我需要使用
Image文件和
JSON调用Multipart请求.
我试过这个,但仍然得到错误.
// define parameters
let parameters = [
"hometown": "yalikavak","living": "istanbul"
]
Alamofire.upload(multipartFormData: { multipartFormData in
if let imageData = UIImageJPEGRepresentation(image,1) {
multipartFormData.append(imageData,withName: "file",fileName: "file.png",mimeType: "image/png")
}
for (key,value) in parameters {
multipartFormData.append((value?.data(using: .utf8))!,withName: key)
}},to: "upload_url",method: .post,headers: ["Authorization": "auth_token"],encodingCompletion: { encodingResult in
switch encodingResult {
case .success(let upload,_,_):
upload.response { [weak self] response in
guard let strongSelf = self else {
return
}
debugPrint(response)
}
case .failure(let encodingError):
print("error:\(encodingError)")
}
})
}
如何发送JSON？
在单个请求中尝试使用此代码进行多个上传图像,此代码已经可用.
// For Pass Valid Parameters & number of Images in Array in Image Upload Function
var dicImgData : NSMutableDictionary? = NSMutableDictionary()
if let img = UIImage(named: "Your Image") {
if let data:Data = UIImagePNGRepresentation(img) {
var imageData : NSData = data
dicImgData! .setObject(imageData,forKey: "data" as NSCopying)
dicImgData! .setObject("file",forKey: "name" as NSCopying)
dicImgData! .setObject("file.png",forKey: "fileName" as NSCopying)
dicImgData! .setObject("image/png",forKey: "type" as NSCopying)
let dicParameter = [
"hometown": "yalikavak","living": "istanbul"
]
self.uploadImage(url: "Your URL",Parameter: dicParameter,Images: [dicImgData])
}
}
func uploadImage (url: String,Parameter param : NSDictionary,Images arrImage: NSArray) -> Void
{
var requestURL : String! = url
let headers = [
"Authorization": "Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ==","Accept": "application/json",]
print("---------------------")
print("Request URL :- \(requestURL)")
print("---------------------")
Alamofire.upload(multipartFormData: { (data) in
for (key,value) in param {
data.append((value as! String).data(using: .utf8)!,withName: key as! String)
}
for imageInfo in arrImage
{
var dicInfo : NSDictionary! = imageInfo as! NSDictionary
data.append(dicInfo["data"] as! Data,withName: dicInfo["name"] as! String,fileName: dicInfo["fileName"] as! String,mimeType: dicInfo["type"] as! String)
dicInfo = nil
}
},to: requestURL,headers:nil,encodingCompletion: { (encodeResult) in
switch encodeResult {
case .success(let upload,_):
upload.responseJSON(completionHandler: { (response) in
switch response.result
{
case .success(let responseJSON):
guard let dicResponse = responseJSON as? NSDictionary else{
return
}
print("Response : \((dicResponse))")
case .failure(let error):
print(error)
break
}
})
case .failure(let error):
print(error)
break
}
})
}
