Here is Create File Permission API Sample Request Data

POST https://www.googleapis.com/drive/v3/files/FILE_ID/permissions

{
  "requests": [
    {
        "type": "user",
        "role": "commenter",
        "emailAddress": "nancyxxxx@gmail.com"
    }
  ]
}

I have tried 2 sample Code below

Below is my sample code 1.

   $access_token = 'xxxxxxxxxxxx';
  $file_id ='file id goes here';


$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/drive/v3/files/$file_id/permissions");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    "Authorization: Bearer $access_token",
    'Content-Type: application/x-www-form-urlencoded'
]);
//curl_setopt($ch, CURLOPT_POSTFIELDS, "{\n  \"requests\": [\n    {\n        \"type\": \"anyone\",\n        \"role\": \"reader\"\n\n    }\n  ]\n}");
  //curl_setopt($ch, CURLOPT_POSTFIELDS, '{\n  "requests": [\n    {\n        "type": "anyone",\n        "role": "reader"\n\n    }\n  ]\n}');
  curl_setopt($ch, CURLOPT_POSTFIELDS, "{\n  \"requests\": [\n    {\n        \"type\": \"anyone\",\n        \"role\": \"reader\"\n\n    }\n  ]\n}");


$response = curl_exec($ch);

curl_close($ch);

var_dump($response);

Below is my sample code 2.

       $access_token = 'xxxxxxxxxxxx';
      $file_id ='file id goes here';
$headers = array(
"Authorization: Bearer $access_token",
"Content-Type: application/json"
);

$post_fields = '{
  "requests": [
    {
        "type": "anyone",
        "role": "reader"
    }
  ]
}';

 

$ch = curl_init();                                                       
curl_setopt($ch, CURLOPT_URL, "https://www.googleapis.com/drive/v3/files/$file_id/permissions");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
$response = curl_exec($ch);

var_dump($response);

Here is the error both 2 code above throws

{ "error": { "code": 400, "message": "The permission type field is required.", "errors": [ { "message": "The permission type field is required.", "domain": "global", "reason": "required", "location": "permission.type", "locationType": "other" } ] } } string(323) "{ "error": { "code": 400, "message": "The permission type field is required.", "errors": [ { "message": "The permission type field is required.", "domain": "global", "reason": "required", "location": "permission.type", "locationType": "other" } ] } } "

it seems this permmission request data below is not properly passed in the API or that Googgle Drive Rest API has some bugs. Can someone help me out.

{
      "requests": [
        {
            "type": "anyone",
            "role": "reader"
    
        }
      ]
    }

Solution

In your script, please modify your request body in your "Below is my sample code 2." as follows and test it again.

From:

$post_fields = '{
  "requests": [
    {
        "type": "anyone",
        "role": "reader"
    }
  ]
}';

To:

$post_fields = '{"type": "anyone", "role": "reader"}';
