+## 依赖环境
+
+`WebApiclientCore`要求项目的`.NET`版本支持`.NET Standard2.1`，并且具备依赖注入的环境。
+
+## 从 Nuget 安装

+
+## 声明接口
+
+```csharp
+[LoggingFilter]
+[HttpHost("http://localhost:5000/")]
+public interface IUserApi
+{
+    [HttpGet("api/users/{id}")]
+    Task<User> GetAsync(string id);
+
+    [HttpPost("api/users")]
+    Task<User> PostAsync([JsonContent] User user);
+}
+
+public class User
+{ 
+    [JsonPropertyName("account")]
+    public string Account { get; set; } = string.Empty;
+
+    public string Password { get; set; } = string.Empty;
+}
+```
+
+## 注册和配置接口
+
+AspNetCore Startup
+
+```csharp
+public void ConfigureServices(IServiceCollection services)
+{
+    services.AddHttpApi<IUserApi>().ConfigureHttpApi(o =>
+    {
+        o.UseLogging = Environment.IsDevelopment();
+        o.HttpHost = new Uri("http://localhost:5000/");
+
+        // o.JsonSerializeOptions -> json 序列化选项
+        // o.JsonDeserializeOptions -> json 反序列化选项
+        // o.KeyValueSerializeOptions -> 键值对序列化选项
+        // o.XmlSerializeOptions -> xml 序列化选项
+        // o.XmlDeserializeOptions -> xml 反序列化选项
+        // o.GlobalFilters -> 全局过滤器集合
+    });
+}
+```
+
+Console
+
+```csharp
+public static void Main(string[] args)
+{
+    // 无依赖注入的环境需要自行创建
+    var services = new ServiceCollection();
+    services.AddHttpApi<IUserApi>().ConfigureHttpApi(o =>
+    {       
+        o.UseLogging = Environment.IsDevelopment();
+        o.HttpHost = new Uri("http://localhost:5000/");
+    });
+}
+```
+
+## 全局配置接口
+
+全局配置可以做为所有接口的默认初始配置，当项目中有很多接口时就很有用。
+
+```csharp
+public void ConfigureServices(IServiceCollection services)
+{
+    services.AddWebApiClient().ConfigureHttpApi(o =>
+    {
+        o.JsonSerializeOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
+        o.JsonDeserializeOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
+        o.KeyValueSerializeOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
+    });
+}
+```
+
+## 注入和调用接口
+
+在Scoped或Transient服务中注入
+
+```csharp
+public class YourService
+{
+    private readonly IUserApi userApi;
+    public YourService(IUserApi userApi)
+    {
+        this.userApi = userApi;
+    }
+
+    public async Task GetAsync()
+    {
+        // 调用接口
+        var user = await this.userApi.GetAsync(id:"id001");
+        ...
+    }
+}
+```
+
+在Singleton服务中注入
+
+```csharp
+public class YourService
+{
+    private readonly IServiceScopeFactory serviceScopeFactory;
+    public YourService(IServiceScopeFactory serviceScopeFactory)
+    {
+        this.serviceScopeFactory = serviceScopeFactory;
+    }
+
+    public async Task GetAsync()
+    {
+        // 从创建的scope中获取接口实例
+        using var scope = this.serviceScopeFactory.CreateScope();
+        var userApi = scope.ServiceProvider.GetRequiredService<IUserApi>();
+        var user = await userApi.GetAsync(id:"id001");
+        ...
+    }
+}
+```
