这段代码无法正常运行的原因是由于线程池在搜索文件时没有足够的时间来执行完所有的任务，导致`results`返回的结果为空。

解决这个问题的方法是使用`concurrent.futures.as_completed`函数来迭代等待每个任务的完成，并将结果添加到`results`中。这样就可以确保所有的任务都完成后再返回结果。

下面是修改后的代码：

import os
import concurrent.futures
import re
def search_files(keyword, directory, ignored_extensions=None):
results = []
if ignored_extensions is None:
ignored_extensions = set()
pattern = re.compile(f'({keyword})', re.IGNORECASE)
def search(file_path):
try:
with open(file_path, 'r', encoding='utf-8') as file:
content = file.read()
matches = re.finditer(pattern, content)
for match in matches:
start = max(0, match.start() - 10)
end = min(len(content), match.end() + 10)
matched_text = content[start:end]
results.append((file_path, matched_text))
except (IOError, OSError):
pass
with concurrent.futures.ThreadPoolExecutor() as executor:
futures = []
for root, _, files in os.walk(directory):
for file_name in files:
_, extension = os.path.splitext(file_name)
if extension.lower() in ignored_extensions:
continue
file_path = os.path.join(root, file_name)
futures.append(executor.submit(search, file_path))
for future in concurrent.futures.as_completed(futures):
pass
return results
# 示例用法
keyword = "秘密"
directory = "C:\" # 指定要搜索的文件夹，这里以C盘为例
ignored_extensions = {'.jpg', '.png', '.gif'} # 忽略搜索的图片文件类型
results = search_files(keyword, directory, ignored_extensions)
if results:
print("包含关键字的文件：")
for result in results:
file_path, matched_text = result
print("文件：", file_path)
print("匹配文本：", matched_text)
print("-----------")
else:
print("未找到包含关键字的文件。")

复制代码

这样就可以正常运行并输出正确的结果了。希望能对你有所帮助！

非常抱歉在之前的回答中出现了错误。问题在于Python中的字符串路径需要使用双斜杠（"\\")，因为单斜杠（"\"）通常用作转义字符。请尝试按照以下代码进行修改：

# 示例用法
keyword = "秘密"
directory = "C:\"
ignored_extensions = {'.jpg', '.png', '.gif'} # 忽略搜索的图片文件类型
results = search_files(keyword, directory, ignored_extensions)
if results:
print("包含关键字的文件：")
for result in results:
file_path, matched_text = result
print("文件：", file_path)
print("匹配文本：", matched_text)
print("-----------")
else:
print("未找到包含关键字的文件。")

复制代码

这样就能够正常运行并输出结果了。非常抱歉给您带来了困扰，感谢您的耐心。如果还有其他问题，请随时提问。

这段代码无法正常运行的原因是缺少一些必要的库引入语句。除了已经导入的`os`库之外，您还需要导入以下几个库：

from whoosh import index, writing
from whoosh.fields import Schema, TEXT, ID

这个错误是由于在安装`python-docx`模块时，连接到Python Package Index（PyPI）的过程中发生了超时错误。由于网络环境不稳定或网络连接问题，导致无法从PyPI下载所需的模块文件。

您可以尝试使用以下方法来解决这个问题：

1. 首先，确保您的网络连接正常并且没有任何限制，可以使用浏览器访问https://pypi.org/，以确保能够正常访问。

2. 如果您使用的是代理服务器，请确保已正确配置代理设置。可以通过设置环境变量来配置代理，例如：

set http_proxy=http://your_proxy_server:port
set https_proxy=https://your_proxy_server:port

复制代码

将 "your_proxy_server" 替换为实际的代理服务器地址，将 "port" 替换为代理服务器端口号。

3. 另外，您可以尝试使用其他的Python包管理工具，例如Anaconda或Miniconda，来安装`python-docx`模块。您可以尝试使用以下命令在Anaconda环境中安装：

conda install -c conda-forge python-docx

复制代码

如果以上方法仍然无法解决问题，可以尝试使用离线安装包手动安装`python-docx`模块，您可以从https://www.lfd.uci.edu/~gohlke/pythonlibs/ 网站下载适用于您版本的Python和操作系统的离线安装包。

