我正在尝试使用nodejs将大型视频文件上传到onedrive存储中。目前,我可以轻松上传小于60 MB的文件。当我要上传大于此的文件时,会出现问题。我收到以下错误->
"error": {
"code": "invalidRange",
"message": "The uploaded fragment is not contiguous with the last one.",
"innererror": {
"code": "fragmentOutOfOrder"
}
}
这是我使用的代码:
var fs = require('fs');
var request = require('request');
var async = require('async');
var client_id = "39bc#####################91";
var redirect_uri = "https://script.google.com/macros/s/#######/usercallback";
var client_secret = "xu##################{";
var refresh_token = "MCSIUo########################w$$";
var file = "videoplayback.mp4"; // Filename you want to upload.
var onedrive_folder = 'uploads'; // Folder on OneDrive
var onedrive_filename = file; // If you want to change the filename on OneDrive, please set this.
function resUpload(){
request.post({
url: 'https://login.microsoftonline.com/common/oauth2/v2.0/token',
form: {
client_id: client_id,
redirect_uri: redirect_uri,
client_secret: client_secret,
grant_type: "refresh_token",
refresh_token: refresh_token,
},
}, function(error, response, body) { // Here, it creates the session.
request.post({
url: 'https://graph.microsoft.com/v1.0/drive/root:/' + onedrive_folder + '/' + onedrive_filename + ':/createUploadSession',
headers: {
'Authorization': "Bearer " + JSON.parse(body).access_token,
'Content-Type': "application/json",
},
body: '{"item": {"@microsoft.graph.conflictBehavior": "rename", "name": "' + onedrive_filename +'"}}',
}, function(er, re, bo) {
uploadFile(JSON.parse(bo).uploadUrl);
});
});
}
function uploadFile(uploadUrl) { // Here, it uploads the file by every chunk.
async.eachSeries(getparams(), function(st, callback){
setTimeout(function() {
fs.readFile(file, function read(e, f) {
request.put({
url: uploadUrl,
headers: {
'Content-Length': st.clen,
'Content-Range': st.cr,
},
body: f.slice(st.bstart, st.bend + 1),
}, function(er, re, bo) {
console.log(bo);
});
});
console.log(st.bstart)
callback();
}, st.stime);
});
}
function getparams(){
var allsize = fs.statSync(file).size;
var sep = allsize < (60 * 1024 * 1024) ? allsize : (60 * 1024 * 1024) - 1;
var ar = [];
for (var i = 0; i < allsize; i += sep) {
var bstart = i;
var bend = i + sep - 1 < allsize ? i + sep - 1 : allsize - 1;
var cr = 'bytes ' + bstart + '-' + bend + '/' + allsize;
var clen = bend != allsize - 1 ? sep : allsize - i;
var stime = allsize < (60 * 1024 * 1024) ? 10000 : 20000;
ar.push({
bstart : bstart,
bend : bend,
cr : cr,
clen : clen,
stime: stime,
});
}
//console.log("Hello2")
return ar;
}
resUpload();
这也是正确的方法吗?如果不是,哪种是上传大文件的最佳方法/代码?
