如何使用 python 更新 Azure 服务端点？

Question

目前我有一个 python 函数，它获取 Azure DevOps 服务连接的信息。问题是我想更新它，并且使用 PUT 请求我总是遇到身体问题。我尝试使用 Postman 来测试它是否有效，并且确实有效。问题仅存在于 python 代码上。 我的代码是这样的：

def update_sc_key(secret_value, app_name, sc_dependence):

print(f"SC DEPENDENCE:",sc_dependence)
personal_access_token = get_pat()
bearer = get_bearer()

if sc_dependence == True:
    
    pat_credentials = BasicAuthentication('', personal_access_token)
    connection = Connection(base_url=organization_url, creds=pat_credentials)  
    
    service_connection_name = app_name[len('SP_') + app_name[len('SP_'):].find('_') - 4:]  
    print(service_connection_name)
        
    service_endpoint_client = connection.clients.get_service_endpoint_client()  
    service_connections = service_endpoint_client.get_service_endpoints(project_name)  
    
    for service_connection in service_connections:
        
        if service_connection.name == "RENEWAL_SC_TEST": # service_connection_name
            
            print(f'SERVICE CONNECTION NAME:', service_connection.name) 
            service_connection_id = service_connection.id  
            print(f'SERVICE CONNECTION ID:', service_connection_id)
            
            # Get Service Connection body
            project_url = organization_url + project_name + "/_apis/serviceendpoint/endpoints"
            
            try:
            # GET RESPONSE
             
                get_params = {  
                    "endpointIds": service_connection_id,  
                    "api-version": "7.1-preview.4"  
                }  
                get_headers={  
                    "Authorization": "Bearer " + bearer  
                } 

                get_response = requests.get(project_url, params=get_params, headers=get_headers)
                get_response_tr = get_response.json()

                get_data_obj1 = get_response_tr['value']
                get_data_obj2 = str(get_data_obj1)
                get_data_obj3 = get_data_obj2[1:-1]

                if get_response.status_code == 200:  

                    get_data_obj_mod = get_data_obj3.replace("'authenticationType': 'spnKey'", "'authenticationType': 'spnKey', 'serviceprincipalkey': '" + secret_value + "'")  
                    get_data_obj_mod_rep = get_data_obj_mod.replace("'", "\"").replace("True", "true").replace("False", "false")  
                    get_data_obj_mod_rep = json.load(get_data_obj_mod)
                    print(get_data_obj_mod_rep)              
                    
                else:  

                    print(f"Error: {get_response.status_code} - {get_response.text}")  
            

                # PUT RESPONSE TO CHANGE PWD
  
                put_params = {
                    "endpointId": service_connection_id,  
                    "api-version": "7.1-preview.4"  
                }
                put_headers={  
                    "Authorization": "Bearer " + bearer,
                    "Content-Type": "application/json"
                } 
                put_body={
                    "body": get_data_obj_mod_rep
                }

                put_response = requests.put(project_url, params=put_params, headers=put_headers, data=put_body)
                
                print(put_response.status_code)
                print(put_response.text)
                
            except json.JSONDecodeError as e:
                print("ERROR: expired bearer token") 
            
else:
    print(f'No Service Connection')  

正如我所说，变量“get_data_obj_mod_rep”的结果在 Postman 上有效，但如果我在 python 上使用相同的结果，则会收到此错误：

{"$id":"1","innerException":null,"message":"值不能为空。 参数名称：endpoint","typeName":"System.ArgumentNullException, mscorlib","typeKey":"ArgumentNullException","errorCode":0,"eventId":0}

根据您的Python示例，我可以重现类似的问题。

为了解决这个问题，我改用另一种python格式来获取服务连接体并修改。

这是一个例子：

import requests
import json

url = "https://dev.azure.com/org/projectname/_apis/serviceendpoint/endpoints/serviceconnectionid?api-version=7.1-preview.4"


headers = {
  'Content-Type': 'application/json',
  'Authorization': 'Basic Based64token',
}

get_response = requests.request("Get", url, headers=headers)
secret_value = "xxxxx"
get_data_obj_mod = json.loads(get_response.content)


get_data_obj_mod["authorization"]["parameters"]["serviceprincipalkey"] = secret_value

ref_format = json.dumps(get_data_obj_mod, indent=2)

response = requests.request("PUT", url, headers=headers, data=ref_format)

print(response.text)

这样我就可以成功更新服务连接了。
