嘿,我正在尝试从此服务(http://ip-api.com)获得响应,该响应基于ip为您提供纬度和经度:
因此,当您传递IP 55.130.54.69时,它将返回以下json:
read
http://ip-api.com/#55.130.54.69
因此,在服务中,我正在执行以下操作(我以此Best way to get geo-location in Java为指导):
EquationListJsonAdapter
因此,您可以看到我正在尝试在我的问题中获取上面的json,但我不知道如何,请给我指路吗?
答案 0 :(得分:2)
如果您需要以纯文本格式获取json,则可以尝试下一个:
@POST
@Path("/test2")
public void test2(@Context HttpServletRequest request) {
...
Response response = client.target("http://ip-api.com/json/" + ip)
.request(MediaType.TEXT_PLAIN_TYPE)
.header("Accept", "application/json").get();
String json = response.readEntity(String.class);
response.close();
// now you can do with json whatever you want to do
}
您还可以创建一个实体类,其中字段名称与json中的值名称匹配:
public class Geolocation {
private String query;
private String status;
private String continent;
// ... rest of fields and their getters and setters
}
然后,您可以将数据作为实体的实例读取:
@POST
@Path("/test2")
public void test2(@Context HttpServletRequest request) {
...
Response response = client.target("http://ip-api.com/json/" + ip)
.request(MediaType.TEXT_PLAIN_TYPE)
.header("Accept", "application/json").get();
Geolocation location = response.readEntity(Geolocation.class);
response.close();
// now the instance of Geolocation contains all data from the message
}
如果您对获取响应的详细信息不感兴趣,则无法直接从get()
方法获取结果消息:
Geolocation location = client.target("http://ip-api.com/json/" + ip)
.request(MediaType.TEXT_PLAIN_TYPE)
.header("Accept", "application/json").get(Geolocation.class);
// just the same has to work for String

该打印什么? System.out.println("body:" + response.getEntity());
另外,您要用来发布哪些图书馆?那是球衣吗?
