import requests
import json
import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtWidgets import QApplication, QMainWindow,QPushButton , QTextEdit, QWidget

class Apd(QMainWindow):
    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        ###设置主窗口的标题###
        self.setWindowTitle = "text.button"
        ###设置窗口的尺寸###
        self.resize(600, 550)
        ##设置垂直布局
        layout = QVBoxLayout()
        self.setLayout(layout)
        ###设置状态栏###
        self.status = self.statusBar()
        self.status.showMessage("显示各种各样的股票信息", 5000)
        ##创建文本框用于显示
        font = QtGui.QFont()
        font.setFamily("微软雅黑")
        font.setPointSize(10)
        self.text_browser = QTextBrowser(self)
        self.text_browser.move(160, 30)
        self.text_browser.resize(400,400)
        ##按钮
        button = QPushButton("测试", self)
        button.move(20, 120)
        button.setToolTip("这是爬取股票五分钟涨幅相关股票")
        button.clicked.connect(self.Brower)
        ##显示
        self.show()

    def Brower(self):
        self.text_browser.setText(self.stockA)

    def stockA(self):

            html = requests.get(url,headers=headers).text.encode()
            data = json.loads(html)
            news = data['list']
            for n in news:
            ##股票名称##
                data1 = n['NAME']
            ##股票代码##
                data2 = n['SYMBOL']
            ##股票价格##
                data3 = str(n['PRICE'])
            ##涨跌幅##
                data4 = str(n['UPDOWN'])
                dat = {"名称":data1,"代码":data2,"价格":data3,"涨跌":data4}
                print(dat)
                 


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

报如下错误，不是很理解，百度上也没有相关资料，qwq

    self.text_browser.setText(self.stockA)    
TypeError: setText(self, str): argument 1 has 
unexpected type 'method'

Answer 1

setText()明显要接受一个str参数, 你直接传了一个函数能对吗...而且这stockA()也没有返回值啊, 光把爬到的数据打印出来, 没有保存
stockA()返回data, 然后setText(str(stockA()))
