我可以使用 Java 代码执行 Google 搜索吗?例如,如果我搜索“纽约”,它会向我发送以结构化 方式说明所有信息的数据,例如 JSON 或 XML 数据吗?您能否分享代码或给我任何执行此操作的 API?
最佳答案
谷歌知识搜索的示例代码。
使用 https://console.developers.google.com/apis/dashboard 生成 API > 凭据 > 创建凭据 > API key
import java.util.List;
import org.json.simple.parser.JSONParser;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.google.api.client.http.GenericUrl;
import com.google.api.client.http.HttpRequest;
import com.google.api.client.http.HttpRequestFactory;
import com.google.api.client.http.HttpResponse;
import com.google.api.client.http.HttpTransport;

@Service
public class GoogleSearchService {
@Async
public void searchGoogle(List<String> keywords){
try {
ObjectMapper mapper = new ObjectMapper();
HttpTransport httpTransport = new NetHttpTransport();
HttpRequestFactory requestFactory = httpTransport.createRequestFactory();
JSONParser parser = new JSONParser();
GenericUrl url = new GenericUrl("https://kgsearch.googleapis.com/v1/entities:search");
url.put("query", "Kolkata");
url.put("limit", "1");
url.put("indent", "true");
url.put("key", "xxxxxx");
HttpRequest request = requestFactory.buildGetRequest(url);
HttpResponse httpResponse = request.execute();
String responseString = httpResponse.parseAsString();
JsonNode node = mapper.readTree(responseString).get("itemListElement").get(0).get("result");
System.out.println(node.get("name"));
System.out.println(node.get("@type"));
System.out.println(node.get("detailedDescription").get("articleBody"));
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
关于java - 以编程方式使用 Java 的 Google 搜索,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/40181330/
