签名不过有遇到过吗

// 火山OCR
import { Signer } from '@volcengine/openapi';
import qs from 'querystring'
import axios from 'axios'

const accessKeyId = "xxxx"
const secretKey = "xxx=="

// @ts-ignore
function getAuth() {
  // http request data
  const openApiRequestData = {
    region: 'cn-north-1',
    method: 'POST',
    // [optional] http request url query
    params: {
      Action: 'OCRNormal',
      Version: '2020-08-26'
    },
    // http request headers
    headers: {
      // 'content-type': 'application/x-www-form-urlencoded',
      // 'host': 'open.volcengineapi.com'
    },
    // [optional] http request body
    body: "",
  }

  const signer = new Signer(openApiRequestData, "cv");

  // sign
  signer.addAuthorization({ accessKeyId, secretKey });

  // Print signed headers
  return openApiRequestData.headers
}

const pickUp = async(imgUrl:string):Promise<any> => {
  const auth = getAuth()
  const query = {
    Action: 'OCRNormal',
    Version: '2020-08-26'
  }
  
  try {
    const data = await axios({
      url: `https://visual.volcengineapi.com?${qs.stringify(query)}`,
      method: "post",
      data: {
        image_url: imgUrl
      },
      headers: {
        // ...form.getHeaders(),
        // 'content-type': 'application/x-www-form-urlencoded',
        ...auth
      }
    })
    return data;
  } catch (error) {
    console.log('error=======>', error)
  }
}

报签名不通过，究竟是啥原因

我这样写通过了。参考官方文档 https://www.volcengine.com/docs/6349/127695

const credentials = {
  accessKeyId: 'AKLTOTliNzY4M2ViYjQ4NDBmZGSDASDFDSFSDFDSSDFE',
  secretKey: 'TWpsbE9HWXhaVEk0TjJabVSDFSDFSDFSDFeVlqUTVOMlExWlRVd01tVQ==',
  sessionToken: '',
};

const openApiRequestData = {
  method: 'GET',
  region: 'cn-beijing',
  params: {
    Action: 'AssumeRole',
    Version: '2018-01-01',
    RoleTrn: 'trn:iam::2105023003:role/xxx_role',
    RoleSessionName: 'test',
  },
};

const signer = new Signer(openApiRequestData, 'sts');
signer.addAuthorization(credentials);  // 此时已经能获得 signer.request.headers，如果不需要获取临时 token 则不需要下面的代码

// 下面的代码是获取临时token的，比如浏览器上传文件到火山，则浏览器先向 node server 请求临时token，浏览器使用临时 token 再上传文件到火山，避免浏览器直接使用正式的secret上传

const url =
  'https://open.volcengineapi.com?' + new URLSearchParams(openApiRequestData.params).toString();

const res = await axios.get(url, {
  headers: signer.request.headers,
});
console.log(res.data); // 临时 token
