+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# ocr_api_server
+使用ddddocr的最简api搭建项目，支持docker
+
+**建议python版本3.7-3.9 64位**
+
+再有不好好看文档的我就不管了啊！！！
+
+# 运行方式
+
+## 最简单运行方式
+
+```shell
+# 安装依赖
+pip install -r requirements.txt -i https://pypi.douban.com/simple
+
+# 运行  可选参数如下
+# --port 9898 指定端口,默认为9898
+# --ocr 开启ocr模块 默认开启
+# --old 只有ocr模块开启的情况下生效 默认不开启
+# --det 开启目标检测模式
+
+# 最简单运行方式，只开启ocr模块并以新模型计算
+python ocr_server.py --port 9898 --ocr
+
+# 开启ocr模块并使用旧模型计算
+python ocr_server.py --port 9898 --ocr --old
+
+# 只开启目标检测模块
+python ocr_server.py --port 9898  --det
+
+# 同时开启ocr模块以及目标检测模块
+python ocr_server.py --port 9898 --ocr --det
+
+# 同时开启ocr模块并使用旧模型计算以及目标检测模块
+python ocr_server.py --port 9898 --ocr --old --det
+
+```
+
+## docker运行方式(目测只能在Linux下部署)
+
+```shell
+git clone https://github.com/sml2h3/ocr_api_server.git
+# docker怎么安装？百度吧
+
+cd ocr_api_server
+
+# 修改entrypoint.sh中的参数，具体参数往上翻，默认9898端口，同时开启ocr模块以及目标检测模块
+
+# 编译镜像
+docker build -t ocr_server:v1 .
+
+# 运行镜像
+docker run -p 9898:9898 -d ocr_server:v1
+
+```
+
+# 接口
+
+**具体请看test_api.py文件**
+
+```python
+# 1、测试是否启动成功，可以通过直接GET访问http://{host}:{port}/ping来测试，如果返回pong则启动成功
+
+# 2、OCR/目标检测请求接口格式：
+
+# http://{host}:{port}/{opt}/{img_type}/{ret_type}
+# opt：操作类型 ocr=OCR det=目标检测 slide=滑块（match和compare两种算法，默认为compare)
+# img_type: 数据类型 file=文件上传方式 b64=base64(imgbyte)方式 默认为file方式
+# ret_type: 返回类型 json=返回json（识别出错会在msg里返回错误信息） text=返回文本格式（识别出错时回直接返回空文本）
+
+# 例子：
+
+# OCR请求
+# resp = requests.post("http://{host}:{port}/ocr/file", files={'image': image_bytes})
+# resp = requests.post("http://{host}:{port}/ocr/b64/text", data=base64.b64encode(file).decode())
+
+# 目标检测请求
+# resp = requests.post("http://{host}:{port}/det/file", files={'image': image_bytes})
+# resp = requests.post("http://{host}:{port}/det/b64/json", data=base64.b64encode(file).decode())
+
+# 滑块识别请求
+# resp = requests.post("http://{host}:{port}/slide/match/file", files={'target_img': target_bytes, 'bg_img': bg_bytes})
+# jsonstr = json.dumps({'target_img': target_b64str, 'bg_img': bg_b64str})
+# resp = requests.post("http://{host}:{port}/slide/compare/b64", files=base64.b64encode(jsonstr.encode()).decode())
+```
