根据 services 调用 后端对应服务的 方法method 【定义 openerp\http.py 之 dispatch_rpc()】,然后再将结果从python dict 转换为 xml-rpc 格式 或者 json-rpc 返回
service 对应的后端服务分别是
common, openerp.service.common
db,openerp.service.db
object , openerp.service.model
report, openerp.service.report
各服务提供的方法如下
service
method
说明
common
login
authenticate
version
about
set_loglevel
db
create_database
duplicate_database
drop
dump
restore
rename
change_admin_password
migrate_database
db_exist
list
list_lang
list_countries
server_version
object
execute
execute_kw
execute_workflow
report
report
report_get
render_report
实现自己的方法时,要按照约定,以 ‘exp_‘ 开头。
XML-RPC接口调用
#在 note.note 模型创建新纪录
import xmlrpclib root = ‘%s:%d/xmlrpc/‘ % (HOST, PORT) uid = xmlrpclib.ServerProxy(root + ‘common‘).login(DB, USER, PASS) # common是服务,login 是方法 print "Logged in as %s (uid: %d)" % (USER, uid) # Create a new note sock = xmlrpclib.ServerProxy(root + ‘object‘) args = { ‘color‘ : 8, ‘memo‘ : ‘This is a note‘, ‘create_uid‘: uid, }
note_id = sock.execute(DB, uid, PASS, ‘note.note‘, ‘create‘, args) #调用服务‘object‘的方法 execute(),传入的参数为 (DB, uid, PASS, ‘note.note‘, ‘create‘, args)
JSON-RPC接口调用
#在 note.note 模型创建新纪录
import jsonrpclib
# server proxy object
url = "%s:%s/jsonrpc" % (HOST, PORT)
server = jsonrpclib.Server(url)
# log in the given database
uid = server.call(service="common", method="login", args=[DB, USER, PASS]) #调用服务‘common‘的方法 login()
# helper function for invoking model methods
def invoke(model, method, *args):
args = [DB, uid, PASS, model, method] + list(args)
return server.call(service="object", method="execute", args=args) #调用服务‘object‘的方法 execute()
# create a new note
args = {
‘color‘ : 8,
‘memo‘ : ‘This is another note‘,
‘create_uid‘: uid,
}
note_id = invoke(‘note.note‘, ‘create‘, args) #传入参数
其他
同时odoo Web 还为 odoo web client 提供了 大量的 json-rpc接口。例如数据集提供的服务如下,, 定义在 class DataSet(http.Controller) [ addons\web\controllers\main.py ]。
routing
说明
/web/dataset/search_read
/web/dataset/load
/web/dataset/call
/web/dataset/call_kw
/web/dataset/call_buttion
/web/dataset/exec_workflow
/web/dataset/resequence
webclient 在调用 工作流时,直接 调用 rpc服务
/**
* Executes a signal on the designated workflow, on the bound OpenERP model
*
* @param {Number} id workflow identifier
* @param {String} signal signal to trigger on the workflow
*/
exec_workflow: function (id, signal) {
return session.rpc(‘/web/dataset/exec_workflow‘, {
model: this.name,
id: id,
signal: signal
