我们直接进入主题，使用VS2017开发工具
首先要创建一个WebApi项目，创建完之后，在wwwroot文件下，创建一个文件夹 名字可以随意起 我这里呢就叫做Upload了
ok ！ 然后我们再创建一个控制器 IndexController 代码如下
要知道上传图片都是通过HTTP去请求，服务端从request中读取
???????public class PicData ???????{ ???????????public string Msg { get; set; } ???????} ???????[HttpPost] ???????public async Task<bool> InsertPicture([FromServices]IHostingEnvironment environment) ???????{ ???????????var data = new PicData(); ???????????string path = string.Empty; ???????????var files = Request.Form.Files; ???????????if (files == null || files.Count() <= 0) ???????????{ ???????????????data.Msg = "请选择上传的文件。"; ???????????????return false; ???????????} ???????????//格式限制 ???????????var allowType = new string[] {"image/jpg", "image/png", "image/jpeg"}; ???????????if (files.Any(c => allowType.Contains(c.ContentType))) ???????????{ ???????????????if (files.Sum(c => c.Length) <= 1024 * 1024 * 4) ???????????????{ ???????????????????foreach (var file in files) ???????????????????{ ???????????????????????string strpath = Path.Combine("Upload", DateTime.Now.ToString("MMddHHmmss") + file.FileName); ???????????????????????path = Path.Combine(environment.WebRootPath, strpath); ???????????????????????using (var stream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.ReadWrite)) ???????????????????????{ ???????????????????????????await file.CopyToAsync(stream); ???????????????????????} ???????????????????} ???????????????????data.Msg = "上传成功"; ???????????????????return true; ???????????????} ???????????????else ???????????????{ ???????????????????data.Msg = "图片过大"; ???????????????????return false; ???????????????} ???????????} ???????????else ???????????{ ???????????????data.Msg = "图片格式错误"; ???????????????return false; ???????????} ???????}注意一下这段代码
string strpath = Path.Combine("Upload", DateTime.Now.ToString("MMddHHmmss") + file.FileName);在wwwroot下创建的文件夹，要将Upload替换成你的文件夹名称
然后这还没有完，还要做跨域，要在Startup.cs文件中去改
??????public void ConfigureServices(IServiceCollection services) ???????{ ???????????services.AddMvc(); ???????????services.AddCors(options => ???????????{ ???????????????options.AddPolicy("hehe", p => p.AllowAnyMethod()// 允许任何方法 GET,POST,PUT,DELETE, OPTIONS ???????????????????????.AllowAnyHeader() ??????// 允许任何请求头 ???????????????????????.AllowAnyOrigin() ??????// 允许任何地址 ???????????????); ???????????}); ???????}ConfigureServices方法，然后还有Configure方法
???????public void Configure(IApplicationBuilder app, IHostingEnvironment env) ???????{ ???????????app.UseStaticFiles(); app.UseCors("hehe"); ???????????if (env.IsDevelopment()) ???????????{ ???????????????app.UseDeveloperExceptionPage(); ???????????} ???????????app.UseMvc(); ???????}ok完成了，
然后我们就要去创建Vue项目了，
使用npm创建vue项目，vue init webpack file 我们跳过创建过程
使用npm 引用iview 然后在vue项目中的main.js中引用
import iView from ‘iview‘;import ‘iview/dist/styles/iview.css‘;import locale from ‘iview/dist/locale/en-US‘;Vue.use(iView, { locale });ok,然后我们就在app.vue里面写代码
<template> ?<div id="app"> ???????<Upload action="http://localhost:53688/api/Index"> ???????<Button icon="ios-cloud-upload-outline">Upload files</Button> ???</Upload> ?</div></template>
action：就是api的地址
使用VUE+iView+.Net Core上传图片
