.net core webapi设置response的headers
时间: 2023-03-02 19:46:34 浏览: 135
要设置.NET Core WebAPI响应的头部(headers),可以在WebAPI控制器中使用Response.Headers属性。
以下是一个示例:
```csharp
[ApiController]
[Route("[controller]")]
public class MyController : ControllerBase
{
[HttpGet]
public ActionResult<string> Get()
{
Response.Headers.Add("Custom-Header", "Hello World");
return "Response with custom header";
}
}
```
在上面的示例中,我们使用Response.Headers.Add方法向响应添加一个自定义标头"Custom-Header",值为"Hello World"。

.net core web api请求头怎么配置
在 .NET Core Web API 中,可以通过以下方式来配置请求头:
1. 在 Startup.cs 文件的 ConfigureServices 方法中,添加以下代码来配置 CORS(跨域资源共享)策略:
```
services.AddCors(options =>
{
options.AddPolicy("AllowAllOrigins",
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader();
});
});
```
2. 在 Startup.cs 文件的 Configure 方法中,使用以下代码来启用 CORS:
```
app.UseCors("AllowAllOrigins");
```
3. 在 API 控制器中,可以通过以下方式来设置特定的请求头:
```
[HttpGet]
public IActionResult Get()
{
Response.Headers.Add("Custom-Header", "Custom Value");
return Ok();
}
```
这些代码将允许任意来源、任意方法和任意请求头。你可以根据自己的需求进行适当的修改。
js-cookie设置token过期时间_详解ASP.NET Core Web Api之JWT刷新Token_实用技巧
好的,我了解您的问题。关于js-cookie设置token过期时间,我们可以通过设置cookie的expires属性来实现。示例代码如下:
```
// 设置cookie过期时间为1小时
Cookies.set('token', 'your_token', { expires: 1/24 });
// 获取cookie过期时间
var expires = new Date(Cookies.get('token')).toUTCString();
console.log('token过期时间:' + expires);
```
另外,关于ASP.NET Core Web Api之JWT刷新Token,我们可以通过设置Token过期时间,并在Token过期前刷新Token来实现。示例代码如下:
```
// 在Startup.cs中设置Token认证
services.AddAuthentication(options =>
{
options.DefaultAuthenticateScheme = JwtBearerDefaults.AuthenticationScheme;
options.DefaultChallengeScheme = JwtBearerDefaults.AuthenticationScheme;
}).AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuer = true,
ValidateAudience = true,
ValidateLifetime = true,
ValidateIssuerSigningKey = true,
ValidIssuer = Configuration["Jwt:Issuer"],
ValidAudience = Configuration["Jwt:Issuer"],
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"]))
};
options.Events = new JwtBearerEvents
{
OnAuthenticationFailed = context =>
{
if (context.Exception.GetType() == typeof(SecurityTokenExpiredException))
{
context.Response.Headers.Add("Token-Expired", "true");
}
return Task.CompletedTask;
}
};
});
// 在Token过期前刷新Token
[HttpPost("refresh-token")]
public async Task<IActionResult> RefreshToken([FromBody] TokenRequestModel model)
{
var principal = GetPrincipalFromExpiredToken(model.Token);
var username = principal.Identity.Name; //retrieve the username of the person we are refreshing
var user = await _userManager.FindByNameAsync(username);
if (user == null || user.RefreshToken != model.RefreshToken || user.RefreshTokenExpiryTime <= DateTime.UtcNow)
{
return BadRequest("Invalid client request");
}
var newJwtToken = GenerateJwtToken(user);
var newRefreshToken = GenerateRefreshToken();
user.RefreshToken = newRefreshToken;
await _userManager.UpdateAsync(user);
return new ObjectResult(new TokenResponseModel
{
Token = newJwtToken,
RefreshToken = newRefreshToken
});
}
// 获取Token中的Principal
private ClaimsPrincipal GetPrincipalFromExpiredToken(string token)
{
var tokenValidationParameters = new TokenValidationParameters
{
ValidateAudience = false,
ValidateIssuer = false,
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"])),
ValidateLifetime = false //here we are saying that we don't care about the token's expiration date
};
var tokenHandler = new JwtSecurityTokenHandler();
var principal = tokenHandler.ValidateToken(token, tokenValidationParameters, out var securityToken);
var jwtSecurityToken = securityToken as JwtSecurityToken;
if (jwtSecurityToken == null || !jwtSecurityToken.Header.Alg.Equals(SecurityAlgorithms.HmacSha256, StringComparison.InvariantCultureIgnoreCase))
throw new SecurityTokenException("Invalid token");
return principal;
}
// 生成新的JWT Token
private string GenerateJwtToken(User user)
{
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.UserName),
new Claim("userId", user.Id.ToString())
};
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"]));
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
var expires = DateTime.UtcNow.AddMinutes(Convert.ToDouble(Configuration["Jwt:ExpireMinutes"]));
var token = new JwtSecurityToken(
Configuration["Jwt:Issuer"],
Configuration["Jwt:Issuer"],
claims,
expires: expires,
signingCredentials: creds
);
return new JwtSecurityTokenHandler().WriteToken(token);
}
// 生成新的Refresh Token
private string GenerateRefreshToken()
{
var randomNumber = new byte[32];
using (var rng = RandomNumberGenerator.Create())
{
rng.GetBytes(randomNumber);
return Convert.ToBase64String(randomNumber);
}
}
```
希望这些代码对您有所帮助!
