介绍

为了实现两个json字符串之间的映射，该库会根据关系信息生成新的对象或者集合，也集成了访问三方Api的底层拦截器，帮忙实现自动授权。

接口层

JsonPathConverter.Abstractions

JsonPathConverter.JsonSource.HttpApi.Abstractions

实现层

JsonPathConverter.ColumnMapper.NewObject

json列转换器，主要是实现生成新的json数据的功能。

JsonPathConverter.JsonSoure.HttpApi

json数据来源提供者，该提供者是通过访问Api的方式来获取json数据。

JsonPathConverter.JsonSoure.HttpApi.Token

提供HttpApi调用时获取AccessToken的功能，可以配置OAuth2.0中的（client_credentials、password、authorization_code、refresh_token、urn:ietf:params:oauth:grant-type:device_code），如果没有配置就是调用者的Token

{
    "tokenClient":{
        "IdsHost": "http://ids....",
        "GrantType": "client_credentials",
        "TokenRequest": {
          "Scope": "a b c",
          "ClientId": "abc",
          "ClientSecret": "abc-abc-abc"
        }
    }
}

依赖注入

serviceCollection.AddHttpApiJsonDataProviderWithToken(Configuration.GetSelection("tokenClient").Bind);
// 或者无需Token的项目
serviceCollection.AddHttpApiJsonDataProvider();

serviceCollection.AddColumnMapperNewObject();

业务层调用

IServiceProvider serviceProvider = serviceCollection.BuildServiceProvider();

 using (var scope = serviceProvider.CreateScope())
 {
     IJsonDataProvider jsonDataProvider = scope.ServiceProvider.GetService<IJsonDataProvider>()!;
     JsonPathRoot jsonPathRoot = new JsonPathRoot("$.pages");

    jsonPathRoot.AddJsonPathMapper(new JsonPathMapperRelation { DestinationJsonColumnCode = "PageName", SourceJsonPath = "$.name", RootPath = jsonPathRoot.RootPath });
    jsonPathRoot.AddJsonPathMapper(new JsonPathMapperRelation { DestinationJsonColumnCode = "PageUrl", SourceJsonPath = "$.url", RootPath = jsonPathRoot.RootPath });
    jsonPathRoot.AddJsonPathMapper(new JsonPathMapperRelation { DestinationJsonColumnCode = "PageNamespace", SourceJsonPath = "$.namespace", RootPath = jsonPathRoot.RootPath });


    IJsonRequestSource requestSource = new JsonHttpApiRequestSource(new HttpRequestMessage { Method = HttpMethod.Get, RequestUri = new Uri("https://s.alicdn.com/@xconfig/flasher_classic/manifest") });

    var apiJsonStr = await jsonDataProvider.GetJsonDataAsync(requestSource, default);

    IJsonColumnMapper jsonColumnMapper = scope.ServiceProvider.GetService<IJsonColumnMapper>()!;

    var resultJson = jsonColumnMapper.MapToCollection(apiJsonStr, jsonPathRoot);
}

Json匹配学习

自定义转换

services.AddSingleton(new JsonPropertyFormatFunction
{
     FormatKey = "guid",
     FormatFunction = () => Guid.NewGuid()
});
