Question

我使用谷歌開發者工具和答案複製爲捲曲請求

當我在我的Linux服務器上運行的捲曲，我從服務器

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' \

任何想法爲什麼？

Answer 1

-k，--insecure（SSL）此選項明確允許curl執行「不安全」SSL連接和傳輸。嘗試使用默認安裝的CA證書包來保證所有SSL連接的安全。這使得所有認爲「不安全」的連接都會失敗，除非使用-k，--insecure。

試試這個兄弟。
