Javascript 在GAS上使用基本身份验证API JSON时出现错误400

我正试图通过Google应用程序脚本上的应用程序使用下载文件，但出现以下错误：

<?xml version="1.0" encoding="UTF-8"?>
  <Error>
    <Code>InvalidArgument</Code>
    <Message>Only one auth mechanism allowed; only the X-Amz-Algorithm 
      query parameter, Signature string parameter or the Authorization header 
      should be specified</Message>
    <ArgumentName>Authorization</ArgumentName>
    <ArgumentValue>Basic ENCODED ID </ArgumentValue>
    <RequestId> REQUEST ID </RequestId>  
    <HostId> HOST ID </HostId>
</Error>

有人知道那是什么吗？我发现了一些关于重新发送头授权的信息，但我不知道如何在GAS上这样做

请在下面找到我的代码：

function zamzar() {
  var url = "https://sandbox.zamzar.com/v1/jobs";
  var user = API KEY;
  var headers = {
    "Authorization": "Basic "+ Utilities.base64Encode(user+":"),
    "followRedirect": false
  };
  var options = {
    "method" : "post",
    "headers" : headers, 
    "muteHttpExceptions" : true,
  };  
  upload(url, headers, options);
}

function upload(url, headers, options) {
  var formData = {
    "source_file" : "http://www.sinduscon-rs.com.br/wp-content/uploads/2018/06/VALORES-DOS-CUBS.pdf", //pdf that will be converted to XLS
    "target_format" : "xls",
  }
  options["payload"] = formData;  
  var response = UrlFetchApp.fetch(url,options);
  checkConversion(response, headers); 
}

function checkConversion(response, headers) {  
  Utilities.sleep(10000) // wait 10 seconds to finish conversion  
  var JSONresponse = JSON.parse(response, headers)
  var jobID = JSONresponse.id;
  var url = "https://sandbox.zamzar.com/v1/jobs/" + jobID;  
  var options = {
    "method" : "get",
    "headers" : headers, 
    "muteHttpExceptions" : true,
  };    
  var response = UrlFetchApp.fetch(url,options);  
  var checkResponse = JSON.parse(response);
  download(checkResponse, headers); 
}

function download(checkResponse, headers) {
  var xlsID = checkResponse.target_files[0].id;
  var url = "https://sandbox.zamzar.com/v1/files/" + xlsID + "/content";
  var options = {
    "method" : "get",
    "headers" : headers,
    "muteHttpExceptions" : true,
  };    
  var response = UrlFetchApp.fetch(url,options);

  Logger.log(response);
}

@谢谢你的回复！生成错误的

UrlFetchApp.fetch

是

download（）

函数中的错误。您确定可以使用驱动API将PDF转换为Google工作表吗？我只能找到转换为Google文档的文档。抱歉，您是正确的-PDF的ocr/转换将只映射到文档文件：。考虑建立要发送的请求并检查它，以获得错误引用的多个授权参数。谢谢你的提示！我将请求附在原始问题之后。我真的不明白那是什么意思。你知道怎么了吗？可能与你的情况有关。您是否能够查看出现错误的响应对象？如果是这样，将其与发送的请求进行比较可能也会有所帮助@再次谢谢你！我再次编辑了我的问题，以包含回答
