NSURL组成部分详解

手思中有这么一段代码，初看下，让人摸不着头脑

//功能：UIWebView响应长按事件
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    if ([request URL].query){
        NSArray *array = [[request URL].query componentsSeparatedByString:@"&"];
        if (array.count)
        {
            for (int i = 0; i<array.count; i++) {
                NSString *str = [array objectAtIndex:i];
                NSArray *tArray = [str componentsSeparatedByString:@"="];
                DLog(@"params = %@",tArray);
                if (tArray.count>1){
                    for (int j = 0; j<tArray.count; j++) {
                        if (j==0){
                            if ([[tArray objectAtIndex:j]isEqualToString:@"id"]){
                                NSString   *idString = [tArray objectAtIndex:j+1];
                                NSLog(@"idString====%@",idString);
                            }
                        }
                    }
                }
                
            }
            
        }
    }
}

是不是，这是什么鬼。。。？

 

完整Url是这样的：http://183.6.151.51:8082/gwapi/news/detail?id=2776&uid=#top

[request URL].query  即为 id=2776&uid=

打印下idString为2776

之所以这样是为了获取id号，重新请求新数据
