आईओएस स्विफ्ट में JSON से स्ट्रिंग को कैसे परिवर्तित करें?

Question

यहाँ नीचे Json उत्पादन के लिए कोड है:

let params : [[String : AnyObject]] = [["name" : "action", "value" : "pay" ],["name" : "cartJsonData" , "value" : ["total": 1,"rows":[["quantity": “1” ,"title":"Donation for SMSF India - General Fund","price":"1","itemId":"DN001","cost": “1”,”currency":"INR"]]]], ["name" : "center", "value" : "Chennai"], ["name" : "flatNumber", "value" : "503"], ["name" : "panNumber", "value" : ""], ["name" : "payWith"], ["name" : "reminderFrequency","value" : "Monthly"], ["name" : "shipToAddr1"], ["name" : "shipToAddr2"], ["name" : "shipToCity"], ["name" : "shipToCountryName" , "value" : "India"], ["name" : "shipToEmail", "value" : “01034_186893@gmail.com"], ["name" : "shipToFirstName" , "value": "4480101010"], ["name" : "shipToLastName"], ["name" : "shipToPhone", "value" : "4480101010"], ["name" : "shipToState"], ["name" : "shipToZip"], ["name" : "userId", "value" : “null”], ["name" : "shipToCountry", "value" : "IN"]] 

var jsonObject: NSData? = nil 

do { 
    jsonObject = try NSJSONSerialization.dataWithJSONObject(params, options: NSJSONWritingOptions()) 
    print(jsonObject) // This will print the below json. 
} 
catch{} 

मुद्रण JSONObject, मैं इस एक मिल गया।

[{ "मूल्य": "भुगतान", "नाम": "कार्रवाई"}, { "मूल्य": { "पंक्तियों": [{ "कीमत": "1", "मात्रा": "1", "लागत": "1", "मुद्रा": "आईएनआर", "आइटम आईडी": "डीएन 001", "शीर्षक": "एसएमएसएफ इंडिया - जनरल फंड के लिए दान" }], "कुल": 1}, "नाम": "कार्टजसनडाटा"}, {"मूल्य": "चेन्नई", "नाम": "केंद्र"}, {"मूल्य": "503", "नाम": "flatNumber"}, { "मूल्य": "", "नाम": "panNumber"}, {"name": "payWith"}, {"value": "मासिक", "नाम": "अनुस्मारक फ़्रिक्वेंसी"}, {"नाम" : "shipToAddr1"}, { "name": "shipToAddr2"}, {"name": "shipToCity"}, {"value": "India", "name": "shipToCountryName" }, {"value": "01034_186893@gmail.com", "name": "shipToEmail"}, {"value": "4480101010", "name": "shipToFirstName"}, {"name": " shipToLastName "}, {" value ": " 4480101010 "," name ":" shipToPhone "}, {" name ":" shipToState "}, { " नाम ":" shipToZip "}, {" value ":" अशक्त "," नाम ":" userId "}, { " मूल्य ":" में "," नाम ":" shipToCountry "}]

और मैं JSON नीचे प्रारूप में होना चाहता हूँ।

[{ "नाम": "कार्रवाई", "मूल्य": "भुगतान"}, { "नाम": "cartJsonData", "मूल्य": "{\" कुल \ ": 1, \ "पंक्तियां \": [{\ "itemId \": \ "DN002 \", \ "शीर्षक \": \ " के लिए दान एसएमएसएफ भारत - सामान्य फंड \", \ "मात्रा \": \ "100 \ ", \" मुद्रा \ ": \" INR \ ", \" मूल्य \ ": \" 1 \ ", \" लागत \ ": \" 100 \ "}]}" }, {"name": " केंद्र "," मूल्य ":" चेन्नई "}, {" नाम ":" फ्लैट नम्बर ", " मूल्य ":" "}, {" नाम ":" पैन नम्बर "," मान ":" एएसएसडीडीबीबीडीजेडी "}, { "नाम": "payWith"}, {"name": "अनुस्मारक फ़्रिक्वेंसी", "वैल ue ":" मासिक " }, {" नाम ":" shipToAddr1 "}, {" name ":" shipToAddr2 "}, {" name ": " shipToCity "}, {" name ":" shipToCountryName "," मूल्य ":" भारत "}, { " नाम ":" shipToEmail "," मूल्य ":" सुधाकर@gmail.com "}, {" नाम ": " शिप टॉफ़र्ननाम "," मूल्य ":" राजू "}, {"Name": "shipToLastName"}, { "name": "shipToPhone", "value": "1234567890"}, {"name": "shipToState"}, {"name": "shipToZip"}, { "नाम": "userId", "मूल्य": "अशक्त"}, { "नाम": "shipToCountry", "मूल्य": "में"}]

यह कैसे किया जा सकता है? केवल cartJsonData में मान बदलने की जरूरत है। क्या कोई इसे हल करने में मेरी मदद कर सकता है?

Answer 1

इसे आजमाएं।

func jsonToString(json: AnyObject){ 
     do { 
      let data1 = try NSJSONSerialization.dataWithJSONObject(json, options: NSJSONWritingOptions.PrettyPrinted) // first of all convert json to the data 
      let convertedString = String(data: data1, encoding: NSUTF8StringEncoding) // the data will be converted to the string 
      print(convertedString) // <-- here is ur string 

     } catch let myJSONError { 
      print(myJSONError) 
     } 

    } 

Answer 2

स्विफ्ट 3,1

func jsonToString(json: AnyObject){ 
    do { 
     let data1 = try JSONSerialization.data(withJSONObject: json, options: JSONSerialization.WritingOptions.prettyPrinted) // first of all convert json to the data 
     let convertedString = String(data: data1, encoding: String.Encoding.utf8) // the data will be converted to the string 
     print(convertedString ?? "defaultvalue") 
    } catch let myJSONError { 
     print(myJSONError) 
    } 

} 

Answer 3

स्विफ्ट 4।0

static func stringify(json: Any, prettyPrinted: Bool = false) -> String { 
    var options: JSONSerialization.WritingOptions = [] 
    if prettyPrinted { 
     options = JSONSerialization.WritingOptions.prettyPrinted 
    } 

    do { 
     let data = try JSONSerialization.data(withJSONObject: json, options: options) 
     if let string = String(data: data, encoding: String.Encoding.utf8) { 
     return string 
     } 
    } catch { 
     print(error) 
    } 

    return "" 
} 

प्रयोग

stringify(json: ["message": "Hello."])
