c# - 远程服务器返回错误: (400) Bad Request when trying execute AddMessageAsync()

Question

我在尝试从另一个项目的 Webjob 中插入消息时遇到 Azure Web job 问题。在 github issues 中没有找到太多帮助。不知道哪里出了问题。我的代码如下:

var queueClient = _storageAccount.CreateCloudQueueClient();
        var queue = queueClient.GetQueueReference("SendReminderEmail");
        var aClassObject = new AModel()
        {
            ObjectName1 = p1,
            ObjectName2 = p2
        };
        var message= new CloudQueueMessage(JsonConvert.SerializeObject(aClassObject ));
        **await queue.AddMessageAsync(message);** error triggers here

消息的json输出:

{"stringKey":"value1","intKey":intValue}

这是队列对象的样子:

这是我拥有的堆栈跟踪:

本质上，问题在于您正在使用的队列名称 ( SendReminderEmail )。它应该全部小写( sendreminderemail )。有关队列命名规则的完整列表，请参阅此链接:https://learn.microsoft.com/en-us/rest/api/storageservices/naming-queues-and-metadata .

此外，我是否建议您通过将消息转换为 Base64 编码字符串来存储消息。我之所以这么说是因为消息正文应该是 XML 安全的。以防万一您的邮件正文包含无效字符，例如 < , > , &等等，您的消息不会被添加到队列中。
