当我使用用户名和密码手动sftp时,它工作正常,使用curl时失败。相同的脚本将成功连接到其他服务器没有问题。因为我可以手动登录而其他客户没有问题,服务器管理员也没什么帮助。

这是卷曲失败的尝试:

curl -v --insecure --user username:password sftp://someurl.com

* Connected to someurl.com (199.187.***.***) port 22 (#0)

以下是另一个网址的卷曲成功:

curl --insecure -v sftp://username:password@anotherurl.com

以下是对原始网址的手动尝试:

我们将非常感谢那些比我聪明的人提供的任何帮助。

答案 0 :(得分:3)

让它工作,结果很简单,但只能使用网址中的用户名和密码。

curl -v --insecure sftp://username:urlencodedPassword@somedomain.com

这不起作用。

curl -v --insecure --user username:urlencodedPassword sftp://somedomain.com

比我更了解的人可能会详细说明为什么第二个人不会工作。

感谢和进行公钥身份验证:

curl -v -k --pubkey ~/.ssh/id_rsa.pub sftp://username@host/
