HttpsURLConnection和间歇性连接 [英] HttpsURLConnection and intermittent connections
问题描述
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();
