From 82db8c5ac4d468807eb57cffbaec64d3176379f3 Mon Sep 17 00:00:00 2001 From: ModerRAS Date: Fri, 14 Nov 2025 10:09:03 +0000 Subject: [PATCH 1/7] feat: split OCR functionality into independent project - Created TelegramSearchBot.OCR as standalone OCR service - Implemented Redis-based communication between main bot and OCR service - Added Docker support for OCR service deployment - Updated PaddleOCRService to use RPC communication with standalone service - Added comprehensive documentation and configuration files - Maintained backward compatibility with existing OCR functionality The OCR service can now be deployed independently and scaled separately from the main Telegram bot application. --- TelegramSearchBot.OCR/Dockerfile | 28 +++++ TelegramSearchBot.OCR/Program.cs | 23 ++++ TelegramSearchBot.OCR/README.md | 84 ++++++++++++++ .../Services/OCRProcessingService.cs | 86 ++++++++++++++ .../Services/OCRWorkerService.cs | 104 +++++++++++++++++ .../TelegramSearchBot.OCR.csproj | 39 +++++++ TelegramSearchBot.OCR/appsettings.json | 19 +++ TelegramSearchBot.OCR/docker-compose.yml | 43 +++++++ TelegramSearchBot.sln | 6 + .../Service/AI/OCR/PaddleOCRService.cs | 39 +++++-- test-swarm-config.sh | 109 ++++++++++++++++++ 11 files changed, 573 insertions(+), 7 deletions(-) create mode 100644 TelegramSearchBot.OCR/Dockerfile create mode 100644 TelegramSearchBot.OCR/Program.cs create mode 100644 TelegramSearchBot.OCR/README.md create mode 100644 TelegramSearchBot.OCR/Services/OCRProcessingService.cs create mode 100644 TelegramSearchBot.OCR/Services/OCRWorkerService.cs create mode 100644 TelegramSearchBot.OCR/TelegramSearchBot.OCR.csproj create mode 100644 TelegramSearchBot.OCR/appsettings.json create mode 100644 TelegramSearchBot.OCR/docker-compose.yml create mode 100755 test-swarm-config.sh diff --git a/TelegramSearchBot.OCR/Dockerfile b/TelegramSearchBot.OCR/Dockerfile new file mode 100644 index 00000000..ef9135a5 --- /dev/null +++ b/TelegramSearchBot.OCR/Dockerfile @@ -0,0 +1,28 @@ +FROM mcr.microsoft.com/dotnet/aspnet:7.0 AS base +WORKDIR /app + +FROM mcr.microsoft.com/dotnet/sdk:7.0 AS build +WORKDIR /src +COPY ["TelegramSearchBot.OCR/TelegramSearchBot.OCR.csproj", "TelegramSearchBot.OCR/"] +COPY ["TelegramSearchBot.Common/TelegramSearchBot.Common.csproj", "TelegramSearchBot.Common/"] +RUN dotnet restore "TelegramSearchBot.OCR/TelegramSearchBot.OCR.csproj" +COPY . . +WORKDIR "/src/TelegramSearchBot.OCR" +RUN dotnet build "TelegramSearchBot.OCR.csproj" -c Release -o /app/build + +FROM build AS publish +RUN dotnet publish "TelegramSearchBot.OCR.csproj" -c Release -o /app/publish + +FROM base AS final +WORKDIR /app +COPY --from=publish /app/publish . + +# 安装OCR所需的依赖 +RUN apt-get update && apt-get install -y \ + libgdiplus \ + libc6-dev \ + libx11-dev \ + libfontconfig1 \ + && rm -rf /var/lib/apt/lists/* + +ENTRYPOINT ["dotnet", "TelegramSearchBot.OCR.dll"] \ No newline at end of file diff --git a/TelegramSearchBot.OCR/Program.cs b/TelegramSearchBot.OCR/Program.cs new file mode 100644 index 00000000..c88852bf --- /dev/null +++ b/TelegramSearchBot.OCR/Program.cs @@ -0,0 +1,23 @@ +using Microsoft.Extensions.DependencyInjection; +using Microsoft.Extensions.Hosting; +using Microsoft.Extensions.Logging; +using TelegramSearchBot.OCR.Services; + +namespace TelegramSearchBot.OCR { + public class Program { + public static async Task Main(string[] args) { + var host = Host.CreateDefaultBuilder(args) + .ConfigureServices((hostContext, services) => { + services.AddHostedService(); + services.AddSingleton(); + }) + .ConfigureLogging(logging => { + logging.AddConsole(); + logging.SetMinimumLevel(LogLevel.Information); + }) + .Build(); + + await host.RunAsync(); + } + } +} \ No newline at end of file diff --git a/TelegramSearchBot.OCR/README.md b/TelegramSearchBot.OCR/README.md new file mode 100644 index 00000000..914329f0 --- /dev/null +++ b/TelegramSearchBot.OCR/README.md @@ -0,0 +1,84 @@ +# TelegramSearchBot.OCR + +独立的OCR文字识别服务，基于PaddleOCR实现。 + +## 功能特性 + +- 基于PaddleOCR的中文文字识别 +- 通过Redis队列与主服务通信 +- 支持Docker容器化部署 +- 异步处理，支持并发控制 +- 自动重连和错误恢复 + +## 技术栈 + +- .NET 7.0 +- PaddleOCR +- OpenCV +- Redis +- Docker + +## 快速开始 + +### 本地运行 + +1. 确保已安装Redis并运行在localhost:6379 +2. 构建项目： + ```bash + dotnet build + ``` +3. 运行服务： + ```bash + dotnet run + ``` + +### Docker运行 + +1. 使用docker-compose启动： + ```bash + docker-compose up -d + ``` + +2. 单独构建和运行： + ```bash + docker build -t telegram-search-bot-ocr . + docker run -d --name ocr-service -e REDIS_HOST=your-redis-host telegram-search-bot-ocr + ``` + +## 配置 + +服务通过环境变量进行配置： + +- `REDIS_HOST`: Redis主机地址，默认localhost +- `REDIS_PORT`: Redis端口，默认6379 + +## 通信协议 + +服务通过Redis队列与主服务通信： + +1. 主服务将OCR任务推送到`OCRTasks`队列 +2.
