HarmonyOS 如何提个远程的txt链接读取为string

fs.readTextSync好像不支持读取远程链接，我想读取https://example-files.online-convert.com/document/txt/example.txt 这个链接的内容，请问有合适的api吗

let readTextOptions: ReadTextOptions = {
  offset: 1,
  length: 0,
  encoding: 'utf-8'
};
let stat = fs.statSync(this.url);
readTextOptions.length = stat.size;
let str = fs.readTextSync(this.url, readTextOptions);
