I have defined a class Email having following details:
Email
:
String name;
String subject;
List<String> attachment;
String jsonContent;
....
In above class, jsonContent
variable is loaded with a strinigified json object.
Once an Email object is created, I am stringifying the whole Email object and sending to client.
I need to parse Email object in client and render it in UI.
But it throws parsing error for Email object in client, ie
JSON.parse(emailString);
because jsonContent
field is having double quotes within it.
It is a problem of stringifying a JAVA object having a jsonContent
variable which is already stringified.
One way to fix it is define jsonContent
variable as a object rather than as a String. Is there any other fix for it?
Example Email JSON:
{
"id": "e4682ec0-a7c3-4f4d-abcd-f404f5fdb1eb",
"entityType": "email",
"subject": "Presentation 1",
"from": "aaa <a@a.com>",
"to": [
"undisclosed-recipients:;"
],
"cc": [],
"bcc": [
"jack.porter@forwardaccelerator.com"
],
"recievedDate": 1423101398000,
"recievedDateString": "Wed, 4 Feb 2015 12:26:38 -0800",
"bodyText": " Please find the link to my recent presentation",
"jsonContent": "{
"typeOfMail": "NormalMail",
"normalMail": {
"mailType": "NormalMail",
"paragraphs": [
"Pleasefindthelinktomyrecentpresentation"
]
}
}"
}
You will need to escape a lot of strings to get stuff as strings.
to store a json object in a json object you need to escape it. so
"jsonContent": "{
"typeOfMail": "NormalMail",
"normalMail": {
"mailType": "NormalMail",
"paragraphs": [
"Pleasefindthelinktomyrecentpresentation"
]
}
}"
becomes
"jsonContent": "{\\"typeOfMail\\": \\"NormalMail\\",\\"normalMail\\":{\\"mailType\\":\\"NormalMail\\",\\"paragraphs\\":[\\"Pleasefindthelinktomyrecentpresentation\\"]}}"
Now if you want to compile it in java, this is how it should look like if you would type it manually as an Java string(execute snippet)
var json = { "id": "e4682ec0-a7c3-4f4d-abcd-f404f5fdb1eb", "entityType": "email", "subject": "Presentation 1", "from": "aaa <a@a.com>", "to": [ "undisclosed-recipients:;" ], "cc": [], "bcc": [ "jack.porter@forwardaccelerator.com" ], "recievedDate": 1423101398000, "recievedDateString": "Wed, 4 Feb 2015 12:26:38 -0800", "bodyText": " Please find the link to my recent presentation", "jsonContent": "{\\"typeOfMail\\": \\"NormalMail\\",\\"normalMail\\":{\\"mailType\\":\\"NormalMail\\",\\"paragraphs\\":[\\"Pleasefindthelinktomyrecentpresentation\\"]}}" } console.log("This is the json object having a string with json"); console.log(json); console.log("This is it parsed as string"); var x = {hello:JSON.stringify(json)}; console.log(JSON.stringify(x).substring(10,JSON.stringify(x).length-2)); document.getElementById('content').textContent = JSON.stringify(x).substring(10,JSON.stringify(x).length-2);
<div id="content"></div>
And this is how it would look like in a JSON file/request answer thats sent
{
"id": "e4682ec0-a7c3-4f4d-abcd-f404f5fdb1eb",
"entityType": "email",
"subject": "Presentation 1",
"from": "aaa <a@a.com>",
"to": [
"undisclosed-recipients:;"
],
"cc": [],
"bcc": [
"jack.porter@forwardaccelerator.com"
],
"recievedDate": 1423101398000,
"recievedDateString": "Wed, 4 Feb 2015 12:26:38 -0800",
"bodyText": " Please find the link to my recent presentation",
"jsonContent": "{\"typeOfMail\": \"NormalMail\",\"normalMail\":{\"mailType\":\"NormalMail\",\"paragraphs\":[\"Pleasefindthelinktomyrecentpresentation\"]}}"
}
Now I don't see why you want jsonContent as a string, as you could just pass it as an object(remove the quotes surrounding it so you get
"jsonContent": {
"typeOfMail": "NormalMail",
"normalMail": {
"mailType": "NormalMail",
"paragraphs": [
"Pleasefindthelinktomyrecentpresentation"
]
}
}
and if you need it as string in javascript you can just do JSON.stringify(json.jsonContent);
to get the same result easier.
