GET-URL编码

模型

struct Query: Encodable {
    let year: Int
    let month: Int
    let day: Int
}

let query = Query(year: 2021, month: 7, day: 29)
// 默认encoder: URLEncodedFormParameterEncoder.default
AF.request("https://httpbin.org/get", parameters: query).response { response in
    debugPrint(response)
}

字典

let query = [
    "year": 2021,
    "month": 7,
    "day": 29
]

AF.request("https://httpbin.org/get", parameters: query).response { response in
    debugPrint(response)
}

POST-JSON编码

模型

struct User: Encodable {
    let name: String
    let password: String
}

let user = User(name: "hello", password: "world")

AF.request("https://httpbin.org/post", method: .post, parameters: user, encoder: JSONParameterEncoder.default).response { response in
    debugPrint(response)
}

字典

let user = [
    "name": "hello",
    "password": "world"
]

AF.request("https://httpbin.org/post", method: .post, parameters: user, encoder: JSONParameterEncoder.default).response { response in
    debugPrint(response)
}

响应

JSON

AF.request("https://httpbin.org/json").responseJSON { response in
    debugPrint(response)
}

Data

AF.request("https://httpbin.org/json").responseData { response in
    debugPrint(response)
}

String

AF.request("https://httpbin.org/json").responseString { response in
    debugPrint(response)
}

模型解析

struct HTTPBinResponse: Decodable {
    let args: [String: String]
    let headers: [String: String]
    let origin: String
    let url: String
}

AF.request("https://httpbin.org/get").responseDecodable(of: HTTPBinResponse.self) { response in
    debugPrint(response)
}
