1:
ValueError: Expecting property name: line 1 column 1 (char 1)
类型的错误，就是由于JSON中，标准语法中，不支持单引号，
属性或者属性值，都必须是双引号括起来的。
所以，可以用类似于：
addedSingleQuoteJsonStr = re.sub(r "(,?)(\w+?)\s*?:" , r "\1'\2':" , orginalJsonStr); doubleQuotedJsonStr = addedSingleQuoteJsonStr.replace( "'" , "\"" ); 给属性添加单引号；
把所有的单引号替换成双引号；
