ProcessBuilder类的start方法返回一个表示进程的java.lang.Process类的对象。通过Process类的getOutputStream方法,可以获取用于向进程写入数据的输出流;而通过getInputStream和getErrorStream方法,可以分别获取包含进程正常执行和出错时输出内容的输入流。 创建进程 下面是一个创建进程的示例代码: java 复制代码 public void sta...
描述(Description) java.lang.Process.getErrorStream()方法获取子进程的错误流。 该流获取从此Process对象表示的进程的错误输出流中传输的数据。 声…
import java.io.BufferedReader; import java.io.InputStreamReader; 1. 建立连接并发送请求:使用URL和HttpURLConnection类建立到目标URL的连接。然后,使用getInputStream()或getErrorStream()方法获取服务器的响应。 2. java复制代码 URL url = new URL("https://www.example.com"); HttpURLConnection connection =...
通过getErrorStream()方法获取执行错误的输出流。 读取错误流并输出错误日志。 下面是一个示例代码,演示了如何执行FFmpeg指令并捕获错误日志: importjava.io.BufferedReader;importjava.io.IOException;importjava.io.InputStream;importjava.io.InputStreamReader;publicclassFFmpegErrorExample{publicstaticvoidmain(String[]arg...
publicvirtualSystem.IO.Stream? ErrorStream { [Android.Runtime.Register("getErrorStream","()Ljava/io/InputStream;","GetGetErrorStreamHandler")]get; } Property Value Stream an error stream if any, null if there have been no errors, the connection is not connected or the server sent no useful ...
值得注意的是,上述代码中使用的是connection.getInputStream()方法来获取输入流。如果我们需要获取其他类型的流,如错误流或者输出流,可以使用getErrorStream()和getOutputStream()方法。 总结 通过本文,我们了解了如何使用Java获取远程地址文件的方法,并提供了相应的代码示例。使用URL类和HttpURLConnection类都能够实现这一...
new InputStreamReader(process.getErrorStream())); int data; // Because pin and perr are streams connect to the same process, // so when you read out one staream, the another stream is also closed, // we only can start both reading in a thread Thread errReadThread = new Thread() {...
If the HTTP response indicates that an error occurred, #getInputStream() will throw an IOException. Use #getErrorStream() to read the error response. The headers can be read in the normal way using #getHeaderFields(), <h3>Posting Content</h3> To upload data to a web server, configure the...
aredirectErrorStreamproperty. Initially, this property isfalse, meaning that the standard output and error output of a subprocess are sent to two separate streams, which can be accessed using theProcess.getInputStream()andProcess.getErrorStream()methods. ...
abstractInputStreamgetErrorStream() Returns the input stream connected to the error output of the subprocess. abstractInputStreamgetInputStream() Returns the input stream connected to the normal output of the subprocess. abstractOutputStreamgetOutputStream() ...
