前言

自从换了Macbook Pro后，一直想在电脑用上Chat GPT帮我翻译，虽然有了Bob这个翻译软件 + Mac自带翻译，感觉还是差点意思，总是有些句子翻译的不是很好，几句话一起翻译直接摆烂，我真的是服了。后面在网上找了一圈，还真有大佬搞出了个Bob里面的第三方接入ChatGPT翻译的插件，看了一遍代码，写的挺简单，但是JS我是真的没怎么搞过，心想就算了吧。搞搞API绑卡也就算了。说到API绑卡这个，我直接一直用Depay绑卡都被拒绝，后面进了Telegram官方群后，一张管理员发的图片帮了我。我也发到这里吧。
a954e7792ea16848fadb161c1b7f0311.png

后面逛着GitHub时偶然发现有个Python版本的网页ChatGPT API，我心想，不然我把翻译插件的网址调用自己电脑上服务器（类似伪基站，中间人），然后服务器在调用ChatGPT平台不就完事了嘛！

方案

当时我方案一下就想好了，就Flask + Docker。我也担心写这玩意用的时间多，索性试试ChatGPT写小工程可以不可以。
方案如下：

  1. 测试ChatGPT Python API，封装成函数，除了这个没用GPT，剩下都有使用到ChatGPT，主要是测试能不能用。
  2. 让ChatGPT帮我把JS前端的链接部分放入Python当中。这一步等下我直接演示步骤。
  3. 接入第一步封装函数。
  4. 封装Dockerfile以及Docker-compose，做调整。

方案第二步：JS To Python

以下是ChatGPT交流内容1，代码写出来了，但是Debug有点脑壳疼。

      type: reason,
      message: `接口响应错误 - ${resp.data.error.message}`,
      addition: JSON.stringify(resp),
    },
  });
} else {
  const { result } = resp.data;
  if (!result) {
    completion({
      error: {
        type: "api",
        message: "接口未返回结果",
      },
    });
    return;
  }
  completion({
    result: {
      from: result.from,
      to: result.to,
      toParagraphs: result.toParagraphs,
    },
  });
}

})().catch((err) => {
completion({
error: {
type: err._type || “unknown”,
message: err._message || “未知错误”,
addition: err._addition,
},
});
});
}

exports.supportLanguages = supportLanguages;
exports.translate = translate;

现在，我们已经修改了前端JavaScript代码，使其与新的Flask服务器进行通信。这里的主要更改是向Flask服务器发送POST请求，并传递与之前代码相同的数据。然后，我们处理Flask服务器的响应并返回相应的结果。这样一来，前端代码就可以继续使用`translate`函数，而不需要关心后端实现的细节。

