根据ip获取用户地址-百度

摘要: 百度API方式通过ip获取用户地址，还有淘宝、新浪等等方式

百度的Api：GET请求
https://openapi.baidu.com/rest/2.0/iplib/query?access_token={access_token}&ip={ip}
这是我的，可以测下：

https://openapi.baidu.com/rest/2.0/iplib/query?access_token=23.8c3b9a489ff5f9b276ae49a54166fecc.2592000.1518836471.2307466515-10709969&ip=116.226.62.127

返回的结果如下：

{"116.226.62.127":{"province":"\u4e0a\u6d77","city":"\u4e0a\u6d77"}}

一、如何获取access_token

链接中有个access_token，字面意思就是用户访问令牌，怎么来的呢？

1、首先成为百度开发者，创建个工程

2、创建好如下

3、拿到access_token

百度不会显式给出access_token，有种投机的方法就是根据API KEY拿到：

通用浏览器get请求
https://openapi.baidu.com/oauth/2.0/authorize
?response_type=token&client_id={你的API KEY}&redirect_uri=oob&scope=netdisk

请求成功之后，浏览器上的链接就会变掉，并出现access_token

二、拿到了access_token，代码中解析数据即可

1、关键代码就这些

JSON: import com.alibaba.fastjson.JSON;

**********************************************************************************

/**

private static final String ACCESS_TOKEN = "23.8c3b9a489ff5f9b276ae49a54166fecc.2592000.1518836471.2307466515-10709969";

private static final RestTemplate REST_TEMPLATE = new RestTemplate();

private static String requestGetType(String url, Map<String, Object> uriVariables) {
return REST_TEMPLATE.getForObject(url, String.class, uriVariables);
}

/**

* @return BaiDuLocationDTO
*/
public static GeneralResponse<BaiDuLocationDTO> getLocationByBaiDu(String ip) {
String url = "https://openapi.baidu.com/rest/2.0/iplib/query?access_token={access_token}&ip={ip}";
Map<String, Object> uriVariables = new HashMap<>(2);
try {
uriVariables.put("access_token", URLEncoder.encode(ACCESS_TOKEN, "utf-8"));
uriVariables.put("ip", URLEncoder.encode(ip, "utf-8"));
} catch (UnsupportedEncodingException e) {
return GeneralResponse.FAIL;
}
String result = requestGetType(url, uriVariables);
BaiDuLocationDTO successObject = JSON.parseObject(result).getObject(ip, BaiDuLocationDTO.class);
if (successObject == null) {
BaiDuLocationErrorDTO object = JSON.parseObject(result, BaiDuLocationErrorDTO.class);
if ("110".equals(object.getErrorCode())) {
return new GeneralResponse<>(UserExceptionEnum.BAI_DU_ERROR_TOKEN_NOT_EXIST);
} else if ("100".equals(object.getErrorCode())) {
return new GeneralResponse<>(UserExceptionEnum.BAI_DU_ERROR_PARAMETER, object.getErrorMsg());
} else if ("2".equals(object.getErrorCode())) {
return new GeneralResponse<>(UserExceptionEnum.BAI_DU_ERROR_SYSTEM_UNAVAILABLE);
} else {
return new GeneralResponse<>(UserExceptionEnum.BAI_DU_ERROR_OTHER, object.getErrorMsg());
}
}
return new GeneralResponse<>(successObject);
}

public class BaiDuLocationDTO implements Serializable {
