通用 HTTP 签名组件的另类实现方式

辛巴海

1、初衷

开发中经常需要做一些接口的签名生成和校验工作，最开始的时候都是每个接口去按照约定单独实现，久而久之就变的非常难维护，因此就琢磨怎么能够写了一个比较通用的签名生成工具。

2、思路

采用链式调用的方式，使得签名的步骤可以动态拼凑组合。

3、直接看效果

1. //设置数据源
2. var signSource = new Dictionary<string, string>()
3. {
4. { "param1", "1" },
5. { "param3", "3+" },
6. { "param2", "2" }
7. };
8. var signer = new HttpSigner();
9. signer.SetSignData(signSource);
11. //设置数据源并配置规则
12. signer.SetSignData(signSource, setting =>
13. {
14. //按参数名排序
15. //result --> param1 param2 param3
16. setting.IsOrderByWithKey = false;
18. //是否对签名数据的参数值进行UrlEncode
19. setting.IsDoUrlEncodeForSourceValue = false;
21. //签名主体是否包含参数名
22. setting.IsSignTextContainKey = true;
23. //签名主体中参数和参数值的连接符（需要启用IsSignTextContainKey）
24. setting.SignTextKeyValueSeparator = "=";
25. //签名主体中不同参数项的连接符
26. setting.SignTextItemSeparator = "&";
27. //以上都开启后 --> param1=1&param2=2&param3=3
29. //编码
30. setting.DefaultEncoding = Encoding.UTF8;
31. });
33. //签名主体设置前缀
34. signer.SetSignData(signSource).SetSignTextPrefix("TestPrefix");
36. //签名主体设置后缀
37. signer.SetSignData(signSource).SetSignTextSuffix("TestSuffix");
39. //签名主体进行Base64
40. signer.SetSignData(signSource).SetSignTextBase64();
42. //签名主体进行MD5,(方法参数为签名结果是否转小写)
43. signer.SetSignData(signSource).SetSignTextMD5(bool isToLower = true);
45. //签名主体进行SHA1,(方法参数为签名结果是否转小写)
46. signer.SetSignData(signSource).SetSignTextSHA1(bool isToLower = true);
48. //获取签名结果
49. string signString = signer.SetSignData(signSource).GetSignResult();
51. //组合调用
52. string signString = signer.SetSignData(signSource).SetSignTextBase64().SetSignTextMD5().SetSignTextSHA1();

4、代码实现

HttpSignItem类

用于保存签名的参数集合。

1. namespace JiuLing.CommonLibs.Security.HttpSign
2. {
3. internal class HttpSignItem
4. {
5. public string Key { get; set; }
6. public string Value { get; set; }
8. public HttpSignItem(string key, string value)
9. {
10. Key = key;
11. Value = value;
12. }
13. }
14. }

复制代码

HttpSignSetting类

用于签名的基本配置。

1. using System.Text;
3. namespace JiuLing.CommonLibs.Security.HttpSign
4. {
5. /// <summary>
6. /// 签名配置
7. /// </summary>
8. public class HttpSignSetting
9. {
10. /// <summary>
11. /// 是否按参数名进行排序
12. /// </summary>
13. public bool IsOrderByWithKey { get; set; } = false;
15. /// <summary>
16. /// 是否对签名数据的参数值进行UrlEncode
17. /// </summary>
18. public bool IsDoUrlEncodeForSourceValue { get; set; } = false;
20. /// <summary>
21. /// 签名主体是否包含参数名
22. /// </summary>
23. public bool IsSignTextContainKey { get; set; } = true;
25. /// <summary>
26. /// 签名主体中参数和参数值的连接符（需要启用IsSignTextContainKey）
27. /// </summary>
28. public string SignTextKeyValueSeparator { get; set; } = "=";
30. /// <summary>
31. /// 签名主体中不同参数项的连接符
32. /// </summary>
33. public string SignTextItemSeparator { get; set; } = "&";
35. /// <summary>
36. /// 编码
37. /// </summary>
38. public Encoding DefaultEncoding { get; set; } = Encoding.UTF8;
39. }
40. }
