我创建了一个用户注册控制器,以使用存储库设计模式注册用户。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<IActionResult> 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,它会显示404找不到状态代码,并且API报告请求已完成而没有读取整个正文。
我已经使用数据传输对象(DTO)封装了数据,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<IActionResult> 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,没有任何解决方案可以解决我的问题。请帮助我解决问题,在此先谢谢您。我正在Ubuntu 18.04上运行此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<DataContext>(x => x.UseSqlite(Configuration.GetConnectionString("DefaultConnection")));
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddCors();
services.AddScoped<IAuthRepository, AuthRepository>();
}
// 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();
}
}

setContentView(...)
的错误信息通常在客户端发送不满足服务器要求的请求时发生。换句话说,它只是在进入动作之前发生,导致您无法通过动作主体中的断点来调试它。
例如,假设服务器上的一种操作方法:
the application completed without reading the entire request body
这里的[Route("api/[controller]")]
[ApiController]
public class DummyController : ControllerBase
{
[HttpPost]
public DummyDto PostTest([FromBody] DummyDto dto)
{
return dto;
}
}
是一个虚拟类,用于保存信息:
DummyDto
当客户发送有效载荷格式不正确的请求
例如,以下发布请求,其中没有public class DummyDto
{
public int Id { get; set; }
}
标头:
Content-Type: application/json
将导致类似的错误信息:
POST https://localhost:44306/api/test HTTP/1.1
Accept : application/json
{ "id":5 }
,来自服务器的响应将为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.

404
关于您描述的问题,我建议您检查以下列表:

Content-Length: 0
的请求?确保已检查标题Content-Type: application/json
以显示当您向服务器发送请求时它发送的内容。答案 1 :(得分:4)
在本地主机上调试时,在新的ASP.NET Core 2.1服务中发生了这件事,因为我在Startup.Configure中:
app.UseHttpsRedirection();
我在本地调试时停用了此设置:
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
else
{
app.UseHttpsRedirection();
}

可能有多种原因,其中可能是:–在Visual Studio中进行缓存-
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]

我花了几个小时。我的问题是我有:
[HttpPut("{matchGuidStr}/join")]
public async Task<IActionResult> JoinNewMatch (string matchGuidStr) {
代替:
[HttpPut("{matchGuidStr}/join")]
public async Task<IActionResult> JoinNewMatch (string matchGuidStr, [FromBody] Payloads.JoinGamePayload payload) {
基本上,我的路线根本不关心请求主体(故意),但是我仍然需要将其作为参数传递。 y!

我遇到了同样的错误(即使使用“ Content-Type:application / json”也是如此),但是在动作动词中添加“ {id}”对我来说却很有效 即从
更改 [HttpPatch]
[ActionName("Index")]
[Authorize(Policy = "Model")]
public async Task<JsonResult> Update([FromRoute]int id, int modelId, [FromBody]Device device)
到
[HttpPatch("{id}")]
[ActionName("Index")]
[Authorize(Policy = "Model")]
public async Task<JsonResult> Update([FromRoute]int id, int modelId, [FromBody]Device device)
(asp.net核心2.1)

您可以通过添加请求方法[Route(“ jsonbody”)]
尝试一下吗? [AllowAnonymous]
[HttpPost("register")]
[Route("jsonbody")]
public async Task<IActionResult> Register([FromBody] UserForRegisterDto userForRegisterDto){}

我有同样的错误, 检查您是否可以将(AutoValidateAntiforgeryTokenAttribute)放入AddMvc Services
services.AddMvc(opt => {
//Prevent CSF Attake For POST,PUT,DELETE Verb
//opt.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());
})

我这样解决了。来自
namespace AuthenticationService.Controllers
{
[Route("api/authentication")]
[ApiController]
public class AuthenticationController : ControllerBase
{
[HttpPost("/token")]
public IActionResult GenerateToken([FromBody] LoginRest loginRest)
{
附加到[Route("api/authentication/")]
到/
。我删除的[HttpPost("token")]
处的斜杠。

在远程Dotnet 2.2
计算机上运行NGinx
和Ubuntu 18.04
时遇到相同的问题,得到了:
在每个API调用上..无需阅读整个请求正文即可完成应用程序
。对我而言,解决方案是通过让我们加密通过CERTBot在主机上安装SSL证书,因为Dotnet
不允许未加密的流量。
希望这对某人有帮助

就我而言,根据实施情况,使用不正确的方法有时会导致此问题。例如尝试使用 POST
而不是 PATCH
