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

Question

我尝试编写代码以使用 Python 请求 post() 方法发送数据以创建事件到 Dynamics 365，但我遇到了问题。我使用 python 3.6，我使用这段代码，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')

让我提出一些建议来修复和测试代码。

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'

删除 Prefer headers，因为只有 GET 个请求需要它们

试试下面的 headers。

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

分配 lookup/navigation 属性时 - 使用 @odata.bind

检查下方并相应调整。

incidentdata={
"title": "test",
"customerid_account@odata.bind": "/accounts(xxxxxxxxxxxxxxx)",
"forte_casetypeid": "xxxxxxxxxxxxx",
"forte_casecategoryid": "xxxxxxxxxxxxxxxxxxx",
"primarycontactid@odata.bind": "/contacts(xxxxxxxxxxxxxxxxx)",
"entitlementid@odata.bind": "/entitlements(xxxxxxxxxxxxxxxxxxxxx)",
}

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

send data to create incident to Dynamics 365 with Python Requests post() Method

dynamics-crm

python-3.x

dynamics-crm-webapi
