建設網(wǎng)站的方案抖音競價推廣怎么做
??重新創(chuàng)建WebApi項目，安裝Microsoft.AspNetCore.Authentication.JwtBearer包，將之前JwtBearer測試項目中的初始化函數(shù)，jwt配置類、token生成類全部挪到項目中。
??重新編寫login函數(shù)，之前測試Cookie和Session認證時用的函數(shù)適合mvc模式，WebApi項目下函數(shù)返回的是狀態(tài)碼及其它信息，直接將開源博客Blog項目中的ApiResult類照搬過來，如果登錄成功則將token保存到Msg屬性中返回客戶端。login函數(shù)的主要代碼如下（用戶名及密碼驗證還是寫死的，后續(xù)再調整成從數(shù)據(jù)庫中查詢）：
public async Task<ApiResult> Login([FromBody]UserInfo info)
{if (info.Name == "gc_2299" && info.Password == "XXXXXX"){ApiResult result = new ApiResult();result.UserName = info.Name;result.Msg=GetToken(info.Name);return result;}else{return new ApiResult("身份驗證失敗", 500, false);}
}private string GetToken(string name)
{List<Claim> claims = new List<Claim>();claims.Add(new Claim(ClaimTypes.Name, name)); DateTime expres = DateTime.Now.AddSeconds(_jwtconfig.Value.Expres);byte[] secbyse = Encoding.UTF8.GetBytes(_jwtconfig.Value.Key);var secKey = new SymmetricSecurityKey(secbyse);var credetials = new SigningCredentials(secKey, SecurityAlgorithms.HmacSha256);var tokenDescriptor = new JwtSecurityToken(claims: claims, expires: expres, signingCredentials: credetials, issuer:_jwtconfig.Value.Issuer, audience: _jwtconfig.Value.Audience);return new JwtSecurityTokenHandler().WriteToken(tokenDescriptor);
}
??前端登錄頁面也是直接復制的開源博客Blog項目中的后臺登錄頁面，簡化了不少東西。不過沒法直接用它的js代碼（使用jQuery的post方法調不到后臺的login函數(shù)，暫時不清楚怎么回事兒，網(wǎng)上很多示例都是用的ajax，所以改成了ajax），將登錄函數(shù)的js代碼修改如下：
layui.use(['layer', 'form'], function () {var layer = layui.layer;var form = layui.form,$ = layui.jquery;form.on("submit(login)",function (data) {login();});function login() {var $btn = $("#btnLogin");$btn.text("登錄中...").attr("disabled", "disabled").addClass("layui-disabled");var parm = {};$("form input").each(function () {parm[$(this).attr("name")] = $(this).val();}); $.ajax({type: 'POST',url: 'https://localhost:7051/Login/Login',contentType: 'application/json',data: JSON.stringify(parm),success: function (result) {if (result.statusCode == 200) {layer.msg("登錄成功,歡迎" + result.userName +"，你的token=" + result.msg);sessionStorage.setItem("user", result.userName)sessionStorage.setItem("token", result.msg);}else{layer.msg("登錄失敗，錯誤消息為：" + result.msg);}$btn.text('登錄').removeClass("layui-disabled").removeAttr("disabled");},error: function () {layer.msg("登錄失敗");$btn.text('登錄').removeClass("layui-disabled").removeAttr("disabled");}});}
});
??最后是登錄效果，截圖如下：
??從瀏覽器的會話存儲空間中可以看到登錄成功后保存的用戶名及token，便于其它頁面使用。
