如何使用blackbox-export监控带账号密码认证的service服务 about prometheus-book

[yunlzheng]

原生支持的http_basic认证，如下：

http_basic_auth_example:
    prober: http
    timeout: 5s
    http:
      method: POST
      headers:
        Host: "login.example.com"
      basic_auth:
        username: "username"
        password: "mysecret"

如果不支持http basic，也可以考虑在headers中传递token之类的方式。

我的blackbox.yml的配置：如下

modules: 
  http_basic_auth_eureka:
    prober: http
    timeout: 50s
    http:
      preferred_ip_protocol: "ip4"
      #valid_status_codes: [200,301]
      method: POST
      headers:
        Host: "192.168.11:11:8888"
        Cache-Control: no-cache
        #Content-Type: application/xhtml+xml
        Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
      basic_auth:
        username: 'eureka'
        password: '********'

浏览器输入http://192.168.11.10:9115/probe?module=http_basic_auth_eureka&target=192.168.11.11:8888&debug=true
返回的结果

返回的http code 为400，我的username和password是正确了，那里出问题了？大佬

并没返回403的错误码，400是Bad Request。 检查一下你服务的日志呢
