json - SwiftHttp + JSON解码器

Question

我尝试解析来自这样的服务器的 json 响应

HTTP.GET(ServerPatientApi.SPLASH, parameters: nil) { response in
            if let error = response.error {
                listener.onException(error)
                return;
            }

            DispatchQueue.main.async (execute: {
                let res = try decoder.decode(PatientSplashModel.self, from: response.data)
                listener.onSplashLoaded()
            })
        }

但我收到以下错误:

Invalid conversion from throwing function of type '() throws -> ()' to non-throwing function type '@convention(block)

在区 block :

DispatchQueue.main.async (execute: {
                let res = try decoder.decode(PatientSplashModel.self, from: response.data)
                listener.onSplashLoaded()
            })

我认为错误是由以下原因引起的:

PatientSplashModel.self

如何解决这个问题？

谢谢

该错误有点误导，您必须将 try 语句包装在 do catch block 中

DispatchQueue.main.async {
    do {
        let res = try decoder.decode(PatientSplashModel.self, from: response.data)
        listener.onSplashLoaded()
    } catch { print(error) }
 }
