Question

我已经实现了更改个人资料图片的功能。实施流程如下

选择图像->上载到服务器->从服务器下载并显示它的用户。

此流程随机运行正常。图片上传总是成功的，而我总是会得到一个URL作为响应。但是，当我尝试显示该图像时，以某种方式无法在图像视图中显示该图像。但相同的URL在所有浏览器（Sfari，chrome，IE）中显示图像。我无法理解上载或下载图像时遇到的问题。

代码附在下面。任何帮助，将不胜感激。

图片上传：-

func updateProfile(userUpdateRequest:UsersRequest ,completionBlock completion: @escaping ( _ fileURL : String)->Void, failureBlock failure: @escaping ( _ error: String) -> Void)  {

        let url = "\(SPConfigurations.getBaseURL())/\(APIConstants.getProfileUpdateRequestRoute(userRequest: userUpdateRequest))"

        Alamofire.upload(multipartFormData: { multipartFormData in
            if (userUpdateRequest.image != nil) {
                let  fileData = userUpdateRequest.image!.jpegData(compressionQuality: 0.5)!
                 multipartFormData.append(fileData, withName: "file", fileName:UUID().uuidString , mimeType: "image/jpeg")
            }
        }, to: url, method: .post, headers:APIConstants.authHeaders()) { encodingResult in
            switch encodingResult {
            case .success(let upload, _, _):
                upload.responseJSON { response in

                    if let err = response.error {
                        failure(err.localizedDescription)
                        return
                    } else {
                        if let result = response.result.value as? [String:Any] {
                            if let dataValue = result["data"] as? [String:Any] {
                                if let fileUrl = dataValue["profile_picture_url"] as? String {
                                    completion(fileUrl)
                                } else {
                                    completion("")
                                }
                            }
                        }
                    }
                }
            case .failure(let encodingError):
                failure(encodingError.localizedDescription)
            }
        }
    }

图片下载：-Imageview的扩展及其工作正常除了我要上传的图像以外的所有图像。

func setImage (urlString: String,placeHolderString : String = "placeholder") {

        let placeHolderImage = UIImage.init(named: placeHolderString)

        if(urlString.trim() == "") {
            self.image = placeHolderImage
            return
        }

        self.kf.setImage(with: URL(string: urlString)!, placeholder: placeHolderImage, options: nil, progressBlock: { (receivedSize, totalSize) -> () in

        }, completionHandler: { (image, error, cacheType, imageURL) -> () in
            DispatchQueue.main.async {
                if(image != nil) {
                    self.image = image
                }
            }
        }
        )
    }

Answer 1

尝试设置没有进度条的图像

self.imageView?.kf.setImage(with: URL(string: urlString)!)

图像视图中显示了一些随机图像，而不是URL中的实际图像：iOS，Swift
