HTTP Digest authentication 疑问
http://blog.csdn.net/gl1987807/article/details/6090811

看了此文章,有些小疑问请教一下.

在PHP中怎样生成这些摘要认证信息中的参数值呢?
username = '用户名'
realm = '领域'
nonce = '现时'
uri = '客户端想要访问的URI'
qoq = '客户端选择的保护方式'
nc = ''
cnonce = ''
response = ''

等号后台有说明的表示我己经知道的.最后的三个参数值是怎么来的.文档中有说明,只是我不理解它们的意思.
nc,cnonce值是随机产生的还是由什么算法产生的?
response是不是对密码进行md5加密产生的?

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
