使用以下代码,我尝试将Json数组发布到Web Core API中的方法。然而,数组以null形式到达。
一旦数据被JSON.stringify处理,它的形式如下:
DTO是数据传输对象
当我在 Postman 中运行时,它可以正常工作;
那么为什么 properties 参数会变成 null 呢?
importProperties = function (url, callback, data) {
var properties = JSON.stringify(data);
$.ajax({
url: url,
type: "POST",
contentType: "application/json",
dataType: "json",
data: { "": properties }
})
.done(callback)
.fail(errorMessage);
}
一旦数据被JSON.stringify处理,它的形式如下:
[{"UPRN":"12345","StreetName":"COMPORT GREEN","AddressLine2":"NEW ADDINGTON","AddressLine3":"Croydon","AddressLine4":"Surrey","Postcode":"CR0 0BY","Latitude":null,"Longitude":null,"BlockUPRN":"B12345","PropertyNo":"1","BlockName":"Block Court","Comments":null,"PropertyTypeId":6,"NumberOfBathrooms":1,"NumberOfBedrooms":2,"NumberOfKitchens":1,"PropertyContractId":0,"PropertyType":null},
{"UPRN":"67890","StreetName":"COMPORT GREEN","AddressLine2":"NEW ADDINGTON","AddressLine3":"Croydon","AddressLine4":"Surrey","Postcode":"CR0 0BY","Latitude":null,"Longitude":null,"BlockUPRN":"B67890","PropertyNo":"2","BlockName":"Block Court","Comments":null,"PropertyTypeId":6,"NumberOfBathrooms":null,"NumberOfBedrooms":null,"NumberOfKitchens":null,"PropertyContractId":0,"PropertyType":null}]
我的Web核心API的方法签名是:
[HttpPost("{contractId}/import")]
public async Task<IActionResult> Import(int contractId, [FromBody] IEnumerable<PropertyAndContractDto> properties)
{
this.NLogger.Info($"api/property/contractId = {contractId}/saveproperties".ToPrefix());
if (properties == null)
{
return BadRequest();
}
...
}
DTO是数据传输对象
public class PropertyAndContractDto
{
public string UPRN { get; set; }
public string StreetName { get; set; }
public string AddressLine2 { get; set; }
public string AddressLine3 { get; set; }
public string AddressLine4 { get; set; }
public string Postcode { get; set; }
public string Latitude { get; set; }
public string Longitude { get; set; }
public string BlockUPRN { get; set; }
public string PropertyNo { get; set; }
public string BlockName { get; set; }
public string Comments { get; set; }
public int? PropertyTypeId { get; set; }
public int? NumberOfBathrooms { get; set; }
public int? NumberOfBedrooms { get; set; }
public int? NumberOfKitchens { get; set; }
public int PropertyContractId { get; set; }
public string PropertyType { get; set; }
}
}
当我在 Postman 中运行时,它可以正常工作;

PropertyAndContractDto
。请发布 DTO 类。类属性与字符串中的属性相同吗?首先,您能将此字符串解析为 DTO 数组吗? - Panagiotis Kanavosdata: { "": properties }
更改为data: { "properties": properties }
吗? - Siva Gopal
