public class SocketTest {
public static void main(String[] args) throws IOException {
Socket socket = new Socket("localhost", 10050);
// 創(chuàng)建請(qǐng)求流
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(socket.getOutputStream(), StandardCharsets.UTF_8);
// 寫入地址等信息
outputStreamWriter.write("GET /api/cmscore/template/config/info?configId=5 HTTP/1.1\r\n");

總結(jié)
其實(shí)http協(xié)議汹想，就是特定格式的網(wǎng)絡(luò)數(shù)據(jù)包追葡，我們只需要根據(jù)不同的場(chǎng)景拼接出特定的格式审轮，就可以完成一次http請(qǐng)求肥哎。
不過(guò)現(xiàn)在已經(jīng)有很多框架，底層實(shí)現(xiàn)了對(duì)http請(qǐng)求的解析和封裝疾渣，我們無(wú)需再關(guān)注篡诽，但是在不依賴框架的情況下，還是需要知道其中原理榴捡。
