我尝试用Google Drive文件拾取器下载一个文件（基于这个例子https://gist.github.com/Daniel15/5994054）。文件拾取器在下载文件之前工作正常。它遇到了一个400 Bad-Request（lockedDomainCreationFailure）错误。
下面是代码：

function downloadFile(file, callback) {
  if (file.downloadUrl) {
    var accessToken = gapi.auth.getToken().access_token;
    var xhr = new XMLHttpRequest();
    xhr.open('GET', file.downloadUrl);
    xhr.setRequestHeader('Authorization', 'Bearer ' + accessToken);
    xhr.onload = function() {
      callback(xhr.responseText);
    };
    xhr.onerror = function() {
      callback(null);
    };
    xhr.send();
  } else {
    callback(null);
  }
}

以下是错误消息：

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "lockedDomainCreationFailure",
    "message": "The OAuth token was received in the query string, which this API forbids for response formats other than JSON or XML. If possible, try sending the OAuth token in the Authorization header instead."
   }
  ],
  "code": 400,
  "message": "The OAuth token was received in the query string, which this API forbids for response formats other than JSON or XML. If possible, try sending the OAuth token in the Authorization header instead."
 }
}

它告诉我们在查询字符串中给出了To OAuth令牌，但我认为这是不正确的。

由于我使用的是由Google API提供的下载URL，并且授权是在请求头中给出的，所以我不知道为什么会遇到这个错误。
我很感激你的建议。
