Java中的Skyscanner API示例

我正在尝试构建一个Java中Skyscanner API请求的示例 – 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 – 我得到一个“内部服务器错误”。

任何人都可以看到这个例子中的错误？

谢谢

我知道这是一个老问题，但我花了很多时间找到一个适用于Java的示例，所以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&currency=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”。

希望它对任何人都有帮助。
