我使用Google开发人员工具并将答案复制为卷曲请求

I use google developer tool and copy the answer as curl request

当我在linux服务器上运行该curl时，我得到了服务器上的空回复

知道为什么吗？

推荐答案

-k，-不安全（SSL）此选项明确允许curl执行不安全的SSL连接和传输。试图通过使用默认安装的CA证书捆绑包来确保所有SSL连接的安全。除非使用-k，--insecure，否则所有被认为不安全的连接都会失败。

-k, --insecure (SSL) This option explicitly allows curl to perform "insecure" SSL connections and transfers. All SSL connections are attempted to be made secure by using the CA certificate bundle installed by default. This makes all connections considered "insecure" fail unless -k, --insecure is used.

尝试使用此兄弟。
