python js脚本特殊字解析报异常问题处理，execjs.compile

def _read_js_file():
    """
    读js文件
    :return: 返回js文件内容
    """
    f = open("decode.js", 'r', encoding='utf-8')  # 打开JS文件
    line = f.readline()
    str_file = ''
    while line:
        str_file = str_file + line
        line = f.readline()
    return str_file
__js_str =_read_js_file()
js_compile = execjs.compile(__js_str)
js_input ="=_省略.....;"
js_result = js_compile.call('decode', js_input)
print(js_result)

会提示：

SyntaxError: Non-UTF-8 code starting with '\xef' in file F:xxxx.py on line 34, but no encoding declared; see https://python.org/dev/peps/pep-0263/ for details

 

如下增加r，指定raw字符串，就可以成功执行js
