从List 在ASP.NET Web API中获取项目

Question

我正在登录时创建索赔清单：

var claims = new List<Claim>
            {
                new Claim(JwtRegisteredClaimNames.Sub, user.UserName),
                new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()),
                new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
                new Claim("Testing", "test")
            };

没有对Login方法的授权，因此尚未保存声明或未创建cookie，但是列表包含已创建的userId，我想将其保存在活动日志（表）中：

var activityLog = new AccessLogEntity
            {
                ActivityDate = DateTime.UtcNow,
                UserId = ## get from claims (List<Claim>
            };

            await _context.tbl_ActivityLogs.AddAsync(activityLog);
            await _context.SaveChangesAsync();

我该如何实现？

Answer 1

var claims = new List<Claim>
            {
                new Claim(JwtRegisteredClaimNames.Sub, /* -----> */ user.UserName /*<------ this one here */ )   ,
                new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString()),
                new Claim(ClaimTypes.NameIdentifier, user.Id.ToString()),
                new Claim("Testing", /* -----> */"test"/* <----- Or this */)
            };

您可以轻松地做到这一点

claims[0 /* Or whichever you want to get*/].Value;

完整代码

var activityLog = new AccessLogEntity
{
    ActivityDate = DateTime.UtcNow,
    UserId = claims[i /*Or whatever*/].Value;
};

await _context.tbl_ActivityLogs.AddAsync(activityLog);
await _context.SaveChangesAsync();
