HttpClient访问https

哈希塞特 2020-07-13 11:39:49
帮忙看下我这段配置，为什么不能访问https的接口

static {
ConnectionSocketFactory plainsf = PlainConnectionSocketFactory.getSocketFactory();
SSLContext sc;
try {
sc = SSLContext.getInstance("TLS");
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager(){
@Override
public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
}
@Override
public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
} };
sc.init(null, trustAllCerts, null);
} catch (Exception e) {
LOG.error("some thing happen", e);
throw new ServiceException(e);
}
ConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sc, (s, sslSession) -> true);
ConnectionKeepAliveStrategy connectionKeepAliveStrategy = (httpResponse, httpContext) -> {
return 20L * 1000;
};
Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory> create()
.register("http", plainsf).register("ftp", plainsf).register("https", sslsf).build();
PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(registry);
connManager.setMaxTotal(400);
connManager.setDefaultMaxPerRoute(200);
RequestConfig requestConfig = RequestConfig.custom().setConnectTimeout(HTTP_CONNECT_TIME_OUT)
.setConnectionRequestTimeout(3000).setSocketTimeout(HTTP_TIME_OUT).build();
client = HttpClients.custom().setConnectionManager(connManager)
.setRetryHandler(new DefaultHttpRequestRetryHandler()).setDefaultRequestConfig(requestConfig)
.setKeepAliveStrategy(connectionKeepAliveStrategy).build();
}

connect timed out，连接超时 有可能是对方服务的问题，或者端口不通

公司网络使用代理，在dhcp中指定了代理 你的代码没有从系统网络参数中获得代理信息，所以在公司内网无法访问外网

百度上都是这么配的，到我这就不行了。最后返回的client对象按道理应该是能访问https接口的

现在问题是这样，环境是公司内网，本地用其他http工具访问外网https是可以访问的，就是在java代码中不能访问外部https。
然后我把电脑连上我自己的手机热点，其他什么然后代码中也可以访问外部https了。
问题应该是网络原因，但是公司内网中为什么用postman也能访问https呢？

错误信息就是超时，本地用其他http工具调试都没问题
使用httpClient访问https+443端口号。

android HttpClient访问Https
android HttpClient访问某些Https时，出现了问题，无法访问，好像是要安全验证。此Demo解决了此问题，HttpClient能够Https和Http类型的URL了。 在eclipse下打开工程若有乱码，请把eclipse的字符编码改成UTF-8。
HttpClient4.5 实现https忽略SSL证书验证
使用HttpClient4.5实现https请求忽略SSL证书验证工具类
Android使用HttpClient和HttpsUrlConnection两种方式访问https网站
使用httpclient和httpsurlconnection两种方法访问https网址，同时分为验证证书和不验证证书两种方法
httpclient4.5发送https请求（验证证书）
不会的可以在评论区留言哈，这是我自己做项目用到的。所以绝对可用！同时共享出来给到大家
