（二）集成Swagger接口文檔分組配置.net core

（一）回顧：

上一篇為大家介紹了在.NET Core中如何集成Swagger的介紹，想想集成操作其實非常簡單便捷，實質就三個步驟：

（1）在項目中執行nuget命令，拉取Swagger包到項目：Install-package Swashbuckle.AspNetCore

（2）在ConfigureServices方法中新增如下代碼

#region Swagger
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new Info
        {
            Version = "v1.1.0",
            Title = "Swagger WebAPI",
            Description = "XXX項目API文檔",
            TermsOfService = "None",
            Contact = new Swashbuckle.AspNetCore.Swagger.Contact
            {
                Name = "XXX項目",
                Email = "[e-mail]"
            ,
                Url = "https://www.cnblogs.com/NBIDataVis/"
            }
        });
        // 為 Swagger JSON and UI設置xml文檔注釋路徑
        var basePath = Path.GetDirectoryName(typeof(Program).Assembly.Location);
        var xmlPath = Path.Combine(basePath, "CoreWebAPI.xml");
        //如果需要顯示控制器注釋只需將第二個參數設置為true
        c.IncludeXmlComments(xmlPath, true);
    });
#endregion

（3）在Configure方法中新增如下代碼

#region Swagger
    app.UseSwagger();
    app.UseSwaggerUI(c =>
    {
      c.SwaggerEndpoint("/swagger/v1/swagger.json", "ApiDocument V1");
    });
#endregion

（二）問題：

通常一個項目中有很多的功能模塊，每個功能模塊又可能對應很多的接口，如果所有的接口都在一個列表顯示，顯然是比較混亂的，不便於調用方閱讀和查找。

當然Swagger為我們已經考慮到了這一點，它能支持分組顯示，具體怎么做呢，請看下面的配置：

（三）Swagger分組文檔配置：

（1）在ConfigureServices方法中新增如下代碼

#region Swagger
    services.AddSwaggerGen(c =>
    {
        c.SwaggerDoc("v1", new Info
        {
            Version = "v1.1.0",
            Title = "Swagger WebAPI",
            Description = "XXX項目API文檔",
            TermsOfService = "None",
            Contact = new Swashbuckle.AspNetCore.Swagger.Contact
            {
                Name = "XXX項目",
                Email = "[e-mail]"
            ,
                Url = "https://www.cnblogs.com/NBIDataVis/"
            }
        });
        
        c.SwaggerDoc("User", new Info { Title = "用戶模塊", Version = "User" });   //分組顯示
        c.SwaggerDoc("Project", new Info { Title = "項目模塊", Version = "Project" });   //分組顯示

        var basePath = Path.GetDirectoryName(typeof(Program).Assembly.Location);
        var xmlPath = Path.Combine(basePath, "CoreWebAPI.xml");
        c.IncludeXmlComments(xmlPath, true);
    
    });
#endregion

（2）在Configure方法中新增如下代碼

#region Swagger
    app.UseSwagger();
    app.UseSwaggerUI(c =>
    {
        c.SwaggerEndpoint("/swagger/v1/swagger.json", "ApiHelp V1");
        c.SwaggerEndpoint("/swagger/User/swagger.json", "用戶模塊");  //分組顯示
        c.SwaggerEndpoint("/swagger/Project/swagger.json", "項目模塊");  //分組顯示
    });
#endregion

（3）在Controller類上指定分組名：
