本篇主要介绍在unity中接入高德定位sdk。
方法1、不用接入sdk，直接使用unity原生的方法，获得经纬度之后，以get请求得到城市相关信息。
代码如下：
using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Net;
using System.Text;
using UnityEngine;
public class GPSDemo : MonoBehaviour
{
private AndroidJavaClass unity;
IEnumerator Start()
{
if (unity == null)
{
unity = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
}
if (!Input.location.isEnabledByUser)
{
Input.location.Start();
yield break;
}
// Start service before querying location
Input.location.Start();
// Wait until service initializes
int maxWait = 20;
while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
{
yield return new WaitForSeconds(1);
maxWait--;
}
// Service didn't initialize in 20 seconds
if (maxWait < 1)
{
print("Timed out");
yield break;
}
// Connection has failed
if (Input.location.status == LocationServiceStatus.Failed)
{
print("Unable to determine device location");
yield break;
}
else
{
// Access granted and location value could be retrieved
Debug.LogError("Location: " + Input.location.lastData.latitude + " " + Input.location.lastData.longitude + " " + Input.location.lastData.altitude + " " + Input.location.lastData.horizontalAccuracy + " " + Input.location.lastData.timestamp);
//取出位置的经纬度
string str = Input.location.lastData.longitude + "," + Input.location.lastData.latitude;
Debug.Log("定位信息" + GetLocationByLngLat(str));
}
// Stop service if there is no need to query location updates continuously
Input.location.Stop();
}
const string key = "6bda73179a87a92394489045b32a0f46"; //去高德地图开发者申请 这个key的流量不知道被哪位同学用完了，
/// 失败返回""
public string GetLocationByLngLat(string LngLatStr, int timeout = 10000)
{
string url = $"http://restapi.amap.com/v3/geocode/regeo?key={key}&location={LngLatStr}";
return GetLocationByURL(url, timeout);
}
public string GetLocationByLngLat(double lng, double lat, int timeout = 10000)
{
string url = $"http://restapi.amap.com/v3/geocode/regeo?key={key}&location={lng},{lat}";
Debug.LogError("url = " + url);
return GetLocationByURL(url, timeout);
}
private string GetLocationByURL(string url, int timeout = 10000)
{
string strResult = "";
try
{
HttpWebRequest req = WebRequest.Create(url) as HttpWebRequest;
req.ContentType = "multipart/form-data";
req.Accept = "*/*";
//req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)";
req.UserAgent = "";
req.Timeout = timeout;
req.Method = "GET";
req.KeepAlive = true;
HttpWebResponse response = req.GetResponse() as HttpWebResponse;
using (StreamReader sr = new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
strResult = sr.ReadToEnd();
}
Debug.LogError("xxx123" + strResult);
}
catch (Exception ex)
{
Debug.LogError("ex = " + ex.ToString());
strResult = "";
}
return strResult;
}
这个就可以了。
你可以在web浏览器直接如下格式的请求：
http://restapi.amap.com/v3/geocode/regeo?key=6bda73179a87a92394489045b32a0f46&location=74,40
74,40是经纬度，逗号隔开。
key=6bda73179a87a92394489045b32a0f46 是人家的web开发的key。自己可以自己申请，申请的过程后文会介绍。这里先暂时用别人的。
2、使用sdk的接入
这里介绍的是android平台下接入高德sdk。
下载sdk：
https://lbs.amap.com/api/android-navi-sdk/download/
key的获取。
首先德注册高德开发账号，网址：https://lbs.amap.com/
注册之后，到达控制台：https://console.amap.com/dev/key/app
点击管理Key
创建新应用，随便起个名字。
1：起个刚才创建新应用的名字
2：服务平台选择android
3、发布版安全码SHA1获取方式：
3.1到达unity的项目：
选择keystore存放的路径，我这里选择在D盘了。
记住你的密码，这个在打包的时候会用到。
3.2到android studio中敲入如下命令：keytool -list -v -keystore D:\user.keystore
D:\user.keystore就是我们刚才的那个keystore文件。
得到：
ok，把这个SHA1，复制给上面的那个4开发SHA1中即可。
调试版的也用此命令：keytool -list -v -keystore debug.keystore
debug.keystore是android studio自带的：
在下：这个在安装了android studio之后就有了。
ok，同样也会得到：
将其复制到5：
4、最后一步是packageName：这个名字是你的android的应用包名：
ok，有了这个key之后，就可以了。
下面是代码部分：
android部分：

再次之前，还要导入jar包：
一个untiy的，一个是高度sdk的jar包。
rebuild失败，可以换代理：这是整个工程的build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }

ok，这个之后：
