shiro 为什么跑出 incorrectcredentialsexception

这是shiro常见的问题。

IncorrectCredentialsException当输入密码错误就会出现这种异常，如下：org.apache.shiro.authc.IncorrectCredentialsException: Submitted credentials for token [org.apache.shiro.authc.UsernamePasswordToken - zhangsan, rememberMe=false] did not match the expected credentials.

如何正确使用 Django Forms

1. Django Forms的强大之处 有些django项目并不直接呈现HTML， 二是以API框架的形式存在， 但你可能没有想到， 在这些API形式的django项目中也用到了django forms. django forms不仅仅是用来呈现HTML的， 他们最强的地方应该是他们的验证能力. 下面我们就介绍几种和Django forms结合使用的模式：2. 模式一： ModelForm和默认验证 最简单的使用模式便是ModelForm和model中定义的默认验证方式的组合： # myapp/views.py from django.views.generic import CreateView, UpdateView from braces.views import LoginRequiredMixin from .models import Article class ArticleCreateView(LoginRequiredMixin, CreateView): model = Article fields = ("title", "slug", "review_num") class ArticleUpdateView(LoginRequiredMixin, UpdateView): model = Article fields = ("title", "slug", "review_num") 正如以上代码中看到的一样：ArticleCreateView和ArticleUpdateView中设置model为Article 两个view都基于Article model自动生成了ModelForm 这些ModelForm的验证， 是基于Article model中定义的field转换而来的3. 模式二， 在ModelForm中修改验证 在上面的例子中， 如果我们希望每篇article title的开头都是＂new＂， 那么应该怎么做呢？ 首先我们需要建立自定义的验证（validator）: # utils/validator.py from django.core.exceptions import ValidationError def validate_begins(value): if not value.startswith(u"new"): raise ValidationError(u"Must start with new") 可见， 在django中的验证程序就是不符合条件便抛出ValidationError的function， 为了方便重复使用， 我们将它们放在django app utils的validators.py中.接下来， 我们可以在model中加入这些validator， 但为了今后的方便修改和维护， 我们更倾向于加入到ModelForm中： # myapp/forms.py from django import forms from utils.validators import validate_begin from .models import Article class ArticleForm(forms.ModelForm): dev __init__(self, *args, **kwargs): super(ArticleForm, self).__init__(8args, **kwargs) self.fields[＂title＂].validators.append(validate_begin) class Meta: model = Article Django的edit views(UpdateView和CreateView等)的默认行为是根据view中model属性， 自动创建ModelForm. 因此， 我们需要调用我们自己的Modelform来覆盖自动创建的： # myapp/views.py from django.views.generic import CreateView, UpdateView from braces.views import LoginRequiredMixin from .models import Article from .forms import ArticleForm class ArticleCreateView(LoginRequiredMixin, CreateView): model = Article fields = ("title", "slug", "review_num") form_class = ArticleForm class ArticleUpdateView(LoginRequiredMixin, UpdateView): model = Article fields = ("title", "slug", "review_num") form_class = ArticleForm4. 模式三， 使用form的clean（)和clean_（)方法 如果我们希望验证form中的多个field， 或者验证涉及到已经存在之后的数据， 那么我们就需要用到form的clean（)和clean_&（)方法了. 以下代码检查密码长度是否大于7位， 并且password是否和password2相同： # myapp/forms.py from django import forms class MyUserForm(forms.Form): username = forms.CharField() password = forms.CharField() password2 = forms.CharField() def clean_password(self): password = self.cleaned_data["password"] if len(password) raise forms.ValidationError(＂password insecure＂) return password def clean(): cleaned_data = super(MyUserForm, self).clean() password = cleaned_data.get("password", "") password2 = cleaned_data.get("password2", "") if password != password2: raise forms.ValidationError(＂passwords not match＂) return cleaned_data 其中需要注意的是， clean（)和clean_&（)的最后必须返回验证完毕或修改后的值.5. 模式四， 自定义ModelForm中的field 我们会经常遇到在form中需要修改默认的验证， 比如一个model中有许多非必填项， 但为了信息完整， 你希望这些field在填写时是必填的： # myapp/models.py from django.db import models class MyUser(models.Model): username = models.CharField(max_length=100) password = models.CharField(max_length=100) address = models.TextField(blank=True) phone = models.CharField(max_length=100, blank=True) 为了达到以上要求， 你可能会通过直接增加field改写ModelForm： # 请不要这么做 # myapp/forms.py from django import forms from .models import MyUser class MyUserForm(forms.ModelForm)： # 请不要这么做 address = forms.CharField(required=True) # 请不要这么做 phone = forms.CharField(required=True) class Meta: model = MyUser 请不要这么做， 因为这违反＂不重复＂的原则， 而且经过多次的拷贝粘贴， 代码会变得复杂难维护. 正确的方式应当是利用__init__(): # myapp/forms.py from django import forms from .models import MyUser class MyUserForm(forms.ModelForm): def __init__(self, *args, **kwarg): ...

使用aspnet.identity 身份验证的框架中,怎么对现有用户进行删除

首先让我先更新 API 项目 我先 API 项目进行必要修改修改完再切换 Web 项目客户端进行更新 第1步：我需要数据库 能做任何操作前我需要先创建数据库本例使用 SQL Server Express没安装载 SQL Server Express安装完创建名 CallingWebApiFromMvc 数据库第步要做 Api 项目需要数据库连接字符串否则我寸步难行面段代码插入 Api 项目Web.config 文件：认证（Identity）框架自创建我管理用户所需要员关系表现需要担提前创建 第2步：添加相关Nuget包 接我添加用于OWINWindows认证Nuget包打包管理控制台切换Api项目缺省项目输入命令：Install-Package Microsoft.AspNet.WebApi.Owin Install-Package Microsoft.Owin.Host.SystemWeb Install-Package Microsoft.AspNet.Identity.EntityFramework Install-Package Microsoft.AspNet.Identity.Owin 使用些包我应用启OWIN服务器通EntityFramework我用户保存SQL Server 第3步：添加管理用户Identity类 我使用基于Windows认证机制Entity框架管理数据库相关业务首先我需要添加些用于处理类Api项目添加Identity目录作我要添加类命名空间添加类：public class ApplicationUser : IdentityUser { } public class ApplicationDbContext : IdentityDbContext { public ApplicationDbContext() : base(＂ApiFromMvcConnection＂) {} public static ApplicationDbContext Create() { return new ApplicationDbContext（)； } } 注意我传给基类构造函数参数ApiFromMvcConnection要Web.config连接字符串name相匹配 public class ApplicationUserManager : UserManager { public ApplicationUserManager(IUserStore store) : base(store) { } public static ApplicationUserManager Create(IdentityFactoryOptions options, IOwinContext context) { var manager = new ApplicationUserManager(new UserStore (context.Get ()));// Configure validation logic for usernames manager.UserValidator = new UserValidator (manager) { AllowOnlyAlphanumericUserNames = false,RequireUniqueEmail = true };// Configure validation logic for passwords manager.PasswordValidator = new PasswordValidator { RequiredLength = 6,RequireNonLetterOrDigit = true,RequireDigit = true,RequireLowercase = true,RequireUppercase = true,}; var dataProtectionProvider = options.DataProtectionProvider; if (dataProtectionProvider != null) { manager.UserTokenProvider = new DataProtectorTokenProvider (dataProtectionProvider.Create(＂ASP.NET Identity＂)); } return manager； } } 第4步：添加OWIN启类 让我应用程序作OWIN服务器运行我需要应用程序启初始化我通启类做点我装点类 OwinStartup属性应用程序启触发意味着我摆脱Global.asax移 Application_Start代码转换我新启类 using Microsoft.Owin; [assembly: OwinStartup(typeof(Levelnis.Learning.CallingWebApiFromMvc.Api.Startup))] namespace Levelnis.Learning.CallingWebApiFromMvc.Api { using System; using System.Web.Http; using Identity; using Microsoft.Owin.Security.OAuth; using Owin; using Providers; public class Startup { public void Configuration(IAppBuilder app) { GlobalConfiguration.Configure(WebApiConfig.Register); app.CreatePerOwinContext(ApplicationDbContext.Create); app.CreatePerOwinContext (ApplicationUserManager.Create); var oAuthOptions = new OAuthAuthorizationServerOptions { TokenEndpointPath = new PathString(＂/api/token＂),Provider = new ApplicationOAuthProvider(),AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),AllowInsecureHttp = true }; // Enable the application to use bearer tokens to authenticate users app.UseOAuthBearerTokens(oAuthOptions)； } } } 应用程序启我建立自服务器我配置令牌端点并设置自自定义提供商我用我用户进行身份验证我例我使用ApplicationOAuthProvider类让我看看现：第5步：添加OAuth提供商 public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider { public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context) { context.Validated(); return Task.FromResult (null); } public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context) { var userManager = context.OwinContext.GetUserManager (); var user = await userManager.FindAsync(context.UserName, context.Password); if (user == null) { context.SetError(＂invalid_grant＂, ＂The user name or password is incorrect.＂); return; } var oAuthIdentity = await user.GenerateUserIdentityAsync(userManager, OAuthDefaults.AuthenticationType); var cookiesIdentity = await user.GenerateUserIdentityAsync(userManager, CookieAuthenticationDefaults.AuthenticationType); var properties = CreateProperties(user.UserName); var ticket = new AuthenticationTicket(oAuthIdentity, properties); context.Validated(ticket); context.Request.Context.Authentication....
