Vala 如何将结果 file.read 发送到 html

Question

我想知道是否有人可以指导我如何将 glib.file.read 动作的结果发送到 html。

示例我想读取文件 string.txt

File file = File.new_for_path ("string.txt");
try {
    FileInputStream @is = file.read ();
    DataInputStream dis = new DataInputStream (@is);
    string line;

    while ((line = dis.read_line ()) != null) {
        stdout.printf ("%s\n", line);
    }
} catch (Error e) {
    stdout.printf ("Error: %s\n", e.message);
}

return 0;

我希望将这篇散文的结果发布到文件 html，例如 index.html

我们将不胜感激。谢谢

这是一个简短的示例，说明如何将数据写入从GNOME Wiki 获取的文件（您可以在其中找到更多信息）

// an output file in the current working directory
var file = File.new_for_path ("index.html");

// creating a file and a DataOutputStream to the file
var dos = new DataOutputStream (file.create
    (FileCreateFlags.REPLACE_DESTINATION));

// writing a short string to the stream
dos.put_string ("this is the first line\n");

因此您必须创建输出文件并为其创建 DataOutputStream，然后更改循环以将 "string.txt" 的数据写入 "index.html"。最后，它看起来像这样：

public static int main (string[] args) {
    File in_file = File.new_for_path ("string.txt");
    File out_file = File.new_for_path ("index.html");

    // delete the output file if it already exists (won't work otherwise if
    // it does)
    if (out_file.query_exists ()) {
        try {
            out_file.delete ();
        } catch (Error e) {
        stdout.printf ("Error: %s\n", e.message);
        }
    }

    try {
        // create your data input and output streams
        DataInputStream dis = new DataInputStream (in_file.read ());
        DataOutputStream dos = new DataOutputStream (out_file.create
            (FileCreateFlags.REPLACE_DESTINATION));

        string line;

        // write the data from string.txt to index.html line per line
        while ((line = dis.read_line ()) != null) {
            // you need to add a linebreak ("\n")
            dos.put_string (line+"\n");
        }
    } catch (Error e) {
        stdout.printf ("Error: %s\n", e.message);
    }
    return 0;
}
