get json from file code example
Example 1: get json from file python
import json
with open('data.txt') as json_file:
data = json.load(json_file)
for p in data['people']:
print('Name: ' + p['name'])
print('Website: ' + p['website'])
print('From: ' + p['from'])
print('')
Example 2: parse local json file
// pure javascript
let object;
let httpRequest = new XMLHttpRequest(); // asynchronous request
httpRequest.open("GET", "local/path/file.json", true);
httpRequest.send();
httpRequest.addEventListener("readystatechange", function() {
if (this.readyState === this.DONE) {
// when the request has completed
object = JSON.parse(this.response);
}
});
Example 3: read json data from file
// consider your file data is something like json string but aving parse issue
//that means some additional char is there
fs.readFile(ROLES_FILE, "utf8", (err, data) => {
if (err) {
res.status(403).json({});
}
const [localScope, action] = scope.split(".");
const mapper = JSON.parse(data.toString("utf8").replace(/^\uFEFF/, ""));
const isAllowed = checkRole(mapper, localScope, action, role);
if (isAllowed) {
next();
} else {
res.status(403).json({});
}
