Valid Email Addresses - XSS and SQL Injection

阅读更多关于 Valid Email Addresses - XSS and SQL Injection

问题 Since there are so many valid characters for email addresses, are there any valid email addresses that can in themselves be XSS attacks or SQL injections? I couldn't find any information on this on the web. The local-part of the e-mail address may use any of these ASCII characters: Uppercase and lowercase English letters (a–z, A–Z) Digits 0 to 9 Characters ! # $ % & ' * + - / = ? ^ _ ` { | } ~ Character . (dot, period, full stop) provided that it is not the last character, and provided also

List of mock valid/invalid Email Addresses for Unit Tests

阅读更多关于 List of mock valid/invalid Email Addresses for Unit Tests

问题 Does anyone know of a list of email addresses (which don’t need to be real) I can use for an email validation assembly for a unit test? I’ve been looking for such a list and can’t seem to find one. I’m not looking for real addresses, just ones that fit, and the more things I can throw at the test the better. I’ve got 10 right now, but if there is a list, it would give me a more thorough test. 回答1: I believe you were looking for something like this: List of Valid and Invalid Email Addresses

Why does PHP filter_var say that this is a valid email address?

阅读更多关于 Why does PHP filter_var say that this is a valid email address?

问题 I use the filter_var PHP function to validate email address when a user signs up to my site. I use this code from the post: $email = filter_var($_POST['email'], FILTER_VALIDATE_EMAIL); then later I do: if(!$email) { // return to the form } else { // send registration info } now when I var_dump($email) , I get the output: string(23) "user."name"@example.com" I would like to know why this does not return false. I think the double quotes are not acceptable, so why does PHP say it’s valid? 回答1:

I pretty much did well on Email verification and such things, but one problem, I'm encountering is that "how to validate" entered email address?

问题 Array ( [0] => myemail@domain.com [1] => mysecondemail@domain.com [2] => invalidEmail.com ) Notice that the third array value is invalid email format. How do I remove it by using/creating a function?

Regular exp to validate email in C

阅读更多关于 Regular exp to validate email in C

We need to write a email validation program in C. We are planning to use GNU Cregex.h) regular expression. The regular expression we prepared is [a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])? But the below code is failing while compiling the regex. #include <stdio.h> #include <regex.h> int main(const char *argv, int argc) { const char *reg_exp = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"; int status = 1; char email[71]

Is it a bad idea to automatically log users in from an email?

阅读更多关于 Is it a bad idea to automatically log users in from an email?

问题 For many of the sites we develop, we verify the user's email address. Typically the workflow is such: User registers for site (activation email is sent with link to activate) User verifies email address (by clicking aforementioned link) User must log in to site in order to use it (assuming they weren't already logged in) Clients often complain about this process being clunky and somewhat confusing, and I agree. The proposed solution is to remove step 3 and automatically log the user in after

How to force users to use email address in lowercase in GIT

阅读更多关于 How to force users to use email address in lowercase in GIT

问题 I'm looking for possibilities to confirm whether the email address of the committer is lower case to avoid issues like this. I'm thinking to implement a client side pre-commit hook script which would either convert the upper case into lower case characters in the username and email or just warns the user to change in git config. I don't want to write something like this every time I encounter with errors during import. This is not recommended, as it results in modification in the ref values

What's the REST way to verify an email?

问题 When a user register to my web application I send an email to verify his inbox. In the email there are a link to a resource like this: GET /verify/{token} Since the resource is being updated behind the scenes, doesn't it break the RESTful approach? How can I do it in a RESTful manner? 回答1: What you are talking about is not REST. REST is for machine to machine communication and not for human to machine communication. You can develop a 1st party REST client, which sends the activation to the

问题 According to RegExp documentation, we must use "JavaScript" (Perl 5) regular expressions : Ecma Specification. What pattern do you use for email validation? 回答1: I'd recommend everyone standardize on the HTML5 email validation spec, which differs from RFC822 by disallowing several very seldom-used features of email addresses (like comments!), but can be recognized by regexes. Here's the section on email validation in the HTML5 spec: http://www.whatwg.org/specs/web-apps/current-work/multipage
