JSON 从 Particle Photon Webhook 格式化到 Azure

Question

我连接了我的 Particle Photon 来记录我的温度，然后将事件发布到 Microsoft Azure 的 eventhub。然后我使用 Stream Analytics 将 JSON 文件输出到 Azure 存储中（好主意？还是不好？）。

当我尝试通过 HTML 使用 <script src="URL"></script> 打开它时，我在浏览器控制台中得到 " 未捕获的语法错误：意外标记：" window。我还尝试使用 JSON 格式化程序验证我的 JSON 文件，但出现了很多错误。

这是 JSON 文件：https://pptlbhstorage.blob.core.windows.net/temperature/0_d1e8a2b709b14461b5ac12265f33020b_1.json

根据流分析，我使用此查询创建了一个作业：

CREATE TABLE pptlbhhub (
  coreid nvarchar(max),
  data nvarchar(max),
  event nvarchar(max),
  EventEnqueuedUtcTime datetime,
  EventProcessedUtcTime datetime,  
  measurename nvarchar(max),
  PartitionId bigint,
  published_at datetime,
  subject nvarchar(max),
  timecreated datetime,
  unitofmeasure nvarchar(max),
  value float
);

SELECT
   coreid
  ,event
  ,EventEnqueuedUtcTime
  ,EventProcessedUtcTime
  ,measurename
  ,PartitionId
  ,published_at
  ,subject
  ,timecreated
  ,unitofmeasure
  ,value
INTO
    pptlbhstorage
FROM
    pptlbhhub;

Answer 1

如果您将事件输出为数组，您的 JSON 文件就可以了： [{}, {}, ...] 代替 {} {} {} ...

Answer 2

我的意思是您的文件应该看起来像这样 JSON 有效（就像一个数组）。 [{"coreid":"1e0041000c47343432313031","displayname":"IoT Assignment 3","event":"PublishToEventHub","eventenqueuedutctime":"2016-05-12T08:56:20.5300000Z","eventprocessedutctime":"2016-05-12T08:56:21.3068971Z","guid":"1e0041000c47343432313031","location": "Oslo","measurename":"Temperature","organization":"Westerdals ACT","partitionid":0,"published_at":"2016-05-12T08 :56:21.0850000Z","subject":"Weather","timecreated":"2016-05-12T08:56:21.0850000Z","unitofmeasure":"F", "value":21.0}, {"coreid":"1e0041000c47343432313031","displayname":"IoT Assignment 3","event":"PublishToEventHub","eventenqueuedutctime":"2016-05-12T08:56: 20.5300000Z","eventprocessedutctime":"2016-05-12T08:56:21.3068971Z","guid":"1e0041000c47343432313031","location":"Oslo","measurename" :"Temperature","organization":"Westerdals ACT","partitionid":0,"published_at":"2016-05-12T08:56:21.0850000Z","subject":"Weather","timecreated":"2016-05-12T08:56:21.0850000Z","unitofmeasure":"F","value":21.0}, ...]

不喜欢 {"coreid":"1e0041000c47343432313031","displayname":"IoT Assignment 3","event":"PublishToEventHub","eventenqueuedutctime":"2016-05-12T08:56: 20.5300000Z","eventprocessedutctime":"2016-05-12T08:56:21.3068971Z","guid":"1e0041000c47343432313031","location":"Oslo","measurename" :"Temperature","organization":"Westerdals ACT","partitionid":0,"published_at":"2016-05-12T08:56:21.0850000Z","subject":"Weather","timecreated":"2016-05-12T08:56:21.0850000Z","unitofmeasure":"F","value":21.0} {"coreid":"1e0041000c47343432313031","displayname":"IoT Assignment 3","event":"PublishToEventHub","eventenqueuedutctime":"2016-05-12T08:56: 20.5300000Z","eventprocessedutctime":"2016-05-12T08:56:21.3068971Z","guid":"1e0041000c47343432313031","location":"Oslo","measurename" :"Temperature","organization":"Westerdals ACT","partitionid":0,"published_at":"2016-05-12T08:56:21.0850000Z","subject":"Weather","timecreated":"2016-05-12T08:56:21.0850000Z","unitofmeasure":"F","value":21.0}...

区别在于流首&末尾的“[]”和每个元素之间的“,”
