我正在测试 android 上的 https 帖子，我有 2 个 android 设备，此代码在我的 2.3 设备上完美运行，但将在我的 4.1 设备中被阻止在“retcode=urlCon.getResponseCode();”，我也检查了数据包嗅探 post 请求已发送并且服务器确实回复了 https 响应，但它仍然被阻止直到超时。
private String GetHttpPage(HttpsURLConnection urlsCon,String host,String url,String reference,boolean type,String curcookie,String postparam){
String query = postparam;
byte[] entitydata = query.getBytes();
String line="";
HttpURLConnection urlCon=urlsCon;
try{
String domain="";
String fullurl=host+url;
if(urlCon==null){
if(host.indexOf("https")!=-1){
urlCon =GetHttpsConnect(fullurl);
domain=host.substring(8);
}
else{
urlCon =GetHttpConnect(fullurl);
domain=host.substring(7);
}
}
urlCon.setConnectTimeout(30000);
urlCon.setReadTimeout(30000);
if(reference!=null)
urlCon.setRequestProperty("Referer", reference);
urlCon.setRequestProperty("Cache-Control", "no-cache");
urlCon.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)");

urlCon.setRequestProperty("Accept-Language", "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3");
urlCon.setRequestProperty("connection", "Keep-Alive");
urlCon.setRequestProperty("Host", domain);
//

urlCon.setRequestProperty("Content-Length",String.valueOf(entitydata.length));
urlCon.setRequestMethod("POST");
}
else{
urlCon.setDoOutput(false);
urlCon.setDoInput(true);
urlCon.setRequestMethod("GET");
}
urlCon.connect();
if(type){
OutputStream outStream = urlCon.getOutputStream();
outStream.write(entitydata, 0, entitydata.length);
// outStream.write(entitydata);
outStream.flush();
outStream.close();
}
retcode=urlCon.getResponseCode();
if(urlCon.getHeaderField("Location")!=null)
redirect=urlCon.getHeaderField("Location");

String tempcookie=svalue;
tempcookie=tempcookie.substring(1, tempcookie.length()-1);
cookie+=ProcessCookie(tempcookie);
//cookie=cookie.substring(0, cookie.length()-2);
}
}

BufferedReader in = new BufferedReader(new InputStreamReader(urlCon.getInputStream()));
String subline="";
