[英]Unable to post values from angular service to Web API in asp.net core angular
我正在研究asp.net core(2.1)角度項目,這里我將參數從角度服務傳遞到Web API,但沒有在API中獲得這些值。
下面是我的代碼,當我為Web API使用單獨的項目時,它運行良好。 現在,由於我在asp.net核心項目本身中創建了一個控制器,因此無法在API參數列表中獲取發布的值。
我是否需要添加/更改一些設置以從角度服務到API調用獲取值?
角度服務:
getSortedPagedResults(filters): Observable<any> {
debugger;
return this._http.post(this.myAppUrl + 'api/Employee/EmployeesServerSide', filters);
}
API:
[HttpPost]
[Route("api/Employee/EmployeesServerSide")]
public IEnumerable<Users> EmployeesServerSide(Filters filters)
{
return objemployee.GetUsersServerSide(filters);
}
啟動課程:
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddSpaStaticFiles(configuration =>
{
configuration.RootPath = "ClientApp/dist";
});
services.Configure<CookiePolicyOptions>(options =>
{
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddCors(o => o.AddPolicy("CorsPolicy", builder =>
{
builder
.AllowAnyMethod()
.AllowAnyHeader()
//.WithOrigins("http://localhost:4200")
.AllowCredentials();
}));
services.AddSignalR();
services.Configure<FormOptions>(x =>
{
x.ValueLengthLimit = int.MaxValue;
x.MultipartBodyLengthLimit = int.MaxValue; // In case of multipart
});
}
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseCors("CorsPolicy");
app.UseSignalR(routes =>
{
routes.MapHub<NotifyHub>("/notify");
});
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseSpaStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller}/{action=Index}/{id?}");
});
app.UseSpa(spa =>
{
spa.Options.SourcePath = "ClientApp";
if (env.IsDevelopment())
{
spa.Options.StartupTimeout = new TimeSpan(0, 0, 100);
spa.UseAngularCliServer(npmScript: "start");
}
});
}
在API方面,使用FromBody
public IEnumerable<Users> EmployeesServerSide([FromBody] Filters filters)
}
