.net core 生成二维码

其实生成二维码的组件有很多种，如：QrcodeNet，ZKWeb.Fork.QRCoder，QRCoder等

我选QRCoder，是因为小而易用、支持大并发生成请求、不依赖任何库和网络服务。

既然是.net core 那当然要用依赖注入，通过构造函数注入到控制器。

软件版本

Asp.net Core:2.0

QRCoder:1.3.3(开发时最新)

项目结构

Snai.QRCode.Api  Asp.net core 2.0 Api网站

项目实现

新建Snai.QRCode解决方案，在解决方案下新建一个名Snai.QRCode.Api Asp.net core 2.0 Api网站

在 依赖项 右击 管理NuGet程序包 浏览 找到 QRCoder 版本1.3.3 下载安装

由于使用依赖注入，依赖抽象不依赖实现，所以要建一个实现二维码的接口

在项目添加 Common 文件夹，在文件夹添加 IQRCode 二维码接口，接口定义 GetQRCode 二维码方法，代码如下

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Threading.Tasks;

namespace Snai.QRCode.Api.Common
{
    public interface IQRCode
    {
        Bitmap GetQRCode(string url, int pixel);
    }
}

在 Common 目录下添加 RaffQRCode 类，继承IQRCode接口实现GetQRCode类，代码如下

using QRCoder;
using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Threading.Tasks;

namespace Snai.QRCode.Api.Common
{
    public class RaffQRCode : IQRCode
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="url">存储内容</param>
        /// <param name="pixel">像素大小</param>
        /// <returns></returns>
        public Bitmap GetQRCode(string url, int pixel)
        {
            QRCodeGenerator generator = new QRCodeGenerator();
            QRCodeData codeData = generator.CreateQrCode(url, QRCodeGenerator.ECCLevel.M, true);
            QRCoder.QRCode qrcode = new QRCoder.QRCode(codeData);

            Bitmap qrImage = qrcode.GetGraphic(pixel, Color.Black, Color.White, true);

            return qrImage;
        }
    }
}

修改Startup.cs代码，注入RaffQRCode类到容器

代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;
using Snai.QRCode.Api.Common;

namespace Snai.QRCode.Api
{
    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.AddSingleton<IQRCode, RaffQRCode>();
            services.AddMvc();
        }

        // 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();
            }

            app.UseMvc();
        }
    }
}

在Controllers 下添加QRCodeController Api空的控制器，采用构造函数依赖，引入RaffQRCode类

添加GetQRCode(string url, int pixel)方法，加入HttpGet("/api/qrcode")路由地址，方法里使用_iQRCode.GetQRCode(url, pixel)生成二维码再输出