抱歉，看起来在提取请求数据时出现了问题。请尝试将以下代码替换为当前的`translate()`函数，以确保正确处理输入数据。

python

```python
def translate():
    data = request.get_json(force=True)

    # Check if the required data is available in the request
    if not data or 'query' not in data or 'option' not in data:
        return jsonify({"error": {"type": "param", "message": "缺少必要的输入数据"}}), 400

    query = data['query']
    option = data['option']

    # ... the rest of the translate() function remains unchanged ...

这个修改使用request.get_json(force=True)确保即使没有设置正确的Content-Type头，也能从请求中获取JSON数据。另外，我们还检查了请求中是否包含必要的query和option数据，如果缺少数据，则返回一个包含错误信息的JSON响应。

不要替换前端代码，只修改python后端代码

    if not data or 'query' not in data or 'option' not in data:
        return jsonify({"error": {"type": "param", "message": "缺少必要的输入数据"}}), 400

    query = data['query']
    option = data['option']
    system_prompt = data.get('systemPrompt')
    user_prompt = data.get('userPrompt')

    # ... the rest of the translate() function remains unchanged ...

使用这个修改后的代码运行Flask服务器，然后再次尝试从前端发起请求。现在，每次请求到达时，服务器都会在控制台输出接收到的数据。这将帮助您识别可能的问题。如果您在输出中发现了问题，请在此处提供相关信息，以便我为您提供进一步的帮助。

的问题。如果您在输出中发现了问题，请在此处提供相关信息，以便我为您提供进一步的帮助。

运行这个修改后的Flask服务器代码，请确保在Python环境中安装了所需的依赖项，比如Flask和requests库。在终端中，您可以使用以下命令安装这些库（如果还没有安装）：

sh

1
pip install flask requests

然后，在包含Flask服务器代码的文件夹中运行以下命令启动服务器：

sh

1
python <your_server_filename>.py

例如，如果您将代码保存在名为app.py的文件中，则运行python app.py。

启动服务器后，您可以通过前端发起请求来测试后端。观察控制台输出，看看是否可以找到导致问题的原因。如果有任何疑问或需要进一步的帮助，请随时在此处提问。

将此代码替换到您的Flask服务器文件中，然后运行服务器并测试前端请求。这个修改后的代码应该可以正常工作。如果您遇到任何问题，请随时在此处提问，以便我能为您提供进一步的帮助。

经过再次审查，我发现问题可能在于从前端发送到后端的数据格式上。后端代码似乎无法正确地解析前端发送的数据。为了解决这个问题，我们将在后端代码中添加一些额外的调试信息以找出问题。我还注意到您要求去掉def translate之前的内容。这段代码为前端提供了一个翻译API，因此我们需要保留它。

请尝试将以下代码替换为您的 Flask 服务器代码：

现在，请再次运行此代码。此次，您应该能在控制台看到一些额外的调试输出，其中包括从前端收到的数据以及从中提取的查询数据。如果您仍然遇到问题，请提供此额外的调试输出，以便我们更好地了解问题所在并提供解决方案。

这个是第二次对话，因为我感觉上一个对话它会把自己搞懵逼了。

从你提供的Python后端代码和错误日志来看，问题可能出在传递给GPT的数据上。在你的Python后端代码中，你需要确保从前端接收到的数据包含必需的字段。在这种情况下，model, api_url, api_url_path, 和 api_keys 字段似乎没有正确传递给后端。你需要确保这些字段在请求中包含。

首先，你需要修改你的JavaScript代码中的translate函数，将这些选项添加到传递给Python后端的请求中。你可以通过将它们添加到body对象来实现这一点：

javascript

1
2
3
body["api_url"] = $option.api_url;
body["api_url_path"] = apiUrlPath;
body["api_keys"] = $option.api_keys;

然后，在Python后端，你需要从请求数据中提取这些选项。你可以使用以下代码替换你现有的option = data行：

python

1
2
3
4
5
6
7
option = {
    'model': data.get('model'),
    'api_url': data.get('api_url'),
    'api_url_path': data.get('api_url_path'),
    'api_keys': data.get('api_keys'),
    'messages': data.get('messages')
}

这样，你应该能够从前端将所有必需的选项传递给Python后端，并正确处理请求。

另外，请注意，你的Python后端代码中的translate函数与JavaScript代码中的translate函数不匹配。这可能会导致问题。你需要确保你的Python后端代码接收到的数据与JavaScript代码中发送的数据匹配。

只修改后端代码，不修改前端代码，把python代码全部写出来

好的，为了不修改前端代码，我们可以从原始请求数据中提取缺失的选项。下面是修改后的Python后端代码：

这段代码主要修改了以下几点：

1. 从请求头中提取API密钥。
2. 如果前端没有提供`api_url`和`api_url_path`，则使用默认值。
3. 其余部分与之前的代码相同。

这样，后端代码就可以与您提供的前端代码一起正常工作了。

我感觉到上一个对话还是有问题，就切换到下一个，也是最后一个，它把自己的BUG修复了。

从报错信息来看，问题出在发送到后端的数据缺少必要的输入数据。具体来说，后端代码期望在 messages 中有两个用户消息：一个表示翻译方向，另一个是要翻译的文本。然而，从你提供的错误日志中，我们可以看到，messages 列表中只有一个用户消息，即表示翻译方向的消息。

要解决这个问题，你需要在 Python 后端代码中稍作修改以适应前端发来的数据。具体来说，你需要修改 translate 函数中提取 query 数据的部分，使其能够正确处理只有一个用户消息的情况。

下面是修改过的代码：

python

# Extract the query data from the messages
user_messages = [message for message in option['messages'] if message['role'] == 'user']
if not user_messages or len(user_messages) < 1:
    return jsonify({"error": {"type": "param", "message": "缺少必要的输入数据"}}), 400

query = {
    'text': user_messages[-1]['content'].split('=>')[1].strip(' "'),
    'detectFrom': user_messages[-1]['content'].split()[2],
    'detectTo': user_messages[-1]['content'].split()[4]
}
print("Query data:", query)  # Temporary print statement to debug the extracted query data

