我正在获取以下格式的 HTML 内容。

wsse:BinarySecurityToken wsu:Id=&quot;uuid:07747f2a-4be4-48fa-9654-5e12235f6040&quot; ValueType=&quot;http://schemas.xmlsoap.org/ws/2009/11/swt-token-profile-1.0&quot; EncodingType=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary&quot; xmlns:wsu=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd&quot; xmlns:wsse=&quot;http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd&quot;>
aHR0cCUzYSUyZiUyZnNjaGVtYXMubWNk&lt;/wsse:BinarySecurityToken>&lt;

在下面的代码中，我得到 wsu:Id="uuid:07747f2a-4be4-48fa-9654-5e12235f6040" ValueType="http://schemas.xmlsoap.org/ws/2009/11/swt-token-profile-1.0" EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> aHR0cCUzYSUyZiUyZnNjaGVtYXMubWNk

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
if(_data)
{
    NSString* content = [[NSString alloc] initWithData:_data
                                              encoding:NSUTF8StringEncoding];
    NSLog(@"Content  :%@",content);

    NSRange divRange = [content rangeOfString:@"wsse:BinarySecurityToken" options:NSCaseInsensitiveSearch];

    if (divRange.location != NSNotFound)
    {
        NSRange endDivRange;

        endDivRange.location = divRange.length + divRange.location;
        endDivRange.length   = [content length] - endDivRange.location;
        endDivRange = [content rangeOfString:@"=&lt;" options:NSCaseInsensitiveSearch range:endDivRange];

        if (endDivRange.location != NSNotFound)
        {
            divRange.location += divRange.length;
            divRange.length  = endDivRange.location - divRange.location;


            NSLog(@"BinarySecurityToken : %@",[content substringWithRange:divRange]);
        }
    }

    [webView loadHTMLString:content baseURL:_url];

}

}

我希望输出为 aHR0cCUzYSUyZiUyZnNjaGVtYXMubWNk。

有什么想法吗？提前致谢。

【问题讨论】：

昨天你接受了同样的答案现在是什么？ stackoverflow.com/questions/16566129/…
它有一些属性，也用令牌打印。你能帮我删除它吗？
使用我的方法并使用NSString *token = [self stringBetweenString:@"sse:BinarySecurityToken>" andString:@"</wsse:BinarySecurityToken>"];调用它
stringBetweenString 不起作用，无论如何，非常感谢 Bunty
对你这个年轻人有用吗？

【解决方案1】：

当你讨论你有NSString *token = @"<wsse:BinarySecurityToken>aHR0cCUzYSUyZiUyZnNjaGVtYWd0Sjk0JTNk</wsse:BinarySecurityToken>"; 以及标签之间的标记然后您可以替换不需要的字符，例如 .

NSString *str = [token stringByReplacingOccurrencesOfString:@"<wsse:BinarySecurityToken>" withString:@""];;

然后

NSString *correctToken = [str stringByReplacingOccurrencesOfString:@"</wsse:BinarySecurityToken>" withString:@""];;
