When logging in with WeChat, you will sometimes encounter the situation where the pop-up window becomes blank after the QR code is successfully scanned and the main window is not refreshed. This article will analyze this problem and provide corresponding solutions.
Users click on WeChat to scan the code to log in, and the pop-up window is used to scan the code. After the QR code is successfully scanned, the Django backend returns:
<code>httpresponse("window.opener.location.reload();window.close();", content-type="text/html; charset=utf-8 ")</code>
Expected result: The small window is closed and the main window is refreshed. But the actual result is: the small window is blank and the main window is neither closed nor refreshed. The browser does not set any blocking mechanism, and other websites operate similarly normally.
The problems may lie in the following aspects:
Incomplete HTML structure : The backend returns not a complete HTML page, but just JavaScript code. The browser cannot parse correctly, resulting in a blank small window.
Error Content-Type :
content-type
header information is set incorrectly, and the browser cannot recognize that the return content is HTML.Same-origin policy restrictions :
window.opener
is used to operate the parent window. If the domain name of the small window and the main window is different, it may be subject to the same-origin policy restrictions.Browser Compatibility : Some browsers may have compatibility issues.
Solution:
-
Returns the full HTML structure : The backend should return the full HTML page, for example:
<meta charset="UTF-8"> <title>Login successfully</title> <script> window.opener.location.reload(); window.close(); </script>
Set the correct Content-Type : Make sure
content-type
is set to"text/html; charset=utf-8"
.Check the same-origin policy : Make sure that the domain name of the small window and the main window is consistent.
Browser compatibility testing : Test on different browsers (Chrome, Firefox, Safari, etc.) to troubleshoot browser compatibility issues.
Through the above steps, the problem of blank small windows and unrefreshed main windows after scanning the QR code on WeChat can be effectively solved, improving user experience.
