Java使用HttpClient免证书去调用https的方案

一、依赖引入

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.7</version>
</dependency>

二、使用HttpClient跳过证书验证，主要是在构建HttpClient对象时。需要添加SSLContext与SSLConnectionSocketFactory配置.核心代码如下：

    private CloseableHttpClient createHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        SSLContext sslcontext = SSLContexts.custom()
                .loadTrustMaterial(null, (chain, authType) -> true)
                .build();

        SSLConnectionSocketFactory sslSf = new SSLConnectionSocketFactory(sslcontext, null, null,
                new NoopHostnameVerifier());

        return HttpClients.custom().setSSLSocketFactory(sslSf).build();
    }
