问题描述
google drive api v3
我需要更改现有对象的描述。我该如何更改,其余的保持不变?
我正在用python做类比。我得到文件元数据,在其中添加“描述”行并执行更新。没有错误,说明根本不会改变
我对js不太了解,如果您能帮助我,我会很高兴。
谢谢
function updateFile(fileId) {
var request = gapi.client.drive.files.get({
'fileId': fileId
});
request.execute(function(resp) {
var data = resp;
//data = data['result']
data['description'] = "433434"
});
var fileMetadata = data;
const boundary = '-------314159265358979323846';
const delimiter = "\r\n--" + boundary + "\r\n";
const close_delim = "\r\n--" + boundary + "--";
var reader = new FileReader();
reader.readAsBinaryString(fileData);
reader.onload = function(e) {
var contentType = fileData.type || 'application/octet-stream';
// Updating the Metadata is optional and you can instead use the value from drive.files.get.
var base64Data = btoa(reader.result);
var multipartRequestBody =
delimiter +
'Content-Type: application/json\r\n\r\n' +
JSON.stringify(fileMetadata) +
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/v3/files/' + fileId,'method': 'PATCH','params': {'uploadType': 'multipart','alt': 'json'},'headers': {
'Content-Type': 'multipart/mixed; boundary="' + boundary + '"'
},'body': multipartRequestBody
});
if (!callback) {
callback = function(file) {
console.log(file)
};
}
request.execute(callback);
};
}
解决方法
谢谢大家,我解决了我的问题。这是代码,它对我有用)
function updateFile(fileId) {
var request = gapi.client.drive.files.get({
'fileId': fileId
});
request.execute(function(resp) {
fileMetadata = resp;
fileMetadata['description'] = "new_description";
delete fileMetadata.id;
var request = gapi.client.request({
'path': '/drive/v3/files/' + fileId,'method': 'PATCH','body': fileMetadata});
request.execute(function(resp) {
});
})
}
