向ebay API发送JSON请求

Question

string jsonInventoryRequest = "{" +
                    "\"requests\": [";

        int commaCount = 1;
        foreach (var ep in productsToProcess)
        {
            jsonInventoryRequest += "{\"offers\": [{" +
                "\"availableQuantity\":" + ep.EbayProductStockQuantity + "," +
                "\"offerId\":\"" + ep.EbayID.ToString() + "\"," +
                "\"price\": {" +
                    "\"currency\": \"AUD\"," +
                    "\"value\":\"" + ep.EbayProductPrice.ToString() + "\"" +
                "}" +
            "}],";

            jsonInventoryRequest += "\"shipToLocationAvailability\": " + "{" +
                "\"quantity\":" + ep.EbayProductStockQuantity +

            jsonInventoryRequest += "\"sku\": " + ep.EbayProductSKU.ToString() + "}";
            if (commaCount < productsToProcess.Count())
                jsonInventoryRequest += ",";

            commaCount++;
            sendEbayApiRequest = true;
        }

        jsonInventoryRequest += 
            "]" +
        "}";

json string = {"requests": [{"offers": [{"availableQuantity":0,"offerId":"098772298312","price": {"currency": "AUD","value":"148.39"}}],"shipToLocationAvailability": {"quantity":0},"sku": 135779},{"offers": [{"availableQuantity":1,"offerId":"044211823133","price": {"currency": "AUD","value":"148.39"}}],"shipToLocationAvailability": {"quantity":1},"sku": 133607}]}

var ebayAppIdSetting = _settingService.GetSettingByKey(

                            "ebaysetting.appid", "");

        var stringToEncode = ebayAppIdSetting + ":" + ebayCertIdSetting;

        HttpClient client = new HttpClient();
        byte[] bytes = Encoding.UTF8.GetBytes(stringToEncode);
        var base64string = "Basic " + System.Convert.ToBase64String(bytes);

        var stringContent = "?grant_type=client_credentials&" + "redirect_uri=" + ebayRuNameSetting + "&scope=https://api.sandbox.ebay.com/oauth/api_scope";
        var requestBody = new StringContent(stringContent.ToString(), Encoding.UTF8, "application/json");
        requestBody.Headers.ContentType = new MediaTypeHeaderValue("application/x-www-form-urlencoded");
        var response = client.PostAsync("https://api.sandbox.ebay.com/identity/v1/oauth2/token", requestBody);

有人能看出我哪里出了问题吗。干杯

Answer 1

好的，所以身份验证失败是因为我发送了错误的身份验证令牌。需要从应用程序令牌中获取oauth令牌。

因此，与base64编码标记不同，如下所示：

var base64string = "Basic " + System.Convert.ToBase64String(bytes);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", base64string);

我需要做以下几点：

url = "https://api.sandbox.ebay.com/sell/inventory/v1/bulk_update_price_quantity";
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

        request.Method = "POST";
        //request.ContentType = "application/json; charset=utf-8";
        request.Headers.Add("Authorization", "Bearer **OAUTH TOKEN GOES HERE WITHOUT ASTERIKS**");

        // Send the request
        using (var streamWriter = new StreamWriter(request.GetRequestStream()))
        {
            streamWriter.Write(jsonInventoryRequest);
            streamWriter.Flush();
            streamWriter.Close();
        }

        // Get the response
        HttpWebResponse response = (HttpWebResponse) request.GetResponse();
        if (response != null)
        {
            using (var streamReader = new StreamReader(response.GetResponseStream()))
            {
                // Parse the JSON response
                var result = streamReader.ReadToEnd();
            }
        }
