$ticket = $data->jsapi_ticket;}return $ticket;}private function getAccessToken() {// access_token 应该全局存储与更新，以下代码以写入到文件中做示例$data = json_decode(file_get_contents("access_token.json"));if ($data->expire_time < time()) {// 如果是企业号用以下URL获取access_token// $url = "https://qyapi./cgi-bin/gettoken?corpid=$this->appId&corpsecret=$this->appSecret";$url = "https://api./cgi-bin/token?grant_type=client_credential&appid=$this->appId&secret=$this->appSecret";$res = json_decode($this->httpGet($url));$access_token = $res->access_token;if ($access_token) {$data->expire_time = time() + 7000;$data->access_token = $access_token;$fp = fopen("access_token.json", "w");fwrite($fp, json_encode($data));fclose($fp);}} else {$access_token = $data->access_token;}return $access_token;}private function httpGet($url) {$curl = curl_init();curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);curl_setopt($curl, CURLOPT_TIMEOUT, 500);curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);curl_setopt($curl, CURLOPT_URL, $url);$res = curl_exec($curl);curl_close($curl);return $res;}}第二步：public function test(){$url=$_POST['url'];//接收前端传递过来的url$jssdk=new JSSDK("替换成你自己的appid", "替换成你自己的appsecret");$res=$jssdk->GetSignPackage($url);return json(['code'=>200,'data'=>$res]);//返回的东西就是前端需要的！}

第三步：

$(function(){ //页面初始化，发起ajax请求 var pageUrl ={url:(window.location.href).split('#')[0]};$.ajax({url: "/shangjia/weizhi/test",type: "post", data: pageUrl,//前端传递urlsuccess: function (data) {var params=data.data//console.log(params);////console.log(params);/*配置 wx.config 参数*/wx.config({debug: false, // 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: params.appId, // 必填，企业号的唯一标识，此处填写企业号corpidtimestamp: params.timestamp, // 必填，生成签名的时间戳nonceStr: params.nonceStr, // 必填，生成签名的随机串signature: params.signature,// 必填，签名，见附录1jsApiList: ['checkJsApi','openLocation','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.checkJsApi({jsApiList: ['checkJsApi','openLocation','getLocation'],success: function (res) {if (res.checkResult.getLocation == false) {alert('你的微信版本太低，不支持微信JS接口，请升级到最新的微信版本！');return;}}});wx.getLocation({type: 'wgs84',success: function (res) {//alert(JSON.stringify(res));},cancel: function (res) {//alert('用户拒绝授权获取地理位置');}});wx.error(function(res){//alert("接口调取失败")});});

}

//好了，oj8k了
