web服務器我查看了相關的幾個問題(例如該代碼張貼了很多,但對我不起作用由於某些原因:How do I add REQUEST values to an HTTP POST method using multipart to upload a file to a PHP server in Android?),並試圖一對夫婦的解決方案,但我的文件在服務器上查看時不能解碼爲jpg。我上傳的iPhone應用程序工作,但現在當我移植到Android我想不出這樣做的正確方法。服務器端是一個asp.net流式文件上傳API。讀取JPG到安卓
這裏是我的base64編碼邏輯:
Bitmap fileToUpload = BitmapFactory.decodeFile(obs.getPhotoLocation());
ByteArrayOutputStream stream = new ByteArrayOutputStream();
fileToUpload.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] image = stream.toByteArray();
String data = Base64.encodeToString(image, true);
new HttpConnection(handler).postBitmap(url.toString(), data);
這裏是postBitmap代碼
HttpPost httpPostBitmap = new HttpPost(url);
httpPostBitmap.addHeader("Content-type", "image/jpg");
httpPostBitmap.addHeader("Connection", "Keep-Alive");
httpPostBitmap.setEntity(new StringEntity(data));
response = httpClient.execute(httpPostBitmap);
轉移前和服務器上的文件是相同的大小,所以我不相信這是傳輸出現問題並且更可能出現編碼問題。
這裏是工作的iOS代碼我試圖端口:
NSURL *uploadUrl = [NSURL URLWithString:FILEUPLOAD_URL];
UIImage *testImage = [Helpers getImageFromPhoto:self.obsToTransmit.observationPhoto];
NSData *imageData = UIImageJPEGRepresentation(testImage, 1.0);
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:@"%d", [imageData length]];
[request addValue:@"image/jpg" forHTTPHeaderField:@"Content-type"];
[request setHTTPMethod:@"POST"];
[request addValue:msgLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:imageData];
theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
感謝一大堆! 斯科特
