问题描述

我正在使用逻辑应用程序在存储之前转换我的数据。为此,我使用 json 到 json 内置转换器,它使用液体。这是我的原始输入,

{  
   "type":"FeatureCollection",
   "metadata":{  
      "generated":1539147197000,
      "url":"https://earthquake.usgs.gov/fdsnws/event/1/query?format=geojson&starttime=2018-10-09T04:53:16.6743076Z",
      "title":"USGS Earthquakes",
      "status":200,
      "api":"1.5.8",
      "count":245
   },
   "features":[  
      {  
         "type":"Feature",
         "properties":{  
            "mag":1.9,
            "place":"118km NNW of Arctic Village, Alaska",
            "time":1539146474786,
            "updated":1539146692433,
            "tz":-540,
            "url":"https://earthquake.usgs.gov/earthquakes/eventpage/ak20275217",
            "detail":"https://earthquake.usgs.gov/fdsnws/event/1/query?eventid=ak20275217&format=geojson",
            "felt":null,
            "cdi":null,
            "mmi":null,
            "alert":null,
            "status":"automatic",
            "tsunami":0,
            "sig":56,
            "net":"ak",
            "code":"20275217",
            "ids":",ak20275217,",
            "sources":",ak,",
            "types":",geoserve,origin,",
            "nst":null,
            "dmin":null,
            "rms":1.17,
            "gap":null,
            "magType":"ml",
            "type":"earthquake",
            "title":"M 1.9 - 118km NNW of Arctic Village, Alaska"
         },
         "geometry":{  
            "type":"Point",
            "coordinates":[  
               -146.6925,
               69.1011,
               0
            ]
         },
         "id":"ak20275217"
      },
...(list continues)

这是我在逻辑应用程序中映射的液体文件,

{
    "Data": [
        {% for f in content.features %}
        {
            "type": "{{f.properties.type}}",
            "mag": {{f.properties.mag}},
            "place": "{{f.properties.place}}",
            "time": "{{f.properties.time}}",
            "tsunami": {{f.properties.tsunami}},
            "code": "{{f.properties.code}}",
            "ids": "{{f.properties.ids}}",
            "magType": "{{f.properties.magType}}",
            "source": "{{f.properties.sources}}",
            "longitude": {{f.geometry.coordinates[0]}},
            "latitude": {{f.geometry.coordinates[1]}}
        },
        {% endfor %}
    ]
}

它实际上提供了所需的输出,但对于时间字段,它只是给出了一个错误,如下所示,

"time": "液体错误:值对于 Int32 来说太大或太小。",

我尝试使用本指南将此字段转换为字符串,

但是似乎没有任何效果,并且它给出了类型转换错误。我只想将时间值按原样(甚至作为字符串)保存在原始输入文件中,这是一个 Unix 纪元时间戳。
谢谢

解决方案


尝试追加:'' | f.时间

关键是首先将其强制为字符串。
