Google Drive API V3(javascript)更新文件内容
我想使用Google Drive API V3(javascript)更新Google文档的内容: 我可以更新文件元数据(例如名称),但是文档中没有包含实际文件内容的补丁语义。是否有方法在Google Drive API V3(javascript)更新文件内容,javascript,google-drive-api,Javascript,Google Drive Api,我想使用Google Drive API V3(javascript)更新Google文档的内容: 我可以更新文件元数据(例如名称),但是文档中没有包含实际文件内容的补丁语义。是否有方法在gapi.client.drive.files.update请求中将JSON.stringify()值作为参数传递: var request = gapi.client.drive.files.update({ 'fileId': fileId, 'name' : 'Updated File
gapi.client.drive.files.update
请求中将JSON.stringify()
值作为参数传递:
var request = gapi.client.drive.files.update({
'fileId': fileId,
'name' : 'Updated File Name',
'uploadType': 'media',
'mimeType' : 'application/vnd.google-apps.document'
});
var fulfilledCallback = function(fulfilled) {
console.log("Update fulfilled!", fulfilled);
};
var rejectedCallback = function(rejected) {
console.log("Update rejected!", rejected);
};
request.then(fulfilledCallback, rejectedCallback)
有两个问题:
function updateFileContent(fileId, contentBlob, callback) {
var xhr = new XMLHttpRequest();
xhr.responseType = 'json';
xhr.onreadystatechange = function() {
if (xhr.readyState != XMLHttpRequest.DONE) {
return;
}
callback(xhr.response);
};
xhr.open('PATCH', 'https://www.googleapis.com/upload/drive/v3/files/' + fileId + '?uploadType=media');
xhr.setRequestHeader('Authorization', 'Bearer ' + gapi.auth.getToken().access_token);
xhr.send(contentBlob);
}
要解决问题#2,您可以向驱动器发送Google Docs可以从中导入的文件类型,如.txt、.docx等。以下代码使用上述函数使用纯文本更新Google Doc的内容:
function run() {
var docId = '...';
var content = 'Hello World';
var contentBlob = new Blob([content], {
'type': 'text/plain'
});
updateFileContent(fileId, contentBlob, function(response) {
console.log(response);
});
}
我构建了gDriveSync.js库,使用javascript v3 api与google drive同步 您可以检查我所做的()的源代码,基本上是一个两步过程,首先创建文件,然后更新它
this.saveFile = function(file, done) {
function addContent(fileId) {
return gapi.client.request({
path: '/upload/drive/v3/files/' + fileId,
method: 'PATCH',
params: {
uploadType: 'media'
},
body: file.content
})
}
var metadata = {
mimeType: 'application/vnd.google-apps.document',
name: file.name,
fields: 'id'
}
if (file.parents) {
metadata.parents = file.parents;
}
if (file.id) { //just update
addContent(file.id).then(function(resp) {
console.log('File just updated', resp.result);
done(resp.result);
})
} else { //create and update
gapi.client.drive.files.create({
resource: metadata
}).then(function(resp) {
addContent(resp.result.id).then(function(resp) {
console.log('created and added content', resp.result);
done(resp.result);
})
});
}
}
假设您已经将令牌存储在名为
tokens
的变量中,您可以使用node js google API通过fetch来实现这一点:
fetch("https://www.googleapis.com/upload/drive/v3/files/ID_OF_DRIVE_FILE?uploadType=media",
{
headers: {
'Content-Type':'multipart/related; boundary=a5cb0afb-f447-48a6-b26f-328b7ebd314c',
'Accept-Encoding': 'gzip',
'User-Agent': 'google-api-nodejs-client/0.7.2 (gzip)',
Authorization:tokens.token_type +" "+ tokens.access_token,
Accept:"application/json"
},
method:"PATCH",
body: "OK now iasdfsdgeaegwats AGAIN intresting",
cb(r) {
}
}).then(r => {
console.log(r);
});
