Question

import logging
import sys
import suds
from PyQt4 import QtCore, QtGui, QtNetwork
from service import Ui_Form
from suds.wsse import *

logging.basicConfig(level=logging.DEBUG)
logging.getLogger("suds.client").setLevel(logging.CRITICAL)
url = "http://xxxxxxxxx:xxxx/services/FireScopeConfigurationWebService/v1?wsdl"
token = UsernameToken("xxx", "xxxxx")
security = Security()
security.tokens.append(token)

client = suds.client.Client(url)
client.set_options(wsse = security)

class StartQT4(QtGui.QMainWindow):
    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_Form()
        self.ui.setupUi(self)
        QtCore.QObject.connect(self.ui.createButton,QtCore.SIGNAL("clicked()"), self.create_srv)
        ciEditLine = QtGui.QLineEdit()        #variable 1
        str(ciEditLine.displayText())
        monitorEditLine = QtGui.QLineEdit()   #variable 2
        str(monitorEditLine.displayText())
        bolEditLine = QtGui.QLineEdit()       #variable 3
        str(bolEditLine.displayText())
        ipEditLine = QtGui.QLineEdit()        #variable 4
        str(ipEditLine.displayText())

    def create_srv(self):
        try:
                response = client.service.createConfigurationItem(ciEditLine, monitorEditLine, bolEditLine, ipEditLine)
                print response
        except WebFault, e:
                print e


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    myapp = StartQT4()
    myapp.show()
    sys.exit(app.exec_())

我正在尝试从我的GUI中的4个LineEdit框中获取用户输入，并将它们用作我的函数中的变量用于Web服务调用。但是我收到了这个错误。

Traceback (most recent call last):
  File "start.py", line 34, in create_srv
    str(ciEditLine.displayText())
NameError: global name 'ciEditLine' is not defined

编

这是我的第一个应用程序，所以请轻松谢谢。

非常感谢任何帮助。

您必须使用self将对小部件的引用附加到对象：

def __init__(self):
    ...
    self.ciEditLine = QtGui.QLineEdit()        #variable 1
    ...

此外，您需要传递窗口小部件的文本值，而不是窗口小部件引用：

def create_srv(self):
    try:
            response = client.service.createConfigurationItem(self.ciEditLine.text(), self.monitorEditLine.text(), self.bolEditLine.text(), self.ipEditLine.text())

像这样，这些引用成为对象的属性，稍后可以使用self

在任何方法中引用
