## 3.使用方法
|
|
|
|
|
### 4.1.在SpringMVC中使用
|
|
|
|
|
```java
|
|
|
|
|
@Controller
|
|
|
|
|
public class CaptchaController {
|
|
|
|
|
|
|
|
|
|
### 3.1.快速使用
|
|
|
|
|
1.在web.xml里面加入如下配置：
|
|
|
|
|
@RequestMapping("/captcha")
|
|
|
|
|
public void captcha(HttpServletRequest request, HttpServletResponse response) throws Exception {
|
|
|
|
|
CaptchaUtil.out(request, response);
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
|
|
前端html代码：
|
|
|
|
|
```html
|
|
|
|
|
<img src="/captcha" width="130px" height="48px" />
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
> 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
|
|
|
|
|
web.xml中配置servlet：
|
|
|
|
|
```xml
|
|
|
|
|
<web-app>
|
|
|
|
|
<!-- 图形验证码servlet -->

|
|
|
public class MainController {
|

|
|
|
public void captcha(HttpServletRequest request, HttpServletResponse response) throws Exception {
|
|
|

|
CaptchaUtil.out(request, response);

|
|
|
|
}

## 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" />
|
|
|
|
|
|
|
|
|
|
<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>
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
中文gif验证码：
|
|
|
|
|
> RedisUtil到这里获取[https://gitee.com/whvse/RedisUtil](https://gitee.com/whvse/RedisUtil)
|
|
|
|
|
|
|
|
|
|
```java
|
|
|
|
|
public class Test {
|
|
|
|
|
---
|
|
|
|
|
|
|
|
|
|
public static void main(String[] args) {
|
|
|
|
|
OutputStream outputStream = new FileOutputStream(new File("D:/a/aa.png"));
|
|
|
|
|
## 7.自定义效果
|
|
|
|
|
|
|
|
|
|
// 三个参数分别为宽、高、位数
|
|
|
|
|
ChineseGifCaptcha chineseGifCaptcha = new ChineseGifCaptcha(130, 48, 4);
|
|
|
|
|
 继承`Captcha`实现`out`方法，中文验证码可继承`ChineseCaptchaAbstract`，算术验证码可继承`ArithmeticCaptchaAbstract`。
|
|
|
|
|
|
|
|
|
|
// 设置字体
|
|
|
|
|
chineseGifCaptcha.setFont(new Font("楷体", Font.PLAIN, 28)); // 有默认字体，可以不用设置
|
|
|
|
|
---
|
|
|
|
|
|
|
|
|
|
// 生成的验证码
|
|
|
|
|
String code = chineseGifCaptcha.text();
|
|
|
|
|
