去json解码出错了。
其中column 179好像是:\x27
python json loads json.decoder.JSONDecodeError: Invalid \escape
Python json.loads fails with `ValueError: Invalid control character at: line 1 column 33 (char 33)` – Stack Overflow
试试:
productDict = json.loads(productJsonFiltered, strict=False)
结果问题依旧。

python中json报错JSONDecodeError: invalid control character – Richard_vim的博客 – CSDN博客
去试试encoding
productDict = json.loads(productJsonFiltered, strict=False, encoding="utf-8")
结果问题依旧。
考虑到此处的字符串中,除了:
\x27
还有其他特殊的:
  • \u002
  • \x26quot;
等特殊字符
-》所以还是想另外办法:
先去把productDescription的字符串的值,抽取出来,再去json.loads
然后对于提取出的productDescription的值,再去html解析,比如送到bs4中看看能否正常解析
此时,可以用代码:
        productMatch = re.search("^\s*product:\s*(?P<productJson>\{.+?\}$)", respText, re.S|re.M)
        print("productMatch=%s" % productMatch)
        if productMatch:
            productJson = productMatch.group("productJson")
            print("productJson=%s" % productJson)
            # productJson = productJson.replace("'", '"')
            productJsonFiltered = re.sub("^\s+(?P<keyName>\w+):", '"\g<keyName>":', productJson, flags=re.M)
            # productJsonFiltered = productJsonFiltered.replace("'", '"')
            productJsonFiltered = productJsonFiltered.replace("''", '""')
            print("productJsonFiltered=%s" % productJsonFiltered)
            descriptionValueMatch = re.search('"productDescription":\s*"(?P<descriptionValue>.+?)",', productJsonFiltered)
            print("descriptionValueMatch=%s" % descriptionValueMatch)
            if descriptionValueMatch:
                descriptionValue = descriptionValueMatch.group("descriptionValue")
                print("descriptionValue=%s" % descriptionValue)

                descriptionValueFiltered = descriptionValue.replace("\/", "/")
                print("descriptionValueFiltered=%s" % descriptionValueFiltered)
                description = htmlToString(descriptionValueFiltered)
                print("description=%s" % description)

                productJsonFiltered = productJsonFiltered.replace(descriptionValue, "")
                print("productJsonFiltered=%s" % productJsonFiltered)


            # productDict = json.loads(productJsonFiltered)
            # productDict = json.loads(productJsonFiltered, strict=False)
            productDict = json.loads(productJsonFiltered, strict=False, encoding="utf-8")
            print("productDict=%s" % productDict)
基本上得到我们要的dict对象,以及包含html的entity的了:
