卷曲：为什么我得到空洞的回应？

Question

我使用谷歌开发者工具并将答案复制为卷曲请求

当我在我的linux服务器上运行卷曲时，我得到来自服务器的空回复

curl 'https://web-ast.dsi.cnrs.fr/l3c/owa/personnel.liste?nom=&prenom=&code_labo=&p_dep=52&sec=&bap=&emptype=&nat_pers=&typ_pers=&organisme=&delegation=&ville=&p_i=0&p_nb_res=0' \

curl: (52) Empty reply from server

详细输出：

知道为什么吗？

Answer 1

  

-k，--insecure（SSL）此选项明确允许curl执行“不安全”的SSL连接和传输。通过使用默认安装的CA证书捆绑包，尝试使所有SSL连接安全。这使得所有被认为是“不安全”的连接都会失败，除非使用-k，-insecure。

试试这个兄弟。
