我正在获取以下格式的 HTML 内容。

wsse:BinarySecurityToken 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</wsse:BinarySecurityToken><

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:@"=<" 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。

有任何想法吗？提前致谢。

当您讨论您拥有NSString *token = @"<wsse:BinarySecurityToken>aHR0cCUzYSUyZiUyZnNjaGVtYWd0Sjk0JTNk</wsse:BinarySecurityToken>"; 的以及标签之间的标记时，您可以替换不需要的字符，例如 .

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

进而

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