web服务器我查看了相关的几个问题(例如该代码张贴了很多,但对我不起作用由于某些原因:How do I add REQUEST values to an HTTP POST method using multipart to upload a file to a PHP server in Android?),并试图一对夫妇的解决方案,但我的文件在服务器上查看时不能解码为jpg。我上传的iPhone应用程序工作,但现在当我移植到Android我想不出这样做的正确方法。服务器端是一个asp.net流式文件上传API。读取JPG到安卓

这里是我的base64编码逻辑:

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); 

这里是postBitmap代码

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); 

转移前和服务器上的文件是相同的大小,所以我不相信这是传输出现问题并且更可能出现编码问题。

这里是工作的iOS代码我试图端口:

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]; 

感谢一大堆! 斯科特

尝试使用的Base64编码图像以字符串和在服务器的另一端,通过解码它的Base64的字符串改变为图像。检查链接[http://developer.android.com/reference/android/util/Base64.html] [1]

[1]:http://developer.android.com/reference/android/util/Base64.html这是从2.2支持。我们还为不到2.2版本的设备提供Base64.java。