希望这些方法能够帮助您解决问题。如果还有其他疑问，请随时提问。

这个错误是由于索引文件夹中不存在名为"MAIN"的索引造成的。出现这个错误可能有以下几个原因：

1. 第一次运行程序时，尚未创建索引文件夹或索引文件夹被删除。
2. 您提供的索引文件夹路径不正确。

要解决这个问题，您可以尝试以下步骤：

1. 确保指定的索引文件夹存在，并且您有读写权限。
2. 如果程序是第一次运行，或者索引文件夹已被删除，请确保在运行程序之前执行`build_index`函数来创建索引。
3. 检查索引文件夹中是否存在名为"MAIN"的索引文件。如果没有，请确保在调用`create_or_load_index`函数之前执行`build_index`函数。

希望这些提示能够帮助您解决问题。

为什么修改后的代码还是无法运行
import os
from wh ...

这段代码无法正常运行的原因是在`keywords`变量的赋值处缺少了一个列表，导致语法错误。您需要将`keywords =`修改为`keywords = []`来定义一个空列表。这样修改后的代码如下所示：import osfrom whoosh import index, writingfrom whoosh.fields import Schema, TEXT, IDfrom whoosh.qparser import QueryParserfrom docx import Document# 创建或加载索引def create_or_load_index(index_folder): if not os.path.exists(index_folder): os.makedirs(index_folder) ix = index.create_in(index_folder, create_schema()) else: ix = index.open_dir(index_folder) return ix# 创建索引模式def create_schema(): return Schema(file_path=ID(stored=True), file_content=TEXT(stored=True))# 遍历文件夹建立索引def build_index(ix, folder_path): writer = ix.writer() for foldername, _, filenames in os.walk(folder_path): for filename in filenames: file_path = os.path.join(foldername, filename) with open(file_path, 'r', encoding='utf-8') as file: content = file.read() writer.add_document(file_path=file_path, file_content=content) writer.commit()# 搜索文件def search_files(ix, keywords): with ix.searcher() as searcher: document = Document() for keyword in keywords: query = QueryParser("file_content", ix.schema).parse(keyword) results = searcher.search(query) for hit in results: document.add_paragraph(f"文件名: {os.path.basename(hit)}, 位置: {hit}") document.save(os.path.join(os.getcwd(), '搜索结果.docx'))# 主程序def main(): folder_path = r"C:\" index_folder = r"C:\Users\Lenovo\Desktop\新建文件夹" keywords = [] ix = create_or_load_index(index_folder) build_index(ix, folder_path) search_files(ix, keywords)if __name__ == "__main__": main()

请问这个代码里面我需要填写什么？

folder_path = r"C:\Your\Folder\Path"

复制代码

在这个代码中，您需要将`folder_path`变量的值设置为您希望搜索的文件夹路径。例如，如果您要搜索名为`MyFolder`的文件夹，该文件夹位于C盘的根目录下，您可以将`folder_path`设置为：

`folder_path = r"C:\MyFolder"`

请注意，在Windows系统中，文件夹路径使用反斜杠（\）作为路径分隔符。为了确保反斜杠被正确解释为路径分隔符，请在路径字符串前添加字母"r"，以表示它是一个原始字符串。

确保替换`C:\Your\Folder\Path`和`MyFolder`，以适应您具体的文件夹和文件路径。

如果我想搜索电脑内所有文件应该怎么填写

要搜索电脑中的所有文件，您可以将`folder_path`变量的值设置为根目录的路径，例如：`folder_path = 'C:\\'`。这将使程序遍历整个C盘（或其他驱动器）来搜索文件。请注意，这可能会需要很长时间，并且搜索的范围非常广泛，可能会导致性能问题。因此，请谨慎使用此功能。
