我尝试如下。但该文件将进入根目录(我的驱动器)。
var metadata = {
'title': fileData.fileName,
'mimeType': contentType,
'parents':["0B6NmmF3ovpsbExuOEc1R2JzSFEp"] // It is one of my folder's id.
};
var base64Data = btoa(reader.result);
var multipartRequestBody =
delimiter +
'Content-Type: application/json\r\n\r\n' +
JSON.stringify(metadata) +
delimiter +
'Content-Type: ' + contentType + '\r\n' +
'Content-Transfer-Encoding: base64\r\n' +
'\r\n' +
base64Data +
close_delim;
var request = gapi.client.request({
'path': '/upload/drive/v2/files',
'method': 'POST',
'params': {'uploadType': 'multipart'},
'headers': {
'Content-Type': 'multipart/mixed; boundary="' + boundary + '"'
},
'body': multipartRequestBody});
request.execute(callback);
