JAVA - 使用SSL证书和HTTPS的简单GET请求 [英] JAVA - Simple GET request, using SSL certificate and HTTPS

问题描述

我有一个带有'.pfx'扩展名的文件和这个证书的密码。

I have a file with the '.pfx' extension and a password to this certificate.

我需要做的是向一个简单的GET请求发送一个webservice并阅读响应正文。

What I need to do is to send a simple GET request to a webservice and read the response body.

我需要实现类似于此的方法：

I need to implement a method similar to this:

String getHttpResponse(String url, String certificateFile, String passwordToCertificate){
    ...
}

我还尝试使用openssl将证书转换为无密码格式：

I also tried converting the certificate to a format "with no password" using openssl:

Convert a PKCS#12 file (.pfx .p12) containing a private key and certificates to PEM:
openssl pkcs12 -in keyStore.pfx -out keyStore.pem -nodes

所以我方法的替代实现可能是：

So the alternate implementaion of the my method could be:

String getHttpResponse(String url, String certificateFile){
    ...
}

我非常感谢你的帮助，我花了半天时间用Google搜索，但是我还没有找到一个可以帮助我的例子，似乎我遇到了一些关于SSL和东西的一些基本假设的问题。

I would really appreciate your help, I spent half a day googling for it, but I haven't found an example that would help me, it seems I have problems with undestanding some basic assumptions around SSL and stuff.

推荐答案

我终于找到了一个很好的解决方案（没有创建自定义SSL上下文）：

I finally found a good solution (without creating custom SSL context):

String getHttpResponseWithSSL(String url) throws Exception {
    //default truststore parameters
    System.setProperty("javax.net.ssl.trustStore", "/usr/lib/jvm/java-6-openjdk/jre/lib/securitycacerts");
    System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
    System.setProperty("javax.net.ssl.trustStoreType", "JKS");

    //my certificate and password
    System.setProperty("javax.net.ssl.keyStore", "mycert.pfx");
    System.setProperty("javax.net.ssl.keyStorePassword", "mypass");
    System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");


    HttpClient httpclient = new HttpClient();

    GetMethod method = new GetMethod();
    method.setPath(url);

    int statusCode = httpclient.executeMethod(method);
    System.out.println("Status: " + statusCode);

    method.releaseConnection();

    return method.getResponseBodyAsString();
}
