调试http post请求ansible

Question

我的 ansible playbook 中有以下任务：

    - name: Generate vault token
      uri:
        url: "{{vault_address}}/v1/auth/github/login"
        method: POST
        body: "{ \"token\": \"{{ token }}\" }"
        validate_certs: no
        body_format: json
      register: vault_token

    - name: debug vault
      debug:
        msg: "{{vault_address}}/v1/{{vault_path}}/db2w-flex/{{region_name}}"

    - name: Create secret in vault
      uri:
        url: "{{vault_address}}/v1/{{vault_path}}/db2w-flex/{{region_name}}"
        method: POST
        body: '{ "secret_access_key": "{{ (new_access_key.stdout |from_json).AccessKey.SecretAccessKey }}", "access_key_id": "{{ (new_access_key.stdout |from_json).AccessKey.AccessKeyId }}" }'
        validate_certs: no
        status_code: 204
        headers:
          X-VAULT-TOKEN: '{{ vault_token.json.auth.client_token }}'
        body_format: json        

此任务一直失败：

fatal: [localhost]: FAILED! => {"cache_control": "no-store", "changed": false, "content": "{\"errors\":[\"missing client token\"]}\n", "content_length": "36", "content_type": "application/json", "date": "Tue, 02 Apr 2019 20:16:03 GMT", "failed": true, "json": {"errors": ["missing client token"]}, "msg": "Status code was not [204]", "redirected": false, "status": 400}

相同的任务在另一台主机（kubernetes POD）上运行良好。我在一个新系统（docker容器）上运行它。客户端令牌已正确生成。我可以通过 curl 进行 POST，因此容器上没有网络问题。有什么方法可以调试正在传递的标头、正在命中的 url 等？我不知道缺少什么。

我没有使用 Vault cli。它全部基于 HTTP。

添加-vvvv后是日志：

我尝试在同一个 pod 中运行包含上述所有详细信息的 curl，结果很好。

Answer 1

将-vvvv 添加到您的命令行以进行调试。

正如您指定的body_format: json，您可以简化您的body 部分：

- name: Generate vault token
  uri:
    url: "{{vault_address}}/v1/auth/github/login"
    method: POST
    body:
      token: mytoken
    validate_certs: no
    body_format: json

我能够通过 ansible 版本 2.7.9 解决这个问题我在 2.0.0.2 上
