用PHP设置PUT请求体

Question

I'm trying to use the Google Sheets API's spreadsheets.values.update (https://developers.google.com/sheets/reference/rest/v4/spreadsheets.values/update) method to insert data into a spreadsheet.

I've already acquired a correctly scoped access token, and now I'm trying to send a PUT request via cURL. I'm using the PHP curl wrapper (https://github.com/php-curl-class/php-curl-class) but plain PHP would also be great.

Here's what I have so far:

$curl = new Curl();
    $curl->setHeader("Authorization","Bearer ".json_decode($a4e->user->google_token)->access_token);
    $curl->setOpt(CURLOPT_POSTFIELDS, '{"values": [["Elizabeth", "2", "0.5", "60"]]}');
    $curl->put('https://sheets.googleapis.com/v4/spreadsheets/11I1xNv8cHzBGE7uuZtB9fQzbgrz4z7lIaEADfta60nc/values/Sheet1!A1', array(
        'valueInputOption' => 'USER_ENTERED'    
    ));

    if ($curl->error) {
        echo 'Error: ' . $curl->errorCode . ': ' . $curl->errorMessage;
    }
    else {
        echo json_encode($curl->response);
    }

The cURL request executes successfully, and returns the following:

{"spreadsheetId":"11I1xNv8cHzBGE7uuZtB9fQzbgrz4z7lIaEADfta60nc","updatedRange":"Sheet1!A1"}

However, it does not update the data in the sheet.

Does anyone know what I am doing wrong? Many thanks in advance.

Answer 1

OK, so I ran the parameters through Postman (https://chrome.google.com/webstore/detail/postman/fhbjgbiflinjbdggehcddcbncdddomop?hl=en) and exported the following code:

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://sheets.googleapis.com/v4/spreadsheets/11I1xNv8cHzBGE7uuZtB9fQzbgrz4z7lIaEADfta60nc/values/Sheet1!A1?valueInputOption=USER_ENTERED",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "PUT",
  CURLOPT_POSTFIELDS => "{\"range\":\"Sheet1!A1\",\"majorDimension\":\"ROWS\",\"values\":[[\"x\",\"x\",\"x\",\"x\",\"x\"]]}",
  CURLOPT_HTTPHEADER => array(
    "authorization: Bearer {token}",
    "cache-control: no-cache",
    "content-type: application/json",
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

And it finally works! The content-type: application/json is absolutely essential, as per RomanPerekhrest's suggestion. The request doesn't update anything without it.
