GetLowestPricedOffersForSKU失敗處理參數

我試圖調用GetLowestPricedOffersForSKU時有輕微的問題，我得到的迴應：GetLowestPricedOffersForSKU失敗處理參數

Failed processing arguments of org.jboss.resteasy.spi.metadata

我可以調用其他函數在產品阿比他們的工作很好，只是得到上面的錯誤這個功能。

我已經找到了答案的網絡，但找不到與此有關的任何內容，有沒有人有任何想法，爲什麼我得到這個？

順便說一下，它在MWS Scratchpad中一切正常！

使用哪個客戶端庫？ –

嗨保羅，感謝您的信息，我會給它一個去看看會發生什麼。 – Potman100

發佈以防其他人遇到此問題，並且與我一樣困惑。除了這個特殊的亞馬遜MWS請求外，幾乎所有的亞馬遜MWS請求都有一個基本的區別。所有其他請求在技術上接受參數作爲查詢參數而不是POST數據。暫存器甚至表明這是實際工作方式（儘管MWS Scratchpad實際上也將數據作爲後期數據字段發送）。

以及這個如何表現？ – YakovL

MWS需要將POST數據作爲表單參數傳遞，而不是作爲某些操作的查詢字符串傳遞。否則，它會爲此類操作（GetMyFeesEstimate是另一種受此影響的操作）錯誤風格400 Bad Request錯誤。

舉例來說，如果你在狂飲6做了以下POST請求那麼你很可能得到錯誤：

$response = $client->request('POST', 'https://mws.amazonservices.com/Products/2011-10-01/?AWSAccessKeyId=YOURAWSACCESSKEY&Action=GetLowestPricedOffersForASIN&SellerId=YOURSELLERID&MWSAuthToken=amzn.mws.fghsffg-4t44e-hfgh-dfgd-zgsdbfe5erg&SignatureVersion=2&Timestamp=2017-07-09T15%3A45%3A18%2B00%3A00&Version=2011-10-01&Signature=bCasdxXmYDCasdaXBhsdgse4pQ6hEbevML%2FJvzdgdsfdy2o%3D&SignatureMethod=HmacSHA256&MarketplaceId=ATVPDKIKX0DER&ASIN=B007EZK19E');

爲了解決這個問題，你會提交的表單數據，在此Guzzle 6例如：

$response = $client->request('POST', 'https://mws.amazonservices.com/Products/2011-10-01', [ 
    'form_params' => [ 
     'AWSAccessKeyId' => 'YOURAWSACCESSKEY', 
     'Action' => 'GetLowestPricedOffersForASIN', 
     'SellerId' => 'YOURSELLERID', 
     'MWSAuthToken' => 'amzn.mws.fghsffg-4t44e-hfgh-dfgd-zgsdbfe5erg', 
     'SignatureVersion' => 2, 
     'Timestamp' => '2017-07-09T15%3A45%3A18%2B00%3A00', 
     'Version' => '2011-10-01', 
     'Signature' => 'bCasdxXmYDCasdaXBhsdgse4pQ6hEbevML%2FJvzdgdsfdy2o%3D', 
     'SignatureMethod' => 'HmacSHA256', 
     'MarketplaceId' => 'ATVPDKIKX0DER', 
     'ASIN' => 'B007EZK19E', 
    ] 
]);
