Java 使用 HttpClients 报错

Question

使用HttpClients 请求第三方post接口报错，帮忙看一下如何解决，错误日志如下

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed

代码 ：

```java
HttpPost httpPost = new HttpPost(NanShuoUrlEnum.getUrl(host, NanShuoUrlEnum.GET_TOKEN));
            // 请求参数
            JSONObject data = new JSONObject();
            data.put("userName","apitest");
            data.put("userPwd","123456");
            data.put("phone","18756005448");
            StringEntity entityParams = new StringEntity(data.toString(), "utf-8");
            entityParams.setContentEncoding("UTF-8");
            httpPost.setHeaders(new BasicHeader[]{
                    new BasicHeader("Content-Type", "multipart/form-data")
            });
            httpPost.setEntity(entityParams);

            CloseableHttpClient client = HttpClients.createDefault();
            CloseableHttpResponse httpResponse = client.execute(httpPost); // 这行代码报错
            String json = EntityUtils.toString(httpResponse.getEntity(), "UTF-8");

```

SSL校验失败，看下host是否有效，token是否有效
