Problem description

Use Chrome browser to access JD mobile terminal, and slider verification fails repeatedly when logging in. Users also pay attention to whether such access is easily identified as coming from the PC side and whether there is a mobile browser similar to Chrome developer tools to facilitate viewing network requests.

Solution

1. Reasons for Chrome slider verification failure:

   JD Mobile is likely to identify and intercept PC access through the following methods:

   • User Agent detection: JD server will check the browser's User Agent information to identify whether it is a mobile device. Chrome's User Agent usually indicates that it is a desktop browser, triggering stricter verification.
   • Screen resolution and device feature recognition: JD.com may judge the access source based on device features such as screen resolution and pixel density. These parameters on the PC side are significantly different from those on mobile devices and are easily identified.
   • Behavior analysis: The slider verification system will analyze the user's mouse movement trajectory, sliding speed and other behavioral characteristics. Operations on Chrome may be judged as non-human because of their accuracy and regularity, resulting in verification failure.

2. Is PC access easy to be recognized?

   Yes, it's very easy. JD Mobile uses a variety of technical means to distinguish between mobile and PC access. The above-mentioned User Agent and device feature detection are two of them.

3. Recommended mobile browsers with developer tools:

   The following mobile browsers provide functions similar to Chrome developer tools to facilitate debugging and viewing network requests:

   • Alook Browser: Provides powerful developer tools to view detailed network request information.
   • Firefox for Android: Firefox for Android also has built-in developer tools for easy access and use.
   • Kiwi Browser: Based on the Chromium kernel, it has a developer tool experience similar to Chrome.
   • Microsoft Edge (Mobile version): Both Android and iOS versions of Edge provide developer tools to facilitate network request analysis.

These browsers can help you efficiently analyze network requests on your mobile device, thereby better understanding and solving JD mobile slider verification problems.
