[求助]请问这种请求咱们可以直接通过"HTTP请求"模块发送请求吗？这个请求内容怎么写呀

内容：

fetch("http://10.154.88.145:8000/svg/files/SvgDataServlet", {
  "headers": {
    "accept": "application/xml, text/xml, */*; q=0.01",
    "accept-language": "zh-CN,zh;q=0.9",
    "content-type": "application/x-www-form-urlencoded; charset=UTF-8",
    "x-requested-with": "XMLHttpRequest"
  },
  "body": "<root><SVGData all_keyid=\"6635232322_100000_1,22365411_100000_1\" app_id=\"100000\" graph_type=\"fac\" graph_name=\"FD454DA4D5A4SD5A4D54AD4X1DAS54DAD4A54454SADA6\"/></root>",
  "method": "POST",
  "mode": "cors",
  "credentials": "include"
});

注：6635232322_100000_1,22365411_100000_1为请求设备的ID；

<root><SVGData all_keyid=\"......"/></root>这个是什么意思呢，咱们的请求体怎么写呐？
