Python划词翻译通过socket发送到Android端显示

 实现不难，原理python 通过socket与Android获取连接 

Python 作为Server端 ，Android作为Client 端接收Python发送过来的数据。Android需要知道Python server端的IP地址和的端口号 。 端口号可以在Python随意指定，不冲突就行。

Python设置热键，获取粘贴板的内容，即要翻译的单词。至于翻译有两种方式，第一种Python获取单词，将单词发送到Android端，由Android端请求翻译API。第二种，由Python获取单词，并且由Python请求API翻译，将单词和释义都发送到Android。本文采用后者，原因是，百度翻译API提供了Python请求的实例，可以说是傻瓜式操作了。

接下来上Python代码：

import socket
import keyboard

import pyperclip

import http.client
import hashlib
import urllib
import random
import json

# 先设置 热键
plist = []


def getData():
    print("触发事件")
    # ctrl c c 会触发两次事件取第二次 内容就是最新的粘贴板上的内容
    data = pyperclip.paste()
    plist.append(data)
    if len(plist) > 1:
        msg = plist[1]  #原始值
        try:
            appid = ''  # 填写你的appid
            secretKey = ''  # 填写你的密钥

            httpClient = None
            myurl = '/api/trans/vip/translate'

            fromLang = 'auto'  # 原文语种
            toLang = 'zh'  # 译文语种
            salt = random.randint(32768, 65536)
            q = msg
            sign = appid + q + str(salt) + secretKey
            sign = hashlib.md5(sign.encode()).hexdigest()
            myurl = myurl + '?appid=' + appid + '&q=' + urllib.parse.quote(
                q) + '&from=' + fromLang + '&to=' + toLang + '&salt=' + str(
                salt) + '&sign=' + sign
            httpClient = http.client.HTTPConnection('api.fanyi.baidu.com')
            httpClient.request('GET', myurl)

            # response是HTTPResponse对象
            response = httpClient.getresponse()
            result_all = response.read().decode("utf-8")
            result = json.loads(result_all)
            transfer = result.get("trans_result")[0].get("dst")
            print(transfer)   #翻译结果
            send_data =q+"+"+transfer






        except Exception as e:
            print(e)

        print("发送" + send_data + "成功")
        conn.send(send_data.encode())  # 把接收到数据原封不动的发送回去
        plist.clear()


# wait里也可以设置按键，说明当按到该键时结束

def getipaddrs(hostname):  # 只是为了显示IP，仅仅测试一下
    result = socket.getaddrinfo(hostname, None, 0, socket.SOCK_STREAM)
    return [x[4][0] for x in result]


host = ''  # 为空代表为本地host
hostname = socket.gethostname()
hostip = getipaddrs(hostname)
print('host ip', hostip)  # 应该显示为：127.0.1.1
port = 23411  # Arbitrary non-privileged port
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host, port))
s.listen(4)

while True:
    conn, addr = s.accept()
    print('Connected by', addr)
    data = conn.recv(1024)
    # 当我确认client 和我建立连接 我将数据发给client

    print("接收到Android 发送的数据为" + data.decode())

    keyboard.add_hotkey('ctrl+c', getData)

    if not data:
        break
    keyboard.wait()

    conn.close()

其中融合了百度翻译API提供的例子
