|
||||
@RequestMapping("/captcha")

<img src="/captcha" width="130px" height="48px" />
|
||||
```
|
||||
|
||||
### 3.1.快速使用
|
||||
1.在web.xml里面加入如下配置：
|
||||
> 不要忘了把`/captcha`路径排除登录拦截，比如shiro的拦截。
|
||||
|
||||
### 4.2.在servlet中使用
|

|
||||
|
||||
### 3.2.在SpringMVC中使用
|
||||
也可以使用controller的形式输出验证码，方法如下：
|
||||
```java
|
||||
@Controller
|
||||
public class MainController {
|
||||
|
||||
@RequestMapping("/images/captcha")

```
|
||||
前端代码：
|
||||

|
||||
<img src="/images/captcha" />
|
||||
```
|
||||
|
||||
### 3.3.判断验证码是否正确
|
||||

|
||||
if (!CaptchaUtil.ver(verCode, request)) {
|
||||
CaptchaUtil.clear(request); // 清除session中的验证码
|
||||
return JsonResult.error("验证码不正确");
|
||||
}
|
||||
}
|
||||

||||

```
|
||||
|
||||
### 3.5.不使用工具类
|
||||

||||

||||
```
|
||||
|
||||
## 5.自定义效果
|
||||
---
|
||||
|
||||
参考源代码中的SpecCaptcha和GifCaptcha继承Captcha即可。
|
||||
## 6.前后端分离项目的使用
|
||||
|
||||
 前后端分离项目建议不要存储在session中，存储在redis中，redis存储需要一个key，key一同返回给前端用于验证输入：
|
||||
```java
|
||||
@Controller
|
||||
public class CaptchaController {
|
||||
@Autowired
|
||||
private RedisUtil redisUtil;
|
||||
|
||||
@ResponseBody
|
||||
@RequestMapping("/captcha")
|
||||
public JsonResult captcha(HttpServletRequest request, HttpServletResponse response) throws Exception {
|
||||
SpecCaptcha specCaptcha = new SpecCaptcha(130, 48, 5);
|
||||
String verCode = specCaptcha.text().toLowerCase();
|
||||
String key = UUID.randomUUID().toString();
|
||||
// 存入redis并设置过期时间为30分钟
|
||||
redisUtil.setEx(key, verCode, 30, TimeUnit.MINUTES);
|
||||
// 将key和base64返回给前端
|
||||
return JsonResult.ok().put("key", key).put("image", specCaptcha.toBase64());
|
||||
}
|
||||
|
||||
@ResponseBody
|
||||
@PostMapping("/login")
|
||||
public JsonResult login(String username,String password,String verCode,String verKey){
|
||||
// 获取redis中的验证码
|
||||
String redisCode = redisUtil.get(verKey);
|
||||
// 判断验证码
|
||||
if (verCode==null || !redisCode.equals(verCode.trim().toLowerCase())) {
|
||||
return JsonResult.error("验证码不正确");
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
前端使用ajax获取验证码：
|
||||
```html
|
||||
<img id="verImg" width="130px" height="48px"/>
|
||||
|
||||
<script>
|
||||
var verKey;
|
||||
// 获取验证码
|
||||
$.get('/captcha', function(res) {
|
||||
verKey = res.key;
|
||||
$('#verImg').attr('src', res.image);
|
||||
},'json');
|
||||
|
||||
// 登录
|
||||
$.post('/login', {
|
||||
verKey: verKey,
|
||||
verCode: '8u6h',
|
||||
username: 'admin'，
|
||||
password: 'admin'
|
||||
}, function(res) {
|
||||
console.log(res);
|
||||
}, 'json');
|
||||
</script>
|
||||
```
|
||||
|
||||
