Mongo LiveCode MergJSON无法解码文档

哈维尔

返回有关Mongo和LiveCode的更多问题,这一次是针对MergJSON的问题。

就是这种情况:在以前的帖子中,我问了一些有关如何连接查询并从查询中获得结果的问题,这些问题在哪里得到了回答。

现在,我在LiveCode字段中从Mongo返回了文档(用于验证)。

这是返回的文件:

    { "_id" : "001003", "nombre" : "Pedro" }
    { "_id" : "001004", "nombre" : "Alejandro" }
    { "_id" : "001005", "nombre" : "Mario" }
    { "_id" : "001001", "nombre" : "Javier" }
    { "_id" : "001002", "nombre" : "Andrecillo" }

我现在想要的是无法完成的工作,我的堆栈有一个按钮脚本,我有一个mouseup处理程序:

on mouseUp
    local dbText, dbResultado
    set the hideConsoleWindows to true
    put "var c=db.nueva.find();" into dbText
    put " while(c.hasNext())" after dbText
    put " printjson(c.next())" after dbText
    put shell("C:\mongodb\bin\mongo.exe --eval" && quote & dbText & quote) into dbResultado
    put line 3 to -1  of dbResultado into pJSON
    put  pJSON  into  field "A"  -- just to see what Mongo is returning after eliminating       line 1 and 2 of dbResultado
    put JSONToArray(pJSON) into tArray
    put tArray["nombre"] into fld "B"
end mouseUp

此处理程序之后是Decode和Encode函数。

运行此脚本时,出现错误:

     executing at 10:15:18 AM
     Type   could not decode JSON: end of file expected near '{'
     Object Mejoraddo
     Line   repeat for each line tKey in mergJSONDecode(pJSON,"tArray")
     Hint   could not decode JSON: end of file expected near '{'

在此函数JSONToArray pJSON中:

     repeat for each line tKey in mergJSONDecode(pJSON,"tArray")

我几乎可以肯定,我缺少一个简单的步骤或监督了一些显而易见的事情。请,如果您需要一些说明,我会尽力向您解释,谢谢,

不是JSON:

{ "_id" : "001003", "nombre" : "Pedro" }
{ "_id" : "001004", "nombre" : "Alejandro" }
{ "_id" : "001005", "nombre" : "Mario" }
{ "_id" : "001001", "nombre" : "Javier" }
{ "_id" : "001002", "nombre" : "Andrecillo" }

JSON:

[
  { "_id" : "001003", "nombre" : "Pedro" },
  { "_id" : "001004", "nombre" : "Alejandro" },
  { "_id" : "001005", "nombre" : "Mario" },
  { "_id" : "001001", "nombre" : "Javier" },
  { "_id" : "001002", "nombre" : "Andrecillo" }
]

请参阅JSON文档

尝试:

local tIndex = 1
repeat for each line tJSON in line 3 to -1  of dbResultado
    put JSONToArray(tJSON) into tArray[tIndex]
    add 1 to tIndex
end repeat
put tArray[1]["nombre"] into fld "B"
