推荐答案

为了从您可以使用这样的一个网址让你的源$ C ​​$ C：

In order to get your source code from an URL you can use this :

HttpClient httpclient = new DefaultHttpClient(); // Create HTTP Client
HttpGet httpget = new HttpGet("http://yoururl.com"); // Set the action you want to do
HttpResponse response = httpclient.execute(httpget); // Executeit
HttpEntity entity = response.getEntity(); 
InputStream is = entity.getContent(); // Create an InputStream with the response
BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) // Read line by line
    sb.append(line + "\n");

String resString = sb.toString(); // Result is here

is.close(); // Close the stream

您还可以添加一些PARAMS到HttpClient的管理超时和其他类似的东西。 例如：

You can also add some params to the HttpClient to manage timeout and other stuff like that. Ex :

HttpParams httpParameters = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParameters,3000); // 3s max for connection
HttpConnectionParams.setSoTimeout(httpParameters, 4000); // 4s max to get data
HttpClient httpclient = new DefaultHttpClient(httpParameters);
