Odoo - JsonRPC

1. Odoo内方法结构（接收端）

# -*- coding: utf-8 -*-
import odoo
import logging
import traceback


from odoo import api, fields, models, tools, SUPERUSER_ID, _
from odoo.exceptions import MissingError, UserError, ValidationError, AccessError


class YourModelName(models.Model):
    _name = 'your.model.name'

    @api.model
    def test_jsonrpc(self, args):
        try:
            # TODO SOMETHINGS
            return_json = {
                'code': "SUCCESS",
                'state': 'success',
                'error_msg': '',
                'datas': [
                    {
                        "code": "A01",
                        "name": "名称01",
                        # ...
                    },
                    {
                        "code": "A02",
                        "name": "名称02",
                        # ...
                    }
                    # ...
                ]
            }
        except Exception as e:
            return_json = {
                'code': "ERROR_001",
                'state': 'error',
                'error_msg': 'Error: %s.' % str(traceback.format_exc()),
                'datas': []
            }
        return return_json

2. POST接口请求结构（发送端）

# -*- coding:utf-8 -*-
import json
import uuid
import pprint
import urllib.request

HOST = "xxx.xxx.xxx.xxx"
PORT = 8069
URL = "http://%s:%s/jsonrpc" % (HOST, PORT)
DB_NAME = "odoo12"
USERID = 2
USERNAME = "admin"
PASSWORD = "admin"
ModelName = "your.model.name"
FunctionName = "test_jsonrpc"

UUID = str(uuid.uuid4())
data = {
    "id": UUID,       # 随机码
    "jsonrpc": "2.0",       # 固定值
    "method": "call",       # 固定值
    "params": {
        "service": "object",# 固定值
        "method": "execute",# 固定值
        "args": [
            DB_NAME,        # 数据库名称
            USERID,         # 接口用户ID
            PASSWORD,       # 接口用户密码
            ModelName,      # 模型
            FunctionName,   # 方法
            []              # 参数结构体
        ]
    }
}
req = urllib.request.Request(url=URL, data=json.dumps(data).encode(), headers={"Content-type": "application/json"})
reply = json.loads(urllib.request.urlopen(req).read().decode('UTF-8'))
pprint.pprint(reply)

3. 实例测试

1. Odoo内维护一个jsonrpc的方法：test_jsonrpc

   # -*- coding: utf-8 -*-
   import odoo
   import logging
   import traceback
   
   
   from odoo import api, fields, models, tools, SUPERUSER_ID, _
   from odoo.exceptions import MissingError, UserError, ValidationError, AccessError
   
   
   class IrActions(models.Model):
       _name = 'ir.actions.actions'
       _description = 'Actions'
       _table = 'ir_actions'
       _order = 'name'
   
       @api.model
       def test_jsonrpc(self, args):
           try:
               # TODO SOMETHINGS
               return_json = {
                   'code': "SUCCESS",
                   'state': 'success',
                   'error_msg': '',
                   'datas': [
                       {
                           "code": "A01",
                           "name": "名称01",
                           # ...
                       },
                       {
                           "code": "A02",
                           "name": "名称02",
                           # ...
                       }
                       # ...
                   ]
               }
           except Exception as e:
               return_json = {
                   'code': "ERROR",
                   'state': 'error',
                   'error_msg': 'Error: %s.' % str(traceback.format_exc()),
                   'datas': []
               }
           return return_json
   

2. 在其他系统中进行调用测试

   # -*- coding:utf-8 -*-
   import json
   import uuid
   import pprint
   import urllib.request
   
   HOST = "localhost"
   PORT = 8069
   URL = "http://%s:%s/jsonrpc" % (HOST, PORT)
   DB_NAME = "odoo12_db"
   USERID = 2
   USERNAME = "admin"
   PASSWORD = "admin"
   ModelName = "ir.actions.actions"
   FunctionName = "test_jsonrpc"
   UUID = str(uuid.uuid4())
   data = {
       "id": UUID,       # 随机码
       "jsonrpc": "2.0",       # 固定值
       "method": "call",       # 固定值
       "params": {
           "service": "object",# 固定值
           "method": "execute",# 固定值
           "args": [
               DB_NAME,        # 数据库名称
               USERID,         # 接口用户ID
               PASSWORD,       # 接口用户密码
               ModelName,      # 模型
               FunctionName,   # 方法
               []              # 参数结构体
           ]
       }
   }
   
   req = urllib.request.Request(url=URL, data=json.dumps(data).encode(), headers={"Content-type": "application/json"})
   reply = json.loads(urllib.request.urlopen(req).read().decode('UTF-8'))
   pprint.pprint(reply)
   
   

3. 结果示例
   3.1 若程序正常执行无错误，则返回信息结构如下：
   
   
   
   3.2 如果try语句中执行异常，返回错误信息结构如下：
   
   
   3.3 如果身份验证或者请求参数有误，返回错误信息结构如下：
   
   
   
   3.4 注意如果host和port不对的话，抛出的是Request的请求异常：
