NodeJS使用@esri/arcgis-rest-request时如何调整Fetch请求选项

@esri/arcgis-rest-request 预留了fetchOptions配置位，所有传入该字段的参数都会直接透传给底层调用的fetch方法，可直接用来传入自定义agent配置。

方式1：单次请求生效 #

仅在当前调用的request请求中生效，不会影响其他请求：

import fetch from "node-fetch";
import FormData from "isomorphic-form-data";
import https from "https";
import arcgisRestRequest from "@esri/arcgis-rest-request";

arcgisRestRequest.setDefaultRequestOptions({ fetch, FormData });

// 构造自定义agent
const customHttpsAgent = new https.Agent({
  rejectUnauthorized: false
});

arcgisRestRequest.request("https://www.arcgis.com/sharing/rest/info", {
  // 传入fetch配置
  fetchOptions: {
    agent: customHttpsAgent
  }
})
.then(response => console.log(response));

方式2：全局配置生效 #

所有通过@esri/arcgis-rest-request发起的请求都会自动应用该配置：

import fetch from "node-fetch";
import FormData from "isomorphic-form-data";
import https from "https";
import arcgisRestRequest from "@esri/arcgis-rest-request";

arcgisRestRequest.setDefaultRequestOptions({
  fetch,
  FormData,
  // 全局配置fetch参数
  fetchOptions: {
    agent: new https.Agent({
      rejectUnauthorized: false
    })
  }
});

arcgisRestRequest.request("https://www.arcgis.com/sharing/rest/info")
  .then(response => console.log(response));

注意：关闭rejectUnauthorized校验存在安全风险，仅建议在开发测试环境使用，生产环境请正确部署受信任的HTTPS证书，避免绕过证书校验逻辑。
