c#关于 做接口开发时，遇到的Form表单提交数据

遇到接口开发时，对接客户要求发送请求数据为form表单提交，以下是经过大佬们写过类似整理出来适合我自己用的一套

 public class FormItemModel {  /// <summary>  ///主键  /// </summary>  public string Key { set; get; }  /// <summary>  /// 值  /// </summary>  public string Value { set; get; }  /// <summary>  /// 值  /// </summary>  public long Values { get; set; } }

 1 private void btn_Click(object sender, EventArgs e) 2 { 4 var url = "*******************************"; 5 long _ts = ConvertDataTimeToLong(DateTime.Now); 6 string _appSecret = "*************"; 7 string _appId = "****************"; 8 string _tokens = "";//加密 9 string _Num = "123";10 string _Code = "111";11 string _idNo = "1111";12 var formDatas = new List<FormItemModel>();13 14 formDatas.Add(new FormItemModel()15 {16 Key = "appId",17 Value = _appId18 });19 formDatas.Add(new FormItemModel()20 {21 Key = "ts",22 Values = _ts23 });24 formDatas.Add(new FormItemModel()25 {26 Key = "tokens",27 Value = _tokens28 });29 formDatas.Add(new FormItemModel()30 {31 Key = "Num",32 Value = _Num33 });34 formDatas.Add(new FormItemModel()35 {36 Key = "Code",37 Value = _Code38 });39 formDatas.Add(new FormItemModel()40 {41 Key = "idNo",42 Value = _idNo43 });44 //提交表单45 var result = HTExamDocking.PostForm(url, formDatas);46 if (result != null)47 {48 //MessageBox.Show("成功");49 }50 }
