I am tring to decode json with URL value which contains double quotes but I am always getting "The given data was not valid JSON." or "Invalid URL String." error while decoding the object.
let data = Data("""{ "contentUrl":"https://somedomain.come/folder/1-test_Romio's-\"Video-?hl=en-GB" }
""".utf8)
do {
let decoder = JSONDecoder()
let object = try decoder.decode(Model.self, from: data)
print(object)
} catch {
print(error)
}
struct Model: Codable {
let contentUrl: URL
}
How can I escape this double quotes in the url, given that the url is generated based on user input so the user can enter " double quotes ?
The JSON spec asks that double quotes in strings be preceded by a backslash.
In Swift this string
"aString \" With a Double Quote"
has a double quote with no backslash in front of it.
To get a string that has a backslash and a quote it would have to be:
"aString \\\" With a Double Quote"
You should change your sample to:
"{ "contentUrl":"https://somedomain.come/folder/1-test_Romio's-\\\"Video-?hl=en-GB" }"
That will make it valid JSON, though it still won't be valid URL. To be a valid URL you have to escape the double quotes using percent escape encoding
