Jetty Client 实现HTTPS Client（SSL）

写着这篇文章，心里却想着贝叶斯公式，以前就是简单粗暴的计算概率，却忘记了还有先验概率，似然概率，归一化因子来计算：后验概率。

以前项目的接口测试都是基于Http，现在REST接口测试都是基于Https, 所以需要将目前测试代码中Jetty的Client中的HTTP方式改成Https的方式。
查找Jetty的官网 Jetty Http Client Study，里面很清楚的介绍到如何设置HTTPS的请求：

In order to perform HTTPS requests, you should create first a SslContextFactory, configure it, and pass it to the HttpClient constructor. When created with a SslContextFactory, the HttpClient will be able to perform both HTTP and HTTPS requests to any domain.

// Instantiate and configure the SslContextFactory
SslContextFactory sslContextFactory = new SslContextFactory();

// Instantiate HttpClient with the SslContextFactory
HttpClient httpClient = new HttpClient(sslContextFactory);

// Start HttpClient
httpClient.start();

• 如果遇到执行Https Request提示Too Large的错误提示，那么需要设置Request的Buffer大小，默认Request的Buffer大小是4096Bytes, 可以在源码里找到：

private int requestBufferSize = 4096;

所以，需要增加Request的Buffer, 例如：

httpclient.setRequestBufferSize(2*4096);

这里要划下重点！！！

• 如果遇到执行过程里提示“Authentication challenge without WWW-Authenticate header”的错误。
  提示：可以进一步打断点到Jetty的源码，看看底层源码发生了什么错误。最后发现这个错误就是因为Client Request发往Server后，被Server告知401未授权。

服务器会返回一个401 Unauthozied给客户端，并且在Response 的 header "WWW-Authenticate" 中添加信息。

贴下jetty Https的实现

package base;

import org.eclipse.jetty.client.HttpClient;
import org.eclipse.jetty.client.api.ContentResponse;

import org.eclipse.jetty.client.util.BytesContentProvider;
import org.eclipse.jetty.http.HttpMethod;
import org.eclipse.jetty.util.ssl.SslContextFactory;

import java.util.HashMap;


public class HTTPClientRequest {



    public static HashMap RequestToPlatform(String method, String requestBody, String URL) throws Exception{

        String token = PostResult2File.ReadFile("src/test/resources/Readtoken.dat");
        String[] tokenValue = token.split(",");
        HashMap<String,Object> responseMap = new HashMap<>();
        SslContextFactory sslContextFactory = new SslContextFactory();
        sslContextFactory.setTrustAll(false);
        System.setProperty("javax.net.ssl.trustStore","src/test/resources/mg.store");
        HttpClient httpclient = new HttpClient(sslContextFactory);
        //httpclient.setFollowRedirects(false);
        httpclient.setRequestBufferSize(2*4096);
        httpclient.start();
        ContentResponse response = null;
        System.out.println("====Sending Http Request====");
        //add token into header
        if (method.toLowerCase().equals("post") || method.toLowerCase().equals("put")){
            response = httpclient.newRequest(URL).header("Authorization",tokenValue[1]).method(HttpMethod.POST).content(new BytesContentProvider(requestBody.getBytes("UTF-8")),"application/json;charset=UTF-8").send();
            //response = httpclient.newRequest(URL).method(HttpMethod.POST).content(new BytesContentProvider(requestBody.getBytes("UTF-8")),"application/json;charset=UTF-8").send();
            System.out.println(response.getHeaders());

        }
        if (method.toLowerCase().equals("get")){
            response = httpclient.newRequest(URL).header("Authorization",tokenValue[1]).method(HttpMethod.GET).send();
        }
        if(response!=null){
            responseMap.put("ResponseStatus",response.getStatus());
            responseMap.put("ResponseBody", response.getContentAsString());
        }

        return responseMap;
    }

}
