在 shell 脚本中检查 Bitbucket 登录凭据 [英] Check Bitbucket login credentials inside shell script

问题描述

我目前正在编写一个 shell/bash 脚本来自动化工作流程.这个 bash 脚本可以克隆项目并在 Bitbucket 上创建新的 repo，执行 Composer 安装/更新等等.

I'm currently writing a shell/bash script to automate a workflow. This bash script can clone projects and create new repo's on Bitbucket, do composer install/update's and more of that stuff.

我的第一个计划是通过 SSH 完成此操作，但在某些情况下我需要 HTTPS.对于所有认为通过 HTTPS 进行的操作，我需要先检查 Bitbucket 的用户凭据.由用户名和密码组成的凭据.

My first plan was to do this all over SSH, but there are some situations that I need HTTPS. For all thinks that go's over HTTPS I need to check the user credentials for Bitbucket first. The credentials consisting of a username and password.

这可能吗.如果是，怎么办?

Is this possible. If so, how?

推荐答案

正如你在评论中所建议的，curl 可以为你做 HTTP Basic Auth.对于 BitBucket，响应将是 401 Unauthorized 或 200 OK，具体取决于用户名/密码对的有效性.您可以使用 grep 测试输出(或仅标题)，但更强大的方法是使用 -w/--write-out 选项，结合一个 HEAD 请求和 -s 静默输出:

As you suggested in comments, curl can do HTTP Basic Auth for you. For BitBucket, the response will be 401 Unauthorized or 200 OK, depending on the validity of username/password pair. You could test the output (or only headers) with grep, but a little bit more robust approach would be to use the -w/--write-out option, combined with a HEAD request and -silenced output:

http_status=$(curl -X HEAD -s -w '%{http_code}' 
              -u "username:password" -H "Content-Type: application/json" 
              https://api.bitbucket.org/2.0/repositories/$repo_owner)

然后，为了测试状态，您可以使用一个简单的条件表达式:

Then, to test the status, you can use a simple conditional expression:

if [[ $http_status == 200 ]]; then
    echo "Credentials valid"
else
    if [[ $http_status == 401 ]]; then
        echo "Credentials INVALID"
    else
        echo "Unexpected HTTP status code: $http_status"
    fi
fi

或者，如果您计划测试多个状态代码，您可以使用 case 命令，例如:

Or, if you plan on testing multiple status codes, you can use the case command, for example:

case $http_status in
    200) echo "Credentials valid";;
    301|302) echo "API endpoint changed";;
    401) echo "Credentials INVALID";;
    5*) echo "BitBucket Internal server error";;
    *) echo "Unexpected HTTP status code: $http_status";;
