问题 I have a web service (.svc), and I am trying to capture the SOAP request using a piece of code found elsewhere on StackOverflow. The problem is that HttpContext.Current is null, so I can't access Request.InputString . Why is this null, and how can it be solved? XmlDocument xmlSoapRequest = new XmlDocument(); Stream receiveStream = HttpContext.Current.Request.InputStream; receiveStream.Position = 0; using (StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8)) {

问题 This may sound very easy or an old stupid question, but it is quite different for me. I have written a Program for a half-Descending pyramid Pattern which is like this. 1 1 2 1 2 3 1 2 3 4 1 2 3 4 5 I know this is very easy, the trick is I don't wanna do this by use of Scanner and Integer.parseInt() . I am trying to do this with BufferedReader and InputStreamReader . So when I execute the following code of my main method with a input of 5 in num. It reads it as 53 when I print it. I have no

问题 Not sure about how I am supposed to do this. Any help would be appreciated 回答1: Read from input stream and write to a ByteArrayOutputStream, then call its toByteArray() to obtain the byte array. Create a ByteArrayInputStream around the byte array to read from it. Here's a quick test: import java.io.*; public class Test { public static void main(String[] arg) throws Throwable { File f = new File(arg[0]); InputStream in = new FileInputStream(f); byte[] buff = new byte[8000]; int bytesRead = 0;

问题 I need to read in a .txt file into a groovy class in order to interrogate it line by line. But I am not sure what folder I put it into in my grails app, and how to get the path to it? So far I have tried placing it under src and also in a new folder web-app/txt and I have tried the the following to read it in fileIn = new File('/lexicon.txt').text and fileIn = new File('txt/lexicon.txt').text to no avail.

问题 I'm trying to read items from a socket and I notice that if there is nothing on the stream of the socket it will stay at the read and back up my application. I wanted to know if there was a way to set a read timeout or terminate the connection after a certain amount of time of nothing in the socket. 回答1: If you write Java, learning to navigate the API documentation is helpful. In the case of a socket read, you can set the timeout option. 回答2: If this socket was created through a URLConnection

问题 I am trying to log the contents of an http request, using an IHttpModule like so: public class LoggingModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += ContextBeginRequest; } private void ContextBeginRequest(object sender, EventArgs e) { var request = ((HttpApplication)sender).Request; string content; using (var reader = new StreamReader(request.InputStream)) { content = reader.ReadToEnd(); } LogRequest(content) } } The problem is that after reading

问题 I know how to read a file by bytes but cannot find a example how to read it in chunks of bytes. I have a byte array, and i want to read the file by 512bytes and send them over a socket. I have tried by reading total bytes of file and then subtracting 512 bytes until i got a chunk that was less than 512 bytes and signaled EOF and end of transfer. I am trying to implement a TFTP, where data is sent in 512 byte chunks. Anyhow would be thankful for a example. 回答1: You ... read 512 bytes at a time
