[英]Android/Eclipse Open a file Outside the MainActivity in a Plugin
I have a problem with my Android Phonegap App. 我的Android Phonegap应用程序有问题。
I created a plugin to send Data from HTML/JAVASCRIPT to Java and Java will send this DATA to a Server with HTTPS post. 我创建了一个插件,用于将数据从HTML / JAVASCRIPT发送到Java,Java将通过HTTPS发布将该数据发送到服务器。
To get this Worke I need to Open a ssl.crt (certification) from my Asset folder. 要获得此Worke,我需要从我的Asset文件夹中打开ssl.crt(证书)。
In the Cordova Class this function dose work because it extends the CordovaActivity. 在Cordova类中,此功能有效,因为它扩展了CordovaActivity。
My Plugin Class : public class ConnectPlugin extends CordovaPlugin 我的插件课程:公共课程ConnectPlugin扩展了CordovaPlugin
Here is the Login method: 这是登录方法:
protected String tryLogin_2(String d1) throws CertificateException, FileNotFoundException, IOException, KeyStoreException, NoSuchAlgorithmException, KeyManagementException
{
// Load CAs from an InputStream
// (could be from a resource or ByteArrayInputStream or ...)
CertificateFactory cf = CertificateFactory.getInstance("X.509");
// From https://www.washington.edu/itconnect/security/ca/load-der.crt
InputStream caInput = new BufferedInputStream(this.getAssets().open("ssl.crt"));
java.security.cert.Certificate ca;
try {
ca = cf.generateCertificate(caInput);
} finally {
caInput.close();
}
// Create a KeyStore containing our trusted CAs
String keyStoreType = KeyStore.getDefaultType();
KeyStore keyStore = KeyStore.getInstance(keyStoreType);
keyStore.load(null, null);
keyStore.setCertificateEntry("ca", ca);
// Create a TrustManager that trusts the CAs in our KeyStore
String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
tmf.init(keyStore);
// Create an SSLContext that uses our TrustManager
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
String httpsURL = "https://URL.com";
OutputStreamWriter request = null;
DataInputStream response_2 = null;
String parameters = "1="+d1;
String response = null;
try
{
URL myurl = new URL(httpsURL);
HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection();
con.setSSLSocketFactory(context.getSocketFactory());
con.setRequestMethod("POST");
con.setRequestProperty("Content-length", String.valueOf(query.length()));
con.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
con.setDoOutput(true);
con.setDoInput(true);
request = new OutputStreamWriter(con.getOutputStream());
request.write(parameters);
request.flush();
request.close();
String line = "";
InputStreamReader isr = new InputStreamReader(con.getInputStream());
BufferedReader reader = new BufferedReader(isr);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
//Response from server after login process will be stored in response variable.
response = sb.toString();
isr.close();
reader.close();
}
catch(IOException e)
{
response = "Error"; // Error
}
return response;
}
The problem now is "The method getAssets() is undefined for the type ConnectPlugin". 现在的问题是“类型ConnectPlugin的方法getAssets()未定义”。
I can't use the getAssets() method outside the Main Class. 我不能在Main Class外使用getAssets()方法。 In my MainClass the obove code work 100% fine and sends a request to my server.
在我的MainClass中,过时的代码可以100%正常工作并将请求发送到我的服务器。 But not in my Plugin Class.
但不在我的插件类中。
采用
cordova.getActivity().getAssets().open("ssl.crt"));
