Post request by QWebEngineHttpRequest (PyQt5)


I have a question about making POST request in PyQt5. Unfortunately official documentation for this framework for Python doesen't exist. I have to translate docs from C++ to Python.

I have a problem with handle it. To make POST request I have to create instance of class QWebEngineHttpRequest (docs), and then add POST data by setPostData(), it looks to be easy, but that method requires a parameter in type QByteArray (docs), and here is a problem because i don't know how to insert data into this.


Solution

  • I know I'm late, but I hope it helps someone else with the same issue. Here's how I've done it:

    def postRequest(self):
        self.url = QUrl()
        self.req = QWebEngineHttpRequest()
    
        self.url.setScheme("http")
        self.url.setHost("stackoverflow")
        self.url.setPath("/something/somethingelse")
    
        self.req.setUrl(self.url)
        self.req.setMethod(QWebEngineHttpRequest.Post)
        self.req.setHeader(QByteArray(b'Content-Type'),QByteArray(b'application/json'))
    
        params = {"something": value, "test": True, "number": 5}
    
        self.req.setPostData(bytes(json.dumps(params), 'utf-8')) 
        
        return self.req
