Question

我的应用程序需要能够发布到https并保留使用cookie创建的会话。到目前为止，我有几种不同的方法来尝试这个问题，但没有一种方法可行。目前我正在研究使用DefaultHttpClient，因为它应该自动保留使用cookie创建的会话。这样可以省去阅读cookie和提交其他帖子的痛苦。但是，当我尝试使用我的代码发布时，帖子失败并出现下面列出的证书错误。

我之前遇到过此证书错误的另一种方式是我尝试解决问题并使其与HttpsURLConnection一起使用，但这并不会自动保留带有Cookie的会话。

有人可以看看我的代码并告诉我我做错了什么，我能做得更好以及需要改变什么才能让它发挥作用。谢谢！！

我一直试图解决这个问题几天，我知道在哪里。每次我进一步深入，我都会被推回去。有人可以帮助我！ =）

Answer 1

此问题是由于客户端应用程序无法验证从信任锚（根受信任的证书颁发机构）和SSL服务器证书构建证书路径。因此，此证书不受信任，SSL握手失败。

apache HTTPClient API提供了一个很好的功能，可以帮助您。 SSLSocketFactory构造函数can take a KeyStore parameter包含受信任的证书。

然后你可以：

创建KeyStore keytool，KeyStore直接包含根CA证书或服务器证书。
将此密钥库添加到您的应用程序
使用此{{1}}

DefaultHttpClient，证书，Https和发布问题！
