Question

大家好我有一个阵列，我正在获取

等网站的链接

http://clickfrom.buy.com/default.asp?adid\u003d17379&sURL\u003dhttp%3A%2F%2Fwww.buy.com%2Fprod%2Fkimberly-clark-professional-kleenex-boutique-white-facial-tissue-2-ply%2Fq%2Floc%2F66357%2F211347223.html

我想要的只是获得主域名。 clickfrom.buy.com

主要网站地址。如何实现......

Answer 1

如果你有NSURL，你可以要求

[url host]

这应该与上面的“clickfrom.buy.com”相对应。

Answer 2

你可以用：

NSString *myUrl = @"http://clickfrom.buy.com/default.asp?adid\\u003d17379&sURL\\u003dhttp%3A%2F%2Fwww.buy.com%2Fprod%2Fkimberly-clark-professional-kleenex-boutique-white-facial-tissue-2-ply%2Fq%2Floc%2F66357%2F211347223.html";

NSURL *url = [NSURL URLWithString:myUrl];

NSLog(@"%@", [url host]);

修改

序列

\u003d
NSString中的
被解释为通用字符，因此必须引用我们的示例：

\\u003d

并且会导致错误： \ u003d不是有效的通用字符。仍然存在解析问题，因为反斜杠似乎是URI语法中的无效字符。它必须被百分比逃脱。

查看RFC 2396 / 2.4.3。排除的US-ASCII字符

... Other characters are excluded because gateways and other transport agents are known to sometimes modify such characters, or they are used as delimiters. unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`" Data corresponding to excluded characters must be escaped in order to be properly represented within a URI.

这样做

NSString *myUrl = [@"http://clickfrom.buy.com/default.asp?adid\\u003d17379&sURL\\u003dhttp%3A%2F%2Fwww.buy.com%2Fprod%2Fkimberly-clark-professional-kleenex-boutique-white-facial-tissue-2-ply%2Fq%2Floc%2F66357%2F211347223.html" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

应该让解析工作。

使用rangeOfString的{{1}}方法获取您的域的边界，然后使用NSString的{{1}}方法提取域文本。
