我创建了一个简单的控制台应用程序并将其作为Azure webjob运行,得到以下错误。相同的代码在本地工作正常。

控制台应用代码:

class Program

    static void Main(string[] args)
    {
        getStockPriceFromGoogle();

    public static void getStockPriceFromGoogle()

            CloudTable googleStockTable = tableClient.GetTableReference("GoogleStock");
            googleStockTable.CreateIfNotExists();

            const string tickers = "RELIANCE,SBIN";
            string json = null;

            {
                Trace.WriteLine("Error calling Google service , error :" + ex.ToString());
            }

            //Google adds a comment before the json for some unknown reason, so we need to remove it
            json = json.Replace("//", "");

            var v = JArray.Parse(json);

            foreach (var i in v)
            {
                var ticker = i.SelectToken("t");
                var price = (decimal)i.SelectToken("l");

                GoogleStock googleStock = new GoogleStock(ticker.ToString(), DateTime.Now)
                {
                    Price = price,
                    PriceInLocalCurrency = i.SelectToken("l_cur").ToString(),

                };

                try

                Console.WriteLine($"{ticker} : {price}");
            }

class GoogleStock : TableEntity
{
    public GoogleStock(string StockName, DateTime InsertionDate)
    {
        this.PartitionKey = StockName;
        this.RowKey = InsertionDate.ToUniversalTime().ToString();
    }

    public int id { get; set; }

    public string StockName { get; set; }

    public string Exchange { get; set; }

    public decimal Price { get; set; }

    public string PriceInLocalCurrency { get; set; }

    public DateTime LastTradeTime { get; set; }

    public float Chanage { get; set; }

    public float ChnagePersontage { get; set; }
}

我在azure portal中添加了app设置键,但仍然没有帮助。

当我们对Table服务执行操作时,许多factors可能会导致400错误的请求错误。例如,属性名称无效,指定的值无效等。

  

相同的代码在本地工作正常。

我在我的本地测试你的代码,你的代码不起作用(它返回400错误的请求错误)在我的本地。我发现您使用基于日期时间的行键(this.RowKey = InsertionDate.ToUniversalTime().ToString();),这可能会导致此类型问题。行键值在我的本地显示为 10/11/2016 3:14:03 AM (具有正斜杠(/)字符)。但是,PartitionKey和RowKey属性的值中不允许使用正斜杠(/)字符。请查看“Characters Disallowed in Key Fields”部分。

您可以尝试使用以下代码将Ticks中的当前时间值作为行键值。

this.RowKey = InsertionDate.Ticks.ToString("d19");

此外,您可以查看this article,其中介绍了根据日期时间生成分区键的两种方法。
