### 首先展示一下最终的实现结果：[源代码下载][Link 1] ###

### 这里调用的是百度的翻译接口，我们通过访问[百度翻译][Link 2] 可以获得对应的url 和请求数据。。 ###

**第一步：** 我们打开百度翻译的网址，在翻译这边随便输入一个中文，可以发现下面那个请求包。。然后打开，会发现对应的url 和请求数据。等会我们模拟浏览器进行发送请求。。然后获取翻译的内容。

**  第二步：**我们先简单做一个不带界面的翻译代码

做了两个函数，一个是中文翻译为英文（函数translate()），一个是英文翻译为中文(函数translate1())。  url就是我们上面观察得到的url, 前面的v2版本号，我们在请求的url中去掉了。。接下来是data，这就是请求数据。。word就是我们带翻译的文本。最后会返回一个json格式的数据。。然后将数据提取出来即可。。

import requests
    
    def translate(word):
        url = 'https://fanyi.baidu.com/transapi'
        data = {
            'from': 'zh',
            'to': 'en',
            'query': word,
            'transtype': 'realtime',
            'simple_means_flag': '3',
            'sign': '325815.7046',
            'token': '9b1b599bf1303d7d525833a9e17579bb'
        }
        response = requests.post(url, data=data).json()   # 将获取的数据转换为json格式
        print(response['data'][0]['result'][0][1])
    
    
    def translate2(word):
        url = 'https://fanyi.baidu.com/transapi'
        data = {
            'from': 'en',
            'to': 'zh',
            'query': word,
            'transtype': 'realtime',
            'simple_means_flag': '3',
            'sign': '325815.7046',
            'token': '9b1b599bf1303d7d525833a9e17579bb'
        }
        response = requests.post(url, data=data).json()   # 将获取的数据转换为json格式
        print(response['data'][0]['result'][0][1])
    
    
    if __name__ == '__main__':
        sign = input("你想进行的是中翻英还是英翻中(中翻英按1，英翻中按2):")
        if sign == '1':
            word = input("请输入要翻译的中文:")
            translate(word)
        elif sign == '2':
            word = input("请输入要翻译的英文:")
            translate2(word)
        else:
            print("滚，你输入错了！！！")

输出结果展示：

**第三步：**我们借用PyQt设置一个界面。然后设置两个按钮，将这两个翻译函数绑定到按钮上即可。。

①：设置界面，通过QtDesign。。然后转换为下面的python代码

# -*- coding: utf-8 -*-
    
    # Form implementation generated from reading ui file 'Translate.ui'
    #

    from PyQt5 import QtCore, QtGui, QtWidgets
    
    class Ui_MainWindow(object):
        def setupUi(self, MainWindow):
            MainWindow.setObjectName("MainWindow")
            MainWindow.resize(800, 601)
            self.centralwidget = QtWidgets.QWidget(MainWindow)
            self.centralwidget.setObjectName("centralwidget")
            self.zh2en = QtWidgets.QPushButton(self.centralwidget)
            self.zh2en.setGeometry(QtCore.QRect(220, 470, 81, 61))
            font = QtGui.QFont()
            font.setFamily("Arial")
            font.setBold(False)
            font.setWeight(50)
            self.zh2en.setFont(font)
            self.zh2en.setObjectName("zh2en")
            self.en2zh = QtWidgets.QPushButton(self.centralwidget)
            self.en2zh.setGeometry(QtCore.QRect(360, 470, 81, 61))
            self.en2zh.setObjectName("en2zh")
            self.clearBtn = QtWidgets.QPushButton(self.centralwidget)
            self.clearBtn.setGeometry(QtCore.QRect(490, 470, 91, 61))
            self.clearBtn.setObjectName("clearBtn")
            self.label = QtWidgets.QLabel(self.centralwidget)
            self.label.setGeometry(QtCore.QRect(310, 40, 161, 31))
            font = QtGui.QFont()
            font.setFamily("楷体")
            font.setPointSize(26)
            self.label.setFont(font)
            self.label.setObjectName("label")
            self.textEdit1 = QtWidgets.QTextEdit(self.centralwidget)
            self.textEdit1.setGeometry(QtCore.QRect(90, 120, 271, 301))
            self.textEdit1.setObjectName("textEdit1")
            self.textEdit2 = QtWidgets.QTextEdit(self.centralwidget)
            self.textEdit2.setGeometry(QtCore.QRect(449, 121, 271, 301))
            self.textEdit2.setObjectName("textEdit2")
            MainWindow.setCentralWidget(self.centralwidget)
            self.menubar = QtWidgets.QMenuBar(MainWindow)
            self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 23))
            self.menubar.setObjectName("menubar")
            MainWindow.setMenuBar(self.menubar)
            self.statusbar = QtWidgets.QStatusBar(MainWindow)
            self.statusbar.setObjectName("statusbar")
            MainWindow.setStatusBar(self.statusbar)
    
