将String转换为JSON node.js

Question

Very new to node.js, I have string returning from RPGLE (as400) program, I would like to return as JSON example below.

String

{orderid:996553,workorder:996553.010,shipped:000000001,received:000000001,status:GOOD},
{orderid:996554,workorder:996554.010,shipped:000000001,received:000000001,status:GOOD},
{orderid:999290,workorder:999290.010,shipped:000000001,received:000000001,status:GOOD},
{orderid:999290,workorder:999290.020,shipped:000000001,received:000000001,status:GOOD},
{orderid:999290,workorder:999290.030,shipped:000000001,received:000000001,status:GOOD},
{orderid:999290,workorder:999290.040,shipped:000000001,received:000000001,status:GOOD},
{orderid:999290,workorder:999290.050,shipped:000000001,received:000000001,status:GOOD},

Would like to convert as below and send to application api

[{"orderid":144234,"workorder":"996553.010","shipped":1,"received":1,"status":"GOOD"},
{"orderid":999290,"workorder":"996553.010","shipped":1,"received":1,"status":"GOOD"},
{"orderid":999290,"workorder":"999290.010","shipped":1,"received":1,"status":"GOOD"},
{"orderid":999290,"workorder":"999290.020","shipped":1,"received":1,"status":"BAD"},
{"orderid":999290,"workorder":"999290.030","shipped":1,"received":1,"status":"GOOD"},
{"orderid":999290,"workorder":"999290.040","shipped":1,"received":1,"status":"GOOD"},
{"orderid":999290,"workorder":"999290.050","shipped":1,"received":1,"status":"GOOD"}]

What would be the best practice and how?

Answer 1

You could parse the lines into valid javascript objects and then stringify them into JSON like this:

 const s = ` {orderid:996553,workorder:996553.010,shipped:000000001,received:000000001,status:GOOD}, {orderid:996554,workorder:996554.010,shipped:000000001,received:000000001,status:GOOD}, {orderid:999290,workorder:999290.010,shipped:000000001,received:000000001,status:GOOD}, {orderid:999290,workorder:999290.020,shipped:000000001,received:000000001,status:GOOD}, {orderid:999290,workorder:999290.030,shipped:000000001,received:000000001,status:GOOD}, {orderid:999290,workorder:999290.040,shipped:000000001,received:000000001,status:GOOD}, {orderid:999290,workorder:999290.050,shipped:000000001,received:000000001,status:GOOD}, `; const array = s.trim().split("\\n").map((line) => line .slice(1, -2) // remove brackets and comma .split(",") // break into individual key/value pairs .map((pair) => pair.split(":")) // split key/value pairs .reduce((result, [key, value]) => { // reduce pairs into an object result[key] = value; return result; },{}) ); const json = JSON.stringify(array, null, 2); console.log(json);

You can accomplish this string conversion through a series of regular expressions and a little decision logic to determine string and numeric values.

 var meh = "{orderid:996553,workorder:996553.010,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:996554,workorder:996554.010,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:999290,workorder:999290.010,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:999290,workorder:999290.020,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:999290,workorder:999290.030,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:999290,workorder:999290.040,shipped:000000001,received:000000001,status:GOOD},\\ {orderid:999290,workorder:999290.050,shipped:000000001,received:000000001,status:GOOD},"; meh = "[" + // enclose with [] meh.replace(/(\\w+)(?=:)/g, '"$1"') // search for words followed by a colon .replace(/,$/, '') // trim the ending comma .replace(/:([\\w.]+)/g, function(match, value){ // grab the values return ':' + ( // ensure preceding colon is in place isNaN(value) || value % 1 !== 0 ? // is it a non-float number? '"' + value + '"' : // enclose with "" if not a non-float number parseFloat(value) // parse if is number ); }) + "]"; // enclose with [] console.log(JSON.parse(meh));

How is the RPGLE program creating the string? If it is doing it piece by piece, then the RPGLE program could probably add the quotes and format the numbers correctly.
