HarmonyOS 有没有URLEncoder组件？

@Entry
@Component
struct MainPage {
    @State private originalString: string = "Hello World! 你好，世界！";
    @State private encodedString: string = "";
    @State private decodedString: string = "";

    build() {
        Column({ space: 20, alignItems: ItemAlign.Center }) {
            Text("Original String:")
                .fontSize(20)
            Text(this.originalString)
                .fontSize(16)

            Button("Encode")
                .onClick(() => {
                    this.encodedString = encodeURIComponent(this.originalString);
                    this.decodedString = "";
                })

            if (this.encodedString !== "") {
                Text("Encoded String:")
                    .fontSize(20)
                Text(this.encodedString)
                    .fontSize(16)

                Button("Decode")
                    .onClick(() => {
                        this.decodedString = decodeURIComponent(this.encodedString);
                    })
            }

            if (this.decodedString !== "") {
                Text("Decoded String:")
                    .fontSize(20)
                Text(this.decodedString)
                    .fontSize(16)
            }
        }.padding(20)
    }
}
