来自 JSON 的 T-SQL Select 返回 JSON 文本格式不正确

Question

Using a stored procedure in SQL Server 2016 (included below) I need to make a select from the nested JSON output from a remote file, but at my initial SELECT * I already have issues since the server returns that the JSON text is not properly formatted ：

JSON 文本格式不正确。 在 position 0 处发现意外字符“A”。

我使用的 T-SQL 脚本：

CREATE PROCEDURE wget 
    @url VARCHAR(255), 
    @payload NVARCHAR(max) OUTPUT
AS
BEGIN
    DECLARE @op TABLE (op nvarchar(max))
    DECLARE @c varchar(1000) = N'powershell.exe -noprofile -executionpolicy bypass'
    + N'-command (Invoke-WebRequest -Uri "'+@url+'" -UseBasicParsing).content'

    INSERT INTO @op 
        EXEC xp_cmdshell @c

    SELECT @payload = STRING_AGG(op, '') 
    FROM @op
END


DECLARE @jsn nvarchar(max)
EXEC wget @url = 'https://<URL-WITH-JSON-DATA>',
          @payload = @jsn output

SELECT * 
FROM OPENJSON (@jsn, N'$')

JSON 文件的 2 个数组示例：

[
    {
      "Localnumber":"2931",
      "Name":"Some Name",
      "Description":null,
      "Email":"mail@domain.dk",

谁能指出我正确的方向？

解决方案是将 JSON 从 JScript 服务器端导入带有 varchar(MAX) 的表中：

Response.CacheControl = "no-cache"
Response.Expires = -1
Response.CodePage = 65001
Response.CharSet = "UTF-8"

var objSrvHTTP;
objSrvHTTP = Server.CreateObject ("Msxml2.ServerXMLHTTP.6.0");
objSrvHTTP.open ("GET","<%URL_TO_JSON_DATA%>", false);
objSrvHTTP.send ();
Response.ContentType = "application/json";

然后使用以下查询从表中查询存储的 JSON：

DECLARE @json NVARCHAR(MAX)
SET @json = (SELECT PHONE_DATA FROM EFP_JSON WHERE ID = 1)

SELECT PhoneNumber
FROM EFP_PhoneNumberSeries
WHERE REPLACE(PhoneNumber, ' ', '') NOT IN (
    SELECT PhoneNumbers.Number
    FROM OPENJSON(@json)
    WITH (   
        Localnumber VARCHAR(50) '$.Localnumber',
        Name VARCHAR(50) '$.Name',
        Email VARCHAR(50) '$.Email',
        PhoneNumbers nvarchar(max) '$.PhoneNumbers' AS JSON,
        Phones nvarchar(max) '$.Phones' AS JSON       
        ) as UserInfo
    CROSS APPLY OPENJSON(PhoneNumbers)
    WITH(
        Number nvarchar(100) '$.Number',
        LineName nvarchar(100) '$.LineName',
        GotoLocalNumber nvarchar(100) '$.GotoLocalNumber',
        BelongsTo nvarchar(100) '$.BelongsTo'
        )  as PhoneNumbers
    CROSS APPLY OPENJSON(Phones)
    WITH(
        description nvarchar(100) '$.description'
        ) as description
    ) 
AND REPLACE(PhoneNumber, ' ', '') NOT IN ('12345678','98765432')
AND (REPLACE(PhoneNumber, ' ', '') LIKE '1234%' OR REPLACE(PhoneNumber, ' ', '') LIKE '98765%');
