Answer 1

There are a few things you need to modify to get this working (tested on my end):
To get the contents of the file, you need $request->file('file') and then use file_get_contents() on it. You can lose the get() part.
Make sure you're sending the header to accept multipart/form-data too:
"Accept" => "multipart/form-data"
Fields name and filename in a form are two different things. Former is the name of the field while the latter is the name of the file. You need to send both.
Try this:
protected function uploadFile(Request $request){
$file = $request->file('file');
$body = [
"headers" => [
"Accept" => "multipart/form-data",
"Authorization" => "Bearer {$this->token}"
],
"multipart" => [
"name" => "file",
"contents" => file_get_contents($file),
"filename" => $file->getClientOriginalName()
]
];
return (new Client)->request('POST', 'https://.sharepoint.com/...', $body);
}
P.S. - You can check whether a file is valid or not using isValid():
if ($request->file('file')->isValid()) {
//
}

Answer 2

When providing content to be uploaded to Guzzle client as string,
Guzzle tries to infer necessary information about the file such as filename, content-type.
You can help Guzzle to infer these information correctly to build the multipart request by passing information about about the filename and content-type in the multipart payload.
[
//...
'multipart' => [
[
'name' => 'fileName',
'contents' => $request->file('file')->get(),
'filename' => $request->file('file')->getName(),
'headers' => [
'content-type' => $request->file('file')->getMimeType(),
]
]
]
]

Answer 3

Add content-type as blob.
axios.post(
'https://sharepoint....'
,data.get('file')
{
'headers' {
'Authorization': `Bearer ${this.token}`
,'Content-Type': 'blob',
}
}
)

Answer 4

Try something like this.
Remove the ->get() of your $request->file()
//Get the file object from the request.
$file = $request->file('file');
//Make the request
return (new Client)->request('POST', 'https://.sharepoint.com/sites....', [
'headers' => [ 'Authorization' => "Bearer {$this->token}" ],
'multipart' => [
[
'name' => 'FileContents',
'contents' => $file,
'filename' => $file->getClientOriginalName()
],
],
]);

In my opinion, you should store it somewhere in your local server temporarily first, and then you sent that file to sharepoint, deleted the temporary file, I think if you send it right away without storing it, the file will be corrupted. Please try the way below
$file = $request->file('logo');
$original_name = $file->getClientOriginalName(); // get original file
$name = time() . '_' . $original_name; // store it in different name so it would not be duplicated
$path = base_path() .'/public_html/your_project/public/temporary/'; // full path of file folder
// store the uploaded file
$file->move($path, $name);
$body = [
"headers" => [
"Authorization" => "Bearer {$this->token}"
],
"multipart" => [
"name" => "logo",
"contents" => fopen($path . $name, 'r')
]
];
$response = (new Client)->request('POST', 'https://.sharepoint.com/...', $body);
// remove the file after done
unlink($path . $name);
return $response;
Hope this would work for you! Please correct me if I was wrong
