c# - NGINX 在我的 Web API 中没有正确运行请求
问题描述
我是开发 Web API 的新手，我正试图将我的小型 Web API 发布到我的 VPS 中。问题是我已经设置好了。在这篇文章的后面，我将向您展示 Nginx 配置和所有必要的信息。我遇到的主要问题是，例如，当我调用我的获取 OAuth 令牌请求时，它返回 200 OK 但是当我将承载令牌放入每个请求中时，我将执行 API 总是返回 500 状态代码。我已按照 Microsoft 指南设置 .NET Web API，但我仍然遇到这些问题。我该如何解决这个问题？提前致谢。
获取 OAuth 令牌
使用该令牌获取所有用户请求
API 的 Startup.cs（您可以找到我添加了来自官方 Microsoft Docs 的行）
namespace IncidentManagerAPI
{
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.Configure<ForwardedHeadersOptions>(options =>
{
options.KnownProxies.Add(IPAddress.Parse("141.94.23.122"));
});
services.AddMvc();
services.Configure<ForwardedHeadersOptions>(options =>
{
options.ForwardedHeaders =
ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto;
});
services.AddScoped<IUserInterface, UserService>();
services.AddScoped<ICompanyInterface, CompanyService>();
//services.AddControllers();
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new OpenApiInfo { Title = "Incident Manager API", Version = "v1", Description = "Welcome to the Incident Manager API, here you will be able to test all API requests for debugging." });
c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
Description = "Authorization header using the Bearer scheme. Example: \"Authorization: Bearer {token}\"",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
Scheme = "bearer",
BearerFormat = "JWT"
});

new OpenApiSecurityScheme
{

},
new List<string>()
}
});
});
services.AddEntityFrameworkNpgsql().AddDbContext<PostgreSQLContext>(opt =>
opt.UseNpgsql(Configuration.GetConnectionString("PostgreSQLConnection")));
services

.AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", options => { })

{

ValidAudience = "testuser",
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("testpassword")),
ClockSkew = TimeSpan.Zero
};
});
services.AddAuthorization(options =>
{
options.DefaultPolicy = new AuthorizationPolicyBuilder(JwtBearerDefaults.AuthenticationScheme).RequireAuthenticatedUser().Build();
options.AddPolicy("BasicAuthentication", new AuthorizationPolicyBuilder("BasicAuthentication").RequireAuthenticatedUser().Build());
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
});
app.UseAuthentication();
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseSwagger();
app.UseSwaggerUI(c =>
{
c.SwaggerEndpoint("/swagger/v1/swagger.json", "MyAPI");
c.RoutePrefix = string.Empty;
});
app.UseHttpsRedirection();
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();

}
}
}

编辑：
我在 C# 中启用了日志，但仍然不知道如何解决问题：

更新：
问题是我在数据库模式中没有权限。
解决方案
NGINX 配置似乎没问题，我不是 C# 人，所以不确定那部分。
如果您在应用程序错误日志中没有看到值得修复的内容，则可能是 NGINX。您可以发布 NGINX 错误日志中的最后几行吗？
