关于Java：忽略Apache HttpClient 4.3中的SSL证书


Ignoring SSL certificate in Apache HttpClient 4.3

如何忽略Apache HttpClient 4.3的SSL证书(全部信任)？

我在SO上找到的所有答案都对待以前的版本，并且API更改了。

有关：

  • 如何忽略Apache HttpClient 4.0中的SSL证书错误
  • 如何使用Apache HttpClient处理无效的SSL证书？
  • 使用Spring开发期间需要信任所有证书
  • 忽略Java的SSL证书错误

编辑：

  • 仅用于测试目的。 孩子们，不要在家(或在生产中)尝试

下面的代码用于信任自签名证书。创建客户端时，必须使用TrustSelfSignedStrategy：

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        builder.build());
CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
        sslsf).build();

HttpGet httpGet = new HttpGet("https://some-server");
CloseableHttpResponse response = httpclient.execute(httpGet);
try {
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
} finally {
    response.close();
}

我没有故意包含SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER：关键是允许使用自签名证书进行测试，因此您不必从证书颁发机构获取适当的证书。您可以轻松创建具有正确主机名的自签名证书，而不要添加SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER标志。

如果您使用上面的PoolingHttpClientConnectionManager过程不起作用，则将忽略自定义SSLContext。创建PoolingHttpClientConnectionManager时，必须在构造函数中传递socketFactoryRegistry。

builder.loadTrustMaterial(null, new TrustStrategy(){

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

而且，如果您也想跳过主机名验证，则需要设置

    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

也一样(不建议使用ALLOW_ALL_HOSTNAME_VERIFIER)。

强制性警告：您不应该这样做，接受所有证书是一件坏事。但是，在某些罕见的用例中，您想这样做。

作为前面给出的代码的注释，即使httpclient.execute()抛出异常，您也希望关闭响应

花瓶的答案的一个小补充：

使用PoolingHttpClientConnectionManager时，SocketFactoryRegistry提供的解决方案可以工作。

但是，通过纯http的连接将不再起作用。您还必须为http协议添加一个PlainConnectionSocketFactory，以使它们再次运行：

Registry<ConnectionSocketFactory> socketFactoryRegistry =
  RegistryBuilder.<ConnectionSocketFactory> create()

更简单，更短的工作代码：

We are using HTTPClient 4.3.5 and we tried almost all solutions exist on the stackoverflow but nothing,
After thinking and figuring out the problem, we come to the following code which works perfectly,
just add it before creating HttpClient instance.

使用http客户端4.5时，我必须使用javasx.net.ssl.HostnameVerifier允许任何主机名(出于测试目的)。这是我最终要做的事情：

(我本来可以直接在vasekt的答案中添加评论，但我的信誉点不足(不确定那里的逻辑)

无论如何...我想说的是，即使您没有显式创建/请求PoolingConnection，也不意味着您没有得到。

我发疯了，试图弄清楚为什么原始解决方案对我不起作用，但是我忽略了vasekt的回答，因为它"不适用于我的情况"-错误！

我低头盯着我的堆栈跟踪，发现中间有一个PoolingConnection。邦-我讨厌他的加入和成功！！ (我们的演示是明天，我感到绝望):-)

您可以使用以下代码片段来获取HttpClient实例，而无需进行ssl认证检查。
