我们正在使用Google的地理位置API来获取wifi接入点的latlong。我们看到的结果不一致。谷歌的API在不同的盒子上返回不同的latlong。当我在我的开发盒上测试时,我得到的latlong指向美国的一个位置。当我在亚马逊ec2盒子上测试相同的东西时,我得到了指向日本某个位置的latlong。还有其他人对Google的GeoLocation API有相同的看法吗? 下面是两个主机的代码和响应字符串。两台主机上的JDK和JSON jar版本相同。
public void testWifiIdMappingApi() {
String apiUrl = "https://www.googleapis.com/geolocation/v1/geolocate?key=xxxxxxxxxxxxxxxxxxxxxxxx";
InputStream inputStream = null;
HttpsURLConnection con = null;
DataOutputStream wr = null;
try {
URL url = new URL(apiUrl);
con = (HttpsURLConnection) url.openConnection();
con.setRequestMethod("POST");
con.setRequestProperty("Content-Type", "application/json");
con.setDoInput(true);
con.setDoOutput(true);
con.connect();
JSONObject obj = new JSONObject();
JSONArray wifiAry = new JSONArray();
JSONObject wifiObj = new JSONObject();
wifiObj.put("macAddress", "6c:f3:7f:4b:37:74");
wifiObj.put("signalStrength", 60);
wifiAry.add(wifiObj);
wifiObj = new JSONObject();
wifiObj.put("macAddress", "6c:f3:7f:4b:37:75");
wifiObj.put("signalStrength", 60);
wifiAry.add(wifiObj);
obj.put("wifiAccessPoints", wifiAry);
System.out.println(obj.toString());
wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(obj.toString());
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
inputStream = null;
if (responseCode == HttpsURLConnection.HTTP_OK) {
inputStream = con.getInputStream();
} else {
inputStream = con.getErrorStream();
}
final char[] buffer = new char[4096];
StringBuilder response = new StringBuilder();
Reader r = new InputStreamReader(inputStream, "UTF-8");
int read;
do {
read = r.read(buffer, 0, buffer.length);
if (read > 0) {
response.append(buffer, 0, read);
}
} while (read >= 0);
System.out.println(new java.util.Date() + " - "
+ response.toString());
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (inputStream != null)
inputStream.close();
if (wr != null)
wr.close();
if (con != null)
con.disconnect();
} catch (Exception e) {
}
}
}
输入JSON字符串
{ “wifiAccessPoints”:[{ “signalStrength”:60, “MACADDRESS”: “6C:F3:7F:4B:37:74”}, { “signalStrength”:60, “MACADDRESS”: “6C:F3:7F:4B:37:75”}]}
对亚马逊ec2主机的回应 { “地点”: { “lat”:40.603124, “lng”:140.463922 }, “准确度”:122000.0 }
我的开发框响应(Windows 7)
{ “地点”: { “lat”:37.593392, “lng”: - 122.04383 }, “准确度”:22000.0 }
答案 0 :(得分:0)
您可能希望在POST正文中将considerIp
字段传递为False。当无线路由器无法正常工作时,这将是谷歌确定的位置。
