最近做微信小程序項(xiàng)目中遇到根據(jù)后臺(tái)接口獲取城市某個(gè)區(qū)域內(nèi)的信息，后臺(tái)接口要求傳入城市的區(qū)域名稱弥奸，例如上海市楊浦區(qū)蛤克，小程序官方地址提供的API只能獲取到用戶當(dāng)前的經(jīng)緯度，如何通過經(jīng)緯度查詢到用戶的當(dāng)前位置成了一個(gè)問題闷祥。所以通過研究和查詢資料解決了這個(gè)問題娱颊，現(xiàn)共享給大家。
我是通過騰訊地圖逆地址解析凯砍，在通過經(jīng)緯度獲取詳細(xì)的位置信息數(shù)據(jù)箱硕。
根據(jù)騰訊地圖API，以圖文的方式說明如何獲取詳細(xì)的位置信息數(shù)據(jù)果覆。具體參考騰訊地圖Webservice API的介紹颅痊。地址：騰訊位置服務(wù)
step1:申請騰訊地圖密鑰（key），申請地址：申請密鑰
填寫完成后即可獲取到對應(yīng)的key值局待。

step2:通過小程序官方API獲取用戶當(dāng)前位置經(jīng)緯度斑响。然后根據(jù)騰訊Webservice API逆地址解析相關(guān)介紹，傳入獲取到的經(jīng)緯度钳榨，即可獲取舰罚。
示例代碼：
//獲取當(dāng)前位置經(jīng)緯度
wx.getLocation({
type: 'wgs84',
success: function (res) {
//console.log("獲取當(dāng)前經(jīng)緯度：" + JSON.stringify(res));
//發(fā)送請求通過經(jīng)緯度反查地址信息
var getAddressUrl = "https://apis.map.qq.com/ws/geocoder/v1/?location=" + res.latitude + "," + res.longitude + "&key=你的key值&get_poi=1";
common.Request(getAddressUrl, "get", "", function (ops) {
//console.log(JSON.stringify(ops));
})
}
})

獲取的位置示例，根據(jù)項(xiàng)目提取需要的數(shù)據(jù)薛耻。

在小程序里使用注意的地方：
- 需要在微信小程序后臺(tái)配置合法域名营罢；
- 測試時(shí)也可以在開發(fā)工具中選擇不校驗(yàn)安全域名。
