从.NET启动流程，但RedirectedStandardOutput不支持UTF-8 [英] Started Process from .NET but RedirectedStandardOutput doesn't support UTF-8

问题描述

我正在尝试使用以下代码从.NET调用php的HTML净化器:

I am trying to call php's HTML purifier from .NET using this code:

    Process myProcess = new Process();

    myProcess.StartInfo.FileName = "C:\Path\to\php.exe";
    myProcess.StartInfo.Arguments = "C:\Path\to\purify.php";
    myProcess.StartInfo.UseShellExecute = false;
    myProcess.StartInfo.RedirectStandardOutput = true;
    myProcess.StartInfo.RedirectStandardInput = true;

    myProcess.Start();

    StreamWriter myStreamWriter = myProcess.StandardInput;

    String inputText;

    inputText = txtCodes.Text;
    if (inputText.Length > 0)
    {
        myStreamWriter.Write(inputText);
    }
   myStreamWriter.Close();

    labMsg.Text = myProcess.StandardOutput.ReadToEnd();

    myProcess.WaitForExit();

    myProcess.Close();

..，所有工作正常，除了...我无法找回非ASCII字符.例如，在输入中提供一些韩文字符会返回问号作为输出.

.. and all works fine except ... I am not able to get back non-asci characters. For example providing some Korean characters in the input returns questionmarks as output.

即使通过了HTMLPurifier函数，这种情况也会发生，我只是尝试简单地提供输入.NET，将其存储在php变量中，并将该变量回显为输出.

This happens even if the HTMLPurifier function is bypased and I am just trying to simple provide the input .NET, store it in php variable, and echo that variable back to output.

有什么想法吗?

推荐答案

感谢指针.我确实设法解决了.问题是为输入和输出都明确指定UTF-8.最后，唤醒代码如下所示:

Thanks for the pointer. I did actually managed to solve it. The catch was to explicitly specify UTF-8 for BOTH input and Output. In the end the woking code looks like this:

Process myProcess = new Process();

    myProcess.StartInfo.FileName = "C:\Path\to\php.exe";
    myProcess.StartInfo.Arguments = "C:\Path\to\purify.php";

    myProcess.StartInfo.UseShellExecute = false;
    myProcess.StartInfo.RedirectStandardOutput = true;
    myProcess.StartInfo.RedirectStandardInput = true;
    myProcess.StartInfo.StandardOutputEncoding = Encoding.UTF8;

    myProcess.Start();
    StreamWriter myStreamWriter = new StreamWriter(myProcess.StandardInput.BaseStream, Encoding.UTF8);

    String inputText;
    inputText = txtCodes.Text;

    if (inputText.Length > 0)
    {
        myStreamWriter.Write(inputText);
    }

    myStreamWriter.Close();

    labMsg.Text = myProcess.StandardOutput.ReadToEnd();


    myProcess.WaitForExit();

    myProcess.Close();