            self.retranslateUi(MainWindow)
            QtCore.QMetaObject.connectSlotsByName(MainWindow)
    
        def retranslateUi(self, MainWindow):
            _translate = QtCore.QCoreApplication.translate
            MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
            self.zh2en.setText(_translate("MainWindow", "中文翻译英文"))
            self.en2zh.setText(_translate("MainWindow", "英文翻译中文"))
            self.clearBtn.setText(_translate("MainWindow", "清空"))
            self.label.setText(_translate("MainWindow", "小狗翻译"))
            self.textEdit1.setHtml(_translate("MainWindow", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n"
    "<html><head><meta name=\"qrichtext\" content=\"1\" /><style type=\"text/css\">\n"
    "p, li { white-space: pre-wrap; }\n"
    "</style></head><body style=\" font-family:\'SimSun\'; font-size:9pt; font-weight:400; font-style:normal;\">\n"
    "<p style=\" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;\">请输入翻译的内容</p>\n"
    "<p style=\"-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;\"><br /></p></body></html>"))
            self.textEdit2.setHtml(_translate("MainWindow", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n"
    "<html><head><meta name=\"qrichtext\" content=\"1\" /><style type=\"text/css\">\n"
    "p, li { white-space: pre-wrap; }\n"
    "</style></head><body style=\" font-family:\'SimSun\'; font-size:9pt; font-weight:400; font-style:normal;\">\n"
    "<p style=\" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;\">输出结果</p></body></html>"))

②：接下来在同级目录下建立一个python文件callTranslate.py （这个名字是随便起的）实现调用界面，并给按钮绑定槽函数。。实现如下：

from PyQt5.QtGui import *
    from PyQt5.QtWidgets import *
    from PyQt5.QtCore import *
    import requests
    import sys
    from Translate import Ui_MainWindow
    
    
    class Win(QMainWindow, Ui_MainWindow):
        def __init__(self, parent=None):
            super(Win, self).__init__(parent)
            self.setupUi(self)
    
            self.zh2en.clicked.connect(self.zh2enfun)
            self.en2zh.clicked.connect(self.en2zhfun)
            self.clearBtn.clicked.connect(self.clearinfo)
    
        def zh2enfun(self):
            '''中文翻译为英文'''
            word = self.textEdit1.toPlainText()
            url = 'https://fanyi.baidu.com/transapi'
            data = {
                'from': 'zh',
                'to': 'en',
                'query': word,
                'transtype': 'realtime',
                'simple_means_flag': '3',
                'sign': '325815.7046',
                'token': '9b1b599bf1303d7d525833a9e17579bb'
            }
            response = requests.post(url, data=data).json()  # 将获取的数据转换为json格式
            info = response['data'][0]['result'][0][1]
            self.textEdit2.setText(info)
    
        def en2zhfun(self):
            '''英文翻译为中文'''
            word = self.textEdit1.toPlainText()
            url = 'https://fanyi.baidu.com/transapi'
            data = {
                'from': 'en',
                'to': 'zh',
                'query': word,
                'transtype': 'realtime',
                'simple_means_flag': '3',
                'sign': '325815.7046',
                'token': '9b1b599bf1303d7d525833a9e17579bb'
            }
            response = requests.post(url, data=data).json()  # 将获取的数据转换为json格式
            info = response['data'][0]['result'][0][1]
            self.textEdit2.setText(info)
    
        def clearinfo(self):
            self.textEdit1.clear()
            self.textEdit2.clear()
    
    if __name__ == "__main__":
        app = QApplication(sys.argv)
        win = Win()
        win.setObjectName("MainWindow")  # 为主窗口设置对象名 为了在下面设置背景颜色
        win.setStyleSheet("#MainWindow{border-image:url(./data/background.jpg);}")
        win.show()
        sys.exit(app.exec_())

最后执行callTranslate.py  输出结果：
