参数为实体类时是否有Attribute可用于自定义字段名

[xljiulang]

[JsonPropertyName]，因为KeyValue序列化也是使用system.text.json

[ShmilyChen]

如果我还有Form 的某个字段为 json 文本的离谱需求有相应的特性可以用来标注吗

参考 https://webapiclient.github.io/guide/deformed-interface.html#%E9%80%82%E9%85%8D%E7%95%B8%E5%BD%A2%E6%8E%A5%E5%8F%A3

跟着源码debug了一遍，大概看到是先通过System.Text.Json转换为Josn然后再转为请求参数，所以用了个转换器来折中的解决这个问题

实体类

/// <summary>
/// AccessToken输入参数
/// </summary>
public class AccessTokenInput
{
    /// <summary>
    /// 客户端ID
    /// </summary>
    [JsonPropertyName("client_id")]
    public string ClientId { get; set; }

    /// <summary>
    /// 访问内容
    /// </summary>
   [JsonConverter(typeof(ObjectToStringConverter))]
   public ChatContent Content { get; set; }
}

public record ChatContent(string content)

转换器

public class ObjectToStringConverter : JsonConverter<object>
{
    public override bool CanConvert(Type typeToConvert)
    {
        return typeToConvert.IsClass;
    }

    public override object? Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options)
    {
        var serialize = JsonSerializer.Deserialize<string>(ref reader, options);
        return JsonSerializer.Deserialize(serialize, typeToConvert, options);
    }

    public override void Write(
        Utf8JsonWriter        writer,
        object                objectToWrite,
        JsonSerializerOptions options)
    {
        writer.WriteStringValue(JsonSerializer.Serialize(objectToWrite, options));
    }
}

声明接口

Task<string> SendMsg([FormContent] AccessTokenInput input);
