java使用httpclient访问https的get接口并通过cookie传参实现鉴权

1. 首先在浏览器访问登录相关网站，获取到登录后的cookie，例：

2. 通过postman验证cookie能否实现网站鉴权

正常不传cookie的话会出现401报错，提示需要登录才能访问接口

也获取不到cookie数据：

传cookie后，可得到接口数据：

可以在cookie记录中看到网站的cookie值：

注意：传参名称为Cookie，值格式为cookie名称=cookie值，来着这里

3. 代码实现

3.1 引入依赖包

<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpclient</artifactId>
		</dependency>
		<dependency>
			<groupId>org.apache.httpcomponents</groupId>
			<artifactId>httpmime</artifactId>
		</dependency>

3.2 解决访问https问题

SSLClient.java

package com.cnki.base.utils;

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;

public class SSLClient extends DefaultHttpClient {
    public SSLClient() throws Exception{
        super();
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] chain,
                                           String authType) throws CertificateException {
            }
            @Override
            public void checkServerTrusted(X509Certificate[] chain,
                                           String authType) throws CertificateException {
            }
            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        ctx.init(null, new TrustManager[]{tm}, null);
        SSLSocketFactory ssf = new SSLSocketFactory(ctx,SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = this.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", 443, ssf));
    }
}

3.3 解决cookie传参问题

public static String doGet(String url,String charset) throws Exception{
        HttpClient httpClient = null;
        HttpGet httpGet = null;
        String result = null;
        //解决https访问
        httpClient = new SSLClient();
        httpGet = new HttpGet(url);
        Map<String, String> headMap = new HashMap<>();
        headMap.put("Content-Type", "application/json");
        //解决cookie传参
        String cookies = "symphony=b1d0d1ad98acdd5d7d846d4359048a923f932962125e7ad0c9db814d5942879467b648f693d6a11336bcaa8b1bee42090ae1061a025b6f16d8afdc6baac0c1129f62ce384f54ec3360273c1f53642ade6c02274317f2a0d3b8e8cc595d6c53c192ffd19a4884886efab2e7464b9ab71d3dc5d20ead8376e85f58003ad4970b25b6a66e42979b7d00fe0e025216f0aa80022eab08fca5700a7d78b0c891c3abbf8e2c8d1cef2fa81ae3991e267f9b3a8ab3c458077fe72cd7fc7403ef494f25dae5a7dab90ccae4ad4dad276fc0f0dd74c62516f9362c58fc1898491e39daca143340f8f66694422f58a3ab477aefb8ae";
        httpGet.addHeader(new BasicHeader("Cookie", cookies));
        //配置自定义UA
        httpGet.setHeader("User-Agent","Mozilla/5.0(Windows NT 6.1;Win64; x64; rv:50.0) Gecko/20100101 Firefox/50.0");
        setGetHead(httpGet, headMap);
        HttpResponse response = httpClient.execute(httpGet);
        if(response != null){
            HttpEntity resEntity = response.getEntity();
            if(resEntity != null){
                result = EntityUtils.toString(resEntity,charset);
            }
        }
        return result;
    }
