ABPVNext问题集锦-SwaggerUI的配置问题，配置Schema自动展开

首先感谢以下兄弟：虚心、老暮、你被写在我的歌里等兄弟

一，ABP框架中，运行的SwaggerUI中，默认情况下，不管Post还是Get等请求接口的Schema默认情况是折叠的，前端接入接口时需要一个个手动点开，如果参数过多比如100个参数 要点100次，使用不是太方便，或那种又有查询、又有新增，并且json里面各种套，对象里面有数组，数组里面套数据，  这种参数就很多了，如下图所示，如何单击Schema时展示的属性及子属性自动展开？

 查看swagger源码，如下图所示

 得到启发，进行如下配置：

 说明：如果嵌套的子属性深度比较大，那么可直接设置：options.DefaultModelExpandDepth(99)，加到99就基本上不用配置了，配置后的效果图：

二，SwaggerUI知识扩展

常用扩展属性说明

Swagger UI提供了多种配置选项，可以通过SwaggerUIOptions类来自定义Swagger UI界面的行为。SwaggerUIOptionsExtensions是Swagger UI的一个扩展，它提供了一组方法来进一步配置Swagger UI。以下是一些常见的配置项及其说明：

• DisplayOperationId: 决定是否在Swagger UI中显示操作ID。操作ID是API操作的唯一标识符。

uiConfig.DisplayOperationId(true);

• DefaultModelsExpandDepth: 设置默认展开模型的深度。这个值决定了在Swagger UI中模型的嵌套对象默认展开的层数。

uiConfig.DefaultModelsExpandDepth(1); // 默认展开一层嵌套对象

• DefaultModelExpandDepth: 这个配置项与DefaultModelsExpandDepth类似，也用于设置默认展开模型的深度。

uiConfig.DefaultModelExpandDepth(1); // 默认展开一层嵌套对象

• DefaultModelRendering: 控制Swagger UI中模型的默认渲染方式。

uiConfig.DefaultModelRendering(ModelRendering.EXAMPLE); // 显示模型示例

• DeepLinking: 允许在Swagger UI中直接点击链接以打开API操作。

uiConfig.DeepLinking(true);

• DocExpansion: 设置文档展开的默认行为。

uiConfig.DocExpansion(DocExpansion.NONE); // 不自动展开文档

 

• MaxDisplayedTags: 设置Swagger UI中显示的最大标签数。

uiConfig.MaxDisplayedTags(10); // 最多显示10个标签

• OperationsSorter: 设置Swagger UI中API操作的排序方式。

uiConfig.OperationsSorter(OperationsSorter.ALPHA); // 按字母顺序排序

• TagsSorter: 设置Swagger UI中标签的排序方式。

uiConfig.TagsSorter(TagsSorter.ALPHA); // 按字母顺序排序

• ValidatorUrl: 设置或禁用Swagger UI中的在线验证器。

uiConfig.ValidatorUrl("https://online.swagger.io/validator");
请注意，Swagger UI的配置选项可能会随着版本的更新而变化。

 全配置如下图所示

三，SwaggerUI配置写在appsetting.json文件

 程序启动项目中配置：

 这样配置后，配置项的值可以在appsetting.json中动态配置

示例代码

  "SwaggerUI": {
    "RoutePrefix": "swagger",
    "ConfigObject": {
      "Urls": [
        {
          "Url": "/swagger/v1/swagger.json",
          "Name": "V1 Docs"
        }
      ],
      "DeepLinking": true,
      "DisplayOperationId": false,
      "DefaultModelsExpandDepth": -1,
      "DefaultModelExpandDepth": 99,
      "DefaultModelRendering": "example",//另外一种模式：model
      "DocExpansion": "list",
      "Filter": "",
      "ShowExtensions": true
    }
  },

       Configure<SwaggerUIOptions>(c =>
       {
           configuration.Bind("SwaggerUI", c);
           ////SupportedSubmitMethods属性定义了Swagger UI中允许提交的HTTP方法类型。将其设置为空数组将隐藏所有HTTP方法的提交按钮。
           //c.ConfigObject.SupportedSubmitMethods = new SubmitMethod[] { };
           ////AdditionalItems是一个字典，允许你添加任何额外的键值对。在这个例子中，添加了一个键为"swaggerUIFoo"，值为"bar"的项。这些自定义项可以用来扩展Swagger UI的功能或提供一些自定义的配置
           //c.ConfigObject.AdditionalItems.Add("swaggerUIFoo", "bar");
       });
