片言

此文中代码都是笔者工作中源码，所以不会很完整，主要摘常见场景的api片段用以举例说明

另:此文主要针对自动化测试人员，尤其有python基础阅读更佳。

笔者使用 python3.6 + postgresql10 + flask 0.12 的环境

场景介绍 

我们要实现后台管理中的用户管理功能，实现对用户的增、修改、删除、查询操作。

文中场景省去登录和用户权限部分，但我会在接口代码片段中进行注释说明

接口：新增用户

（定义访问的http链接地址，以及请求使用的 method）    http://127.0.0.1:7070/guardian/users

 
@app.route('/guardian/users', methods=['POST'])    # 使用 POST 方法
@require_role('guardian_admin')    # 登录用户的角色权限必须是guardian_admin 此处是自定义的更角色管理中的设置管理员角色一致即可。不需要角色权限也可以注释此行即可
@login_required    # 验证用户登录 flask_login插件
def create_user():
    '''
    下面json串是新增时候前台表单提交的内容以及格式，也就是我们接口测试时候需要添加的测试数据
    {
            "user": {
                "domain_id": "default",
                "enabled": True,
                "name": "tsbc1",
                "password": "111111",
                "realname": "Ray",
                "email": "tsbc@vip.qq.com",

测试脚本（新增用户）

python unittest做单元测试

 
import unittest, requests
 
class GuardianTestCase(unittest.TestCase):
    guardian_base = 'http://127.0.0.1:7070'
    user_token = keystone.user_token('default', 'tsbc', '123456') # 调用keystone生成登录用户的token
    
def test_create_user_api(self):
        # 添加对应headers 及 tonken 用于数据传参和登录认证使用
        myheaders = {'Content-Type': 'application/json'}

接口：修改用户

修改用户和新增用户传递的参数差不多，使用的是http的patch请求，route要添加user_id的参数 ，其他实现和新增差不多代码不重复贴了

 
@app.route('/guardian/users/<string:user_id>', methods=['PATCH'])
@require_role('guardian_admin')
@login_required
def update_user(user_id):
    """
    此处省略接收请求数据代码
    """
    try:
            resp = usermgt.update_user(domain_id, user_id, username, user_passwd, project_id, enabled) # 更新keystone 用户密码、状态
            if resp is not None:
                # 更新用户基本信息与新增是同一个接口，执行SQL时使用PostGresql特性，相同user_id数据只更新不会再插入
                GuardianModelDao._save_update_users_info(user_id, username, real_name, email, tel, phone, org_id, org_array, comments)
                return wrap_response(SUCCESS_MSG, 200)    # 更新成功返回 200
        except Exception as e:
            LOG.exception('error modify user', e)
            abort(500)    # 更新失败500

            LOG.error('error update users, response: {0}, status: {1}'.format(resp_json, _resp.status_code))
接口：查询用户

根据用户名查询用户，使用http的get请求

 
@app.route('/guardian/users/<string:user_name>', methods=['GET'])    # 查询使用 GET 方法
@require_role('guardian_admin')
@login_required
def query_user_by_username(user_name):
 
    try:
        user_info = GuardianModelDao._query_users_info_by_name(user_name)    # 调用后台查询函数
        if len(user_info):
            return wrap_response(jsonpickle.dumps(user_info), 200)    # 成功返回200 并把返回内容转换成 json格式
        else:
            return wrap_response("[]", 200)   # 否则返回空
    except Exception as e:
        LOG.exception('error query user by name', e)
        abort(500)
后台函数
 
@classmethod
    def _query_users_info_by_id(cls, user_id):
        LOG.debug('start list users info...')
        users = []
        with TxConn() as conn:
            try:
                with conn.cursor() as cursor:

                    for (user_id, real_name, email, tel, phone, org_id, org_array, comments, create_time, update_time) in cursor:
                        user = Users(user_id, real_name, email, tel, phone, org_id, org_array, comments, create_time, update_time)
                        users.append(user)
            except Exception as e:
                LOG.exception('error query users !')
                raise e

        else:
            LOG.error('error query users, response: {0}, status: {1}'.format(resp_json, _resp.status_code))
接口：删除用户

根据用户ID进行删除，使用http的delete请求

 
@app.route('/guardian/users/<string:user_id>', methods=['DELETE']) # 传入用户id 使用 delete请求
@require_role('guardian_admin')
@login_required
def delete_user(user_id):
    if user_id is None:
        abort(400)
    try:
        s_code = usermgt.delete_user(user_id)
        if s_code == 204:
            return wrap_response(SUCCESS_MSG, status=s_code) # 返回状态码
    except Exception as e:
        LOG.exception('error delete users info', e)
        abort(500)

后台函数

 
def delete_user(user_id):
    myheaders = {'Content-Type': 'application/json'}
    myheaders['X-Auth-Token'] = settings.KEYSTONE_ADMIN_TOKEN
    _resp = requests.delete(settings.KEYSTONE_BASE + '/v3/users/'+user_id,
                            headers=myheaders, verify=False)
 
    if _resp.status_code == 204:
        LOG.debug('delete users -- response {0}'.format(_resp))
        return _resp.status_code
    else:
        LOG.error('error list users, response: {0}'.format(_resp))
        raise KeystoneException('error delete user {0} with response status {1}'
                                .format(user_id, _resp.status_code), _resp.status_code)

测试脚本(删除用户)

 
def test_delete_users_api(self):
 
        myheaders = {'Content-Type': 'application/json'}
        myheaders['X-Subject-Token'] = self.user_token
        _resp = requests.delete(self.guardian_base + '/guardian/users/tsbc1', headers=myheaders, # 使用 delete 请求
                                verify=True)
        resp_json = _resp.content
        # 根据返回状态进行校验

        else:
            LOG.error('error delete users api, response: {0}, status: {1}'.format(resp_json, _resp.status_code))
下面提供给前端API文档
## CREATE USER

1. URL:’ /guardian/users’

2. METHOD: POST

3. body:

 
{
            "user": {
                "domain_id": "default",
                "enabled": True,
                "name": "tsbc1",
                "password": "111111",
                "realname": "Ray",
                "email": "haoydun@123.com",
                "tel":"+86-029-88880000",
                "phone": "13800138000",
                "org_id": "7d22d25a-b648-4ad3-a834-2398eb989a9e",
                "org_array": null,
                "comments": "备注信息"
            }
}
##  UPDATE USER

1. URL:’ /guardian/users/<string:user_id>’

2. METHOD: PATCH2. body:

 
{
            "user": {
                "domain_id": "default",
                "enabled": True,
                "name": "tsbc1",
                "password": "111111",
                "realname": "Ray",
                "email": "tsbc@vip.qq.com",
                "tel":"+86-029-88880000",
                "phone": "13800138000",
                "org_id": "7d22d25a-b648-4ad3-a834-2398eb989a9e",
                "org_array": null,
                "comments": "备注信息"
            }
  }

该接口可以用于修改密码，禁用用户

## QUERY USER BY NAME

1. URL:’ /guardian/users/<string:user_name>’

2. METHOD: GET

## DELETE USER

1. URL: ‘/guardian/users/<string:user_id>’

2. METHOD: DELETE

最后感谢每一个认真阅读我文章的人，礼尚往来总是要有的，虽然不是什么很值钱的东西，如果你用得到的话可以直接拿走：

这些资料，对于【软件测试】的朋友来说应该是最全面最完整的备战仓库，这个仓库也陪伴上万个测试工程师们走过最艰难的路程，希望也能帮助到你！
