【问题描述】:
我想采用从这个 Angular 打字稿前端代码构建的端点
getPartNumbersFromManufacture(manufactureNameId : Number)
{
let parameter = new HttpParams().set("FKManufactureNameId", manufactureNameId.toString())
return this.http.get<ManufacturePartNumber[]>(this.manufactureUrl + '/PartNumber', {params: parameter}).pipe(
tap(data => console.log('All: ' + JSON.stringify(data))),
catchError(this.handleError)
);
}
这会产生如下所示的请求:
Request URL: https://localhost:5001/api/Manufacture/PartNumber?FKManufactureNameId=14703
Request Method: GET
Status Code: 200 OK
Remote Address: [::1]:5001
Referrer Policy: no-referrer-when-downgrade
.netcore C# 代码如下所示,端点被命中,但制造名称 ID 始终为 =0,如果我尝试将其更改为字符串,则为空。
[Route("api/Manufacture")]
public class ManufactureController : ControllerBase
{ ...
[HttpGet("PartNumber/{FKManufactureNameId=manufactureNameID}")]
public IEnumerable<Views.ManufacturePartNumber> PartNumbers(int manufactureNameID) //pass the manufacture id from the frontend and get the part numbers associated with this manufacturer
{
TrackingContext context = new TrackingContext();
IEnumerable<ManufacturePartNumber> manufacturePartNumbers = context.ManufacturePartNumber.Where(n => n.FkManufactureNameId == manufactureNameID);
List<Views.ManufacturePartNumber> manufacturePartNumberView = new List<Views.ManufacturePartNumber>();
for (int i = 0; i < manufacturePartNumbers.Count(); i++)
{
manufacturePartNumberView.Add(new Views.ManufacturePartNumber(manufacturePartNumbers.ElementAt(i)));
}
return manufacturePartNumberView;
}
...}
我做错了什么,我希望我的 C# 代码处理这个具有等号的查询参数,因为这似乎是“HttPClient”类在传递“HttpParams”对象时构建查询参数的标准方式。我知道如何处理 no '=' 但我猜 '=' 是新的标准/最佳实践?
