What are the loopholes in uniapp?

As the mobile application market continues to expand, technology based on multi-terminal development has also been continuously developed. As a multi-terminal development framework, UniApp has been favored by many developers since its launch. Although UniApp has made great contributions in multi-terminal development, it is inevitable that there are some loopholes and problems.

UniApp is a multi-terminal application development solution based on the vue.js framework. It can run the same set of code on different platforms (including H5, applets, iOS, Android), and also supports conversion between multiple platforms. This undoubtedly greatly facilitates the work of developers.

However, there are also some loopholes and problems during the use of UniApp. Some major loopholes and countermeasures will be introduced below.

1. Code Security Issues

With the widespread use of UniApp, attackers are increasingly turning their attention to UniApp. UniApp developers still have some security issues when writing code.

For example, when using uni.request to send network requests, if the requested address is not processed securely, some security issues may occur. In addition, if the application does not impose reasonable security restrictions on uni.openBluetoothAdapter and other open interfaces, attackers can attack through these interfaces.

For these problems, developers need to reasonably avoid and handle them when writing code. For example, the request address of uni.request can be controlled using a whitelist to restrict requests from being sent to trusted servers; at the same time, the interface parameters also need to be rationally filtered and verified.

2. Runtime issues

After writing the code in UniApp, we need to package the code to run on various platforms. There are also some problems during this operation.

Currently, most WeChat applets run based on jssdk. Due to the limitations of the vue.js framework, uniapp cannot fully support all functions of jssdk, so developers may encounter some problems during operation.

In response to these problems, developers need to make appropriate adjustments and processing for different platforms based on actual conditions.

3. Mini program compilation issues

UniApp supports converting H5 applications directly into mini program applications, which greatly reduces the tedious operations of developers. However, some problems may still arise during the conversion process.

For example, some npm packages used in UniApp may not be used properly in the mini program. In this case, developers need to manually add relevant dependencies to the mini program project. In addition, when UniApp converts H5 applications into mini-app applications, larger image resources may be ignored or compressed. Developers also need to pay attention to this.

4. Process Issues

During the development process, UniApp also has some problems and pain points. For example, during the application development process, UniApp used technologies such as the vue.js framework, which caused some lags and delays in the application.

In response to this problem, developers need to optimize appropriately. Defining the cost of Vuex in advance and reducing the cost of frequent calculations can alleviate this situation and improve the response speed of the application.

Overall, the risks faced by UniApp are similar to those of regular web applications. These problems are also common in other platforms and frameworks, and developers need to consciously avoid problems and make appropriate adjustments and optimizations. At the same time, when using UniApp, you also need to develop in accordance with development specifications and best practices, which can greatly reduce the risk of security issues and other vulnerabilities and improve the reliability and security of the application.
