[英]How to display images saved in wwwroot (asp.net core ) in Angular project
[英]Can't get Angular with ASP.Net API project running on Kestrel server using wwwroot as path to Angular project files
信息- 我正在 VS Code 中成功運行和調試我的(Angular 10 / ASP.Net 5)站點,使用 >ng serve 和 >dotnet run 連接到 localhost:4200,我現在想將它發布到 Azure,但首先我想要僅在 Kestrel 上進行本地測試,方法是將 Angular 項目構建到 .Net API 項目中的 wwwroot 文件夾並從 localhost:5001 運行該站點。 我在我的 API 項目文件夾中構建(>ng build)到 wwwroot,我看到所有 Angular 文件都在 wwwroot 文件夾中創建,然后我執行 >dotnet run。
我懂了
現在收聽:https://localhost:5001
然后我打開瀏覽器點擊 url 我在終端看到這些錯誤
信息:Microsoft.AspNetCore.Hosting.Diagnostics[1] 請求開始 HTTP/1.1 GET https://localhost:5001/ - - 信息:Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2] 授權失敗。 未滿足這些要求: DenyAnonymousAuthorizationRequirement:需要經過身份驗證的用戶。 信息:Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler[12] AuthenticationScheme:承載被挑戰。 信息:Microsoft.AspNetCore.Authorization.DefaultAuthorizationService[2] 授權失敗。 未滿足這些要求: DenyAnonymousAuthorizationRequirement:需要經過身份驗證的用戶。 信息:Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerHandler[12] AuthenticationScheme:承載被挑戰。 信息:Microsoft.AspNetCore.Hosting.Diagnostics[2] 請求完成 HTTP/1.1 GET https://localhost:5001/ - - - 401 0 - 70.3847ms
問題- 這是配置問題嗎? CORS/權限問題? 身份驗證問題? 文件夾/路徑問題?
這是附加代碼,可幫助任何可能幫助我了解正在發生的事情的人
啟動.cs
配置服務()
public void ConfigureServices(IServiceCollection services)
{
services.AddAutoMapper(typeof(MappingEvents));
services.AddAutoMapper(typeof(MappingMembers));
services.AddAutoMapper(typeof(MappingUsers));
services.AddAutoMapper(typeof(MappingYogabands));
services.AddAutoMapper(typeof(MappingReviews));
// services.AddControllers();
services.AddControllers()
.AddNewtonsoftJson(opt =>
{
opt.SerializerSettings.ReferenceLoopHandling =
Newtonsoft.Json.ReferenceLoopHandling.Ignore;
});
services.AddDbContext<DataContext>(x =>
x.UseSqlServer(_config.GetConnectionString("SqlServerConnection"), y => y.UseNetTopologySuite()));
services.AddTransient<IEmailSender, EmailSender>();
services.Configure<AuthMessageSenderOptions>(_config.GetSection("SendGrid"));
services.Configure<ConfirmationOptions>(_config.GetSection("Confirmation"));
services.Configure<CloudinarySettings>(_config.GetSection("CloudinarySettings"));
services.AddApplicationServices();
services.AddIdentityServices(_config);
services.AddSwaggerDocumentation();
// telling out client app, that if it's running on an unsecure port, we won't return a header,
// that will allow our browser to display that information
// * only allowed to access info from localhost:4200, all others will be denied?
services.AddCors(opt =>
{
opt.AddPolicy("CorsPolicy", policy =>
{
policy.AllowAnyHeader().AllowAnyMethod().WithOrigins("https://localhost:4200");
});
});
}
配置()
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseMiddleware<ExceptionMiddleware>();
// when coming into the server and we don't have an endpoint that matches the request, then we hit this below
// it will then re direct to our error controller, pass in the status code and return an object result
app.UseStatusCodePagesWithReExecute("/errors/{0}"); // after creating ErrorController
app.UseHttpsRedirection();
app.UseRouting();
app.UseCors("CorsPolicy");
app.UseAuthentication();
app.UseAuthorization();
app.UseSwaggerDocumention();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers().RequireAuthorization();
// endpoints.MapControllers();
endpoints.MapFallbackToController("Index", "Fallback");
});
}
AddIdentityService()(在 ConfigureServices() 中調用)
public static IServiceCollection AddIdentityServices(this IServiceCollection services, IConfiguration config)
{
services.Configure<IdentityOptions>(options =>
{
options.User.RequireUniqueEmail = true;
options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@";
});
var builder = services.AddIdentityCore<User>(opt =>
{
opt.Password.RequireDigit = false;
opt.Password.RequiredLength = 2;
opt.Password.RequireNonAlphanumeric = false;
opt.Password.RequireUppercase = false;
// *******************************************************
// for email confirmation
opt.SignIn.RequireConfirmedEmail = true;
// *******************************************************
});
builder = new IdentityBuilder(builder.UserType, typeof(Role), builder.Services);
// AddDefaultTokenProviders() allows the ability to create a token to send to user when they forgot password
builder.AddEntityFrameworkStores<DataContext>().AddDefaultTokenProviders();
// for roles
builder.AddRoleValidator<RoleValidator<Role>>();
builder.AddRoleManager<RoleManager<Role>>();
builder.AddSignInManager<SignInManager<User>>();
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(config["Token:Key"])),
ValidIssuer = config["Token:Issuer"],
ValidateIssuer = true,
ValidateAudience = false
};
});
services.AddAuthorization(options =>
{
options.AddPolicy("RequireAdminRole", policy => policy.RequireRole("Admin"));
options.AddPolicy("ModeratePhotoRole", policy => policy.RequireRole("Admin", "Moderator"));
options.AddPolicy("VipOnly", policy => policy.RequireRole("VIP"));
});
return services;
}
Angular.json 文件的構建部分

我的 Angular 項目中的 Environment.ts
export const environment = { production: false, apiUrl: 'https://localhost:5001/api/' };
我解決了我的問題。 這就是我所做的。
將此行添加到 Startup.cs 中的 Configure()
app.UseStaticFiles();
已移除
.RequireAuthorization() 來自
endpoints.MapControllers().RequireAuthorization();
現在它工作正常,在我的 API 項目中從 wwwroot 運行我的 Ng 應用程序
