I am trying to get data in correct form, and here is my request example:
var request = URLRequest(url: url)
request.httpMethod = "GET"
request.allHTTPHeaderFields = [
"Content-Type": "http",
"Authorization": token
]
let session = URLSession.shared
session.dataTask(with: request) { data, response, error in
guard let data = data else {
completion(.failure(.invalidData))
return
}
do {
if let string = String(data: data, encoding: .utf8) { print(string) }
let json = try JSONSerialization.jsonObject(with: data, options: [])
print(json)
completion(.failure(.invalidURL))
}
catch {
completion(.failure(.decodingProblem))
}
}.resume()
After that request I always get the JSON result like the next one. But I would like to get correct text without unicode sequence

}
}
So I would like to get correct text without unicode sequence.
CodePudding user response:
Your JSON string has some issues. When using \U it should send 4 bytes (8 hexa characters) but it is sending only 2 bytes (4 hexa characters). If you have control of what is being returned the easiest solution is to return \u instead of \U which is the correct unicode escape for 2 bytes otherwise you will have to do some string manipulation and apply a string transform before decoding your json:
let jsonData = Data(#"{"x_city":"\U041a\U0438\U0457\U0432"}"#.utf8)
let jsonString = String(data: jsonData, encoding: .utf8) ?? ""
let cleanedData = Data(
jsonString
.replacingOccurrences(of: #"\U"#, with: #"\u"#)
.applyingTransform(.init("Hex-Any"), reverse: false)!
.utf8
)
struct Response: Codable {
let xCity: String
}
do {
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
let response = try decoder.decode(Response.self, from: cleanedData)
print(response) // Response(xCity: "Київ")
} catch {
print(error)
}
