我正在使用 multipart 上传图片。此代码在 swift 4 和 Alamofire 4 中运行良好。请为此提供任何解决方案。
public class func callsendImageAPI(param:[String: Any],arrImage:[UIImage],imageKey:String,URlName:String,controller:UIViewController, withblock:@escaping (_ response: AnyObject?)->Void){
Alamofire.upload(multipartFormData:{ MultipartFormData in
for (key, value) in param {
MultipartFormData.append((value as AnyObject).data(using: String.Encoding.utf8.rawValue)!, withName: key)
}
for img in arrImage {
guard let imgData = img.jpegData(compressionQuality: 1) else { return }
MultipartFormData.append(imgData, withName: imageKey, fileName: FuncationManager.getCurrentTimeStamp() + ".jpeg", mimeType: "image/jpeg")
}
},usingThreshold:UInt64.init(),
to: "URL",
method:.post,
headers:["Content-type": "multipart/form-data",
"Content-Disposition" : "form-data"],
encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload, , ):
upload.uploadProgress(closure: { (Progress) in
print("Upload Progress: \(Progress.fractionCompleted)")
})
upload.responseJSON { response in
switch(response.result) {
case .success(_):
let dic = response.result.value as! NSDictionary
if (dic.object(forKey: "status")! as! Int == 1){
withblock(dic.object(forKey: "data") as AnyObject)
}else if (dic.object(forKey: Message.Status)! as! Int == 2){
print("error message")
}else{
print("error message")
}
case .failure(_):
print("error message")
}
}
case .failure(let encodingError):
print("error message")
}
})}
提前致谢。
最佳答案
Almofire 5.0 和 Swift 5.0
//Set Your URL
let api_url = "YOUR URL"
guard let url = URL(string: api_url) else {
return
}
var urlRequest = URLRequest(url: url, cachePolicy: .reloadIgnoringLocalAndRemoteCacheData, timeoutInterval: 10.0 * 1000)
urlRequest.httpMethod = "POST"
urlRequest.addValue("application/json", forHTTPHeaderField: "Accept")
//Set Your Parameter
let parameterDict = NSMutableDictionary()
parameterDict.setValue(self.name, forKey: "name")
//Set Image Data
let imgData = self.img_photo.image!.jpegData(compressionQuality: 0.5)!
// Now Execute
AF.upload(multipartFormData: { multiPart in
for (key, value) in parameterDict {
if let temp = value as? String {
multiPart.append(temp.data(using: .utf8)!, withName: key as! String)
}
if let temp = value as? Int {
multiPart.append("\(temp)".data(using: .utf8)!, withName: key as! String)
}
if let temp = value as? NSArray {
temp.forEach({ element in
let keyObj = key as! String + "[]"
if let string = element as? String {
multiPart.append(string.data(using: .utf8)!, withName: keyObj)
} else
if let num = element as? Int {
let value = "\(num)"
multiPart.append(value.data(using: .utf8)!, withName: keyObj)
}
})
}
}
multiPart.append(imgData, withName: "file", fileName: "file.png", mimeType: "image/png")
}, with: urlRequest)
.uploadProgress(queue: .main, closure: { progress in
//Current upload progress of file
print("Upload Progress: \(progress.fractionCompleted)")
})
.responseJSON(completionHandler: { data in
switch data.result {
case .success(_):
do {
let dictionary = try JSONSerialization.jsonObject(with: data.data!, options: .fragmentsAllowed) as! NSDictionary
print("Success!")
print(dictionary)
}
catch {
// catch error.
print("catch error")
}
break
case .failure(_):
print("failure")
break
}
})
很高兴为您提供帮助:)
