如何更改用 c 创建和编写的 .html 文件中的一行?

How to change a line in my .html file which created and written in c?

我使用了这个 -> fprintf(file, "\r\n"); 但没有换行。

我有一个用 c 语言编写的网络服务器。连接后,我创建了一个 html 文件,内容如下:

This file was saved at :Fri Apr 19 00:49:43 2019 (line break!)
Please click here.

代码:

file = fopen("testvideo.html", "w");

if (file == NULL)
{
    /* File not created hence exit */
    printf("Unable to create file.\n");
    exit(EXIT_FAILURE);
}


time(&tv);
timestr = ctime(&tv);
fprintf(file, "<html> The file was saved at:</html>");
fprintf(file, timestr);
fprintf(file, "\r\n");
fprintf(file,"<html> Please click :<a href=\"http://whatevevevever.com/testvideo.mp3\"\>HERE<a></html>");
fclose(file);

你这里有两个问题,其中一个绝对是关键:

  1. 在 HTML 中换行符是 <br> 而不是 \r\n
  2. 您的 HTML 不正确(或无效)。我不会在这里提供 HTML 教程,但您需要为您的 HTML 使用正确的结构,以确保浏览器能够正确呈现它。

更正后的代码:

if (file == NULL)
{
    /* File not created hence exit */
    printf("Unable to create file.\n");
    exit(EXIT_FAILURE);
}


time(&tv);
timestr = ctime(&tv);
fprintf(file, "<html> <body>The file was saved at:");
fprintf(file, timestr);
fprintf(file, "<br>Please click :<a href=\"http://whatevevevever.com/testvideo.mp3\"\>HERE<a></body></html>");
fclose(file);
