我使用正则表达式检查密码。但它没有按预期工作。我使用一些单元测试来检查正则表达式。
@implementation NSString (regexMatch)
- (BOOL)matchesRegex:(NSString *)regexPattern
{
NSError *error = nil;
NSRegularExpression* regex = [NSRegularExpression
regularExpressionWithPattern:regexPattern
options:NSRegularExpressionSearch
error:&error];
if(error)
{
NSLog(@"Error on maches regex: %@ on %@: %@", regex, self, error);
return NO;
}
NSUInteger maches = [regex numberOfMatchesInString:self
options:NSRegularExpressionSearch
range:NSMakeRange(0, [self length])];
return (maches > 0);
}
@end
正则表达式:
const static NSString *REGEX_VALID_PASS = @"(^((?=.*\\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[-_,.@#$%'\"]).{6,20})$)";
单元测试:
//Password
// At least:
// - between 6 and 20 chars
// - a capital character
// - a small character
// - a digit
// - a special char: - _ , . @ # $ % ´ '
STAssertTrue([@"Pass1-" matchesRegex:REGEX_VALID_PASS], @"Password 1 failed");
STAssertTrue([@"aPrettyLongPassw0rd@" matchesRegex:REGEX_VALID_PASS], @"Password 2 failed");
STAssertTrue([@"Pw987321-_,.@#$%'`" matchesRegex:REGEX_VALID_PASS], @"Password 3 failed");
//Returns TRUE ???
STAssertFalse([@"password1@" matchesRegex:REGEX_VALID_PASS], @"Wrong password 4 works (No capital letter)");
//Returns TRUE ???
STAssertFalse([@"PASSWORD2#" matchesRegex:REGEX_VALID_PASS], @"Wrong password 5 works (No small letter)");
STAssertFalse([@"Password8" matchesRegex:REGEX_VALID_PASS], @"Wrong password 6 works (No special letter)");
STAssertFalse([@"Password$" matchesRegex:REGEX_VALID_PASS], @"Wrong password 7 works (No digit letter)");
STAssertFalse([@"PrettyLongPasswordIsWrong123#" matchesRegex:REGEX_VALID_PASS], @"Wrong password 8 works (> 20)");
STAssertFalse([@"Pw@3" matchesRegex:REGEX_VALID_PASS], @"Wrong password 9 works (< 6)");
密码“password1@”和“PASSWORD2#”返回 TRUE,但不正确。
错误:
file://localhost/Users/user/app/AppTest.m: error: testRegex (AppTest) failed: "[@"password1@" matchesRegex:REGEX_VALID_PASS]" should be false. Wrong password 4 works (No capital letter)
and
file://localhost/Users/user/app/AppTest.m: error: testRegex (AppTest) failed: "[@"PASSWORD2#" matchesRegex:REGEX_VALID_PASS]" should be false. Wrong password 5 works (No small letter)
