好的，所以我在将这些JSON请求发送到Ebay API时遇到了一些麻烦。

这是json请求：

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 += 
            "]" +
        "}";

上述JSON请求的Debug.WriteLine()输出为：

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}]}

以下是C＃中发送请求的代码：

var ebayAppIdSetting = _settingService.GetSettingByKey(
                            "ebaysetting.appid", "");

        var ebayCertIdSetting = _settingService.GetSettingByKey(
                            "ebaysetting.certid", "");

        var ebayRuNameSetting = _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);
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", base64string);

        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);

我Debug.WriteLine("response.Content = " + response.Result);时得到的输出是：

response.Content = StatusCode：401，ReasonPhrase：'Unauthorized'，   版本：1.1，内容：System.Net.Http.StreamContent，Headers：{

任何人都可以看到我出错的地方。干杯

好的，因此身份验证失败了，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。

所以不是像这样的base64编码令牌：

__set__

我需要做以下事情：

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

向ebay API
