代碼是
var ProductAdvertisingAPIv1 = require('./src/index');
var defaultClient = ProductAdvertisingAPIv1.ApiClient.instance;
defaultClient.accessKey = 'accessKey';
defaultClient.secretKey = 'secretKey';
defaultClient.host = 'webservices.amazon.com';
defaultClient.region = 'us-east-1';
var api = new ProductAdvertisingAPIv1.DefaultApi();
var getItemsRequest = new ProductAdvertisingAPIv1.GetItemsRequest();
getItemsRequest['PartnerTag'] = 'raassnacbt-21';
getItemsRequest['PartnerType'] = 'Associates';
getItemsRequest['ItemIds'] = ['B075LRK2QK'];
getItemsRequest['Condition'] = 'New';
getItemsRequest['Resources'] = ['Images.Primary.Medium', 'ItemInfo.Title', 'Offers.Listings.Price'];
function parseResponse(itemsResponseList) {
var mappedResponse = {};
for (var i in itemsResponseList) {
mappedResponse[itemsResponseList[i]['ASIN']] = itemsResponseList[i];
}
return mappedResponse;
}
try {
api.getItems(getItemsRequest, callback);
} catch (ex) {
console.log("Exception: " + ex);
}
即使只發出一個請求,我也會收到“太多請求”錯誤。 還嘗試在服務器上運行它,以防萬一它與本地主機有關。 沒有手動修改,它只是帶有我的憑據的 sdk 代碼。 知道可能是什么問題嗎?
這是人們在使用亞馬遜產品 API 時面臨的一個非常普遍的問題。 亞馬遜采用了一種非常不同的算法。 它根據您通過亞馬遜賺取的佣金分配 API 閾值/使用限制。 一旦您分配的限制用完,您將收到此類錯誤。 要解決此問題,請讓您的朋友通過您的會員鏈接購買。 你會得到一些門檻。
老話題,但也許有用。 我意識到身份驗證失敗時也會顯示此錯誤。 因此,有必要考慮到關聯 ID 僅在特定區域中處於活動狀態,並且新生成的 API 密鑰可能需要 72 小時才能真正處於活動狀態,因此除了其他用戶提到的配額內容之外,如有必要,請檢查這些點。
