如何打印Restkit(IOS)发送的正文

import RestKit

func sendRequest() {
    let request = RestRequest(method: .post, path: "/path/to/api")
    request.addHeader("Content-Type", value: "application/json")
    request.addHeader("Authorization", value: "Bearer YOUR_ACCESS_TOKEN")

    let parameters: [String: Any] = [
        "key1": "value1",
        "key2": "value2"
    ]

    request.messageBody = try? JSONSerialization.data(withJSONObject: parameters, options: [])

    request.responseObject { (response: RestResponse<Any>) in
        switch response.result {
        case .success(let value):
            print("Response: \(value)")
        case .failure(let error):
            print("Error: \(error)")
        }
    }
}

sendRequest()

print("Request body: \(String(data: request.messageBody!, encoding: .utf8)!)")
