c - Apache C CGI 程序错误

Question

我正在尝试用 C 语言编写一个 CGI 程序(我正在学习，这似乎是一件有趣的事情)，但我遇到了 Apache/CGI 错误的问题，但仅限于一个非常特定的行。如果这一行被注释或删除，它工作得很好，但如果包含它，它每次都会崩溃。

struct site_link
{
    char *name;
    char *url;
};

struct blog_data
{
    char *blog_name;
    struct site_link *links;
} blog;

blog.blog_name = "richardwagner.io";
blog.links[0].url = "Home"; // <-- this line right here
blog.links[0].name = "Home";
blog.links[1].url = "Posts";
blog.links[1].name = "Posts";
blog.links[2].url = "About";
blog.links[2].name = "About";

并且 Apache 日志的“调试”级别日志记录已打开。

几天来我一直在尝试解决这个问题，但我就是无法让它与这一行很好地配合，尽管对我来说，它看起来与它下面的其他几行几乎相同。

Answer 1

您缺少\r\n\r\n 来表示 header 结束。
