如何在 .Net Core API 中实现上传表单？

用户10863293

我创建了一个.Net Core API（我使用了swagger）。

我创建了一个控制器以上传图片以将其链接到项目。

.cs :

[HttpPut("[Action]/{id}")]
public async Task<ActionResult> Link(int id, IFormFile file)
{
    var item = await _context.Item.FirstOrDefaultAsync(t => t.Id == id);
    if (item == null)
    {
        return BadRequest("item null");
    }

    using (var memoryStream = new MemoryStream())
    {
        await file.CopyToAsync(memoryStream);
        // code to link
        return Ok(file);
    }
}

我的问题是，如果我想测试它是否有效，我必须使用邮递员，但我想在我的 api 中测试它。

我的问题有解决方案吗？目前它看起来像这样：

对于Swashbuckle.AspNetCorewith4.0.1和Swashbuckle.AspNetCore.Swaggerwith 4.0.1，它支持IFormFilewith swagger/index.html。

详细步骤：

安装包Swashbuckle.AspNetCore带4.0.1和Swashbuckle.AspNetCore.Swagger带4.0.1

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.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
        services.AddSwaggerGen(c =>
        {
            c.SwaggerDoc("v1", new Info { Title = "My API", Version = "v1" });
        });

    }

    // 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
        {
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

        app.UseHttpsRedirection();
        // Enable middleware to serve generated Swagger as a JSON endpoint.
        app.UseSwagger();
        // Enable middleware to serve swagger-ui (HTML, JS, CSS, etc.),
        // specifying the Swagger JSON endpoint.
        app.UseSwaggerUI(c =>
        {
            c.SwaggerEndpoint("/swagger/v1/swagger.json", "My API V1");
        });

        app.UseMvc();
    }
}

ApiController

[Route("api/[controller]")]
[ApiController]
public class ValuesController : ControllerBase
{
    [HttpPut("[Action]/{id}")]
    public async Task<ActionResult> Link(int id, IFormFile file)
    {
        return Ok(id);
    }
}
