c# - 如何在 Blazor 应用程序中从 Http.PutAsJsonAsync 传递多个字符串值

问题描述

我需要发布两个字符串值以在数据库中添加公司。在这里，我将 PUT 写为

 await Http.PutAsJsonAsync($"api/B2CUsers/company/invitation/add/{UtpID}/{User.email}",UtpID,User.email);

我收到一个错误 User.email，上面写着cannot convert string to System.Text.Json.JsonSerializerOptions.

控制器功能：

[HttpPut("company/invitation/add/{utpid}/{emailAddressInvitedUser}")]
        public async Task<int> AddUserCompanyInvitationAsync(string utpid, string emailAddressInvitedUser)
        {
            string userid = GetCurrentUser();
            return await _iB2CUserServiceRepository.AddUserCompanyInvitation(userid, utpid, emailAddressInvitedUser);
        }

解决方案

正确的函数签名是

[HttpGet("company/invitation/add2/{utpid}/{emailAddressInvitedUser}")]
public Task<int> AddUserCompanyInvitationAsync([FromRoute] string utpid, [FromRoute] string emailAddressInvitedUser)

如果您不添加 [FromRoute] 属性，.NET 不会将路由值映射到您的变量。

请记住，此类请求将记录在 Web 服务器日志中。这意味着电子邮件地址将在日志中可见。您还需要使用HttpUtility.UrlEncode转义电子邮件字符串

curl -X PUT "http://localhost:14786/company/invitation/add2/45/test%40test.com" -H "accept: text/plain"

首选的方法是在正文中传递 Json 请求。

public class AddUserRequest
{
    public int utpid { get; set; }
    public string emailAddressInvitedUser { get; set; }
}

public class AddUserResponse
{
    public int uid { get; set; }
}
[HttpPut("company/invitation/add1")]
public Task<AddUserResponse> AddUserCompanyInvitationAsync([FromBody]AddUserRequest addUserRequest)
{
    Console.WriteLine(addUserRequest.utpid);
    Console.WriteLine(addUserRequest.emailAddressInvitedUser);
    return Task.FromResult(new AddUserResponse() { uid = 1 });
}

并为客户

var client = new HttpClient();
int id = 45;
string email = "test@test.com";
await client.GetAsync($"http://localhost:14786/company/invitation/add2/{id}/{System.Web.HttpUtility.UrlEncode(email)}");

var response = await client.PutAsJsonAsync("http://localhost:14786/company/invitation/add1", new AddUserRequest() { utpid = id, emailAddressInvitedUser = email });

而不是 PUT 使用 POST
