What to do if uniapp pictures cannot be displayed

When developing applications using Uniapp, you may encounter situations where images cannot be displayed. This may be due to the following reasons:

1. Path error

The image path in Uniapp should start from the root directory, represented by the "/" symbol. If you use a relative path, the path may be wrong. Make sure your image path is correct.

2. Image size exceeds the limit

When loading images in Uniapp, there will be a size limit. If your image size exceeds the limit, it will not be displayed. You can try reducing the size of the image or adjusting the parameters that limit the size.

3. Server setting issues

If your pictures are obtained from the server, it may be that the server has anti-leeching settings, causing the pictures to fail to display. You can try contacting the server administrator and disabling the anti-hotlink settings.

4. Mobile phone permission issues

In some Android phones, users may need to manually enable the application's storage permissions to load images. You can try adding the following code to the application's manifest.json file to obtain permissions:

"android": { "permissions": [ "android.permission.READ_EXTERNAL_STORAGE", "android.permission.WRITE_EXTERNAL_STORAGE" ] }

If none of the above methods solve your problem, then you can try using plug-ins or component libraries, such as uni-image, etc. , to solve the problem of images not being displayed. When using plug-ins or component libraries, you can carefully study the documentation and sample code to ensure correct use.

In short, no matter what problem you encounter, the most important thing is to analyze and solve it patiently. I wish you good luck in solving your problems in Uniapp development.