这个修改后的代码会检查是否有至少一个用户消息，然后从这个消息中提取翻译方向和要翻译的文本。这样一来，后端应该能够正确处理从前端收到的数据了。

第三步：结合

对话只有一个。

            'content': 'translate from en to zh-CN:\n\n"status code" =>',
            'role': 'user'
        }
    ],
    'frequency_penalty': 1,
    'model': 'gpt-3.5-turbo',
    'temperature': 0,
    'presence_penalty': 1,
    'top_p': 1,
    'max_tokens': 1000
}

# 从输入中提取内容并合并
content_to_translate = extract_content(input_data)

# 将内容传递给 chat_with_gpt 函数（此处需要实现与 GPT 交互的逻辑）
translated_content = chat_with_gpt(content_to_translate)

# 对输出的字符串进行封装
output_data = wrap_output_content(translated_content)

# 将输出数据转换为 JSON 格式
output_json = json.dumps(output_data, ensure_ascii=False, indent=4)
print(output_json)

请注意，您需要在chat_with_gpt函数中添加与GPT交互的逻辑。根据您的输入和输出格式，我已为您提供了从输入中提取内容、合并内容、调用chat_with_gpt函数以及封装输出的完整流程。

第四步，Docker部分

Model: GPT-4

1 / 1

写一个Dockerfile构建Flask服务器，里面需要import的模块如下：`from revChatGPT.V1 import Chatbot import copy from flask import Flask, request, jsonify import requests import json`

1 / 1

以下是一个简单的Dockerfile，用于构建一个包含所需模块的Flask服务器：

# 使用官方的Python基础镜像作为基础
FROM python:3.8-slim

# 设置工作目录
WORKDIR /app

# 将requirements.txt文件复制到工作目录
COPY requirements.txt requirements.txt

# 安装任何需要的包
RUN pip install --trusted-host pypi.python.org -r requirements.txt

# 将当前目录的内容复制到容器的/app目录
COPY . /app

# 使端口80可用于该容器之外
EXPOSE 80

# 定义环境变量
ENV NAME World

# 运行app.py，启动服务器
CMD ["python", "app.py"]

同时，请在您的项目目录中创建一个名为requirements.txt的文件，其中包含您需要安装的Python包。根据您提供的代码，您需要以下包：

Flask requests

注意，我没有在requirements.txt文件中包含revChatGPT.V1，因为这似乎是您自己的模块。请确保将该模块与app.py放在同一目录下，并在Docker容器中适当地导入它。

最后，在包含Dockerfile的目录中运行以下命令以构建和运行Docker容器：

arduino

1
2
docker build -t your-image-name .
docker run -p 4000:80 your-image-name

这将使用Dockerfile构建一个名为your-image-name的镜像，并将容器的80端口映射到宿主机的4000端口。之后，您可以通过访问http://localhost:4000来访问您的Flask服务器。

1 / 1

有两个问题：1、没有“requirements.txt”。2、环境定义变量去掉，后面通过容器调用在进行定义，重新修改一下Dockerfile

1 / 1

根据您的要求，我已去掉了requirements.txt文件并删除了环境变量定义。以下是修改后的Dockerfile：

Dockerfile

# 使用官方的Python基础镜像作为基础

# 设置工作目录
WORKDIR /app

# 安装所需的Python包
RUN pip install --trusted-host pypi.python.org Flask requests

# 将当前目录的内容复制到容器的/app目录
COPY . /app

# 使端口80可用于该容器之外
EXPOSE 80

# 运行app.py，启动服务器
CMD ["python", "app.py"]

现在，Dockerfile会直接安装Flask和requests包，而不再依赖于requirements.txt文件。同时，我已移除了环境变量定义，您可以在运行容器时通过命令行参数来设置环境变量。

在包含Dockerfile的目录中运行以下命令以构建和运行Docker容器：

arduino

1
2
docker build -t your-image-name .
docker run -p 4000:80 -e NAME=World your-image-name

这将使用Dockerfile构建一个名为your-image-name的镜像，并将容器的80端口映射到宿主机的4000端口。在这个例子中，我们使用-e参数设置了环境变量NAME。您可以通过访问http://localhost:4000来访问您的Flask服务器。

1 / 1

通过上面，构建一个Docker Compose文件，环境变量写到.env文件中

1 / 1

首先，创建一个名为.env的文件来存储您的环境变量。在本例中，我们将设置NAME环境变量：

makefile

1
NAME=World

接下来，创建一个名为docker-compose.yml的文件，并使用以下内容定义您的服务：

yaml

1

version: '3.8'

services:
  flask_app:
    build: .
    image: your-image-name
    ports:
      - "4000:80"
    env_file:
      - .env

这个docker-compose.yml文件定义了一个名为flask_app的服务，它将使用您之前创建的Dockerfile进行构建。将容器的80端口映射到宿主机的4000端口，并通过env_file指令将.env文件中定义的环境变量加载到容器中。

要使用Docker Compose构建并运行服务，请在包含docker-compose.yml文件的目录中运行以下命令：

css

1
docker-compose up --build

Docker Compose将根据docker-compose.yml文件构建镜像并启动服务。您可以通过访问http://localhost:4000来访问您的Flask服务器。要停止服务并删除容器，请使用以下命令：

docker-compose down

1 / 1

DockerCompose文件当中端口从4000改成5000

1 / 1

要将端口从4000更改为5000，只需在docker-compose.yml文件中修改ports部分。请参考以下修改后的docker-compose.yml：

yaml

1

version: '3.8'

services:
  flask_app:
    build: .
    image: your-image-name
    ports:
      - "5000:80"
    env_file:
      - .env

现在，容器的80端口将映射到宿主机的5000端口。要使用Docker Compose构建并运行服务，请确保您位于包含docker-compose.yml文件的目录中，然后运行以下命令：

css

1
docker-compose up --build

Docker Compose将根据docker-compose.yml文件构建镜像并启动服务。您可以通过访问http://localhost:5000来访问您的Flask服务器。要停止服务并删除容器，请使用以下命令：

docker-compose down
