用python写一个带界面的接口测试工具

好的，下面是一个使用Python和PyQt5库编写的简单的接口测试工具GUI示例代码：

import sys
import requests
from PyQt5.QtWidgets import QApplication, QMainWindow, QWidget, QLabel, QLineEdit, QTextEdit, QPushButton, QVBoxLayout, QHBoxLayout


class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()
        self.init_ui()

    def init_ui(self):
        # 创建主窗口部件
        widget = QWidget()
        self.setCentralWidget(widget)

        # 创建窗口部件的子部件
        self.url_label = QLabel('URL:')
        self.url_edit = QLineEdit()
        self.method_label = QLabel('Method:')
        self.method_edit = QLineEdit()
        self.headers_label = QLabel('Headers:')
        self.headers_edit = QTextEdit()
        self.params_label = QLabel('Params:')
        self.params_edit = QTextEdit()
        self.body_label = QLabel('Body:')
        self.body_edit = QTextEdit()
        self.response_label = QLabel('Response:')
        self.response_edit = QTextEdit()
        self.send_button = QPushButton('Send')

        # 创建布局
        main_layout = QVBoxLayout()
        form_layout = QHBoxLayout()
        form_layout.addWidget(self.url_label)
        form_layout.addWidget(self.url_edit)
        form_layout.addWidget(self.method_label)
        form_layout.addWidget(self.method_edit)
        main_layout.addLayout(form_layout)
        main_layout.addWidget(self.headers_label)
        main_layout.addWidget(self.headers_edit)
        main_layout.addWidget(self.params_label)
        main_layout.addWidget(self.params_edit)
        main_layout.addWidget(self.body_label)
        main_layout.addWidget(self.body_edit)
        main_layout.addWidget(self.response_label)
        main_layout.addWidget(self.response_edit)
        main_layout.addWidget(self.send_button)

        # 设置布局
        widget.setLayout(main_layout)

        # 设置窗口属性
        self.setGeometry(300, 300, 800, 600)
        self.setWindowTitle('API Test Tool')

        # 绑定事件
        self.send_button.clicked.connect(self.send_request)

    def send_request(self):
        url = self.url_edit.text()
        method = self.method_edit.text()
        headers = eval(self.headers_edit.toPlainText())
        params = eval(self.params_edit.toPlainText())
        body = self.body_edit.toPlainText()

        if method == 'GET':
            response = requests.get(url, headers=headers, params=params)
        elif method == 'POST':
            response = requests.post(url, headers=headers, params=params, json=eval(body))
        else:
            return

        self.response_edit.setText(response.text)


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

这个工具界面比较简单，包括了URL、Method、Headers、Params、Body和Response等几个常见的接口测试参数，用户可以在界面上填写参数，然后点击Send按钮，程序会发送请求并显示响应结果。需要注意的是，这个工具只是一个示例，实际使用时需要根据具体的需求进行修改和扩展。
