先看看效果

在这里插入图片描述
可以选择字体、颜色，这里我们用默认的看看的效果。

啊这，一笔学不来，算了，咱们敲代码吧…

1.需要用到的模块

import requests
from PIL import Image
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5 import QtWidgets, QtGui

#兄弟们学习python，有时候不知道怎么学，从哪里开始学。掌握了基本的一些语法或者做了两个案例后，不知道下一步怎么走，不知道如何去学习更加高深的知识。
#那么对于这些大兄弟们，我准备了大量的免费视频教程，PDF电子书籍，以及视频源的源代码！
#还会有大佬解答！
#都在这个群里了 924040232
#欢迎加入，一起讨论 一起学习！

2.窗口名字/图标/大小/布局

self.setFixedSize(600, 500)
self.setWindowTitle('嗨学编程—艺术签名生成器')
self.setWindowIcon(QIcon('resource/icon/icon.jpg'))
self.grid = QGridLayout()

3.必要组件的定义

self.show_label = QLabel()
self.show_label.setScaledContents(True)
self.show_label.setMaximumSize(600, 400)
self.show_image = Image.open('resource/image/ori.jpg').convert('RGB')
self.updateimage()
self.show_image_ext = 'jpg'
self.name_label = QLabel('输入您的姓名:')
self.font_label = QLabel('艺术签名字体:')
self.color_label = QLabel('艺术签名颜色:')

4.输入框

self.name_edit = QLineEdit()
self.name_edit.setText('签名生成器')

5.保存/生成按钮

self.generate_button = QPushButton('生成艺术签名')
self.save_button = QPushButton('保存艺术签名')

6.下拉框

self.font_combobox = QComboBox()
for item in ['一笔艺术签', '连笔商务签', '一笔商务签', '真人手写', '暴躁字']:
    self.font_combobox.addItem(item)
self.color_combobox = QComboBox()
for item in ['Black', 'Blue', 'Red', 'Green', 'Yellow', 
             'Pink', 'DeepSkyBlue', 'Cyan', 'Orange', 'Seashell']:
    self.color_combobox.addItem(item)

7.组件布局

self.grid.addWidget(self.show_label, 0, 0, 5, 5)
self.grid.addWidget(self.name_label, 5, 0, 1, 1)
self.grid.addWidget(self.name_edit, 5, 1, 1, 4)
self.grid.addWidget(self.font_label, 6, 0, 1, 1)
self.grid.addWidget(self.font_combobox, 6, 1, 1, 4)
self.grid.addWidget(self.color_label, 7, 0, 1, 1)
self.grid.addWidget(self.color_combobox, 7, 1, 1, 4)
self.grid.addWidget(self.generate_button, 8, 3, 1, 1)
self.grid.addWidget(self.save_button, 8, 4, 1, 1)
self.setLayout(self.grid)

8.事件绑定

self.generate_button.clicked.connect(self.generate)
self.save_button.clicked.connect(self.save)

9.生成签名

def generate(self):
    font2ids_dict = {
                        '一笔艺术签': ['901', '15'],
                        '连笔商务签': ['904', '15'],
                        '一笔商务签': ['905', '14'],
                        '真人手写': ['343', '14'],
                        '卡通趣圆字': ['397', '14'],
                        '暴躁字': ['380', '14']
                }
    color2ids_dict = {
                        'Black': ['#000000', '#FFFFFF'],
                        'Blue': ['#0000FF', '#FFFFFF'],
                        'Red': ['#FF0000', '#FFFFFF'],
                        'Green': ['#00FF00', '#FFFFFF'],
                        'Yellow': ['#FFFF00', '#FFFFFF'],
                        'Pink': ['#FFC0CB', '#FFFFFF'],
                        'DeepSkyBlue': ['#00BFFF', '#FFFFFF'],
                        'Cyan': ['#00FFFF', '#FFFFFF'],
                        'Orange': ['#FFA500', '#FFFFFF'],
                        'Seashell': ['#FFF5EE', '#FFFFFF']
                    }
    url = 'http://www.jiqie.com/a/re14.php'
    headers = {
                'Referer': 'http://www.jiqie.com/a/14.htm',
                'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.129 Safari/537.36',
                'Host': 'www.jiqie.com',
                'Origin': 'http://www.jiqie.com'
            }
    ids_0 = font2ids_dict[self.font_combobox.currentText()]
    ids_1 = color2ids_dict[self.color_combobox.currentText()]
    data = {
                'id': self.name_edit.text(),
                'zhenbi': '20191123',
                'id1': ids_0[0],
                'id2': ids_0[1],
                'id3': ids_1[0],
                'id5': ids_1[1]
            }
    res = requests.post(url, headers=headers, data=data)
    image_url = re.findall(r'src="(.*?)"', res.text)[0]
    self.show_image_ext = image_url.split('.')[-1].split('?')[0]
    res = requests.get(image_url)
    fp = open('tmp.%s' % self.show_image_ext, 'wb')
    fp.write(res.content)
    fp.close()
    self.show_image = Image.open('tmp.%s' % self.show_image_ext).convert('RGB')
    self.updateimage()
    os.remove('tmp.%s' % self.show_image_ext)

10.更新界面上的图片

def updateimage(self):
    if self.show_image is None:
        return
    fp = io.BytesIO()
    self.show_image.save(fp, 'JPEG')
    qtimage = QtGui.QImage()
    qtimage.loadFromData(fp.getvalue(), 'JPEG')
    qtimage_pixmap = QtGui.QPixmap.fromImage(qtimage)
    self.show_label.setPixmap(qtimage_pixmap)

11.签名保存

def save(self):
    if self.show_image is None:
        return
    filename = QFileDialog.getSaveFileName(self, '保存', './sign.%s' % self.show_image_ext, '所有文件(*)')
    if filename[0]:
        self.show_image.save(filename[0])
        QDialog().show()

12.run

if __name__ == '__main__':
    app = QApplication(sys.argv)
    gui = ArtSignGenerator()
    gui.show()
    sys.exit(app.exec_())

只是粗糙的实现了这些功能，大家可以换着花样玩玩，不喜勿喷。
