Alamofire – 使用照片时图像上传失败
亲爱的stackoverflow社区，
我正在使用Alamofire将JSON和图像发送到REST API的iOS应用程序中工作。 图像被图像select器检索并存储在一个数组中。 问题是，只要我使用从互联网上下载的图像等图像上传工作。一旦我尝试上传照片，这是我正在使用的手机（从照片库中select）拍摄的上传失败并抛出一个400 – 错误的请求错误。 奇怪的是，当我可以上传照片，这是从另一个iPhone采取的，但被发送给我，但照片，这是用手机本身没有工作…是否有人有一个想法，为什么这个问题发生？ 我有一个怀疑，iPhone的照片格式或数据可能不同于下载的，由于HDR和其他的东西，但我不知道这是否是问题。
下面是我使用的代码，它的标准很漂亮：
func POST_WITH_ATACHMENTS(description: String, attachments: [UIImage], returnCompletion: @escaping (Bool) -> ()) { let parameters = ["ticket":"{ \"description\" : \"" + description + "\"}"] APIManager.Manager.upload(multipartFormData: { multipartFormData in for (key, value) in parameters { multipartFormData.append((value.data(using: .utf8)!), withName: key, mimeType: "application/json") } var counter = 1 for image in attachments { multipartFormData.append(UIImagePNGRepresentation(image)!, withName: "attachments", fileName: "attachment" + String(counter) + ".png", mimeType: "image/png") counter += 1 } }, to: restURL!, method: .post, headers:["Authorization" : loginString], encodingCompletion: { encodingResult in switch encodingResult { case .success(let upload, _, _): upload.responseJSON { response in debugPrint(response) if (upload.response?.statusCode == 201) { returnCompletion(true) } else { returnCompletion(false) } } case .failure(let encodingError): print(encodingError) returnCompletion(false) } }) } 这里是使用AlamoFire上传图片的web服务
