我正在开发 ASP.NET Web Api，我编写了一些代码来测试我的一个 API 控制器。但是当我调用该方法时，chrome 会发送以下内容：
http://localhost:44333/api/GradesReader/getTest/net::ERR_CONNECTION_RESET jquery.min.js:2
这是我的 API 项目 Startup.cs：
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(x => x.Filters.Add(new AuthorizeFilter())).AddXmlSerializerFormatters()
.AddXmlDataContractSerializerFormatters();
//For the personal exception handling...
//services.AddMvc(config =>
//{
// config.Filters.Add(typeof(DiaryExceptionFilter));
//});
services.AddDbContext<DiaryDataContext>();
services.AddIdentity<IdentityUser, IdentityRole>()
.AddEntityFrameworkStores<DiaryDataContext>()
.AddDefaultTokenProviders();
services.ConfigureApplicationCookie(opt =>
{
opt.Events = new CookieAuthenticationEvents
{
OnRedirectToLogin = redirectContext =>
{
redirectContext.HttpContext.Response.StatusCode = 401;
return Task.CompletedTask;
},
OnRedirectToAccessDenied = redirectContext =>
{
redirectContext.HttpContext.Response.StatusCode = 401;
return Task.CompletedTask;
}
};
});
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "My API", Version = "v1" });
});
services.AddCors(); //Ezt raktuk bele!
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
//app.UseExceptionHandler("/Home/Error");
//// The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
//app.UseHsts();
app.UseExceptionHandler(
options =>
{
options.Run(async context =>
{
context.Response.StatusCode = 500;
context.Response.ContentType = "application/json";
//var ex = context.Features.Get<IExceptionHandlerFeature>();
//if (ex != null)
//{
// await context.Response.WriteAsync(ex.Error.Message);
//}
});
});
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseRouting();
app.UseAuthentication();
app.UseAuthorization();
//app.UseEndpoints(endpoints =>
//{
// endpoints.MapControllerRoute(
// name: "default",
// pattern: "{controller=Home}/{action=Index}/{id?}");
//});
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
});
app.UseCors(opt => opt.WithOrigins("https://localhost:44333/"));
}
}
方法如下：
[HttpGet("getTest")]
public string GetTest()
{
return "TEST";
}
这是 html：
`
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="lib/jquery/dist/jquery.min.js"></script>
<script src="js/jquery.unobtrusive-ajax.min.js"></script>
<script>
$(document).ready(function () {
$("#myButton").click(function () {
$.ajax({
url: 'http://localhost:44333/api/GradesReader/getTest/',
type: 'GET',
/*cache: false,*/
/*dataType = 'json',*/
success: function (result) {
console.log(result);
}
});
});
});
</script>
</head>
<body>
<h1>Test API</h1>
<input type="button" id="myButton" value="Show Grades" />
</body>
</html>`
url: 'http://localhost:44333/api/GradesReader/getTest/',
在您的应用程序中，您将其配置为使用
httpshttpnet::ERR_CONNECTION_RESET要解决此问题，请将 URL 更改为使用
https url: 'https://localhost:44333/api/GradesReader/getTest/',
