如果有某些接口本库尚未支持,你可按照下面的示例自行扩展:
/* 继承 WechatTenpayRequest 实现自定义请求类 */
public class MyFakeRequest : WechatTenpayRequest
{
[Newtonsoft.Json.JsonProperty("my_fake_props")]
[System.Text.Json.Serialization.JsonPropertyName("my_fake_props")]
public string MyFakeProps { get; set; }
}
/* 继承 WechatTenpayResponse 实现自定义响应类 */
public class MyFakeResponse : WechatTenpayResponse
{
[Newtonsoft.Json.JsonProperty("my_fake_props")]
[System.Text.Json.Serialization.JsonPropertyName("my_fake_props")]
public string MyFakeProps { get; set; }
}
/* 扩展 WechatTenpayClient 方法 */
public static class MyFakeClientExtensions
{
public static async Task<MyFakeResponse> ExecuteMyFakeAsync(this WechatTenpayClient client, MyFakeRequest request, CancellationToken cancellationToken = default)
{
if (client is null) throw new ArgumentNullException(nameof(client));
if (request is null) throw new ArgumentNullException(nameof(request));
IFlurlRequest flurlReq = client
.CreateRequest(request, HttpMethod.Post, "my-fake-url")
.SetQueryParam("access_token", request.AccessToken);
return await client.SendRequestWithJsonAsync<MyFakeResponse>(flurlReq, request, cancellationToken);
}
}
同样地,你也可自行扩展回调通知事件的敏感数据模型:
/* 实现自定义的 JSON 格式的回调通知事件敏感数据 */
public class MyFakeEvent : WechatTenpayEvent.Types.IDecryptedResource
{
[Newtonsoft.Json.JsonProperty("my_fake_props")]
[System.Text.Json.Serialization.JsonPropertyName("my_fake_props")]
public string MyFakeProps { get; set; }
}
如果你扩展的自定义请求或响应模型中包含敏感信息字段,并希望可以通过本库提供的 EncryptRequestSensitiveProperty()
和 DecryptResponseSensitiveProperty()
两个扩展方法来实现自动加、解密,那么你需要在定义模型时额外指定特性:
[WechatTenpaySensitive]
public class MyFakeRequest : WechatTenpayRequest
{
[Newtonsoft.Json.JsonProperty("my_fake_props")]
[System.Text.Json.Serialization.JsonPropertyName("my_fake_props")]
[WechatTenpaySensitiveProperty("my_scheme", "my_alg")]
public string MyFakeProps { get; set; }
}
[WechatTenpaySensitive]
public class MyFakeResponse : WechatTenpayResponse
{
[Newtonsoft.Json.JsonProperty("my_fake_props")]
[System.Text.Json.Serialization.JsonPropertyName("my_fake_props")]
[WechatTenpaySensitiveProperty("my_scheme", "my_alg")]
public string MyFakeProps { get; set; }
}
