Question

尝试Azure中的一些新功能; Azure函数运行Powershell。有一件事我挣扎了一段时间：我无法以普通的JSON获得输出，而是看似格式化并包含转义字符并且混乱了双引号。

function.json：

{
  "bindings": [
    {
      "name": "req",
      "type": "httpTrigger",
      "direction": "in",
      "webHookType": "genericJson",
      "methods": [
        "post",
        "head",
        "trace"
      ]
    },
    {
      "name": "res",
      "type": "http",
      "direction": "out"
    }
  ],
  "disabled": false
}

run.ps1：

$ApiURI="http://avwx.rest/api/metar.php?station=ymml&format=JSON"
$Result = Invoke-RestMethod -Uri $ApiURI
Out-File -Encoding Ascii -FilePath $res -inputObject $Result

以下回复的结果：

"\r\n\r\nAltimeter         : 1015\r\nCloud-List        : {FEW 035}\r\nDewpoint          : 11\r\nFlight-Rules      : VFR\r\nOther-List        : {}\r\nRaw-Report        : YMML 210900Z 17010KT 9999 FEW035 19/11 Q1015 NOSIG\r\nRemarks           : NOSIG\r\nRemarks-Info      : \r\nRunway-Vis-List   : {}\r\nStation           : YMML\r\nTemperature       : 19\r\nTime              : 210900Z\r\nUnits             : @{Altimeter=hPa; Altitude=ft; Temperature=C; Visibility=m; \r\n                    Wind-Speed=kt}\r\nVisibility        : 9999\r\nWind-Direction    : 170\r\nWind-Gust         : \r\nWind-Speed        : 10\r\nWind-Variable-Dir : {}\r\n\r\n\r\n\r\n"

但我期望的是：

{
  "Altimeter": "1016", 
  "Cloud-List": [], 
  "Dewpoint": "12", 
  "Flight-Rules": "VFR", 
  "Other-List": [], 
  "Raw-Report": "YMML 210930Z 17011KT CAVOK 18/12 Q1016 NOSIG", 
  "Remarks": "NOSIG", 
  "Remarks-Info": {}, 
  "Runway-Vis-List": [], 
  "Station": "YMML", 
  "Temperature": "18", 
  "Time": "210930Z", 
  "Units": {
    "Altimeter": "hPa", 
    "Altitude": "ft", 
    "Temperature": "C", 
    "Visibility": "m", 
    "Wind-Speed": "kt"
  }, 
  "Visibility": "9999", 
  "Wind-Direction": "170", 
  "Wind-Gust": "", 
  "Wind-Speed": "11", 
  "Wind-Variable-Dir": []
}

这里可能有什么问题？

Answer 1

我不确定你是如何得到这个结果的，因为Invoke-RestMethod将数据存储在ResponseData属性中。当您使用Invoke-RestMethod时，它会将json数据转换为Powershell对象。在run.ps1中，您似乎要将PS对象保存到文件中，而不是JSON数据。

如果您不打算修改JSON数据，将它转换为PSObject真的没用。所以你可以改用Invoke-webrequest。

但是如果你想修改它。

$uri = "http://avwx.rest/api/metar.php?station=ymml&format=JSON"

$request = Invoke-RestMethod -Uri $uri

#Get the result and convert it back to JSON
$Result = $request.responseData | ConvertTo-Json
$Result | Out-File .\data.json -Encoding Ascii

@David - 是的，以下适用于Azure功能。

一个。 run.ps1文件内容

$ApiURI="http://avwx.rest/api/metar.php?station=ymml&format=JSON"
$Result = Invoke-RestMethod -Uri $ApiURI | ConvertTo-Json
Out-File -Encoding Ascii -FilePath $res -inputObject $Result

湾在Azure Functions Portal和Postman中请求结果。

{
  "Altimeter": "1016",
  "Cloud-List": [
    [
      "FEW",
      "016"
    ]
  ],
  "Dewpoint": "13",
  "Flight-Rules": "VFR",
  "Other-List": [],
  "Raw-Report": "YMML 212100Z 28005KT 9999 FEW016 15/13 Q1016 NOSIG",
  "Remarks": "NOSIG",
  "Remarks-Info": {},
  "Runway-Vis-List": [],
  "Station": "YMML",
  "Temperature": "15",
  "Time": "212100Z",
  "Units": {
    "Altimeter": "hPa",
    "Altitude": "ft",
    "Temperature": "C",
    "Visibility": "m",
    "Wind-Speed": "kt"

  "Visibility": "9999",
