【中文标题】NGINX 在我的 Web API 中没有正确运行请求【英文标题】：NGINX not running properly requests in my Web API 【发布时间】：2021-05-04 08:57:28 【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（你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"
);
c.AddSecurityRequirement(new OpenApiSecurityRequirement
new OpenApiSecurityScheme
Reference = new OpenApiReference Type = ReferenceType.SecurityScheme, Id = "Bearer"
,
new List<string>()
);
);
services.AddEntityFrameworkNpgsql().AddDbContext<PostgreSQLContext>(opt =>
opt.UseNpgsql(Configuration.GetConnectionString("PostgreSQLConnection")));
services
.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddScheme<AuthenticationSchemeOptions, BasicAuthenticationHandler>("BasicAuthentication", options => )
.AddJwtBearer(options =>
options.SaveToken = true;
options.TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters()
ValidIssuer = "incidentmanagerapi",
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();
);

我已经启用了 C# 中的日志，但仍然不知道如何解决问题：

更新：
问题是我在数据库架构中没有权限。
【问题讨论】：
【参考方案1】：NGINX 配置似乎没问题，我不太会 C#，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？
【讨论】：
刚刚在nginx的access.log中找到了这个：controlc.com/230c8ab9/etc/nginx/error.log 文件中有什么内容吗？
没什么奇怪的，但谢谢你告诉我。以上是关于NGINX 在我的 Web API 中没有正确运行请求的主要内容，如果未能解决你的问题，请参考以下文章
