1、前提:

http://lbsyun.baidu.com/apiconsole/key。

2、我这儿用的是tp3.2做的

3、WechatJs 是用到的类

Demo/test 是转换为百度坐标的方法

/** * 转换成百度坐标 */ public function test() { $latitude = $_POST['Latitude']; $longitude = $_POST['Longitude'];// //百度地图坐标转换官网:http://lbsyun.baidu.com/index.php?title=webapi/guide/changeposition $q = "http://api.map.baidu.com/geoconv/v1/?coords=".$longitude.",".$latitude."&from=1&to=5&ak=CVwQRrOiPCBuNgjWU3fNRvaYhkMBaI4A"; $resultQ = json_decode(file_get_contents($q),true); $latitudeNew = $resultQ["result"][0]["y"]; $longitudeNew = $resultQ["result"][0]["x"]; $returnDataArray = array("latitudeNew"=>$latitudeNew,"longitudeNew"=>$longitudeNew); $this->ajaxReturn($returnDataArray); }

通过转换过的百度坐标(经纬度)来获取当前位置详细信息

/** * 获取当前位置详细信息 */ public function test_two() { $latitude = '38.054662894458'; $longitude = '114.48129456957'; $q = "http://api.map.baidu.com/geocoder/v2/?location=".$latitude.",".$longitude."&output=json&pois=0&ak=CVwQRrOiPCBuNgjWU3fNRvaYhkMBaI4A"; $result = $this->http_request($q); $resultArry = json_decode($result,true); dump($resultArry); dump($resultArry['result']['formatted_address']); die; } /** * curl */ protected function http_request($url, $data = null) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE); if (!empty($data)){ curl_setopt($curl, CURLOPT_POST, 1); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $output = curl_exec($curl); curl_close($curl); return $output; }

使用百度地图逆地址解析遇到的一个小坑: 转载自: https://blog.csdn.net/xiaolong20081/article/details/79604476 区别于上述代码的一个请求地址:

http://api.map.baidu.com/geocoder/v2/?ak=xxx&coordtype=wgs84ll&callback=renderReverse&location=37.58585,118.8889&output=xml&pois=1。

用百度地图官网给的请求地址会多出一个 renderReverse&&renderReverse 拿到值很开心的用上json_decode,结果刷新查看返回NULL,竟然是空,不甘心的我以特么刷新了几遍,还是空,这是逗我吗?又跑去检查代码,代码没错啊。最后通过百度找到了正确的解决办法,原来是多了 callback=renderReverse 这个javascript函数名,去掉这个就行了。另一种方法是通过正则来匹配出json格式数据,

$str= 'renderReverse&&renderReverse({"status":0,"result":{"location":{"lng":116.32298703399,"lat":39.983424051248},"formatted_address":"北京市海淀区中关村大街27号1101-08室","business":"中关村,人民大学,苏州街","addressComponent":{"adcode":"110108","city":"北京市","country":"中国","direction":"附近","distance":"7","district":"海淀区","province":"北京市","street":"中关村大街","street_number":"27号1101-08室","country_code":0},"pois":[{"addr":"北京北京海淀海淀区中关村大街27号(地铁海淀黄庄站A1","cp":"NavInfo","direction":"内","distance":"0","name":"北京远景国际公寓(中关村店)","poiType":"房地产","point":{"x":116.3229458916,"y":39.983610361549},"tag":"房地产","tel":"","uid":"35a08504cb51b1138733049d","zip":""},{"addr":"海淀区中关村北大街27号","cp":"NavInfo","direction":"附近","distance":"25","name":"中关村大厦","poiType":"房地产","point":{"x":116.32285606105,"y":39.983568897877},"tag":"房地产;写字楼","tel":"","uid":"06d2dffdaef1b7ef88f15d04","zip":""},{"addr":"中关村大街29","cp":"NavInfo","direction":"北","distance":"62","name":"海淀医院激光整形美容部","poiType":"医疗","point":{"x":116.32317046798,"y":39.983016046485},"tag":"医疗;专科医院","tel":"","uid":"b1c556e81f27cb71b4265502","zip":""},{"addr":"中关村大街27号中关村大厦1层","cp":"NavInfo","direction":"附近","distance":"1","name":"中国人民财产保险中关村营业部","poiType":"金融","point":{"x":116.32298182382,"y":39.983416864194},"tag":"金融;投资理财","tel":"","uid":"060f5e53137d20d7081cc779","zip":""},{"addr":"北京市海淀区","cp":"NavInfo","direction":"东北","distance":"58","name":"北京市海淀医院-输血科","poiType":"医疗","point":{"x":116.322685383,"y":39.983092063819},"tag":"医疗;其他","tel":"","uid":"cf405905b6d82eb9b55f1e89","zip":""},{"addr":"北京市海淀区中关村大街27号中关村大厦二层","cp":"NavInfo","direction":"附近","distance":"0","name":"眉州东坡酒楼(中关村店)","poiType":"美食","point":{"x":116.32298182382,"y":39.983423774823},"tag":"美食","tel":"","uid":"2c0bd6c57dbdd3b342ab9a8c","zip":""},{"addr":"北京市海淀区中关村大街29号(海淀黄庄路口)","cp":"NavInfo","direction":"东北","distance":"223","name":"海淀医院","poiType":"医疗","point":{"x":116.32199368776,"y":39.982083099537},"tag":"医疗;综合医院","tel":"","uid":"fa01e9371a040053774ff1ca","zip":""},{"addr":"北京市海淀区中关村大街28号","cp":"NavInfo","direction":"西北","distance":"229","name":"海淀剧院","poiType":"休闲娱乐","point":{"x":116.32476945179,"y":39.982622137118},"tag":"休闲娱乐;电影院","tel":"","uid":"edd64ce1a6d799913ee231b3","zip":""},{"addr":"海淀黄庄地铁站旁","cp":"NavInfo","direction":"西北","distance":"375","name":"中发电子市场(中关村大街)","poiType":"购物","point":{"x":116.32529945204,"y":39.981537146849},"tag":"购物;家电数码","tel":"","uid":"69130523db34c811725e8047","zip":""},{"addr":"北京市海淀区知春路128号","cp":"NavInfo","direction":"西北","distance":"434","name":"泛亚大厦","poiType":"房地产","point":{"x":116.32600013033,"y":39.981516414381},"tag":"房地产;写字楼","tel":"","uid":"d24e48ebb9991cc9afee7ade","zip":""}],"poiRegions":[],"sematic_description":"北京远景国际公寓(中关村店)内0米","cityCode":131}})';

preg_match('/\(.*\)/', $str, $result);var_dump($result);

第三办法是用str_replace和substr和strlen解决,这里就不给出具体的写法了,有需要的可以去百度一下用法。

注意事项: 1.获取微信地理位置时 要保证JS安全域名 网址不带http/https。
