Question

我收到以下错误：

<Type>Sender</Type>
<Code>SignatureDoesNotMatch</Code>
       −
<Message>
The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.
</Message>

尝试按照http://docs.developer.amazonservices.com/en_US/auth_token/AuthToken_GetAuthToken.html

上的文档进行GetAuthData调用

按照http://docs.developer.amazonservices.com/en_US/dev_guide/DG_ClientLibraries.html#DG_OwnClientLibrary__Signatures计算签名。

Answer 1

以下是我能够做到的工作：

修改http://docs.developer.amazonservices.com/en_US/dev_guide/DG_ClientLibraries.html#DG_OwnClientLibrary__Signatures中的calculateStringToSignV2（）方法以包含网址的尾随部分

    Map<String, String> sorted = new TreeMap<String, String>();
sorted.putAll(parameters);

// Set endpoint value
URI endpoint = new URI(serviceUrl.toLowerCase());

// Create flattened (String) representation
StringBuilder data = new StringBuilder();
data.append("POST\n");
data.append(endpoint.getHost());
data.append("\n/Sellers/2011-07-01"); //YOUR URL
data.append("\n");

Iterator<Map.Entry<String, String>> pairs =
        sorted.entrySet().iterator();
while (pairs.hasNext()) {
    Map.Entry<String, String> pair = pairs.next();
    if (pair.getValue() != null) {
        data.append( pair.getKey() + "=" + pair.getValue());
    }
    else {
        data.append( pair.getKey() + "=");
    }

    // Delimit parameters with ampersand (&)
    if (pairs.hasNext()) {
        data.append( "&");
    }
}

return data.toString();
}

修改parameters.put（“Timestamp”，urlEncode（“2013-05-02T16：00：00Z”））;在文档http://docs.developer.amazonservices.com/en_US/dev_guide/DG_ClientLibraries.html#DG_OwnClientLibrary__Signatures中，以便timestamp参数为UTC和ISO-8601

如下所示：

String dt = DateTime.now(DateTimeZone.UTC).toString(DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss'Z"));

parameters.put("Timestamp", urlEncode(dt));

P.S。我花了5-6个小时调试这个问题，并没有通过谷歌找到任何解决方案，所以最好把它放在这里以节省其他人的时间。
