如何將圖像從android http放到遠程服務器上

Question

我已經嘗試使用以下代碼，但無法正常工作

File file= new File(filename);
byte[] data = new byte[(int) file.length()];
FileInputStream fileInputStream = new FileInputStream(file);
URL url = new URL("http://www.example.com/resource");
HttpClient client = new DefaultHttpClient();
HttpPut put= new HttpPut(url);
for (int i = 0; i  pairs = new ArrayList();
pairs.add(new BasicNameValuePair("Data", data));
put.setEntity(new UrlEncodedFormEntity(pairs));

HttpResponse response = client.execute(put);

我無法使用HttpsURLConnection嘗試在服務器上放置數據，但已將其上傳。

Answer 1

設置內容長度后，我可以在HttpURLConnection的幫助下進行HTTP put，如下所示

https.setRequestProperty("Content-Type", "image/jpeg");
https.setRequestProperty("Content-Length", "" + file.length());
