错误414使用_UPLOAD_VAT_INVOICE_将发票发送到Amazon MWS时，错误>

Question

我正在按照本指南中的Java示例，通过_UPLOAD_VAT_INVOICE_将发票发送给亚马逊MWS：Link

pdf文件是85 kb的简单发票错误是状态代码414，它是“ Uri太长”]

调试原始的亚马逊类MarketplaceWebServiceClient，我看到了：

    if( request instanceof SubmitFeedRequest ) {

    // For SubmitFeed, HTTP body is reserved for the Feed Content and the function parameters 
    // are contained within the HTTP header
    SubmitFeedRequest sfr = (SubmitFeedRequest)request;

    method = new HttpPost( config.getServiceURL() + "?" + getSubmitFeedUrlParameters( parameters ) );

getSubmitFeedUrlParameters方法获取每个参数，并将其添加到querystring。这些参数之一是来自以下位置的contentMD5：字符串contentMD5 = Base64.encodeBase64String（pdfDocument）;因此，有一个很大的字符串表示作为参数传递的pdf文件。这导致错误414

但是该类是来自MaWSJavaClientLibrary-1.1.jar的原始类。>

有人可以帮我吗？

谢谢

InputStream contentStream = new ByteArrayInputStream(pdfDocument);
String contentMD5 =computeContentMD5Header(new ByteArrayInputStream(pdfDocument));

public static String computeContentMD5Header(InputStream inputStream) {

        // Consume the stream to compute the MD5 as a side effect.
        DigestInputStream s;
        try {
            s = new DigestInputStream(inputStream,
                    MessageDigest.getInstance("MD5"));

            // drain the buffer, as the digest is computed as a side-effect
            byte[] buffer = new byte[8192];
            while (s.read(buffer) > 0)
                ;

            return new String(

            org.apache.commons.codec.binary.Base64.encodeBase64(s
                    .getMessageDigest().digest()), "UTF-8");
        } catch (NoSuchAlgorithmException e) {
            throw new RuntimeException(e);
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }
