获取分段上传 Alamofire5 的上传进度

Question

Before Alamofire5 we could user encodingReesult of uploadRequest to get uploadProgress . But now after uploading Alamofire to version 5, based on Alamofire Documentation , we can use .uploadProgress in order to get upload progress handler.

Here's my code:

AF.upload(multipartFormData: { multipartFormData in
            multipartFormData.append(fileContent, withName: "file", fileName: filePath.lastPathComponent)
            multipartFormData.append(token.data(using: .utf8)!, withName: "token")
        }, to: uploadURL)
        .uploadProgress { progress in 
            print(progress)
        }
        .responseJSON { [weak self] response in
            print(response)
        }

But uploadProgress closure never called during upload progress.

I've checked many stackoverflow questions but no one worked.

Answer 1

replace your

.uploadProgress { progress in 
            print(progress)
        }

with

.uploadProgress(closure: { (progress) in
print("Upload Progress: \(progress.fractionCompleted)")
})

it will give you output as:

Upload Progress: 0.035203331252732804
Upload Progress: 0.035203331252732804
Upload Progress: 0.0528049968790992
Upload Progress: 0.088008328131832
Upload Progress: 0.1584149906372976
Upload Progress: 0.2112199875163968
Upload Progress: 0.2288216531427632
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962
Upload Progress: 0.24642331876912962

Edit:

AF.upload(multipartFormData: { MultipartFormData in
        MultipartFormData.append(fileContent, withName: "file" , fileName: filePath.lastPathComponent , mimeType: "image/jpeg")
        for(key,value) in dictonary {
            MultipartFormData.append(token.data(using: String.Encoding.utf8)!, withName: "token")
        }
    }, to: uploadURL, method: .post, headers: ["Content-Type": "application/json")

        .uploadProgress(closure: { (progress) in
            print("Upload Progress: \(progress.fractionCompleted)")
        })

        .responseJSON{ (response) in
            debugPrint("SUCCESS RESPONSE: \(response)")
         }

If u happen to have installed a library for network traffic debugging like Wormholy , then, checkout this issue thread . In short note, it's the issue with the library & uninstalling it, solves the problem. Not sure with other network debuggers though. To make things clear, try to playaround in a new, clean project and see if alamofire works in such environment.

I also have this issue. I try to solve it by many methods. In the end, I uninstall the pod "CocoaDebug". It worked. So I think maybe is CocoaDebug disturbing the network.
