IIRC，斜杠应该在URL的查询部分正确解释。你测试看看它仍然工作没有编码的斜杠？否则，请执行以下操作：

IIRC, slashes should be interpreted properly when they're in the query part of a URL. Did you test to see if it still works without encoded slashses? Otherwise, do something like:

if ([args isKindOfClass:[NSDictionary class]]) {
        for (NSString *key in [args allKeys]) {
            NSString *value = [(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault, (CFStringRef)[args objectForKey:key], NULL, CFSTR("/?&:=#"), kCFStringEncodingUTF8) autorelease];
            [url appendString:[NSString stringWithFormat:@"&%@=%@", key, value]];
            [value release];
        }
}

return url;

注意CFURLCreateStringByAddingPercentEscapes的第4个参数的值。

Note the value of the 4th argument to CFURLCreateStringByAddingPercentEscapes.
