Python制作Soap通信测试软件

辛苦堆砌，转载请注明出处，谢谢！

最进工作中涉及Android端和服务器端通过Soap进行通信，就不可避免的需要对接Soap服务，抽空用Python做了一个小工具，用来实现Soap服务的测试。该小工具主要使用了PyQt5和suds-py3两个模块，PyQt5是Qt的Python版图形界面库，之前本人用过Qt C++的库，所以对Qt有些基础，所以选择了PyQt5；suds-py3则是针对Python3.x的Soap客户端。使用前去要安装对应的模块，首先是PyQt5

pip install pyqt5

然后是suds-py3

pip install suds-py3

安装完成后，为了演示示例，我们创建自己的Soap服务，就是之前ksoap2介绍中使用的服务

import logging  logging.basicConfig(level=logging.DEBUG)    from spyne import Application, rpc, ServiceBase, Unicode    from spyne import Iterable    from spyne.protocol.soap import Soap11    from spyne.server.wsgi import WsgiApplication    class HelloWorldService(ServiceBase):      @rpc(Unicode, _returns=Unicode)      def say_hello(ctx, name):        if name:            return 'Hello, %s' % name        else:            return 'Hello'  application = Application([HelloWorldService],      tns='http://spyne.examples.hello/',      in_protocol=Soap11(),      out_protocol=Soap11())    if __name__ == '__main__':      from wsgiref.simple_server import make_server        wsgi_app = WsgiApplication(application)      server = make_server('0.0.0.0', 8000, wsgi_app)      server.serve_forever()

下面是我们的主角，实际上大部分代码是界面部分的，soap通信使用的代码不多，Soap参数使用Python字典的方式输入，另外由于这是自己使用的小工具，网络请求时没有启动线程，实际中，如果为了用户体验好一些，可以启动线程进行网络通信，首先是界面，我们的Dialog，web_service_dialog.py

from PyQt5.QtWidgets import QDialog, QLabel, QLineEdit, QTextEdit, QPushButton, QVBoxLayout, QHBoxLayout, QGridLayout, \    QMessageBoxfrom PyQt5.QtCore import Qt, pyqtSignal, QObjectfrom suds.client import Clientfrom suds import MethodNotFoundfrom suds.transport import TransportErrorimport jsonfrom global_params import DEFAULT_WSDLclass WebServiceDialog(QDialog):    class Signals(QObject):        request_complete = pyqtSignal(str)    def __init__(self, parent=None):        super(WebServiceDialog, self).__init__(parent)        wsdl_label = QLabel('WSDL:', self)        self.wsdlLineEdit = QLineEdit(self)        self.wsdlLineEdit.setText(DEFAULT_WSDL)        method_label = QLabel('方法:', self)        self.methodLineEdit = QLineEdit(self)        param_label = QLabel('参数字典:', self)        self.paramTextEdit = QTextEdit(self)        self.paramTextEdit.setFixedHeight(200)        response_label = QLabel('响应', self)        self.responseTextEdit = QTextEdit(self)        self.responseTextEdit.setFixedHeight(200)        self.responseTextEdit.setReadOnly(True)        form_layout = QGridLayout()        form_layout.addWidget(wsdl_label, 0, 0, 1, 1)        form_layout.addWidget(self.wsdlLineEdit, 0, 1, 1, 1)        form_layout.addWidget(method_label, 1, 0, 1, 1)        form_layout.addWidget(self.methodLineEdit, 1, 1, 1, 1)        form_layout.addWidget(param_label, 2, 0, 1, 1)        form_layout.addWidget(self.paramTextEdit, 2, 1, 1, 1)        form_layout.addWidget(response_label, 3, 0, 1, 1)        form_layout.addWidget(self.responseTextEdit, 3, 1, 1, 1)        self.okButton = QPushButton('确定', self)        self.cancelButton = QPushButton('取消', self)        button_layout = QHBoxLayout()        button_layout.addStretch()        button_layout.addWidget(self.okButton)        button_layout.addWidget(self.cancelButton)        button_layout.addStretch()        main_layout = QVBoxLayout()        main_layout.addLayout(form_layout)        main_layout.addLayout(button_layout)        self.okButton.clicked.connect(self.send_request)        self.cancelButton.clicked.connect(self.reject)        self.signal = self.Signals()        self.signal.request_complete.connect(self.request_complete)        self.setLayout(main_layout)        self.setWindowTitle('Soap调用测试')        self.setWindowFlags(Qt.WindowCloseButtonHint)        self.setMinimumWidth(500)        self.setFixedHeight(550)    def request_complete(self, ret):        self.responseTextEdit.setText(ret)    def send_request(self):        try:            client = Client(self.wsdlLineEdit.text())        except ValueError:            QMessageBox.information(self, "错误", "wsdl错误", QMessageBox.No)            return        params_str = self.paramTextEdit.toPlainText()        if params_str:            try:                params = eval(params_str)                if not isinstance(params, dict):                    raise NameError            except NameError:                QMessageBox.information(self, "错误", "参数格式错误，请输入字典", QMessageBox.No)                return        else:            params = {}        try:            ret = client.service.__getattr__(self.methodLineEdit.text())(**params)            self.signal.request_complete.emit(ret)        except MethodNotFound:            QMessageBox.information(self, "错误", "没有该方法", QMessageBox.No)            return        except TransportError:            QMessageBox.information(self, "错误", "请求错误", QMessageBox.No)            return

为了方便，我定义了一个DEFAULT_WSDL，用来初始显示，定义在global_params.py

DEFAULT_WSDL = r'http://192.168.6.27:8000/?wsdl'

然后是我们的主程序main.py

from PyQt5.Qt import QApplicationfrom web_service_dialog import WebServiceDialogimport sysif __name__ == '__main__':    app = QApplication(sys.argv)    web_service_dialog = WebServiceDialog()    web_service_dialog.show()    sys.exit(app.exec_())

运行并访问测试服务，如图所示

感兴趣的尝试一下，这里仅仅方便我的使用，如果大家有其他需求，可以在此基础上改进，比如可以添加namespace和上传文件等。
