来自SDK的意外响应

flutter swift ios

Shanu · 技术社区 · 2 年前

我在flutter应用程序中使用ios SDK扫描面部 methodChannel 我一直都会遇到这个错误。

flutter: Set Liveness Check status: SUCCESS
setLivenessChecks call args Optional({
    livenessCheck = 100;
})
creted liveness object LivenessCheck(rawValue: 100)
selectedProcess [<EFRSDK.LivenessCheckProcess: 0x303da9130>]
----------------------------------------------------onComplete
{"livenessActionResult":{"elapsedSec":"0","processStatus":"FAILED","livenessAction":""},"faceResult":{"feedbackMessage":"","faceImageHash":"","faceImage":"","processStatus":"FAILED","elapsesTimeSec":"0.0"},"lastWarningMessage":"Initialisation parametter missing"}
----------------------------------------------------
flutter: Set Liveness Check status: SUCCESS

下面是通过channel调用的方法的swift代码

if call.method == "setLivenessChecks"{
                    print("setLivenessChecks call args \(String(describing: call.arguments))")
                    if let args: [String:Any]  = call.arguments as? [String:Any]      {
                        if let check:String = args["livenessCheck"] as? String{
                            
                            if let checkCode:Int = Int(check){
                                let liveness:LivenessCheck = LivenessCheck(rawValue: checkCode) ?? .CLOSE_EYES_AND_OPEN
                                print("creted liveness object \(String(describing: liveness))")
                                let selectedProcess:[LivenessCheckProcess] = [LivenessCheckProcess(code: liveness, timeoutSec: 20, checkCycles: 1)]
                                print("selectedProcess \(String(describing: selectedProcess))")
                                do {
                                    try SDK.getInstance.liveness.setlivenessChecks(selectedProcess)
                                    result("SUCCESS")
                                }catch ValidationError.IllegalArgument {
                                        // Show alert: ""
                                    result(FlutterError(code: "1", message: "setlivenessChecksfailed", details: ""))
                                    
                                } catch {
                                    result(FlutterError(code: "1", message: "setlivenessChecksfailed", details: ""))
                                }
                            }
                        }
                    }
                }

我对swift btw不太熟悉。

运行flutter应用程序时,vscode控制台中没有显示异常或错误。这些是我从Xcode中得到的错误
