本文介绍了如何做到从Android的一个HTTPS POST？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想做一个HTTPS POST方法，从我的Android应用程序发送一些数据到我的网站。
我用的HttpURLConnection 第一，它的正常工作与我的HTTP URL。我制作的网站是HTTPS和我想用 HttpsURLConnection 发送同一职位。有人可以帮助我使用类是否正确？
我发现了一些源在此链接：
密钥库的keyStore = ...;
的TrustManagerFactory TMF = TrustManagerFactory.getInstance（X509）;
tmf.init（的keyStore）;
的SSL连接上下文= SSLContext.getInstance（TLS）;
context.init（空，tmf.getTrustManagers（），NULL）;
网址URL =新的URL（https://www.example.com/）;
HttpsURLConnection的URLConnection =（HttpsURLConnection）
url.openConnection（）;
urlConnection.setSSLSocketFactory（context.getSocketFactory（））;
在的InputStream = urlConnection.getInputStream（）;
应该是什么密钥库密钥库的价值= ...;
我试着用同样的的HttpURLConnection 发送数据，但我看到一些POST数据遗漏或错误。
我试着从方法<一href="http://stackoverflow.com/questions/11218022/android-https-post-to-bitbucket-issue-tracker-returns-filenotfoundexception?rq=1">this问题。我在下面粘贴
我的code 字符串urlParameters =日期时间=+ URLEn coder.en code（日期时间，UTF-8）+

网址URL =新的URL（myurl）;
HttpsURLConnection康涅狄格州;
康恩=（HttpsURLConnection）url.openConnection（）;
//创建SSL连接
的SSLContext SC;
SC = SSLContext.getInstance（TLS）;
sc.init（NULL，NULL，新java.security.SecureRandom中的（））;
conn.setSSLSocketFactory（sc.getSocketFactory（））;
conn.setConnectTimeout（HTTP_CONNECT_TIME_OUT）;
conn.setReadTimeout（HTTP_READ_TIME_OUT）;
//输出设置为true，表示你是输出（上传）POST数据
conn.setDoOutput（真正的）;
//一旦你设置输出为真，你并不需要设置请求方法来发布，但我这样做也无妨
conn.setRequestMethod（POST）;
conn.setFixedLengthStreamingMode（urlParameters.getBytes（）的长度。）;
conn.setRequestProperty（内容类型，应用程序/ x-WWW的形式urlen codeD）;
PrintWriter的输出=的新PrintWriter（conn.getOutputStream（））;
的out.print（urlParameters）;
out.close（）;
InputStream的是= conn.getInputStream（）;
的BufferedReader在=新的BufferedReader（新InputStreamReader的（是））;
字符串inputLine;
而（（inputLine = in.readLine（））！= NULL）{
响应+ = inputLine;
}
我得到的错误是如下：

解决方案
您可以使用在Android设备中定义的默认的CA，这是蛮好的任何公共网站。
如果你有一个自签名的证书，您可以接受所有证书（有风险的，开放的人在这方面的中间人攻击）或创建自己的的TrustManagerFactory ，这是一个有点超出这个范围。
下面是一些code使用默认的CA为HTTPS POST电话：
私人的InputStream的getInputStream（字符串urlStr，用户字符串，字符串密码）抛出IOException异常
{
网址URL =新的URL（urlStr）;
HttpsURLConnection康恩=（HttpsURLConnection）url.openConnection（）;
//创建SSL连接
的SSLContext SC;
SC = SSLContext.getInstance（TLS）;
sc.init（NULL，NULL，新java.security.SecureRandom中的（））;
conn.setSSLSocketFactory（sc.getSocketFactory（））;
//使用这个，如果你需要的SSL认证
串为userpass =用户+：+密码;
字符串BASICAUTH =基本+ Base64.en codeToString（userpass.getBytes（），Base64.DEFAULT）;
conn.setRequestProperty（授权，BASICAUTH）;
//设置超时和方法
conn.setReadTimeout（7000）;
conn.setConnectTimeout（7000）;
conn.setRequestMethod（POST）;
conn.setDoInput（真正的）;
//添加你要张贴在这里的任何数据
conn.connect（）;
返回conn.getInputStream（）;
}
要读取响应：
字符串结果=新的String（）;
InputStream的是=的getInputStream（urlStr，用户名，密码）;
的BufferedReader在=新的BufferedReader（新InputStreamReader的（是））;
字符串inputLine;
而（（inputLine = in.readLine（））！= NULL）{
结果+ = inputLine;
}
I want to do a HTTPS post method to send some data from my android app to my website.
I used HttpURLConnection first and it's working fine with my HTTP URL. My production website is on HTTPS and I want to send the same POST using HttpsURLConnection. Can someone help me use the class properly?
I found some source at this link:
KeyStore keyStore = ...;
TrustManagerFactory tmf = TrustManagerFactory.getInstance("X509");
tmf.init(keyStore);
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
URL url = new URL("https://www.example.com/");
HttpsURLConnection urlConnection = (HttpsURLConnection)
url.openConnection();
urlConnection.setSSLSocketFactory(context.getSocketFactory());
InputStream in = urlConnection.getInputStream();
What should be the value of KeyStore keyStore = ...;?
I tried sending the data using the same HttpURLConnection, but I am seeing some POST data is missed or in error.
I've tried the method from this question. I am pasting my code below
String urlParameters="dateTime=" + URLEncoder.encode(dateTime,"UTF-8")+
"&mobileNum="+URLEncoder.encode(mobileNum,"UTF-8");
URL url = new URL(myurl);
HttpsURLConnection conn;
conn=(HttpsURLConnection)url.openConnection();
// Create the SSL connection
SSLContext sc;
sc = SSLContext.getInstance("TLS");
sc.init(null, null, new java.security.SecureRandom());
conn.setSSLSocketFactory(sc.getSocketFactory());
conn.setConnectTimeout(HTTP_CONNECT_TIME_OUT);
conn.setReadTimeout(HTTP_READ_TIME_OUT);
//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(urlParameters.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(urlParameters);
out.close();
InputStream is = conn.getInputStream();
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String inputLine;
while ((inputLine = in.readLine()) != null) {
response += inputLine;
}
The error I am getting is below:
05-12 19:36:10.758: W/System.err(1123): java.io.FileNotFoundException: https://www.myurl.com/fms/test

解决方案
You can use the default CAs that are defined in the android device, which is just fine for any public web.
If you have a self-signed certificate, you can either accept all certificates (risky, open to man-in-the-middle attacks) or create your own TrustManagerFactory, which is a bit out of this scope.
Here's some code to use the default CAs for a https POST call:
private InputStream getInputStream(String urlStr, String user, String password) throws IOException
{
URL url = new URL(urlStr);
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
// Create the SSL connection
SSLContext sc;
sc = SSLContext.getInstance("TLS");
sc.init(null, null, new java.security.SecureRandom());
conn.setSSLSocketFactory(sc.getSocketFactory());
// Use this if you need SSL authentication
String userpass = user + ":" + password;
String basicAuth = "Basic " + Base64.encodeToString(userpass.getBytes(), Base64.DEFAULT);
conn.setRequestProperty("Authorization", basicAuth);
// set Timeout and method
conn.setReadTimeout(7000);
conn.setConnectTimeout(7000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
// Add any data you wish to post here
conn.connect();
return conn.getInputStream();
}
To read the response:
String result = new String();
InputStream is = getInputStream(urlStr, user, password);
BufferedReader in = new BufferedReader(new InputStreamReader(is));
String inputLine;
while ((inputLine = in.readLine()) != null) {
result += inputLine;
}
