如何从java执行https GET请求
我编写了一个Java客户机,它执行如何从java执行https GET请求,java,https,get,Java,Https,Get,我编写了一个Java客户机,它执行httpGET请求,没有任何问题。 现在我想修改这个客户端,以便执行httpsGET请求 import org.apache.http.HttpHost; import org.apache.http.auth.AuthScope; import org.apache.http.auth.UsernamePasswordCredentials; import org.apache.http.client.CredentialsProvider; import o
http
GET请求,没有任何问题。
现在我想修改这个客户端,以便执行https
GET请求
import org.apache.http.HttpHost;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.UsernamePasswordCredentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicCredentialsProvider;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
private String executeGet(final String url, String proxy, int port)
throws IOException, RequestUnsuccesfulException, InvalidParameterException {
CloseableHttpClient httpclient = null;
String ret = "";
RequestConfig config;
try {
String hostname = extractHostname(url);
logger.info("Hostname {}", hostname);
HttpHost target = new HttpHost(hostname, 80, null);
HttpHost myProxy = new HttpHost(proxy, port, "http");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
AuthScope.ANY,
new UsernamePasswordCredentials(USERNAME, PASSWORD));
httpclient = HttpClients.custom().setDefaultCredentialsProvider(credsProvider).build();
config = RequestConfig.custom().setProxy(myProxy).build();
HttpGet request = new HttpGet(url);
request.setConfig(config);
CloseableHttpResponse response = httpclient.execute(target, request);
...
我期待一个简单的修改,比如使用HttpsGet
而不是HttpGet
,但是没有可用的HttpsGet
类
为了处理
https
GET请求,修改此方法的最简单方法是什么?这是我用Java编写的快速肮脏的https客户端,它使用BASIC忽略无效证书和身份验证
import java.io.IOException;
import java.net.URL;
import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
public static HttpsURLConnection getConnection(boolean ignoreInvalidCertificate, String user, String pass, HttpRequestMethod httpRequestMethod, URL url) throws KeyManagementException, NoSuchAlgorithmException, IOException{
SSLContext ctx = SSLContext.getInstance("TLS");
if (ignoreInvalidCertificate){
ctx.init(null, new TrustManager[] { new InvalidCertificateTrustManager() }, null);
}
SSLContext.setDefault(ctx);
String authStr = user+":"+pass;
String authEncoded = Base64.encodeBytes(authStr.getBytes());
HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setDoOutput(true);
connection.setRequestProperty("Authorization", "Basic " + authEncoded);
if (ignoreInvalidCertificate){
connection.setHostnameVerifier(new InvalidCertificateHostVerifier());
}
return connection;
}

我开发了一个解决方案,看起来比这里发布的更容易
private String executeGet(final String https_url, final String proxyName, final int port) {
String ret = "";
URL url;
try {
HttpsURLConnection con;
url = new URL(https_url);
if (proxyName.isEmpty()) {
con = (HttpsURLConnection) url.openConnection();
} else {
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyName, port));
con = (HttpsURLConnection) url.openConnection(proxy);
Authenticator authenticator = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return (new PasswordAuthentication(USERNAME, PASSWORD.toCharArray()));
}
};
Authenticator.setDefault(authenticator);
}
ret = getContent(con);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return ret;
}
您能否澄清getContent方法属于哪个类,因为我得到了错误。URL.getContent()是openConnection()的快捷方式。getContent()因此我们需要查看URLConnection的文档。getContent()粘贴完全工作的代码段是明智的,而不是一些没有导入的代码。
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.X509TrustManager;
/**
* ignore invalid Https certificate from OPAM
* <p>see http://javaskeleton.blogspot.com.br/2011/01/avoiding-sunsecurityvalidatorvalidatore.html
*/
public class InvalidCertificateTrustManager implements X509TrustManager{
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
@Override
public void checkServerTrusted(X509Certificate[] paramArrayOfX509Certificate, String paramString) throws CertificateException {
}
@Override
public void checkClientTrusted(X509Certificate[] paramArrayOfX509Certificate, String paramString) throws CertificateException {
}
}
InputStream content = (InputStream) connection.getInputStream();
private String executeGet(final String https_url, final String proxyName, final int port) {
String ret = "";
URL url;
try {
HttpsURLConnection con;
url = new URL(https_url);
if (proxyName.isEmpty()) {
con = (HttpsURLConnection) url.openConnection();
} else {
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyName, port));
con = (HttpsURLConnection) url.openConnection(proxy);
Authenticator authenticator = new Authenticator() {
public PasswordAuthentication getPasswordAuthentication() {
return (new PasswordAuthentication(USERNAME, PASSWORD.toCharArray()));
}
};
Authenticator.setDefault(authenticator);
}
ret = getContent(con);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return ret;
}
