Bob*_* B. 4 asp.net-core x-xsrf-token angular
尝试使用 Angular 和 .NET CORE 实现 XSRF 时,我不断收到此消息:“提供的防伪令牌验证失败。cookie 令牌和请求令牌已交换。” 我在 Angular 和 API 中配置了相同的 cookie 和标头名称。谁有想法?
过程
Angular 首次调用此 API 方法以检索 cookie
[HttpGet("startSession")]
public async Task<IActionResult> StartSession()
{
AntiforgeryTokenSet tokens = this.antiForgery.GetAndStoreTokens(this.HttpContext);
this.HttpContext.Response.Cookies.Append(this.options.Value.Cookie.Name, tokens.RequestToken, new CookieOptions { HttpOnly = false });
return this.Ok(
new
{
Success = true
});
}

然后 Angular 拦截下一个 POST 请求并稍微覆盖默认的 XSRF 处理,因为我需要它为 HTTPS URL 工作
// Override default Angular XSRF handling since it won't work for
absolute URLs and we have to prefix with "https://"
// Source:https://github.com/angular/angular/blob/master/packages/common/http/src/xsrf.ts
@Injectable()
export class HchbHttpXsrfInterceptor implements HttpInterceptor {
constructor(
private tokenService: HttpXsrfTokenExtractor) {}
intercept(req: HttpRequest<any>, next: HttpHandler):
Observable<HttpEvent<any>> {
const headerName = 'X-XSRF-TOKEN';
const lcUrl = req.url.toLowerCase();
// Skip both non-mutating requests.
// Non-mutating requests don't require a token
// anyway as the cookie set
// on our origin is not the same as the token expected by another origin.
if (req.method === 'GET' || req.method === 'HEAD' ) {
return next.handle(req);
}
const token = this.tokenService.getToken();
// Be careful not to overwrite an existing header of the same name.
if (token !== null && !req.headers.has(headerName)) {
req = req.clone({headers: req.headers.set(headerName, token)});
}
return next.handle(req);
}
}

我遇到了同样的问题,我想我发现了问题。该options.Cookie.Name中AddAntiforgery 必须是不同的比你手动设置使用cookie context.Response.Cookies.Append。
尝试更改其中之一的名称,它会起作用。现在,您将使用options.Cookie.Name名称和tokens.RequestToken值覆盖生成的 cookie 。
您可以注意到开发人员工具中的差异。
options.Cookie.Name标记为http only( HttpOnly = true)context.Response.Cookies.Append标记为HttpOnly = false第二个是从 JS/Angular 读取的(您可以在 JS 中读取它,因为HttpOnly=false和 作为 ajax 请求中的标头发送并针对无法从 JS 读取的默认值进行验证)
