深入理解 Web 协议（二）：系统了解 DNS 和 WebSocket

阅读更多关于深入理解 Web 协议（二）：系统了解 DNS 和 WebSocket

本文转载自 “Vivo 互联网技术”，已获授权。本文系统性的讲述了 DNS 协议与 WebSocket 协议的重要细节。一、DNS 1、Linux dig命令我们首先通过 Linux 下的dig命令来了解一下 DNS 是怎么做域名解析的。我们首先输入命令： dig www .baidu .com 看下标注的红框，从左到右依次代表：域名的名称也就是服务器名称网络类型， DNS 协议在设计的时候考虑到了其他网络类型，但是目前位置这个值还是写死的IN 你就理解成是互联网就可以了。这个值一般不变标识域名对应何种类型的地址，A 就代表ip的地址。这里可能有人会问了，这个域名的后面为啥还有个“.”？我们输入的明明是 www.baidu.com 不是 www.baidu.com. 啊。这里要提一下：末尾的 . 代表的就是根域名，每个域名都有根域名，所以通常我们会省略它。根域名的下一级叫顶级域名，比如我们熟知的.com与.net。再下一级就是次级域名了，比如例子中的.baidu。这个次级域名只要你有钱是可以随便注册的。最后这个 www ，这个代表三级域名。一般是用户在自己的域里面为服务器分配的名称。用户可以随便分他。所以可以看出来这里的域名是分级别的。能弄明白这点就能搞清楚为什么DNS的查询过程是分级查询了。我们可以利用dig

问题 I am trying to call and IMDb API 2 times, the first time it calls and gets the ID for that movie/show and the second time it uses that ID to get all the information about that movie/show, I also need that ID for another part of the app so that is why I am doing it this way. The problem is that the second call isn't waiting for the first call to be done. I think this is why the variables aren't updated when I am trying to use them. This is my onCreate method where all this is happening, I took

How to get more than one Set-Cookie header from response using Retrofit/OkHttpClient?

阅读更多关于 How to get more than one Set-Cookie header from response using Retrofit/OkHttpClient?

问题 I'm trying to make an authentication call using Retrofit/OkHttpClient on Android. The server responds a 302 with two Set-Cookie headers and okHttp handles redirection. I found some tips to get those cookies using cookieManager. But it seems cookieManager reads only one Set-Cookie header. I have this in server response headers: Set-Cookie:first=1 Set-Cookie:second=2 This is my cookieManager part: private static CookieManager cookieManager; (...) OkHttpClient okHttpClient = new OkHttpClient();
