如何使用正则表达式从单行 JSON 文本文件中提取 URL？

[英]How can I extract URLs from a one line JSON text file using regex?

问题描述

我一直在努力解决这个问题，但我似乎只能将一个 URL 导出到输出文件。

我目前使用的代码是...

import glob, re

with open('urls.txt', 'a') as output:
    for file in glob.glob('json.txt'):
        with open(file, 'r') as f:
            for line in f.readlines():
                pattern = r"(http|ftp|https):\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])"
                find = re.findall(pattern, line)
                if find:
                    try:
                        output.write(str(find[0]))
                    except UnicodeEncodeError:
                        pass

我已经测试了正则表达式代码，它能够匹配所有的 URL，只是不会将它们全部输出到文件中。

我一直试图从中提取 URL 的文件包含以下内容（为了便于阅读而缩进）：

我认为让您拥有有效 JSON 的数据然后使用json.loads()支持的object_hook参数可能会更容易。 有关更多详细信息，请参阅我对如何按键查找特定 JSON 值的回答？ .

以下是如何应用您的数据：

import json

def find_values(id, json_repr):
    results = []

    def _decode_dict(a_dict):
        try:
            results.append(a_dict[id])
        except KeyError:
            pass
        return a_dict

    json.loads(json_repr, object_hook=_decode_dict) # Return value ignored.
    return results

with open('filename.json') as file:
    jstr = file.read()

json_repr = jstr + ']}'  # Make jstr valid JSON.

results = find_values('url', json_repr)
print(f'{len(results)} URLs found')
for i, url in enumerate(results, start=1):
    print(f'{i}: {url}')

输出：

3 URLs found

正如其他人所提到的，有更好的方法来解析/读取 json，但是给定您的代码，它可以通过一个小的调整来完成您想要的。

import glob, re

with open('urls.txt', 'a') as output:
    for file in glob.glob('json.txt'):
        with open(file, 'r') as f:
            for line in f.readlines():
                pattern = r"(http|ftp|https):\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])"
                find = re.findall(pattern, line)
                if find:
                    try:
                        for result in find:
                            output.write(str(result) + "\n")
                    except UnicodeEncodeError:
                        pass

您只要求输出第一个匹配的结果（ find[0] ）。 你想得到所有这些，所以遍历它们然后输出它们。
