使用POST请求发送嵌套JSON iOS Swift 3

let nestedJSON: [String: Any] = [
    "name": "John Doe",
    "age": 30,
    "address": [
        "street": "123 Main St",
        "city": "New York",
        "state": "NY"
    ]
]

do {
    let jsonData = try JSONSerialization.data(withJSONObject: nestedJSON, options: [])
    // jsonData可以用于发送请求
} catch {
    print("Error converting to JSON: \(error)")
}

let url = URL(string: "https://example.com/api/endpoint")!
var request = URLRequest(url: url)
request.httpMethod = "POST"

request.setValue("application/json", forHTTPHeaderField: "Content-Type")

request.httpBody = jsonData

let task = URLSession.shared.dataTask(with: request) { (data, response, error) in
    if let error = error {
        print("Error sending request: \(error)")
        return
    }
    
    if let data = data {
        // 处理响应数据
    }
}

task.resume()
