利用gitlab的webhook功能以及jenkins的gitlab hook-plugin和gitlab-plugin插件实现当代码push到gitlab时触发Jenkins自动构建项目操作

Jenkins配置

插件安装

系统管理=====》插件管理=====》可选插件=====》搜索要按照的插件(gitlab hook-plugin和gitlab-plugin)
如果找不到上面两个插件，安装gitlab和gitlab hook即可

创建测试项目

新建项目=====》配置gitlab仓库地址=====》配置构建触发器

gitlab配置

打开要关联Jenkins项目的设置选项找到webhooks选项，把Jenkins中的项目触发器url以及Secret token配置到gitlab的webhooks选项中

URL

Secret token

验证效果

我们测试下点击刚刚关联的构建动作，Jenkins会不会自动构建
当出现请求状态码200的时候证明我们的关联动作已经执行

下面我们去到Jenkins中看下是否有构建历史

再试下手动push代码到gitlab会不会触发Jenkins的构建任务
手动去到服务器上向远程gitlab分支推送文件

这里可以看到Jenkins已经在执行构建操作了！

最后我们再去到Jenkins的中间目录看下刚刚推送的文件是否成功

我们可以看到刚刚变更的文件已经成功存放在Jenkins的中间目录，后续我们可以通过构建后操作将代码推送到我们的服务器

GitLab服务器和Jenkins服务器可以通过Web Hook的方式进行通信。

（1）在Jenkins服务器中，安装GitLab Plugin和GitLab Hook Plugin

（2）打开一个任务配置，构建触发器中选择"Build when a change is pushed to GitLab."记下GitLab webhook URL，使用时候将localhost替换成服务器的ip地址。

（3）在GitLab服务器中，在目标project的Settings -> Integrations中添加Web Hook。将Jenkins产生的GitLab webhook URL填入URL，其他选项使用默认设置，点击"Add webhook"，webhook添加成功：

（4) 点击下方Test，并选择"Push events"，系统报错，有权限问题：Jenkins匿名用户无Build权限。

（5）在Jenkins中修改安全策略（谨慎操作，确保操作用户具有所有权限）：

系统管理 -> 全局安全配置 -> 在安全矩阵中给予匿名用户Build权限

（6）在GitLab中再次测试：

（7) 在配置安全策略过程中出现了服务器访问报错，用户无法登录的情况，具体可参考：

主要思路是：通过修改~/.jenkins/config中authorizationStrategyclass的值（经重启Jenkins服务器生效），逐步改变Jenkins的安全策略，最终恢复正常状态。

1.form表单会自动提交的几种情况

1）表单里有一个type="submit"的按钮，回车键生效

2）表单里只有一个type="text"的input，回车键生效。

2.form表单自动提交的请求

如果form表单没有设置action属性，自动提交的请求是当前页面地址，即页面会自动刷新
