SecKeychainFindInternetPassword不工作
SecKeychainFindInternetPassword不工作
提问于 2012-11-23 22:28:29
我在存储和读取我的钥匙链时遇到了问题。首先，我尝试在accountname的方法SecKeychainFindInternetPassword中使用类似于"account_name“的字符进行存储，并运行此命令。但是现在我想在里面存储一个变量。但是如果我运行这段代码，程序员就无法找到Keychain项。请帮帮我。(对不起，我的英语不好，我是一名德国学生)
-(void)StorePasswordKeychain:(void*)password :(UInt32)passwordLength
{
char *userString;
userString = (char *)[_username UTF8String];
SecKeychainAddInternetPassword(
NULL,
StrLength("myserver.com"),
"myserver.com",
0,
NULL,
StrLength(userString),
userString,
0,
nil,
0,
kSecProtocolTypeHTTPS,
kSecAuthenticationTypeHTMLForm,
passwordLength,
password,
NULL
);
}
-(OSStatus)GetPasswordKeychain:(void *)passwordData :(UInt32 *)passwordLength
{
OSStatus status;
char *userString;
userString = (char *)[_username UTF8String];
status = SecKeychainFindInternetPassword(
NULL,
StrLength("myserver.com"),
"myserver.com",
0,
NULL,
StrLength(userString),
userString,
0,
nil,
0,
kSecProtocolTypeHTTPS,
kSecAuthenticationTypeHTMLForm,
passwordLength,
passwordData,
NULL
);
return status;

有两个建议..不要将null传递给itemRef (最后一个参数)。然后你就会有一个指向你想要修改的密钥链的指针。
另外，你应该检查错误代码，看看你的add函数是否工作。
OSStatus result = SecKeychainAddInternetPassword(
NULL,
StrLength("myserver.com"),
"myserver.com",
0,
NULL,
StrLength(userString),
userString,
0,
nil,
0,
kSecProtocolTypeHTTPS,
kSecAuthenticationTypeHTMLForm,
passwordLength,
password,
NULL
);
if(result != noErr){
NSLog(@"Error AddPassword result=:%d", result );
}这是我的示例程序，代码与您提供的代码相同，并且运行良好。
int main(int argc, const char * argv[])
{
@autoreleasepool {
char *inputpassword = "topsecret";
UInt32 inputpassLength = strlen(inputpassword);
OSStatus status;
NSString *_username = @"account_name";
char *userString;
userString = (char *)[_username UTF8String];
status = SecKeychainAddInternetPassword(
NULL,
StrLength("myserver.com"),
"myserver.com",
0,
NULL,
StrLength(userString),
userString,
0,
nil,
0,
kSecProtocolTypeHTTPS,
kSecAuthenticationTypeHTMLForm,
inputpassLength,
inputpassword,
NULL
);
NSLog(@"Adding Status:%d", status);
UInt32 returnpasswordLength = 0;
char *passwordData;
status = SecKeychainFindInternetPassword(
NULL,
StrLength("myserver.com"),
"myserver.com",
0,
NULL,
StrLength(userString),
userString,
0,
nil,
0,
kSecProtocolTypeHTTPS,
kSecAuthenticationTypeHTMLForm,
&returnpasswordLength,
(void *)&passwordData,
NULL
);
NSLog(@"Retrieving status:%d", status);
NSLog(@"Password:%@", [[NSString alloc] initWithBytes:passwordData
length:returnpasswordLength
encoding:NSUTF8StringEncoding]);
}
return 0;
