这个是编码格式的异常，因为在爬虫元服务的对接中，通过http发送数据的时候，打包下来的数据封装的格式不对
string={'domain': 'android.myapp.com', 'url': 'https://android.myapp.com/myapp/searchAjax.htm?kw=MM%E5%BA%94%E7%94%A8%E5%95%86%E5%9C%BA&pns=&sid='}因为JSON中并没有单引号，仅有双引号，所以我们需要把单引号替换成双引号了
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes
方式有多种，比如用正则
data = re.sub('\'', '\"', string.decode("utf-8"))还可以同简单的字符串处理
string.replace('\"', '\'')以下是系统的异常抛出
