我希望有人可以帮助我间歇性连接我 获得使用code与HttpsURLConnection。在code我使用的是 如下：

I'm hoping someone could help me out with intermittent connections I'm getting using code with HttpsURLConnection. The code I'm using is below:

HttpsURLConnection conn = (HttpsURLConnection) url.openConnection(); conn.setReadTimeout(10 * 1000); if conn.getResponseCode() != 200) { Log.v(TAG, "error code:" + conn.getResponseCode()); }

该连接工作在第一时间每次，当我用它来拉 JSON文件。然而，当我使用的连接再次发送指令， 它总是失败的第一次。然后，它通常工作，如果我送 如果我等一会儿命令迅速（5秒内），但失败。 我不认为它是一个SSL问题，因为它第一次连接 正确的，但我在这里可能是错的。我也尝试过许多不同 的变化，如添加：

The connection works the first time everytime when I use it to pull a json file. However, when I use the connection again to send a command, it always fails the first time. It then typically works if I send the command quickly ( within 5 seconds), but fails if I wait a while. I don't think its a SSL issue because it connects the first time correctly, but I could be wrong here. I also tried many different variations such as adding:

conn.setUseCaches(false); conn.setRequestProperty("Connection","Keep-Alive"); conn.getHostnameVerifier(); conn.getSSLSocketFactory(); conn.setDoOutput(true); conn.setDoInput(true); conn.setRequestMethod("POST"); conn.wait(100);

不过，我没有运气。任何帮助将大大AP preciated。

However, I had no luck. Any help would be greatly appreciated.

推荐答案

尝试 System.setProperty（http.keepAlive，假）; 在此之前

HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
