我用Java 调用百度鹰眼《实时位置搜索》 返回值是{"status":210,"message":"APP IP校验失败"}，请问这是什么问题
public static final String yingYan_AK_S="******";
/**
* 百度鹰眼serviceID
*/
public static final String yingyan_SERVICE_ID = "******";
public static final String yingyan_URL="http://yingyan.baidu.com/api/v3/";
/**
* 百度鹰眼提交方式
*/
public static final String yingyan_POST="POST";
public static final String yingyan_GET="GET";
//创建entity，并赋属性信息
public static class yingyanEntity{
public static final String SEARCH = "entity/search";
public static final String BOUNDSEARCH = "entity/boundsearch";
/**
*
*/
public static final String AROUNDSEARCH = "entity/aroundsearch";
/**
* 检索符合条件的entity，返回entity属性信息和最新位置。可用于列出entity，也可用于批量查询多个entitiy的位置
*/
public static final String DISTRICTSEARCH = "entity/districtsearch";
}
public static String yingyanReq(String urlReq, String param, String method) {
try {
//Get请求，拼装参数
if (yingyan_GET.equals(method)) {
urlReq = urlReq + "?" + param;
}
//创建URL对象
URL url = new URL(urlReq);
//返回一个URLConnection对象，它表示到URL所引用的远程对象的连接
URLConnection urlConnection = url.openConnection();
//POST请求，写入参数
if (yingyan_POST.equals(method)) {
// 设置doOutput属性为true表示将使用此urlConnection写入数据
urlConnection.setDoOutput(true);
// 定义待写入数据的内容类型，我们设置为application/x-www-form-urlencoded;charset=UTF-8"类型
urlConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");
// 得到请求的输出流对象
OutputStreamWriter out = new OutputStreamWriter(urlConnection.getOutputStream());
// 把数据写入请求的Body
out.write(param);
out.flush();
out.close();
}
InputStream inputStream = urlConnection.getInputStream();
String encoding = urlConnection.getContentEncoding();
String result = IOUtils.toString(inputStream, encoding);
System.out.println(result);
return result;
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
return null;
}
}
public static void main(String[] args) {
String urlReq = yingyan_URL + yingyanEntity.DISTRICTSEARCH;
String param = "ak="+YingYan_AK_S+"&service_id="+yingyan_SERVICE_ID+"&keyword=海淀区";
yingyanReq(urlReq, param, yingyan_GET);
}
