如何使用图谱API更新Azure Ad B2c自定义用户属性

问题描述

我是Azure B2C的新手。我针对用户对象创建了自定义属性extension_role。我想使用图形API更新此属性。我尝试了以下代码

public async Task UpdateUsersRole(string id)
        {
         IDictionary<string,object> extensionInstance = new Dictionary<string,object>();
            extensionInstance.Add("extension_role","admin");
            var user = new User
            {
          
                AdditionalData = extensionInstance

            };

            await  GraphClient.Users[id]
                .Request()
                .UpdateAsync(user);
        }

是更新自定义属性的正确方法吗？执行时我也遇到了错误

代码：Request_BadRequestMessage：指定了一个或多个属性值 无效。内部错误

解决方法

请检查以下代码更改，并验证您尝试更新的用户是否具有自定义属性

public static async Task UpdateCustomAtrributeUserId(GraphServiceClient graphClient)
        {
            Console.Write("Enter user object ID: ");
            string userId = Console.ReadLine();
            string CustomAtrribute = "B2C_Custom_AtrributeName";

 

            Console.WriteLine($"Looking for user with object ID '{userId}'...");

 

            try
            {
              //Get User details to Verify the existing values
                var result = await graphClient.Users[userId]
                  .Request()
                  .Select($"id,givenName,surName,displayName,identities,{CustomAtrribute}")
                  .GetAsync();

 

                Console.WriteLine(result);

 

                if (result != null)
                {
                    //Enter the New custom attribute value
                    Console.WriteLine("Enter custom attribute value");
                    string updatecustomeattribvalue = Console.ReadLine();
                    
                    //Fill custom attribute value
                    IDictionary<string,object> extensionInstance = new Dictionary<string,object>();
                    extensionInstance.Add(CustomAtrribute,updatecustomeattribvalue);
                    //Updating the custom attribute 
                   var updatedresult  = await graphClient.Users[userId]
                            .Request()
                            .UpdateAsync(new User {
                                AdditionalData = extensionInstance
                            });
                   
                    Console.WriteLine(JsonConvert.SerializeObject(updatedresult));
                }
            }
            catch (Exception ex)
            {
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine(ex.Message);
                Console.ResetColor();
            }
        }
