[英]trim non-ascii characters from string returned by nodejs crypto
I have successfully decrypted a sensitive data using nodejs crypto library. 我已经使用nodejs加密库成功解密了敏感数据。
The problem is that the decrypted data has a trailing non-ascii characters. 问题在于解密后的数据具有尾随的非ASCII字符。
How do I trim that? 我如何修剪呢?
My current trim function I below does not do the job. 我下面的当前修剪功能不起作用。
String.prototype.fulltrim = function () {
return this.replace( /(?:(?:^|\n)\s+|\s+(?:$|\n))/g, '' ).replace( /\s+/g, ' ' );
};
我认为跟随就足够了。
str.replace(/[^A-Za-z 0-9 \.,\?""!@#\$%\^&\*\(\)-_=\+;:<>\/\\\|\}\{\[\]`~]*/g, '') ;
Based on this answer , you can use: 根据此答案 ,您可以使用:
String.prototype.fulltrim = function () {
return this.replace( /([^\x00-\xFF]|\s)*$/g, '' );
};
This should remove all spaces and non-ascii characters at the end of the string, but leave them in the middle, for example: 这应删除字符串末尾的所有空格和非ASCII字符,但将其保留在中间,例如:
"Abcde ffאggg ג ב".fulltrim();
// "Abcde ffאggg";
