生成验证码 图片 ～（BytesIO，image file， base64）， 文字
# install
```shell
pip install simpel_captcha
```
# use
## 文字验证码
```python
from simpel_captcha import captcha
code = captcha()
```
## 图片验证码（本地保存）
```python
from simpel_captcha import img_captcha
img, code = img_captcha()
print(f'图片对象: {image}')
print(f'验证码: {text}')
```
output:
```shell
图片对象:
验证码: TjXP
```
## 图片验证码（BytesIO）- 可使用`Web框架`直接通过流的形式返回
``` python
from simpel_captcha import img_captcha
img, code = img_captcha(byte_stream=True)
```
### fastapi example
```python
from fastapi import FastAPI
from fastapi.responses import StreamingResponse
from simpel_captcha import img_captcha
app = FastAPI()
@app.get("/captcha", summary='图片验证码')
def image_captcha():
image, text = img_captcha(byte_stream=True)
# todo 将验证码缓存到Redis中
return StreamingResponse(content=image, media_type='image/jpeg')
```
## base64字符串（推荐使用）
```python
from simpel_captcha import b64_captcha
obj, code = b64_captcha()
print(f'base64图片: {image}')
print(f'验证码: {text}')
```
output:
```shell
# 直接将base64字符串 复制到浏览器
