## 快速启动服务
以下步骤以检测+识别2阶段串联服务为例，如果只需要检测服务或识别服务，替换相应文件路径即可。
### 1. 安装paddlehub
```pip3 install paddlehub --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple```
### 1. 准备环境
```shell
# 安装paddlehub
pip3 install paddlehub --upgrade -i https://pypi.tuna.tsinghua.edu.cn/simple
# 设置环境变量
export PYTHONPATH=.
```
### 2. 安装服务模块
PaddleOCR提供3种服务模块，根据需要安装所需模块。如：

## 发送预测请求
配置好服务端，以下数行代码即可实现发送预测请求，获取预测结果:
配置好服务端，可使用以下命令发送预测请求，获取预测结果:
```python
import requests
import json
import cv2
import base64
def cv2_to_base64(image):
return base64.b64encode(image).decode('utf8')
# 发送HTTP请求
data = {'images':[cv2_to_base64(open("./doc/imgs/11.jpg", 'rb').read())]}
headers = {"Content-type": "application/json"}
# url = "http://127.0.0.1:8866/predict/ocr_det"
# url = "http://127.0.0.1:8866/predict/ocr_rec"
url = "http://127.0.0.1:8866/predict/ocr_system"
r = requests.post(url=url, headers=headers, data=json.dumps(data))
# 打印预测结果
print(r.json()["results"])
```
```python tools/test_hubserving.py server_url image_path```
你可能需要根据实际情况修改`url`字符串中的端口号和服务模块名称。
需要给脚本传递2个参数：
- **server_url**：服务地址，格式为
`http://[ip_address]:[port]/predict/[module_name]`
例如，如果使用配置文件启动检测、识别、检测+识别2阶段服务，那么发送请求的url将分别是：
`http://127.0.0.1:8866/predict/ocr_det`
`http://127.0.0.1:8867/predict/ocr_rec`
`http://127.0.0.1:8868/predict/ocr_system`
- **image_path**：测试图像路径，可以是单张图片路径，也可以是图像集合目录路径
上面所示代码都已写入测试脚本，可直接运行命令：```python tools/test_hubserving.py```
访问示例：
```python tools/test_hubserving.py http://127.0.0.1:8868/predict/ocr_system ./doc/imgs/```
## 自定义修改服务模块
如果需要修改服务逻辑，你一般需要操作以下步骤（以修改`ocr_system`为例）：
