看你贴的代码，你已经修改配置了呀？然后命令行运行这段python代码，挂在后端就好了。 |
|
第一个问题：运行脚本以后（修改部分为8888改为7860），
translatetranslating ###: G:/OneDrive/Zotero/Storage/IEE IEEE_VTS_Challenge/2023/Pre_2018_Model Based Energy Management and State Estimation for the Robotic Electric Vehicle ROboMObil.pdfTraceback (most recent call last): translatetranslating ###: G:/OneDrive/Zotero/Storage/IEE IEEE_VTS_Challenge/2023/Pre_2018_Model Based Energy Management and State Estimation for the Robotic Electric Vehicle ROboMObil.pdfTraceback (most recent call last): |
|
这个不需要在浏览器打开，挂在后台就好了。 |
|
我将pdf2zh安装在通过conda创建的虚拟环境里面，如果通过激活conda环境后，使用pdf2zh -i 可以在浏览器正常使用，也能正常翻译。 |
|
你可以试试打开命令行工具(cmd)，先在命令行激活虚拟环境，然后在命令行工具里执行这个脚本试试。 或者尝试另一个方法： |
我想请问第一步的脚本配置怎么实现
具体操作步骤是什么
from flask import Flask, request, jsonify
import os
import base64
import subprocess
from flask import Flask, send_file, abort
from pypdf import PdfWriter, PdfReader
from pypdf.generic import RectangleObject
import sys
####################################### 配置 #######################################
pdf2zh = "pdf2zh" # 设置pdf2zh指令: 默认为'pdf2zh'
thread_num = 4 # 设置线程数: 默认为4
port_num = 7860 # 设置端口号: 默认为8888
service = 'bing' # 设置翻译服务: 默认为bing
translated_dir = "./translated/" # 设置翻译文件的输出路径(临时路径, 可以在翻译后删除)
config_path = './config.json' # 设置配置文件路径
######################################################################################
def get_absolute_path(path): # 获取绝对路径
if os.path.isabs(path):
return path
else:
return os.path.abspath(path)
def get_file_from_request(request): # 从request中解析pdf文件
data = request.get_json()
path = data.get('filePath')
path = path.replace('\', '/') # 把所有反斜杠\替换为正斜杠/ (Windows->Linux/MacOS)
if not os.path.exists(path):
file_content = data.get('fileContent')
input_path = os.path.join(translated_dir, os.path.basename(path))
if file_content:
if file_content.startswith('data:application/pdf;base64,'): # 移除 Base64 编码中的前缀(如果有)
file_content = file_content[len('data:application/pdf;base64,'):]
file_data = base64.b64decode(file_content) # 解码 Base64 内容
with open(input_path, 'wb') as f:
f.write(file_data)
else:
input_path = path
return input_path
app = Flask(name)
@app.route('/translate', methods=['POST'])
def translate():
print("### translate ###")
input_path = get_file_from_request(request)
try:
os.makedirs(translated_dir, exist_ok=True)
print("### translating ###: ", input_path)
@app.route('/translatedFile/')
def download(filename):
directory = translated_dir
abs_directory = get_absolute_path(directory)
file_path = os.path.join(abs_directory, filename)
if not os.path.isfile(file_path):
return "File not found", 404
return send_file(file_path, as_attachment=True, download_name=filename)
新增了一个cut pdf函数，用于切割双栏pdf文件
def split_and_merge_pdf(input_pdf, output_pdf):
writer = PdfWriter()
if 'dual' in input_pdf:
reader1_1 = PdfReader(input_pdf)
reader1_2 = PdfReader(input_pdf)
reader2_1 = PdfReader(input_pdf)
reader2_2 = PdfReader(input_pdf)
for i in range(0, len(reader1_1.pages), 2):
page1_1 = reader1_1.pages[i]
page1_2 = reader1_2.pages[i]
page2_1 = reader2_1.pages[i+1]
page2_2 = reader2_2.pages[i+1]
新增了一个cut接口，用于切割双栏pdf文件
@app.route('/cut', methods=['POST'])
def cut():
print("### cut ###")
input_path = get_file_from_request(request)
try:
os.makedirs(translated_dir, exist_ok=True)
print("### cutting ###: ", input_path)
abs_translated_dir = get_absolute_path(translated_dir)
translated_path = os.path.join(abs_translated_dir, os.path.basename(input_path).replace('.pdf', '-cut.pdf'))
split_and_merge_pdf(input_path, translated_path)
if not os.path.exists(translated_path):
raise Exception("failed to generate cutted files")
return jsonify({'status': 'success'}), 200
except Exception as e:
print(f"Error: {e}")
return jsonify({'status': 'error', 'message': str(e)}), 500
if name == 'main':
if len(sys.argv) > 1: # 命令行参数1: service
service = sys.argv[1]
if len(sys.argv) > 2: # 命令行参数2: thread_num
thread_num = int(sys.argv[2])
app.run(host='0.0.0.0', port=port_num)
