SwiftModel

Data <-> String <-> Any(Swift中的json结构, 本工具中以JSON结构体代替) <-> Model(Codable) 此四种类型数据任何方式转化

1.Bool解码处理

do {
    let data: Data = """

    } catch {
        XCTFail("error")
    }
}

13.Double解码处理(同上)

14.String解码处理

do {
    let data: Data = """
        [true, false, 0, 1, 2, 3, 4.5, -6.7, null, [], [null], [true], [false], [0], [1], [2], [3], [4.5], [6.7], {}, {"a": "b"}]
    """.data(using: String.Encoding.utf8) ?? Data()

        let model: [String] = try decoder.decode(type: [String].self, from: data) 
        XCTAssertEqual(model[0], "true")
        XCTAssertEqual(model[1], "false")

        XCTAssertEqual(model[15], "[]")
        XCTAssertEqual(model[16], "[]")
        XCTAssertEqual(model[17], "[]")
        XCTAssertEqual(model[18], "[]")
        XCTAssertEqual(model[19], "[:]")
        XCTAssertEqual(model[20], "[:]")
    } catch {
        XCTFail("error")
    }
}

15.自定义模型与JSONKey对应(常规Codable提供的CodingKey自定义,当只能一对一的转化,本工具可以实现一对多映射,因为鬼知道服务端下发的数据字段啥时候改,或者为了兼容多个字段都他妈下发过来,或者一会下发这个一会下发那个.本工具均可以处理)

do {
    struct Root: Codable, MappingDecodingKeys {
        static func modelDecodingKeys() -> [String: [String]] {
            return ["info": ["a", "b"], "b": ["b"]]
        }
        /// 模型的info字段接受json字段("a", "b")
        let info: Bool
        let b: String
    }
    let data: Data = """
        {"a": true, "b": ""}
    """.data(using: String.Encoding.utf8) ?? Data()
    let decoder = PowerJSONDecoder()
    do {
        let model = try decoder.decode(type: Root.self, from: data)
        XCTAssertEqual(model.info, true)
    } catch {
        XCTAssertNil(error, error.localizedDescription)
    }
}

还有写特性可见具体的Test,

感谢 JSON 解析功能是照搬的 并不是用Codable内部的功能(因为Codable提供的关于解析过程的比较少),壳子模仿Codable的API,使用方便,欢迎大家提PR!!!共同学习,由于底层不是Codable解析目前支持Bool, Int, Int8, Int16, Int32, Int64, UInt, UInt8, UInt16, UInt32, UInt64, Float, Double, String, URL, Date, Data
