引言
知道OkHttp底层是通过Socket连接，发送网络请求，本篇文章就是模拟这种方式来发送网路请求
发送网络请求
测试http
1. 建立socket连接
public static void main(String[] args) {
try {
testHttp("http://localhost:3434/okhttp");
} catch (IOException e) {
e.printStackTrace();
}
}
private static void testHttp(String url) throws IOException {
OkHttpClient client = new OkHttpClient().newBuilder().build();
Request request = new Request.Builder().url(url).build();
System.out.println(request);
HttpUrl httpUrl = request.url;
System.out.println("httpUrl:" + httpUrl);
System.out.println("host:" + httpUrl.host());
System.out.println("port:" + httpUrl.port());
System.out.println("pathSegments:" + httpUrl.pathSegments());
Dns dns = client.dns;
System.out.println("dns:" + dns);
List<InetAddress> addresses = dns.lookup(httpUrl.host());
//[localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:
System.out.println("addresses:" + addresses);
SocketFactory socketFactory = client.socketFactory();
System.out.println("SocketFactory:" + socketFactory);
//建立安全连接的时候需要
SSLSocketFactory sslSocketFactory = null;
HostnameVerifier hostnameVerifier = null;
CertificatePinner certificatePinner = null;
if (httpUrl.isHttps()) {
sslSocketFactory = client.sslSocketFactory();
hostnameVerifier = client.hostnameVerifier();
certificatePinner = client.certificatePinner();
}
Authenticator authenticator = client.authenticator();
Proxy proxy = client.proxy();
List<Protocol> protocols = client.protocols;
System.out.println("DEFAULT_PROTOCOLS:" + protocols);
List<ConnectionSpec> connectionSpecs = client.connectionSpecs;
System.out.println("DEFAULT_CONNECTION_SPECS:" + connectionSpecs);
ProxySelector proxySelector = ProxySelector.getDefault();
System.out.println("ProxySelector:" + proxySelector);
//创建Address
Address address = new Address(httpUrl.host, httpUrl.port, dns, socketFactory,
sslSocketFactory, hostnameVerifier, certificatePinner, authenticator,
proxy, protocols, connectionSpecs, proxySelector);
//建立socket连接
Socket socket = socketFactory.createSocket();
//需要IPV4
InetAddress inetAddress = addresses.get(0);
//localhost/127.0.0.1
System.out.println(inetAddress);
//构建InetSocketAddress
InetSocketAddress inetSocketAddress = new InetSocketAddress(inetAddress, httpUrl.port);
//localhost/127.0.0.1:3434
System.out.println(inetSocketAddress);
//socket.connect(inetAddress, 1000);
socket.connect(inetSocketAddress);
System.out.println("socket:" + socket);
//获取输入输出流
OutputStream outputStream = socket.getOutputStream();
InputStream inputStream = socket.getInputStream();
}

当目前为止已经建立了连接，由于http是不安全的连接，不需要嵌套安全连接。
2. 发送请求
模拟发送http请求
String header = "GET http://localhost:3434/okhttp HTTP/1.1\r\n";
outputStream.write(header.getBytes());
//发送请求头
outputStream.write("Accept-Encoding: gzip\r\n".getBytes());
outputStream.write("Connection: keep-alive\r\n".getBytes());
outputStream.write("Host: localhost:3434\r\n".getBytes());
outputStream.write("User-Agent: DiyClient/zy\r\n".getBytes());
outputStream.write("\r\n".getBytes());
outputStream.flush();
3. 接受数据
//读取数据
byte[] data = new byte[1024];
System.out.println("read...");
int read = inputStream.read(data);
while (read != -1) {
System.out.println(new String(data));
read = inputStream.read(data);
}
HTTP/1.1 200 OK
Date: Fri, 09 Oct 2020 00:30:45 GMT
Content-Type: application/json; charset=UTF-8
author: zy
Connection: close
Server: Jetty(9.3.2.v20150730)
{"code":200,"msg":"OK","data":"GET from Server,Your Msg is :"}
测试post数据
确认请求行
POST http://localhost:3434/okhttp HTTP/1.1
Accept-Encoding: gzip
Connection: keep-alive
Content-Length: 22
Content-Type: application/json; charset=UTF-8
Host: localhost:3434
User-Agent: zy/test
{"name":"zy","age":18}
用java代码发送：
//发送请求行
String header = "POST http://localhost:3434/okhttp HTTP/1.1\r\n";
outputStream.write(header.getBytes());
//发送请求头
outputStream.write("Accept-Encoding: gzip\r\n".getBytes());
outputStream.write("Connection: keep-alive\r\n".getBytes());
outputStream.write("Host: localhost:3434\r\n".getBytes());
outputStream.write("Content-Length: 22\r\n".getBytes());
outputStream.write("Content-Type: application/json; charset=UTF-8\r\n".getBytes());
outputStream.write("User-Agent: DiyClient/zy\r\n".getBytes());
outputStream.write("\r\n".getBytes());
outputStream.write("{\"name\":\"zy\",\"age\":18}".getBytes());//发送内容
outputStream.write("\r\n".getBytes());
outputStream.flush();
结果如下：

发现返回来的参数都是乱码
原来在请求头中添加了Accept-Encoding字段，但是本地却没有编码处理，所以移除掉这个字段。
//outputStream.write("Accept-Encoding: gzip\r\n".getBytes());
把编码屏蔽掉，在测试一下。
