问题描述
我正在尝试使用 SP-API 更新我的库存 Amazon Catalog 的库存。 这是我的代码：
private static IRestRequest CreateRequestFeedDocument()
{
IRestRequest restRequest = new RestRequest("Feeds/2020-09-04/documents",Method.POST);
AmazonInventory obj = new AmazonInventory();
obj.SKU = "GD4297-44";
obj.Available = "true";
obj.Quantity = "20";
string xml = string.Empty;
using (var stringwriter = new System.IO.StringWriter())
{
var serializer = new XmlSerializer(obj.GetType());
serializer.Serialize(stringwriter,obj);
xml = stringwriter.ToString();
}
restRequest.AddParameter("contentType",xml,ParameterType.RequestBody);
restRequest.AddQueryParameter("MarketplaceIds","APJ6JRA9NG5V4,A1PA6795UKMFR9,A13V1IB3VIYZZH,A1805IZSGTT6HS,A1F83G8C2ARO7P,A1RKKUPIHCS9HS,A2NODRKZP88ZB9");
AssumeRoleResponse assumeRoleResponse = null;
Task.Run(async () =>
{
assumeRoleResponse = await GetAssumeRoletokenDetail();
}).GetAwaiter().GetResult();
// LWA credentials for app in amazon seller central
var clientId = AmazonCredentials.Default.ClientId;
var clientSecret = AmazonCredentials.Default.ClientSecret;
// generate refresh token with 'Authorize' action for app in amazon seller central
var refreshToken = AmazonCredentials.Default.RefreshToken;
var lwaAuthCreds = new LWAAuthorizationCredentials
{
ClientId = clientId,ClientSecret = clientSecret,RefreshToken = refreshToken,Endpoint = new Uri("https://api.amazon.com/auth/o2/token")
};
restRequest = new LWAAuthorizationSigner(lwaAuthCreds).Sign(restRequest);
var awsAuthCreds = new AWSAuthenticationCredentials
{
AccessKeyId = assumeRoleResponse.Credentials.AccessKeyId,SecretKey = assumeRoleResponse.Credentials.SecretAccessKey,Region = AmazonCredentials.Default.Region
};
restRequest.AddHeader("x-amz-security-token",assumeRoleResponse.Credentials.SessionToken);
restRequest = new AWSsigv4Signer(awsAuthCreds)
.Sign(restRequest,restClient.BaseUrl.Host);
return restRequest;
}
restClient = new RestClient(live_url_base);
IRestRequest restRequest = CreateRequestFeedDocument();
var response = restClient.Execute(restRequest);
我收到以下错误
{
"errors": [
{
"code": "InvalidInput","message": "Invalid Input","details": ""
}
]
}
我在网上找到了这个解决方案
添加这一行：
restRequest.AddJsonBody(new { contentType = "text/xml; charset=UTF-8" });
我没有收到 Invalid inout 错误，但我收到了
<Message>The request signature we calculated does not match the signature you provided. Check your key and signing method.</Message>

我错在哪里？
