我有这段代码可以将一个进程的所有输出打印到一个文本字段中:
I have this code to print into a text field all the output from a process:
data = self.m_process.readAllStandardOutput()
s = str(data)
self.m_ui.b_renderOutput.append(s)
我在输出中得到的是:
b''
b''
b''
b'
Starting "C:\Program Files'
b''
b'\Autodesk\Maya2018\bin\mayabatch.exe"
'
b'Initialized VP2.0 renderer {
'
我无法将其解码并以正确的方式打印.我知道来自 readAllStandardOutput 的是 QByteArray
I'm not able to decode it and print it in the right way. I know that what comes from readAllStandardOutput is a QByteArray
如果要转换 QByteArray 为字符串，首先使用 data 将其转换为字节() 方法，然后是 decode() 将其转换为字符串:
If you want to convert QByteArray to string, first convert it to bytes using the data() method, and then decode() to convert it to string:
data = self.m_process.readAllStandardOutput()
s = data.data().decode() # <---
self.m_ui.b_renderOutput.append(s)
另一种方法是将 QByteArray 转换为 bytearray 然后使用 decode():
Another method is to convert the QByteArray to bytearray and then use decode():
data = self.m_process.readAllStandardOutput()
s = bytearray(data).decode() # <---
self.m_ui.b_renderOutput.append(s)
