How to upload a file to OneDrive using OneDrive REST API?

Question

Please allow me to explain what I am doing and How I am doing.

What I am doing?

I am trying to upload a file to Onedrive using its REST API Source: one drive api documentation

I am using OneDrive fragments approch to do so as the file can be as huge as 5gb or as small as 1kb (Depends on the user)

Currently, I am doing it using POST-MAN Chrome extention to call APIes

How am I doing?

1. Generated Access token
2. Created Session and received Uploading url
3. Uploading file using PUT request as given below

Selected file that I want to upload (File Size: 729676295 bytes)

Added headers and sent the request and sent the request Here is the result

it is saying that the maximum fragment size is 67108864 bytes so I changed the value of

content-length : 67108864 and content-range : bytes 0-67108863/729676295

but then I get this error message: Declared fragment length does not match the provided number of bytes

Please help me to figure out what should I pass in content-length and content-range.

Many Thanks for you attention.

Answer 1

Finally, thanks to god after 2 days of struggle I found what was the problem.

There are some points that you need to keep in mind

1. You have to divide a file to into equal parts and save it somewhere and upload each of them separately on the same URL that you get after creating a session.
2. Content-Length must be the total numbers of bytes of the file that you are uploading in all upload requests of fragments.
3. Content-Range will be like: 0-{fragmentLength-1}/{totalNumberOfBytesOfFile}(same as content-length) and from next fragment the Content-Range will be {uploadedBytes}-{uploadedBytes+nextSetOfBytes-1}/{totalNumberOfBytesOfFile}

Note: The Next set of bytes should be as long as the previous was. Do not worry because the last fragment can be different.

P.S: Do not use the content-range that you will receive after successfully uploading the fragment.

Answer 2

{totalNumberOfBytesOfFile} is not same as content-length;

Content-Length is bytes of current fragment.

the image is an a example for upload a 4917 bytes file.
