为了针对Docker中的 Gitlab实例测试命令行工具,我想使用用户名和密码登录Gitlab并获取创建的会话以验证我的API请求.

因此我会做以下事情：

>使用curl -i http：// localhost：8080 / users / sign_in -s卷曲用户登录页面
>从标题中获取_gitlab_session
>从登录表单中获取authenticity_token
>发送第二个卷曲请求

curl 'http://localhost:8080/users/sign_in' 
  -H "_gitlab_session=${cookie}" 
  -H 'Origin: http://localhost:8080' 
  -H 'Content-Type: application/x-www-form-urlencoded' 
  -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8' 
  -H 'Referer: http://localhost:8080/users/sign_in' 
  -H 'Connection: keep-alive' 
  --data-urlencode "authenticity_token=${token}" 
  --data-urlencode "user[login]=root" 
  --data-urlencode "user[password]=12341234" 
  --data-urlencode "user[remember_me]=0"

但是,我获得了一个而不是有效的用户登录

422 - The change you requested was rejected.

在日志文件中,我看到了

我假设我忘了在第二次请求中传递必要的成分 – 但我无法弄清楚,哪一个.

解决方法

通过其他答案和评论的一些有用提示,我终于想出了这个解决方案：

gitlab_host="http://localhost:8080"
gitlab_user="root"
gitlab_password="12341234"

# curl for the login page to get a session cookie and the sources with the auth tokens
body_header=$(curl -c cookies.txt -i "${gitlab_host}/users/sign_in" -s)

# grep the auth token for the user login for
#   not sure whether another token on the page will work,too - there are 3 of them
csrf_token=$(echo $body_header | perl -ne 'print "$1n" if /new_user.*?authenticity_token"[[:blank:]]value="(.+?)"/' | sed -n 1p)

# send login credentials with curl,using cookies and token from previous request
curl -b cookies.txt -c cookies.txt -i "${gitlab_host}/users/sign_in" 
    --data "user[login]=${gitlab_user}&user[password]=${gitlab_password}" 
    --data-urlencode "authenticity_token=${csrf_token}"

# send curl GET request to personal access token page to get auth token
body_header=$(curl -H 'user-agent: curl' -b cookies.txt -i "${gitlab_host}/profile/personal_access_tokens" -s)
csrf_token=$(echo $body_header | perl -ne 'print "$1n" if /authenticity_token"[[:blank:]]value="(.+?)"/' | sed -n 1p)

# curl POST request to send the "generate personal access token form"
# the response will be a redirect,so we have to follow using `-L`
body_header=$(curl -L -b cookies.txt "${gitlab_host}/profile/personal_access_tokens" 
    --data-urlencode "authenticity_token=${csrf_token}" 
    --data 'personal_access_token[name]=golab-generated&personal_access_token[expires_at]=&personal_access_token[scopes][]=api')

# Scrape the personal access token from the response HTML
personal_access_token=$(echo $body_header | perl -ne 'print "$1n" if /created-personal-access-token"[[:blank:]]value="(.+?)"/' | sed -n 1p)

根据GitLab API documentation,您现在可以使用会话cookie来验证API请求：

curl --header "Private-Token: ${personal_access_token}" https://gitlab.example.com/api/v4/projects

一些提示：

>我首先对curl -c文件(从头文件读取cookie并将其写入文件)与curl -b文件(使用文件中的cookie并随请求发送)混淆
>不幸的是我没有找到与sed一起工作的正则表达式,所以我必须在这里使用perl.
>使用Chrome中的开发者控制台并将POST请求复制为curl命令非常有用：https://www.alexkras.com/copy-any-api-call-as-curl-request-with-chrome-developer-tools/
