在ASP.NET Core 7 Web API中,Angular表单控件的日期序列化可以通过以下步骤解决:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';
import { AppComponent } from './app.component';
import { MyDatePipe } from './my-date.pipe';
@NgModule({
declarations: [AppComponent, MyDatePipe],
imports: [BrowserModule, FormsModule],
providers: [],
bootstrap: [AppComponent],
})
export class AppModule {}
import { Pipe, PipeTransform } from '@angular/core';
import { DatePipe } from '@angular/common';
@Pipe({
name: 'myDate',
})
export class MyDatePipe implements PipeTransform {
transform(value: any, format: string = 'yyyy-MM-dd'): any {
const datePipe = new DatePipe('en-US');
return datePipe.transform(value, format);
}
}
CustomDateTimeModelBinder
的类,并继承自IModelBinder
接口。using System;
using System.Globalization;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc.ModelBinding;
public class CustomDateTimeModelBinder : IModelBinder
{
public Task BindModelAsync(ModelBindingContext bindingContext)
{
var modelName = bindingContext.ModelName;
var valueProviderResult = bindingContext.ValueProvider.GetValue(modelName);
if (valueProviderResult == ValueProviderResult.None)
{
return Task.CompletedTask;
}
bindingContext.ModelState.SetModelValue(modelName, valueProviderResult);
var value = valueProviderResult.FirstValue;
if (string.IsNullOrEmpty(value))
{
return Task.CompletedTask;
}
if (!DateTime.TryParseExact(value, "yyyy-MM-dd", CultureInfo.InvariantCulture, DateTimeStyles.None, out var result))
{
bindingContext.ModelState.TryAddModelError(bindingContext.ModelName, "Invalid date format");
return Task.CompletedTask;
}
bindingContext.Result = ModelBindingResult.Success(result);
return Task.CompletedTask;
}
}
[ModelBinder(typeof(CustomDateTimeModelBinder))]
特性将自定义的ModelBinder应用到日期参数上。[HttpPost]
public IActionResult Create([ModelBinder(typeof(CustomDateTimeModelBinder))] DateTime date)
{
// 使用反序列化后的日期进行操作
return Ok();
}
注意:以上代码示例仅为参考,实际应用中可能需要根据具体需求进行调整和优化。
