第一步：先编写webapi接口：
接口介绍：
1、接口采用appkey和appsecret
2、访问的话，在报文头加上，appkey和sign。
1、sign由请求地址（例如：http://www.xxx.com/api/user/xx/,那么地址是/api/user/xx/）+appsecret+queryString或者报文体使用SHA1散列算法得出。
Filter代码:
1 string appKey = "fjdsakljg";
2 string appSecret = "dfhdjsklahfkdsbgkfdhtu";
3
4 public void OnAuthorization(AuthorizationFilterContext context)
5 {
6 string method = context.HttpContext.Request.Method.ToLower();
7 string path = context.HttpContext.Request.Path.Value;
8 string thSign = "";
9 StringValues appkeys;
10 StringValues signs;
11 if (!context.HttpContext.Request.Headers.TryGetValue("appKey", out appkeys))
12 {
13 context.Result = new JsonResult(new APIResult<int> { Code = 1, Message = "appkey不存在" });
14 return;
15 }
16 if (!context.HttpContext.Request.Headers.TryGetValue("sign", out signs))
17 {
18 context.Result = new JsonResult(new APIResult<int> { Code = 1, Message = "sign不存在" });
19 return;
20 }
21 string sign = signs.First();
22 string key = appkeys.First();
23 if (key != appKey)
24 {
25 context.Result = new JsonResult(new APIResult<int> { Code = 1, Message = "appkey错误" });
26 return;
27 }
28 if (method == "get" || method == "delete")
29 {
30 IQueryCollection reqUrls = context.HttpContext.Request.Query;
31 StringBuilder sb = new StringBuilder();
32 var querys = reqUrls.OrderBy(k => k.Key).Select(e => e.Key + "=" + e.Value);
33 string query = string.Join("&", querys);
34 thSign = CaclSHA(path + appSecret + query);
35 }
36 else
37 {
38 IQueryCollection reqUrls = context.HttpContext.Request.Query;
39 StringBuilder sb = new StringBuilder();
40 var querys = reqUrls.OrderBy(k => k.Key).Select(e => e.Key + "=" + e.Value);
41 string query = string.Join("&", querys);
42 //读取报文体
43 var requestBodyStream = new MemoryStream();
44 context.HttpContext.Request.Body.CopyTo(requestBodyStream);
45 requestBodyStream.Seek(0, SeekOrigin.Begin);
46 string body = new StreamReader(requestBodyStream, Encoding.UTF8).ReadToEnd();
47 requestBodyStream.Seek(0, SeekOrigin.Begin);
48 context.HttpContext.Request.Body = requestBodyStream;
49 thSign = CaclSHA(path+appSecret+body);
50 }
51 if (!sign.Equals(thSign,StringComparison.InvariantCultureIgnoreCase))
52 {
53 context.Result = new JsonResult(new APIResult<int> { Code = 1, Message = "sign错误" });
54 return;
55 }
56 }
View Code
2、编写SDK包：
3、剩下就是部署了，我暂且拿虚拟机来测试
在ubuntu 16.04装上nginx
然后修改nginx的配置：
然后启动。访问就行了：
