使用Paypal REST API和PHP cURL發布發票（草稿）不斷返回415不支持的媒體類型

Question

我在他們的網站上使用paypal的創建發票樣本json

我得到一個令牌足夠好，我用帖子提交，因為錯誤不是401未經授權而是415不支持的媒體類型（現在最近500內部服務器錯誤）讓我相信我可能會得到那部分是正確的...所以我會提供一些代碼，希望有人能抓住一些我不知道的東西：

createPaypalInvoice.php

function paypalCreateDraftRequest($token,$jsondraft){
    global $url;
    $sUrl = "/v1/invoicing/invoices";
    $accept = "Accept:application/json";
    $acceptlang = "Accept-Language:en_US";
    $contenttype = "Content-Type: application/json";
    $contentlen = "Content-Length: " . strlen($jsondraft);
            // $jsondraft is a string of json from paypal example
    $authorization = "Authorization: Bearer ".$token["access_token"];
    $headers = array($accept,$acceptlang,$contenttype,$contentlen,$authorization);
    $fields_string = $jsondraft;
    $ch = curl_init();
    $options = array (CURLOPT_RETURNTRANSFER => true, // return web page
        CURLOPT_FAILONERROR => true,
        CURLOPT_URL => $url.$sUrl,
        CURLOPT_HTTPHEADER => $headers,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => $fields_string,
        CURLOPT_HEADER => false,                      // don't return headers
        CURLOPT_SSL_VERIFYPEER => false,              // TODO: fix certificate provider list problem later
        CURLOPT_CONNECTTIMEOUT => 6,                  // timeout on connect
        CURLOPT_TIMEOUT => 10  );                      // timeout on response

    curl_setopt_array ( $ch, $options );
    try {
        $result=curl_exec( $ch );
        $log->LogDebug($result);
        //$header = curl_getinfo ( $ch );
        $err = curl_errno ( $ch );
        $errmsg = curl_error ( $ch );
        curl_close($ch);
        if ($errmsg) throw new Exception($errmsg);
        return $result;
     } catch (Exception $e) {  throw $e;  }

}

paypal的示例發票：

Answer 1

我發現了這個問題：

從paypal的發票文件：

注意：發票中指定的商家必須擁有信譽良好的PayPal帳戶。

顯然，不應使用示例帳戶“dennis@sample.com”。 當我使用自己的沙盒帳戶獲取商家信息時，一切都神奇地起作用了......

也許其他人可能有這個問題，現在解決方案已經發布。 也許我的示例代碼也可能有幫助......

Answer 2

我無法找到顯示在PayPal REST文檔中使用Accept / Accept-Language的示例。

$accept = "Accept:application/json";
$acceptlang = "Accept-Language:en_US";

我會從你的標題中刪除這些，看看這是否會改變你得到的錯誤。
