swift - 获取分段上传 Alamofire5 的上传进度

Question

在 Alamofire5 之前，我们可以使用 uploadRequest 的 encodingReresult 得到 uploadProgress .
但是现在在将 Alamofire 上传到版本 5 之后，基于 Alamofire Documentation ，我们可以使用 .uploadProgress为了获得上传进度处理程序。

这是我的代码:

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)
        }

但是 uploadProgress在上传过程中从未调用关闭。

我查了很多 stackoverflow问题，但没有人工作。

更换你的

.uploadProgress { progress in 
            print(progress)
        }

和

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

它会给你输出:

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

编辑 :

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)")
         }
