ios HTTP POSTを使用した画像とテキストのアップロード
読んでくれてありがとう。
私はiOSが初めてで、iOSでmulti-part form encodingを使用して画像とテキストをアップロードしようとしています。
同等のcurlは、次のようなものです：curl -F "param1=value1" -F "[email protected]" "http://some.ip.address:5000/upload"
上記のcurlコマンドは、予想される正しい応答をJSON.で返します
問題：HTTP POST Bodyの作成中に何か間違ったことをしていることを意味するHTTP 400リクエストを取得し続けます。
私がしたこと：いくつかの参考のために、私は Flickr API iOSアプリ「POSTサイズが大きすぎます！」 および 目的C：HTTP POSTを使用して画像とテキストをアップロードする方法 。しかし、私はHTTP 400を取得し続けています。
ASIHttpRequestを試しましたが、別の問題がありました（コールバックが呼び出されませんでした）。しかし、開発者がライブラリのサポートを停止したと聞いたので、これについてはさらに調査しませんでした： http://allseeing-i.com/ [request_release] ;
誰かが私を助けてくれますか？
以下は、Webサーバーに画像を投稿するためのアプリのコードです。
// Dictionary that holds post parameters. You can set your post parameters that your server accepts or programmed to accept.
NSMutableDictionary* _params = [[NSMutableDictionary alloc] init];
[_params setObject:[NSString stringWithString:@"1.0"] forKey:[NSString stringWithString:@"ver"]];
[_params setObject:[NSString stringWithString:@"en"] forKey:[NSString stringWithString:@"lan"]];
[_params setObject:[NSString stringWithFormat:@"%d", userId] forKey:[NSString stringWithString:@"userId"]];
[_params setObject:[NSString stringWithFormat:@"%@",title] forKey:[NSString stringWithString:@"title"]];
// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = [NSString stringWithString:@"----------V2ymHFg03ehbqgZCaKO6jy"];
// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ
NSString* FileParamConstant = [NSString stringWithString:@"file"];
// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:@""];
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:@"POST"];
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: @"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
for (NSString *param in _params) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"%@\r\n", [_params objectForKey:param]] dataUsingEncoding:NSUTF8StringEncoding]];
}
// add image data
NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0);
if (imageData) {
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"; filename=\"image.jpg\"\r\n", FileParamConstant] dataUsingEncoding:NSUTF8StringEncoding]];

}

// setting the body of the post to the reqeust

[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
// set URL
[request setURL:requestURL];
XJones '答えは魅力的でした。
しかし、彼は変数_params、BoundaryConstant、およびrequestURLについて言及/宣言していません。だから、私はその部分を彼の投稿のアドオンとして投稿することを考えました。それは将来他の人を助けるかもしれません。

以下は、マルチパート形式としてファイルをアップロードするための、私の同様の ネットワークキットライブラリ です。
WebRequest *request = [[WebRequest alloc] initWithPath:@"...documents/create.json"];
// optional attributes
request.delegate = delegate;
request.notificationName = @"NotificationDocumentUploaded";
request.queue = myQueue;
NSMutableData *body = [NSMutableData data];
NSString *boundary = @"TeslaSchoolProjectFormBoundary";
[body appendPartName:@"document[name]" value:@"Test" boundary:boundary];
[body appendPartName:@"document[description]" value:@"This is a description" boundary:boundary];

NSString *bodyLength = [NSString stringWithFormat:@"%lu",(unsigned long)[body length]];
[request addValue:bodyLength forHTTPHeaderField:@"Content-Length"];

delegateを使用して、アップロードの進行状況を通知します。
notificationNameを使用して、リクエストの終了を通知します。
queueを使用して、このリクエストをオペレーションキューに追加し、適切なタイミングで処理されるようにします。
これはSwiftバージョンです。フォームデータを送信したくない場合でも、空のフォーム境界を送信することが重要です。特にFlaskは、ファイルデータが後に続くフォームデータを予期し、最初の境界がない場合はrequest.filesを生成しません。
let composedData = NSMutableData()
// Set content type header
let BoundaryConstant = "--------------------------3d74a90a3bfb8696"
let contentType = "multipart/form-data; boundary=\(BoundaryConstant)"
request.setValue(contentType, forHTTPHeaderField: "Content-Type")
// Empty form boundary
composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
// Build multipart form to send image
composedData.appendData("--\(BoundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
composedData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"image.jpg\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

request.setValue(length, forHTTPHeaderField: "Content-Length")
NSURLConnectionSwift 2.2のクラスを使用して、フォームデータを含む画像をアップロードします。
func uploadImage(){
let imageData = UIImagePNGRepresentation(UIImage(named: "dexter.jpg")!)

let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")
let body = NSMutableData()
// append image data to body
body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(NSString(format:"Content-Disposition: form-data; name=\"file\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
body.appendData(imageData!)
body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
request.HTTPBody = body
do {
let returnData = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
let returnString = NSString(data: returnData, encoding: NSUTF8StringEncoding)
print("returnString = \(returnString!)")
}
catch let error as NSError {
print(error.description)
}
}
}
注：メインスレッドのブロックを回避するために、データのアップロード/ダウンロードにsendAsynchronousRequestではなくsendSynchronousRequestメソッドを常に使用します。ここでは、テスト目的でのみsendSynchronousRequestを使用しました。
