Question

我正在ASP.NET Core 2.1 Web API和React中编写应用程序。我的服务器位于localhost：5000上，我的客户端位于localhost：3000上。我想用axios发送发帖请求，但是在浏览器控制台中我看到错误：

OPTIONS https://localhost:5001/api/auth/login 0 ()
Uncaught (in promise) Error: Network Error
at createError (createError.js:16)
at XMLHttpRequest.handleError (xhr.js:87)

在我的Web API中，我尝试添加CORS，但它似乎不起作用。我添加：

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors();
    services.AddMvc();
    ...
}

并且：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseCors(options =>
        options
        .AllowAnyOrigin()
        .AllowAnyMethod()
        .AllowAnyHeader()
        .AllowCredentials());
    ...
    app.UseMvc();
}

这是我的帖子请求：

const response = await axios({
        method: 'post',
        url: 'http://localhost:5000/api/auth/login',

        data: {
            userName: this.state.controls.login.value,
            password: this.state.controls.password.value
        }
    });

请求后的服务器控制台：

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
      Request starting HTTP/1.1 OPTIONS http://localhost:5000/api/auth/login
info: Microsoft.AspNetCore.Cors.Infrastructure.CorsService[4]
      Policy execution successful.

      Request finished in 4.253ms 204

      Request starting HTTP/1.1 POST http://localhost:5000/api/auth/login application/json;charset=UTF-8 52

      Policy execution successful.

      Connection id "0HLG4CH3JIV16", Request id "0HLG4CH3JIV16:00000002": the application completed without reading the entire request body.

当我使用邮递员时，一切都很好。我从服务器收到带令牌的json。

好的，我解决了我的问题。我只是不知道我应该删除“ app.UseHttpsRedirection（）;”。
