求告知如何发起HTTP请求

配置网络权限。

导入远场通信服务模块。

配置Request参数。

创建会话并发送请求。

//步骤一，在JSON文件src/main/module.json5的module属性中加入
"requestPermissions": [
{
  "name": "ohos.permission.INTERNET"
}

//步骤二
import { rcp } from "@kit.RemoteCommunicationKit";
import { BusinessError } from '@kit.BasicServicesKit';

//步骤三
let headers: rcp.RequestHeaders = {
  "accept": "application/json"
};
let content = "data to send";
let configuration: rcp.Configuration = {
  transfer: {
    autoRedirect: true,
    timeout: { connectMs: 60000, transferMs: 60000 },
  },
  tracing: {
    verbose: true,
  }
};
let cookies: rcp.RequestCookies = { 'name1': 'value1', 'name2': 'value2' };
let transferRange: rcp.TransferRange = { from: 100, to: 200 };
let req = new rcp.Request("http://example.com", "POST", headers, content, cookies, transferRange, configuration);

//步骤四
let session = rcp.createSession();
session.fetch(req).then((response) => {
  console.log(JSON.stringify(response));
  session.close();
}).catch((err: BusinessError) => {
  console.error("err:" + err);
  session.close();
});
