如何在HttpParams中设置字符串数组？

const { HttpClient } = require('your-http-client-module');

const httpClient = new HttpClient();

const params = new HttpParams();
params.set('paramName', ['value1', 'value2', 'value3']); // 设置字符串数组

httpClient.get('/api/endpoint', { params }).subscribe(response => {
  console.log(response);
}, error => {
  console.error(error);
});

const params = new URLSearchParams();
params.append('paramName', 'value1');
params.append('paramName', 'value2');
params.append('paramName', 'value3');

const url = `/api/endpoint?${params.toString()}`;

fetch(url)
  .then(response => {
    console.log(response);
  })
  .catch(error => {
    console.error(error);
  });
