开发笔记:应用程序在没有读取整个请求主体的情况下完成，.netcore2.1.1

篇首语：本文由编程笔记#小编为大家整理，主要介绍了应用程序在没有读取整个请求主体的情况下完成，.net core 2.1.1相关的知识，希望对你有一定的参考价值。

我创建了一个用户注册控制器来注册用户的存储库设计模式。我的控制器看起来像这样。

[Route("api/[controller]")] public class AuthController : Controller { private readonly IAuthRepository _repo; public AuthController(IAuthRepository repo) { _repo = repo; } [AllowAnonymous] [HttpPost("register")] public async Task Register([FromBody] UserForRegisterDto userForRegisterDto){ // validate request if(!ModelState.IsValid) return BadRequest(ModelState); userForRegisterDto.Username = userForRegisterDto.Username.ToLower(); if(await _repo.UserExists(userForRegisterDto.Username)) return BadRequest("Username is already taken"); var userToCreate = new User{ Username = userForRegisterDto.Username }; var createUser = await _repo.Register(userToCreate, userForRegisterDto.Password); return StatusCode(201); } }

当我使用Postman发送请求时，它会向我提供404未找到的状态代码，并且API会在不读取整个正文的情况下报告请求已完成。

我在Postman的请求看起来像这样。 enter image description here

我已经使用数据传输对象（DTO）来封装数据，我删除了UserForRegisterDto并尝试使用string username和string password，如下所示，但它不起作用。

public async Task Register([FromBody] string username, string password)

UserForRegisterDto看起来像这样。

public class UserForRegisterDto { [Required] public string Username { get; set; } [Required] [StringLength(8, MinimumLength =4, ErrorMessage = "You must specify a password between 4 and 8 characters.")] public string Password { get; set; } }

我为此尝试了许多在线解决方案，但到目前为止还没有解决我的问题。请帮我解决问题，谢谢你提前。我在Ubuntu 18.04上运行这个API

编辑：Startup.cs

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.AddDbContext(x => x.UseSqlite(Configuration.GetConnectionString("DefaultConnection"))); services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1); services.AddCors(); services.AddScoped(); } // This method gets called by the runtime. Use this method to configure the HTTP request pipeline. public void Configure(IApplicationBuilder app, IHostingEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } else { app.UseHsts(); } app.UseCors(x => x.AllowAnyHeader().AllowAnyMethod().AllowAnyOrigin().AllowCredentials()); app.UseMvc(); } }

当客户端发送不满足服务器要求的请求时，经常会出现the application completed without reading the entire request body的错误信息。换句话说，它恰好在进入操作之前发生，导致您无法通过操作体方法中的断点对其进行调试。

[Route("api/[controller]")]
[ApiController]
public class DummyController : ControllerBase
{
    [HttpPost]
    public DummyDto PostTest([FromBody] DummyDto dto)
    {
        return dto;
    }
}

例如，以下发布请求，其中没有Content-Type: application/json标头：

POST https://localhost:44306/api/test HTTP/1.1
Accept : application/json
{ "id":5 }

Microsoft.AspNetCore.Hosting.Internal.WebHost:Information: Request starting HTTP/1.1 POST http://localhost:44306/api/test  10
Microsoft.AspNetCore.Hosting.Internal.WebHost:Information: Request finished in 1.9319ms 404 
Microsoft.AspNetCore.Server.Kestrel:Information: Connection id "0HLGH8R93RPUO", Request id "0HLGH8R93RPUO:00000002": the application completed without reading the entire request body.

HTTP/1.1 404 Not Found
Server: Kestrel
X-SourceFiles: =?UTF-8?B?RDpccmVwb3J0XDIwMThcOVw5LTFcU08uQXV0aFJlYWRpbmdXaXRob3V0RW50aXRlQm9keVxBcHBcQXBwXGFwaVx0ZXN0?=

在localhost中进行调试时，我遇到了一个新的ASP.NET Core 2.1服务，因为我在Startup.Configure中：

if (env.IsDevelopment())
{
     app.UseDeveloperExceptionPage();
}
else
{
     app.UseHttpsRedirection();
}

1.Close all the instances of visual studios, run Developer command prompt with Admin rights.
2.git clean -xfd [Your Repository to remove all dependencies and existing soln file]
3.take the latest build and run . [Make Endpoint AllowAnonymous]

我有同样的错误（即使使用“Content-Type：application / json”），但在动作动词中添加“{id}”，即为

    [HttpPatch]
    [ActionName("Index")]
    [Authorize(Policy = "Model")]
    public async Task Update([FromRoute]int id, int modelId, [FromBody]Device device)

    [HttpPatch("{id}")]
    [ActionName("Index")]
    [Authorize(Policy = "Model")]
    public async Task Update([FromRoute]int id, int modelId, [FromBody]Device device)

 [AllowAnonymous]
 [HttpPost("register")]
 [Route("jsonbody")]
    public async Task Register([FromBody] UserForRegisterDto userForRegisterDto){}

我有相同的错误，检查你可能在AddMvc服务中放入（AutoValidateAntiforgeryTokenAttribute）

services.AddMvc(opt => {
            //Prevent CSF Attake For POST,PUT,DELETE Verb
            //opt.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());
        })
