  - 3) 函数定义
  - - GET
    - POST

使用步骤

1) 导包

from odoo import http或from odoo.http import request

2)类创建

class Yp32011(http.Controller):
	....

3) 函数定义

GET

返回字符串

@http.route('/index', auth='public', methods=["GET"],csrf=False, cors='*')
def index(self):
    return "Hello, world"

返回json

不带参数

@http.route('/projects', auth='public', methods=["GET"],csrf=False, cors='*')
def projects(self):
    project_obj = http.request.env["yp32011.inspection_project"].sudo().search([])
    result = [{
                "id": record.id,
                "name": record.name,
            }
            for record in project_obj]
    return json.dumps(result)

用SQL写法等同于

@http.route('/projects', auth='public', methods=["GET"],csrf=False, cors='*')
def projects_SQL(self):
    http.request.env.cr.execute("select * from yp32011_inspection_project")
    result = http.request.env.cr.fetchall()
    result = [{
                "id": record[0],
                "name": record[1],
            }
            for record in result]
	return json.dumps(result)

带参数
1）通过设置关键字参数获取

@http.route('/projects/<int:project_id>', auth='public', methods=["GET"],csrf=False, cors='*')
def projects(self,project_id=None):
    project_obj = http.request.env["yp32011.inspection_project"].sudo().search([('id','=',project_id)])
    ...

2）通过设置不定长参数kwargs获取

@http.route('/projects/<int:project_id>', auth='public', methods=["GET"],csrf=False, cors='*')
def projects(self,**kwargs):
	# kwargs是个字典
    project_id=kwargs.get('project_id') # 或 kwargs['project_id']
    project_obj = http.request.env["yp32011.inspection_project"].sudo().search([('id','=',project_id)])
     ...

POST

apipost传递的参数

{
	"params": {
		"data": {
			"name": "test2",
			"inspected_procedure":[1],
		}
	}
}

1) 通过http.request.jsonrequest获取参数

@http.route('/project', auth='public', methods=["POST"], type="json",csrf=False, cors='*')
def create_project(self):
    param = http.request.jsonrequest['params']
    # param是个字典
    vals={
        'name':param['data']['name'],
        'inspected_procedure':param['data']['inspected_procedure']
    }
    print(vals)
    http.request.env["yp32011.inspection_project"].sudo().create(vals)
    result={
        "code":200,
        "message":"ok",
        "data":"新建项目成功"
    }
    return json.dumps(result,ensure_ascii=False)

2) 通过设置不定长参数kwargs获取

@http.route('/project', auth='public', methods=["POST"], type="json",csrf=False, cors='*')
def create_project(self,**kwargs):
    vals={
        'name':kwargs['data']['name'], # 或 kwargs.get('data').get('name')
        'inspected_procedure':kwargs['data']['inspected_procedure']
    }
	......

PUT

1）通过设置关键字参数获取获取需修改的记录ID
2）通过http.request.jsonrequest获取需修改的参数内容

@http.route('/projects/<string:pk>', methods=["PUT"], type="json", auth='public', csrf=False, cors='*')
def update_project(self, pk=None):
    param = http.request.jsonrequest
    project_obj = http.request.env["yp32011.inspection_project"].sudo().search([("id", "=", pk)])
    if not project_obj:
        return json.dumps("not exists")
    project_obj.name = param['params']['data']["name"]
    result = [{
        "id": record.id,
        "name": record.name,
    }
        for record in project_obj]
    return json.dumps(result)

DELETE

通过设置关键字参数获取获取需删除的记录ID

@http.route('/projects/<string:pk>', methods=["DELETE"],auth='public', csrf=False, cors='*')
def delete_project(self, pk=None):
    project_obj = http.request.env["yp32011.inspection_project"].sudo().search([("id", "=", pk)])
    if not project_obj:
        return json.dumps("not exists")
    project_obj.unlink()
    result={
        "code":200,
        "message":"ok",
        "data":"删除项目成功"
    }
    return json.dumps(result,ensure_ascii=False)

用法汇总

查看search(domian)

 result = http.request.env['bim5d.quality_standard'].search( [
     ('project_budget','=',project_id),
     ('state','=','done')
 ])

查找总数：search_count(domian)

result = http.request.env["bim5d.quality_record"].sudo().search_count([])

使用SQL:cr.execute(“sql语句”，param)

 http.request.env.cr.execute("select count(*) from (select DISTINCT header,feedback from bim5d_problem_record) t")
 result = http.request.env.cr.fetchone()

返回xml模版页面

return request.render("模块名.template_id", values)

返回json数据集
```
return json.dumps(values)
```

注：domain是一种表达式，通常用来筛选数据记录。

常用函数方法

create(dics):在数据表中插入一条记录，返回新对象。
search(domain):查询符合条件的对象列表，返回对象列表。
search(domain, limit=1):查询符合条件的一个对象，返回一个对象。
search_read(domain, fields):查询符合条件的字典列表。返回指定fields的字典列表。
browse(id):浏览对象及其关联对象。返回对象。
browse([ids]):浏览对象列表，返回对象列表
browse(id).read(fields):浏览对象及其关联对象，返回字典
search(domain).read(fields):返回记录集的指定字段值列表。返回字典列表
write(dics):保存一个或几个记录的一个或几个字段。返回布尔值，True
unlink:删除一个或几个记录
default_get:复位一个或多个字段的缺省值
default_set:重置字段的缺省值
