通过这段代码,我试图将一个 Json 数组发布到我的 Web 核心 API 中的一个方法。但是数组到达时为空。
importProperties = function (url, callback, data) {
var properties = JSON.stringify(data);
$.ajax({
url: url,
type: "POST",
contentType: "application/json",
dataType: "json",
data: { "": properties }
})
.done(callback)
.fail(errorMessage);
}
一旦数据被 JSON.stringified,它看起来像;
[{"UPRN":"12345","StreetName":"COMPORT GREEN","AddressLine2":"NEW ADDINGTON","AddressLine3":"Croydon","AddressLine4":"Surrey","Postcode":"CR0 0BY","Latitude":null,"Longitude":null,"BlockUPRN":"B12345","PropertyNo":"1","BlockName":"Block Court","Comments":null,"PropertyTypeId":6,"NumberOfBathrooms":1,"NumberOfBedrooms":2,"NumberOfKitchens":1,"PropertyContractId":0,"PropertyType":null},
{"UPRN":"67890","StreetName":"COMPORT GREEN","AddressLine2":"NEW ADDINGTON","AddressLine3":"Croydon","AddressLine4":"Surrey","Postcode":"CR0 0BY","Latitude":null,"Longitude":null,"BlockUPRN":"B67890","PropertyNo":"2","BlockName":"Block Court","Comments":null,"PropertyTypeId":6,"NumberOfBathrooms":null,"NumberOfBedrooms":null,"NumberOfKitchens":null,"PropertyContractId":0,"PropertyType":null}]
我的网络核心 API 上的方法签名是;
[HttpPost("{contractId}/import")]
public async Task<IActionResult> Import(int contractId, [FromBody] IEnumerable<PropertyAndContractDto> properties)
{
this.NLogger.Info($"api/property/contractId = {contractId}/saveproperties".ToPrefix());
if (properties == null)
{
return BadRequest();
}
...
}
DTO 是
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,它起作用了;
那么为什么 properties 参数为 null?
最佳答案
尝试将 ajax 调用的 processData
属性设置为 false,如下所示:
$.ajax({
url: url,
type: "POST",
contentType: "application/json",
dataType: "json",
data: { "": properties },
processData: false
})
根据docs :
By default, data passed in to the data option as an object (technically, anything other than a string) will be processed and transformed into a query string, fitting to the default content-type "application/x-www-form-urlencoded". If you want to send a DOMDocument, or other non-processed data, set this option to false.
或者,只需将 data
属性设置为字符串化的 json:
$.ajax({
url: url,
type: "POST",
contentType: "application/json",
dataType: "json",
data: properties
})
