使用 Python 请求 post() 方法向 Dynamics 365 发送数据以创建事件

问题描述

我尝试编写代码来发送数据以使用 Python 请求 post() 方法创建 Dynamics 365 事件，但我遇到了问题。 我使用python 3.6， 我使用此代码，但它给了我这个错误

{'error': {'code': '','message': "The requested resource does not support http method 'POST'."}}

代码：

import requests  
import json

#set these values to retrieve the oauth token
crmorg = 'https://xxxxxx.crm4.dynamics.com/' #base url for crm org  
clientid = 'xxxxxxxxxxx' #application client id  
tokenendpoint = 'https://login.microsoftonline.com/xxxxxxxxxx/oauth2/token' #oauth token endpoint
secret = 'xxxxxxxxxxxxxxxxx'
#set these values to query your crm data
crmwebapi = 'https://xxxxxx.api.crm4.dynamics.com/api/data/v9.1/Incident' #full path to web api endpoint  
#crmwebapiquery = 'contacts?$select=fullname,contactid' #web api query (include leading /)

#build the authorization token request
tokenpost = {  
    'client_id':clientid,'resource':crmorg,'client_secret' : secret,'grant_type':'client_credentials',}

#make the token request
tokenres = requests.post(tokenendpoint,data=tokenpost)

#set accesstoken variable to empty string
accesstoken = ''

#extract the access token
try:  
    accesstoken = tokenres.json()['access_token']
except(KeyError):  
    #handle any missing key errors
    print('Could not get access token')

#if we have an accesstoken
if(accesstoken!=''):  
    #prepare the crm request headers
    crmrequestheaders = {
        'Authorization': 'Bearer ' + accesstoken,'OData-MaxVersion': '4.0','OData-Version': '4.0','Accept': 'application/json','Content-Type': 'application/json; charset=utf-8','Prefer': 'odata.maxpagesize=500','Prefer': 'odata.include-annotations=OData.Community.display.V1.FormattedValue'
    }
    incidentdata={
    "title": "test","customerid_account": "xxxxxxxxxxxxxxx","forte_casetypeid": "xxxxxxxxxxxxx","forte_casecategoryid": "xxxxxxxxxxxxxxxxxxx","primarycontactid": "xxxxxxxxxxxxxxxxx","entitlementid": "xxxxxxxxxxxxxxxxxxxxx",}

  
    #make the crm request
    crmres = requests.post(crmwebapi,headers=crmrequestheaders,data=json.dumps(incidentdata))
    try:
        #get the response json
        crmresults = crmres.json()
        print(crmresults)


    except KeyError:
        #handle any missing key errors
        print('Could not parse CRM results')

解决方法

让我建议一些修复和测试代码的事情。

1. 应更正实体名称

以下两个端点都应该有效，但 incidents 是正确的实体名称。

crmwebapi = 'https://xxxxxx.api.crm4.dynamics.com/api/data/v9.1/incidents'
crmwebapi = 'https://xxxxxx.crm4.dynamics.com/api/data/v9.1/incidents' 

2. 删除 Prefer 标头，因为它们仅用于 GET 请求

试试下面的标题。

crmrequestheaders = {
        'Authorization': 'Bearer ' + accesstoken,'OData-MaxVersion': '4.0','OData-Version': '4.0','Accept': 'application/json','Content-Type': 'application/json; charset=utf-8',}

3. 分配查找/导航属性时 - 使用 @odata.bind

检查以下内容并进行相应调整。

incidentdata={
"title": "test","[e-mail]": "/accounts(xxxxxxxxxxxxxxx)","forte_casetypeid": "xxxxxxxxxxxxx","forte_casecategoryid": "xxxxxxxxxxxxxxxxxxx","[e-mail]": "/contacts(xxxxxxxxxxxxxxxxx)","[e-mail]": "/entitlements(xxxxxxxxxxxxxxxxxxxxx)",}
