问题 What is the best way to escape strings for sql inserts, updates? I want to allow special characters including ' and ". Is the best way to search and replace each string before I use it in an insert statement? Thanks Duplicate of: Best way to defend against mysql injection and cross site scripting 回答1: You should be using parameterized queries (so by extension, a DB interface library that supports parameterized queries) so that SQL injection can't happen. 回答2: If you're talking about data

问题 I hope that I have titled this question appropriately. Bit of a mixed subject here. I have created a function in C# that creates an Active Directory User. Using an LDAP string that needs to look like this: userinfo.displayName = "Surname, Firstname" CN=" + userinfo.displayName, "user" The following exception message is passed back, because of the comma being in the string. An invalid dn syntax has been specified. The full dn after the string has been applied is as following "CN=Surname**,**

问题 I have a field in one of my tables that contains this string: !"#¤%&/()=?´`?=)(/&%¤#"!\'\'"' (Only for test purposes ofcourse). I've tried endless of queries to properly select this field, and without returning any errors of course, but I just can't seem to get it right. This is the query I'm using currently: SELECT * FROM mytable WHERE `column` LIKE '%!"#¤%&/()=?´`?=)(/&%¤#"!\\\'\\\'"\'%' Can anyone shed some light on what it is I'm not doing right? Are there any other characters (other than

问题 I used BeautifulSoup to handle XML files that I have collected through a REST API. The responses contain HTML code, but BeautifulSoup escapes all the HTML tags so it can be displayed nicely. Unfortunately I need the HTML code. How would I go on about transforming the escaped HTML into proper markup? Help would be very much appreciated! 回答1: I think you want xml.sax.saxutils.unescape from the Python standard library. E.g.: >>> from xml.sax import saxutils as su >>> s = '<foo>bar</foo>' >>> su

问题 Does Flask's url_for method have an option to disable autoescaping? So if I have an endpoint called getUser with a route like this: /user/<userID> , I want to call url_for('getUser', userID='%') and have it return /user/% . Currently it will escape the % symobl and give out /user/%25 . I want to do that because url_for has to run at template compile-time, but the final URL is composed when a javscript script runs. I will be using a javascript string substitution method to convert /user/% into

问题 Confused about escape string and how it is stored in the database In my MySQL call, I escaping a string with a backslash: UPDATE `TABLE` SET `PERSONAL_BELONGINGS` = 'Tom\'s things' But when I look in the phpadmin - the value was saved like this: |Tom's things| Why is the backslash not saved into the database? This causes problems when I read this value into javascript and then try passing it around - my javascript strings will terminate. This is why I escaped the character to begin with. Why

问题 I have the following string and I'm trying to figure out the best practice for unescaping it. The solution has to be somewhat flexible in that I'm receiving this input from an API and I can't be absolutely certain that the current character structure ( \n as opposed to \r ) will always be the same. '"If it ain\'t broke, don\'t fix it." \nWent in for a detailed car wash.\nThe attendants raved-up my engine when taking the car into the tunnel. NOTE: my car is...' This regex seems like it should

问题 I have a Windows application and on events, it calls a command like this: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy Bypass "G:\test.ps1 -name '%x' -data '%y'" The name parameter sometimes has ' in it. Is it possible to escape that somehow? 回答1: This is actually a lot trickier than you'd think. Escaping nested quotes in strings passed from cmd to PowerShell is a major headache. What makes this one especially tricky is that you need to make the replacement in a

问题 I'm a bit confused with this issue! I'm building a bigger script and it was working in the ISE but not in a powershell console. I've managed to track it down to the [System.Uri]::EscapeDataString function which seems to be behaving differently between the different environments, for example in my powershell console () ' & ! are not being escaped, where as in the IDE they are all being escaped. Am I missing something? My test code: [System.Uri]::EscapeDataString("/?:@%!$&'/*+,;=()") ISE output
