PySide6 - HTTP接口测试器

参考链接：https://blog.csdn.net/a597934448/article/details/118110839

界面设计

打开 Qt designer 设计如下界面，保存为 httpclient.ui

代码实现

• requests库的使用
• QTableWidget 类的方法使用currentRow()、insertRow、removeRow
• QTextEdit类的 append() 方法

这里主要借鉴了参考文章的请求头和响应头的打印处理方法，有点意思，我还以为requests真有现成的属性呢

from PySide.QtWidgets import QApplication
from PySide.QtUiTools import QUiLoader
from PySide.QtCore import QObject
from PySide.QtGui import  QIcon

class HttpClient(QObject):
    def __init__(self):
        QObject.__init__(self)
        # 从 UI 定义中动态 创建一个相应的窗口对象
        self.ui = QUiLoader().load('httpclient.ui')

        # 给 boxMethod 添加选项 GET POST PUT DELETE
        self.ui.boxMethod.addItems(['GET', 'POST', 'PUT', 'DELETE'])

        # 让 表格控件宽度随着父窗口的缩放自动缩放
        self.ui.headersTable.horizontalHeader().setStretchLastSection(True)
        # 设定第1列的宽度为 180像素
        self.ui.headersTable.setColumnWidth(0, 180)

		# 槽函数
        self.ui.buttonSend.clicked.connect(self.sendRequest)
        self.ui.buttonAddHeader.clicked.connect(self.addOneHeader)
        self.ui.buttonDelHeader.clicked.connect(self.delOneHeader)


    def addOneHeader(self):

        # rowCount = self.ui.headersTable.rowCount()
        # 要插入的行始终是当前行 的下一行
        addRowNumber = self.ui.headersTable.currentRow() + 1
        self.ui.headersTable.insertRow(addRowNumber)
