How can I set JsonSerializer to not add "\u0022" to string for EventData property? Because I get:
{"Id":5,"CreateDate":"2021-04-21T05:26:30.9817284Z","EventData":"{\u0022Id\u0022:1,\u0022Email\u0022:\u0022test@test.test\u0022}"}
I will never deserialize EventData, it must be readable. And I want:
{"Id":5,"CreateDate":"2021-04-21T05:26:30.9817284Z","EventData":"{Id:1,Email:test@test.test}"}
My code:
public class EmailSent
{
public int Id { get; set; }
public string Email { get; set; }
}
public class UserCreated
{
public int Id { get; set; }
public DateTime CreateDate { get; set; }
public string EventData { get; set; }
}
var emailSent = new EmailSent
{
Id = 1,
Email = "test@test.test"
};
var userCreated = new UserCreated
{
Id = 5,
CreateDate = DateTime.UtcNow,
EventData = JsonSerializer.Serialize(emailSent) // I will never deserialize it
};
string result = JsonSerializer.Serialize(userCreated);
You can use, for example, UnsafeRelaxedJsonEscaping:
var serializeOptions = new JsonSerializerOptions
{
WriteIndented = true,
Encoder = System.Text.Encodings.Web.JavaScriptEncoder.UnsafeRelaxedJsonEscaping
};
string json = JsonSerializer.Serialize(userCreated, serializeOptions);
This will produce the following output:
{
"Id": 5,
"CreateDate": "2021-04-21T07:49:23.4378969Z",
"EventData": "{\"Id\":1,\"Email\":\"test@test.test\"}"
}
Reference: How to customize character encoding with System.Text.Json. Please read the caution there:
Caution
Compared to the default encoder, the UnsafeRelaxedJsonEscaping encoder is more permissive about allowing characters to pass through unescaped: (...)
You can specify 'JSONSerializerOptions' Encoder equal to JavaScriptTenCoder. Create(new TextEncoderSettings(UnicodeRanges.All)) like imageenter image description here
