谷歌反向地理編碼從經緯度得到地址

Question

我的字符串格式是">RPV21305+1134038+7772277800000012;ID=0011<" 我分離經緯度，如下面的代碼。但是我無法通過谷歌API訪問緯度和經度的地址。我的程序需要反向地理代碼。

我的計劃是

     try { 
      FileReader fileReader = new FileReader(fileName); 
      BufferedReader bufferedReader = new BufferedReader(fileReader); 
      while((line = bufferedReader.readLine()) != null) { 
       System.out.println(line); 
       int se = line.endsWith("<")? (line.length() - 1) : line.length(); 
       System.out.println("se-----------------------------"+se); 
       String parsedstring = line.substring(1,se); 
       System.out.println("parsedString"+parsedstring); 
       String T[] = parsedstring.split(";"); 
       System.out.println("ttttt-----------------------------"+T[0]);

你需要像這樣的代碼

GeoApiContext gtx = new GeoApiContext().setApiKey("**<<<<your-key-here>>>>**"); 
try { 
    GeocodingResult[] gResp = GeocodingApi.newRequest(gtx).latlng(new LatLng(37, -121)).await(); 
    System.out.println(gResp[0].formattedAddress); 
} catch (Exception e) { 
    // TODO Auto-generated catch block 
    e.printStackTrace(); 

同時確保谷歌的API是從控制檯啓用，你有你的關鍵。有了這兩個你應該得到的輸出如下所示，

信息：請求：https://maps.googleapis.com/maps/api/geocode/json?key=你的鑰匙 &經緯度= 37.38000000％2C-121.88000000 1685萊德勒CIR，聖何塞，加利福尼亞州95131，USA

在其下方的地址解析API是HTTP請求，所以如果你願意，你可以嘗試伸直以及

類似下面也應努力

https://maps.googleapis.com/maps/api/geocode/json?latlng=23,82.5 

要在罐子您的評論添加以下的依賴，如果你使用的是Java代碼

<dependency> 
    <groupId>com.google.maps</groupId> 
    <artifactId>google-maps-services</artifactId> 
    <version>0.1.15</version> 
</dependency> 

這幾乎在以下進口

拉

import com.google.maps.GeoApiContext; 
import com.google.maps.GeocodingApi; 
import com.google.maps.GeocodingApiRequest; 
import com.google.maps.model.GeocodingResult;
