在 .net core 中使用 swagger 生成接口文檔跟在 asp.net 中使用方式同樣,但把 swagger 添加到項目中不在生成SwaggerConfig.cs 文件 ,需本身配置。

項目引入Swagger

我這裏安裝的是VS2017, 固然 VS Code也是能夠的。 Nuget安裝Swagger的命令是:

Install-Package Swashbuckle.AspNetCore -Pre

注意：Nuget包管理添加時必定要注意選擇的時候 選擇 Swashbuckle.AspNetCore 默認的 Swashbuckle 不支持 asp.net core

基於asp.net core 的中間件機制, Swagger也須要加入到中間件服務的列表中, 這樣才能夠啓用Swagger。在 Startup.cs 中的 ConfigureServices 跟 Configure 方法添加 Swagger  代碼以下：

 public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
            //添加Swagger.
            services.AddSwaggerGen(c =>
            {
                c.SwaggerDoc("v1", new Info { Title = "DemoAPI", 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();
            }

            app.UseMvc();
            //配置Swagger
            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "DemoAPI V1");
            });
        }

從新編譯後訪問,效果以下：

 

修改Web API項目首頁重定向

根據須要，找到項目 Properties下的 launchSettings.json 文件,好比修改IIS Express節點下的launchUrl，將其改成下圖中的值,這樣啓動時就重定向到指定的地址

漢化 swagger

在Startup.cs 類方法 Configure 中啓用 讀取靜態資源文件,並添加 UseSwaggerUI 讀取js文件

  public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseMvc();
            app.UseStaticFiles();

            //配置Swagger
            app.UseSwagger();
            app.UseSwaggerUI(c =>
            {
                c.SwaggerEndpoint("/swagger/v1/swagger.json", "DemoAPI V1");
                //加載漢化的js文件，注意 swagger.js文件屬性必須設置爲「嵌入的資源」。
                c.InjectOnCompleteJavaScript("/Scripts/swagger.js");
            });
        }

js文件源碼：

'use strict';

/** 
 * Translator for documentation pages. 
 * 
 * To enable translation you should include one of language-files in your index.html 
 * after <script src='lang/translator.js' type='text/javascript'></script>. 
 * For example - <script src='lang/ru.js' type='text/javascript'></script> 
 * 
 * If you wish to translate some new texsts you should do two things: 
 * 1. Add a new phrase pair ("New Phrase": "New Translation") into your language file (for example lang/ru.js). It will be great if you add it in other language files too. 
 * 2. Mark that text it templates this way <anyHtmlTag data-sw-translate>New Phrase</anyHtmlTag> or <anyHtmlTag data-sw-translate value='New Phrase'/>. 
 * The main thing here is attribute data-sw-translate. Only inner html, title-attribute and value-attribute are going to translate. 
 * 
 */
window.SwaggerTranslator = {
    _words: [],

    translate: function () {
        var $this = this;
        $('[data-sw-translate]').each(function () {
            $(this).html($this._tryTranslate($(this).html()));
            $(this).val($this._tryTranslate($(this).val()));
            $(this).attr('title', $this._tryTranslate($(this).attr('title')));
        });
    },

    _tryTranslate: function (word) {
        return this._words[$.trim(word)] !== undefined ? this._words[$.trim(word)] : word;
    },

    learn: function (wordsMap) {
        this._words = wordsMap;
    }
};

 效果如圖所示：

顯示註釋：項目屬性設置生成xml文件路徑，默認生成在bin目錄

修改Startup以下：

public void ConfigureServices(IServiceCollection services)
{
       services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
       //添加Swagger.
       services.AddSwaggerGen(c =>
       {
           c.SwaggerDoc("v1", new Swashbuckle.AspNetCore.Swagger.Info { Title = "My API", Version = "v1" });
           //添加xml文件
           c.IncludeXmlComments(Path.Combine(Directory.GetCurrentDirectory(), "WebAPI.XML"));
        });
}

在控制器中添加註釋，效果如圖：

最終效果以下：
