C# 如何将JSON发送到使用模型作为HTTPPOST的inputParam的WEBAPI中

我在HTTPPOST方法中为输入参数定义了一个模型，如下所示

public ActionResult<JObject> Post([FromBody] APIInputObject apiInputObject)

public class APIInputObject
{
    public string ApiKey { get; set; }
    public Brand Brand { get; set; }
    public string Query { get; set; }
    public string Locale { get; set; } = "SE";
    public string UseFormatter { get; set; }
}

public class Consumer
{
    public string ConsumerName { get; set; }
    public List<Brand> Brands { get; set; }
}

public class Brand
{
    public string BrandName { get; set; }
}

品牌部分进一步定义如下

public ActionResult<JObject> Post([FromBody] APIInputObject apiInputObject)

public class APIInputObject
{
    public string ApiKey { get; set; }
    public Brand Brand { get; set; }
    public string Query { get; set; }
    public string Locale { get; set; } = "SE";
    public string UseFormatter { get; set; }
}

public class Consumer
{
    public string ConsumerName { get; set; }
    public List<Brand> Brands { get; set; }
}

public class Brand
{
    public string BrandName { get; set; }
}

错误如下

{
    "errors": {
        "Brand": [
            "Error converting value \"xx\" to type 'Pim.Models.Brand'. Path 'Brand', line 3, position 17."
        ]
},

如何修复此错误？

您的原始JSON格式错误，应采用以下格式：

{
    "apiKey": "xxx",
    "Brand": {
        "BrandName": "xx"
    },
    "query": "showBrand"
}

额外帮助，对于您的消费者对象，您的json格式如下：

{
    "ConsumerName": "xxx",
    "Brands": [{
        "BrandName": "xx1"
    },
    {
        "BrandName": "xx2"
    }]
}
