Common Library Subsystem Changelog

Compared with OpenHarmony 3.2 Beta4, OpenHarmony 3.2.10.1(MR) has the following API changes in the URL module of the common library subsystem.

cl.commonlibrary.1 URLParams Class Changes

The constructor function of the URLParams class in the URL module of the common library subsystem is changed.

Specifically, constructor(init?: string[][]|Record|string|URLSearchParams) is changed to constructor(init?: string[][]|Record|string|URLParams), and the parameter type is changed from URLSearchParams to URLParams.

You need to adapt your application.

Change Impacts

JS APIs in API version 9 are affected. Your application needs to adapt these APIs so that it can properly implement features in the SDK environment of the new version.

@ohos.url	URLParams	constructor(string[][] \|Record<string, string> \|string \|URLSearchParams)	Deleted
@ohos.url	URLParams	constructor(string[][] \|Record<string, string> \|string \|URLParams)	Changed

Adaptation Guide

The following illustrates how to create a URLParams object in your application.

Example:

import url from '@ohos.url'
try {
    let params1 = new Url.URLParams('?user=abc&query=xyz')
    let params2 = new Url.URLParams(params1)
    var result= params2.toString()
    console.log(result) //"user=abc&query=xyz"
} catch (err) {
    console.error(`Fail to ceate URLParams.codeis${err.code},message is ${err.message}`);
}
