本文介绍了Java中的Skyscanner API示例的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我试图在Java中建立一个Skyscanner API请求示例 - 但我做了一些错误的事情 - 用于skyscanner API测试的链接：这里是我到目前为止的测试代码 - 我得到一个内部服务器错误。
任何人都可以在这个例子中看到什么是不正确的？
谢谢

解决方案
我知道这是一个老问题，但我花了很多时间来找到一个适用于Java的示例，所以我在这里发布了我所做的解决方案。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;
导入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 =新的URL（请求）;
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 =国际航空运输协会&安培;成人= 1\" ;
byte [] postData = urlParameters.getBytes（StandardCharsets.UTF_8）;
int postDataLength = postData.length;
conn.setRequestProperty（Content-Length，Integer.toString（postDataLength））;
conn.setUseCaches（false）;
尝试{
DataOutputStream wr = new DataOutputStream（conn.getOutputStream（））;
wr.write（postData）;
wr.flush（）;
wr.close（）;
int responseCode = conn.getResponseCode（）;
System.out.println（\\\
发送'POST'请求到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）;
}
}
}
请记得更改YOUR_API_KEY您的apiKey由skyscanner提供。
希望对任何人都有帮助。
I am trying to build an example of request for Skyscanner API in Java - but I am doing something wrong - the link for skyscanner API test: http://business.skyscanner.net/portal/en-GB/Documentation/FlightsLivePricingQuickStart
Here is the test code I have so far - I get an "Internal Server Error".
Anyone can see what is incorrect in this example?
Thanks

解决方案
I know it's an old question but I spent a lot of time to find an example that works in Java so I post here the solution that I've done. I used the HttpUrlConnection insted of the HttpClient and HttpPost classes.
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);
}
}
}
Remember to change "YOUR_API_KEY" for your apiKey provided by skyscanner.
Hope it helps to anyone.
