Decoding snake case

[Ivan C Myrvold]

I am posting a request:

struct UserCreateRequest: JsonRequest {
    typealias Result = User

    var firstName: String
    var lastName: String
    var email: String
    var password: String
    var role: String

    var routes: HttpRoute {
        ["users"]
    }
    var method: HttpMethod { .post }
    var body: HttpBody {
        HttpData.Json(UserCreateBody(firstName: firstName, lastName: lastName
        , email: email, password: password, role: role))
    }
    var usesSecureProtocol: Bool {
        false
    }
    var decodeSnakeCase: Bool {
        false
    }
}

The body of the request looks OK in the log, with camelcase:

[Squid] Scheduled request UserCreateRequest with identifier 5:

[Squid] }

But what is sent is snake case:

email: '[e-mail]',
password: 'duckduckgo',
last_name: 'Duck',
first_name: 'Donald',
role: '5c6be3ac710db32a9c77a12b'
}

[Oliver Borchert]

When you set the body to HttpData.Json, by default, a snake case encoder will be used as defined as follows:

fileprivate func snakeCaseJSONEncoder() -> JSONEncoder {
    let encoder = JSONEncoder()
    encoder.keyEncodingStrategy = .convertToSnakeCase
    return encoder
}

When you do not want that behavior, pass your own JSONEncoder instance like so:

HttpData.Json(
    UserCreateBody(firstName: firstName, lastName: lastName, email: email, password: password, role: role),
    encoder: JSONEncoder()
)

I'll close this for now as it is not an issue with the library itself.

Actually was an issue with the library itself, fixed the printing now ... thanks for the report :)
