Web API 是否从角度获取 NULL 值作为"NULL"？

Question

我有一个webAPI文件&角度文件，空值从该角度文件传递到web API。在传递空值的同时，它反映为"0"；NULL"；。我的API控制器TS文件如下

getOfficeOrganizationalRoles(OfficeSelected,gbobranchname): ng.IHttpPromise<SelectItem[]> {
//return this.http.get(this.apiEndpoints.baseUrl + this.apiEndpoints.getOfficeOrganizationalRoles + "?officeIds=" + OfficeSelected + "&gbobranch=" + gbobranchname);
return this.http.get(this.apiEndpoints.baseUrl + this.apiEndpoints.getOfficeOrganizationalRoles + "?officeIds=" + OfficeSelected);
};

我怎样才能用"quot；已删除。我需要OfficeIds&gbobbranch。

Answer 1

试着这样做，这样如果参数为空，就不必传递参数

getOfficeOrganizationalRoles(OfficeSelected, gbobranchname): ng.IHttpPromise<SelectItem[]> {
const params: any = {};
if (OfficeSelected) {
params.officeIds = OfficeSelected;
}
if (gbobranchname) {
params.gbobranch = gbobranchname;
}
return this.httpClient.get(this.apiEndpoints.baseUrl + this.apiEndpoints.getOfficeOrganizationalRoles, { params });
};
