我正在尝试构建Java中对Skyscanner API的请求示例-但我做错了-skyscanner API测试的链接:http://business.skyscanner.net/portal/en-GB/Documentation/FlightsLivePricingQuickStart
这是我到目前为止的测试代码-我收到“内部服务器错误”。
任何人都可以看到此示例中的错误内容吗？
谢谢

最佳答案
我知道这是一个老问题，但是我花了很多时间来找到一个适用于Java的示例，因此我在这里发布了我已经完成的解决方案。我使用了HttpClient和HttpPost类的HttpUrlConnection。
import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.nio.charset.StandardCharsets;
public class FlightsJava {
public static void main(String[] args) throws IOException {
String request = "http://partners.api.skyscanner.net/apiservices/pricing/v1.0/";
URL url = new URL( request );
HttpURLConnection conn= (HttpURLConnection) url.openConnection();
conn.setDoOutput( true );
conn.setInstanceFollowRedirects( false );
conn.setRequestMethod( "POST" );
conn.setRequestProperty( "Content-Type", "application/x-www-form-urlencoded");
conn.setRequestProperty("Accept", "application/json");
conn.setRequestProperty( "charset", "utf-8");
String urlParameters = "apiKey=YOUR_API_KEY&country=BR¤cy=BRL&locale=pt-BR&originplace=SDU&destinationplace=GRU&outbounddate=2016-09-23&locationschema=Iata&adults=1";
byte[] postData = urlParameters.getBytes( StandardCharsets.UTF_8 );
int postDataLength = postData.length;
conn.setRequestProperty( "Content-Length", Integer.toString( postDataLength ));
conn.setUseCaches( false );
try{
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr.write(postData);
wr.flush();
wr.close();
int responseCode = conn.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + urlParameters);
System.out.println("Response Code : " + responseCode);
System.out.println("Header Fields : " + conn.getHeaderFields());
} catch (Exception e){
System.out.println(e);
}
}
}
请记住，为skyscanner提供的apiKey更改“YOUR_API_KEY”。
希望它对任何人有帮助。
