模擬提交API數據Pyqt版

其實這個模擬提交數據以前已經寫過篇：

Python requests模擬登陸

 

由於如今在作的項目中須要一個debug請求調試API，用PHP的CURL寫了一個，又因Pyqt更能直觀靈活的顯示請求的參數及獲取的響應參數。因此就更新完善了下以前寫 Python requests模擬登陸

以前這篇用的是Python2.7版本，如今用的是Python3.5的版本從新。

其實就是Pyqt4與Pyqt5直接引用模塊不一樣的關係，PyQt4的QtGui模塊，在PyQt5中被拆分紅三個模塊：QtGui，QtPrintSupport和QtWidgets。

還有一個就是信號槽的變化

老式的信號和槽
PyQt4的舊式的信號和槽再也不被支持。所以如下用法在PyQt5中已經不能使用：

1. QObject.connect()
2. QObject.emit()
3. SIGNAL()
4. SLOT()

全部那些含有參數，而且對返回結果調用SIGNAL()或SLOT()的方法再也不被支持。綁定信號與調用函數老是等效的。
此外，另外一個差別是增長了下面的函數：
disconnect() 斷開全部對 QObject實例的鏈接，不須要參數。
新風格的信號和槽
QT實現的信號與一個可選的參數做爲兩個獨立的信號，一個與論點 和一個沒有它。PyQt4暴露這兩容許你鏈接到他們每一個 。然而，當發射信號，你必須使用適當的參數 發出的信號數。
PyQt5暴露惟一的信號在全部指定參數。然而它 容許任何可選參數被省略時，發射信號。
不一樣於PyQt4，PyQt5支持在類中自定義屬性、信號與槽，即便這個類沒有繼承自QObject（好比：混合類）。

舉幾個Pyqt5信號槽例子：

內置信號槽的使用

from PyQt5.QtWidgets import *  
from PyQt5.QtCore import *  
    
def sinTest():  
    btn.setText("按鈕文本改變")  
    
app = QApplication([])   
main = QWidget()  
main.resize(200,100)  
btn = QPushButton("按鈕文本",main)  
##按鈕btn的內置信號鏈接名爲sinTest的槽  
btn.clicked.connect(sinTest)  
main.show()  
app.exec_()

自定義信號槽的使用

class SinClass(QObject):  
        
    ##聲明一個無參數的信號  
    sin1 = pyqtSignal()  
        
    ##聲明帶一個int類型參數的信號  
    sin2 = pyqtSignal(int)  
        
    ##聲明帶一個int和str類型參數的信號  
    sin3 = pyqtSignal(int,str)  
    
    ##聲明帶一個列表類型參數的信號  
    sin4 = pyqtSignal(list)  
    
    ##聲明帶一個字典類型參數的信號  
    sin5 = pyqtSignal(dict)  
    
    ##聲明一個多重載版本的信號，包括了一個帶int和str類型參數的信號，以及帶str參數的信號  
    sin6 = pyqtSignal([int,str], [str])  
        
    def __init__(self,parent=None):  
        super(SinClass,self).__init__(parent)  
    
        ##信號鏈接到指定槽  
        self.sin1.connect(self.sin1Call)  
        self.sin2.connect(self.sin2Call)  
        self.sin3.connect(self.sin3Call)  
        self.sin4.connect(self.sin4Call)  
        self.sin5.connect(self.sin5Call)  
        self.sin6[int,str].connect(self.sin6Call)  
        self.sin6[str].connect(self.sin6OverLoad)  
    
        ##信號發射  
        self.sin1.emit()  
        self.sin2.emit(1)  
        self.sin3.emit(1,"text")  
        self.sin4.emit([1,2,3,4])  
        self.sin5.emit({"name":"codeio","age":"25"})  
        self.sin6[int,str].emit(1,"text")  
        self.sin6[str].emit("text")  
            
    def sin1Call(self):  
        print("sin1 emit")  
    
    def sin2Call(self,val):  
        print("sin2 emit,value:",val)  
    
    def sin3Call(self,val,text):  
        print("sin3 emit,value:",val,text)  
    
    def sin4Call(self,val):  
        print("sin4 emit,value:",val)  
            
    def sin5Call(self,val):  
        print("sin5 emit,value:",val)  
    
    def sin6Call(self,val,text):  
        print("sin6 emit,value:",val,text)  
    
    def sin6OverLoad(self,val):  
        print("sin6 overload emit,value:",val)  
    
sin = SinClass() 

 

信號槽N對N鏈接、斷開鏈接

from PyQt5.QtWidgets import *  
from PyQt5.QtCore import *  
  
class SinClass(QObject):  
  
    ##聲明一個無參數的信號  
    sin1 = pyqtSignal()  
  
    ##聲明帶一個int類型參數的信號  
    sin2 = pyqtSignal(int)  
  
    def __init__(self,parent=None):  
        super(SinClass,self).__init__(parent)  
  
        ##信號sin1鏈接到sin1Call和sin2Call這兩個槽  
        self.sin1.connect(self.sin1Call)  
        self.sin1.connect(self.sin2Call)  
  
        ##信號sin2鏈接到信號sin1  
        self.sin2.connect(self.sin1)  
  
        ##信號發射  
        self.sin1.emit()  
        self.sin2.emit(1)  
  
        ##斷開sin一、sin2信號與各槽的鏈接  
        self.sin1.disconnect(self.sin1Call)  
        self.sin1.disconnect(self.sin2Call)  
        self.sin2.disconnect(self.sin1)  
  
        ##信號sin1和sin2鏈接同一個槽sin1Call  
        self.sin1.connect(self.sin1Call)  
        self.sin2.connect(self.sin1Call)  
  
        ##信號再次發射  
        self.sin1.emit()  
        self.sin2.emit(1)  
  
    def sin1Call(self):  
        print("sin1 emit")  
  
    def sin2Call(self):  
        print("sin2 emit")  
  
sin = SinClass()  

多線程信號槽通訊

from PyQt5.QtWidgets import *
from PyQt5.QtCore import *


class Main(QWidget):
    def __init__(self, parent=None):
        super(Main, self).__init__(parent)

        ##建立一個線程實例並設置名稱、變量、信號槽
        self.thread = MyThread()
        self.thread.setIdentity("thread1")
        self.thread.sinOut.connect(self.outText)
        self.thread.setVal(6)
        
        self.t2=MyThread()
        self.t2.setIdentity('ttt')
        self.t2.sinOut.connect(self.outText)
        self.t2.setVal(10)

    def outText(self, text):
        print(text)


class MyThread(QThread):
    sinOut = pyqtSignal(str)

    def __init__(self, parent=None):
        super(MyThread, self).__init__(parent)
        print('b')

        self.identity = None

    def setIdentity(self, text):
        self.identity = text
        print('b1')

    def setVal(self, val):
        self.times = int(val)
        print('b2')

        ##執行線程的run方法
        self.start()
        print('c')

    def run(self):
        print(self.times )
        while self.times > 0 and self.identity:
            ##發射信號
            self.sinOut.emit(self.identity + " " + str(self.times))
            self.times -= 1


app = QApplication([])
main = Main()
main.show()
app.exec_()
