As I mentioned in THIS QUESTION, I have problem when getting the response from the server.
I receive an array of objects with these attributes:
[{
\"
you can use replacer in JSON.stringify() like :
var obj = {
"Id": 143187001116603, // VERY big number which I want to convert it to string
"Name": "تملی612", // string
"Title": "تسهیلات مسکن بانک ملی-اسفند96", // string
"InsCode": "IRO6MELZ96C1" // string
};
function replacer(name, val) {
// convert Number to string
if ( val && val.constructor === Number ) {
return val.toString();
} else {
return val; // return as is
}
};
JSON.stringify(obj, replacer, 4);
// result
{
"Id": "143187001116603",
"Name": "تملی612",
"Title": "تسهیلات مسکن بانک ملی-اسفند96",
"InsCode": "IRO6MELZ96C1"
}
function replacer(key, value) {
// Filtering out properties
if (key === 'Id') {
return value.toString();
}
return value;
}
const t = [{
"Id": 143187001116603, // VERY big number which I want to convert it to string
"Name": "تملی612", // string
"Title": "تسهیلات مسکن بانک ملی-اسفند96", // string
"InsCode": "IRO6MELZ96C1" // string
},
{
"Id": 9481703061634967, // VERY big number which I want to convert it to string
"Name": "تملی232", // string
"Title": "تسهیلات مسکن بانک ملی-اسفن216", // string
"InsCode": "IRO6MSDZ96C1" // string
}
]
const stringifiedValue = JSON.stringify(t, replacer)
console.log(JSON.parse(stringifiedValue))
Try this using replacer callback for JSON.stringify.
Feedbacks welcome.
Assuming that you receive the data as a Json string with the numbers inside them, there is no way to preserve the data using JSON.parse. Even if you use the second argument to add a transformation function, it will only be run after the default parsing has parsed the numbers with a loss of information in case of large numbers. You need to manipulate the string directly to wrap the number in quotes using e.g. a regular expression.
You can also use the json-bigint npm package: https://www.npmjs.com/package/json-bigint
Transform the response to string
, then apply a repalce with a regex to convert Id
field to string type:
const axios = require('axios');
axios.get(url, { transformResponse: [data => data] }).then(response => {
let parsed = JSON.parse(response.data.replace(/"Id":(\d+),/g, '"Id":"$1",'));
console.log(parsed);
});
