ASP.NET WebAPI2第005天_API驗證

不管是面對User的WebSite或者網站程式端對端的API

都需要對傳入資料進行驗證

新增一個Customer的DTO Model 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

using System; using System.Collections.Generic; using System.ComponentModel.DataAnnotations; using System.Linq; using System.Web; namespace MyWebAPI2_Test0.Models { public class Customer { public int Id { get; set; } [Required, StringLength(15)] public string Name { get; set; } [RegularExpression(@"^([\w\.\-]+)@([\w\-]+)((\.(\w){2,})+)$", ErrorMessage = "Email in not valid")] public string Email { get; set; } [RegularExpression("^[0-9]+$", ErrorMessage = "Invalid Phone Number")] public string Phone { get; set; } } }

一些正則表達式驗證補充(這邊用簡單還沒這麼嚴謹查檢)

Email 格式驗證正則表達式
^([\w\.\-]+)@([\w\-]+)((\.(\w){2,3})+)$
^([\w\.\-]+)@([\w\-]+)((\.(\w){2,})+)$

	^			比對輸入列的啟始位置
	$			比對輸入列的結束位置
(pattern)		匹配pattern並獲取這一匹配
[字元集合]		比對中括弧內的任一個字元
[]+				一或多個
\w				數字、字母、底線	[a-zA-Z0-9_]
\.\-			「-」或是「.」
				比方
				@tintint.co
				@email.coursera.org
				@acer-mail.com
				@hahow.in
				@reply.agoda-emails.com
				@taaze-fun.com
				@nedm.ubot.com.tw
				@mail.member-mail.ithome.com.tw
{2,3}			最少匹配到2次且最多匹配3次(或以上),比方
				.com,
				.com.tw,
				.dks.com.tw,
				.org,
				.cc,
				.jp,				
				.co,				
{2,}			最少匹配到2次以上,比方.info
				.foodpanda.com.tw,
				.netflix.com,
				.post.gov.tw,
				.buy123.com.tw,
				
電話號碼 正則表達式
^[0-9]*$		至少可0個數字，最多不限制數字字元數		
^[0-9]+$		至少一個數字，最多不限制數字字元數

跟Customers API控制器

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51

using MyWebAPI2_Test0.Models; using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Net.Http; using System.Web.Http; namespace MyWebAPI2_Test0.Controllers { public class CustomersController : ApiController { static List<Customer> customers = new List<Customer>() { new Customer(){Id=1,Name = "Tom Cruise",Email = "tomcruise@gmail.com",Phone = "3322"}, new Customer(){Id=1,Name = "Robert Downy Jr",Email = "robert@gmail.com",Phone = "326"}, new Customer(){Id=1,Name = "Chris patt",Email = "cpatt@hotmail.com",Phone = "659"}, }; // GET: api/Customers public IEnumerable<Customer> Get() { return customers; } // GET: api/Customers/5 public string Get(int id) { return "value"; } // POST: api/Customers public IHttpActionResult Post([FromBody] Customer customer) { if (ModelState.IsValid) { customers.Add(customer); return Ok(); } return BadRequest(ModelState); } // PUT: api/Customers/5 public void Put(int id, [FromBody] string value) { } // DELETE: api/Customers/5 public void Delete(int id) { } } }
