我正在使用Alamofire尝试使用image shack API在图像小屋服务器上放置图像。我没有得到回复并得到错误:
FAILURE:Error Domain = NSCocoaErrorDomain Code = 3840“无效的值 在角色0周围。
我也强调了错误在代码中的引用位置:
let imageName = "pano.jpg"
let postImage = UIImage(named: imageName)
let urlStr = "https://post.imageshack.us/upload_api.php"
let theUrl:NSString = urlStr.stringByRemovingPercentEncoding!
let url = NSURL(string: theUrl as String)!
let imgData = UIImageJPEGRepresentation(postImage!, 0.2)!
let keyData = "0345CHKMad115dd32980b363be5f2d34731b8110".dataUsingEncoding(NSUTF8StringEncoding)!
let keyJSON = "json".dataUsingEncoding(NSUTF8StringEncoding)!
Alamofire.upload(.POST, url, multipartFormData: { MultipartFormData in
MultipartFormData.appendBodyPart(data: imgData, name: "fileupload", mimeType: "image/jpg")
MultipartFormData.appendBodyPart(data: keyData, name: "key")
MultipartFormData.appendBodyPart(data: keyJSON, name: "format")
}) {encodingResult in
switch encodingResult {
case .Success(let upload, _, _):
upload.responseJSON(completionHandler: { response in
print(response) //ERROR HERE
guard let data = response.result.value
else{
print("Request failed with error data)")
return
}
if let info = data as? Dictionary<String, AnyObject> {
if let links = info["links"] as? Dictionary<String, AnyObject> {
if let imgLink = links["image_link"] as? String {
print(imgLink)
}
}
}
})
我完全迷失了这个问题意味着任何帮助都会很棒。

在将url
传递给函数do:
//Convert the NSURL to a NSString
let urlString:NSString = url.absoluteString() as! NSString
//Remove Percent Encoding
let theUrl:NSString = urlString.stringByRemovingPercentEncoding()
//Place Back into NSURL
let newUrl = NSURL(string:theUrl)
并通过newUrl
代替url
。最好在实例化原始url
之前执行此操作,但请尝试并查看是否有帮助。
修改强>
在遇到问题的地方尝试这个:
var jsonError:NSError?
let json = NSJSONSerialization.JSONObjectWithData(response, options: nil, error: &jsonError) as NSDictionary {
print(json)
}

switch encodingResult {
case .Success(let upload, _,_):
upload.responseJSON(completionHandler: {response in
if let data = response.result.value as? Dictionary<String, AnyObject>{
if let links = data["links"] as? Dictionary<String, AnyObject> {
if let imgLink = links["image_link"] as? String {
print(imgLink)
}
}
}
})
case .Failure(let error):
print(error)
}
