使用Django将请求发送到外部Rest服务-使用返回的json更新模型

Question

我需要一些关于使用Camunda Rest API和Django实现以下细节的最佳方法的建议：

{"variables":
    {"UserID" : {"value" : "user.", "type": "String"},
     "OrganisationID" : {"value" : "some value", "type": "String"}
    },
     "businessKey" : "SomeBusinessKey"
    }

 import requests

 class StartProcessView(TemplateView):

    template_name = 'startdeliveryphase.html'

    def get(self, request):
        form = StartProject()
        return render(request, self.template_name, {'form':form})





    def post(self,request):
        form = StartProject()
        url = "http://localhost:8080/engine-rest/process-definition/key/Process_B_PerProject/start"
        payload = "{\"variables\":\r\n    {\"Username\" : {\"value\" : \"[form.Username]\", \"type\": \"String\"},\r\n     \"OrganisationInitiating\" : {\"value\" : \"[form.OrganisationInitiator]\", \"type\": \"String\"}},\r\n     \"businessKey\" : {form.businessKey}\r\n    }"
        headers = {
        'Content-Type': 'application/json'
        }
        response = requests.request("POST", url, headers=headers, data = payload)
        return render(response, self.template_name, {'form':form})

 {
    "links": [
        {
            "method": "GET",
            "href": "http://localhost:8080/engine-rest/process-instance/fbff8359-84cd-11ea-a2e1-00155d891509",
                "rel": "self"
            }
        ],
        "id": "fbff8359-84cd-11ea-a2e1-00155d891509",
        "definitionId": "Process_B_PerProject:1:71921815-737c-11ea-91a6-00155d891509",
        "businessKey": "SomeBusinessKey",
        "caseInstanceId": null,
        "ended": false,
        "suspended": false,
        "tenantId": null
}
