我是android的新手，我尝试将图像文件直接发送到我的服务器上。我不知道该怎么做。我正在使用post方法在我的服务器中使用JAX-RS Restful Web服务。
这是我的代码（Android代码）：
File myFile = new File("/path/to/file.png");
RequestParams params = new RequestParams();
try {
params.put("image", myFile);
UpdateProfilePicToServer(params);
} catch(FileNotFoundException e) {}
private void UpdateProfilePicToServer(RequestParams params) {
// Show Progress Dialog
prgDialog.show();
// Make RESTful webservice call using AsyncHttpClient object
AsyncHttpClient client = new AsyncHttpClient();
// client.setTimeout(20000);
client.post(URL, params, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
// Hide Progress Dialog
prgDialog.dismiss();
try {
// JSON Object
JSONObject obj = new JSONObject(new String(responseBody));
// When the JSON response has status boolean value assigned with true
if (obj.getBoolean("status")) {
Toast.makeText(context.getApplicationContext(), "Saved", Toast.LENGTH_LONG).show();
}
// Else display error message
else {
profilePic.setImageResource(R.drawable.profile_placeholder);
Toast.makeText(context, obj.getString("msg"), Toast.LENGTH_LONG).show();
}
} catch (JSONException e) {
// TODO Auto-generated catch block
Toast.makeText(context, "Error Occured [Server's JSON response might be invalid]!", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
@Override
public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {
// Hide Progress Dialog
prgDialog.dismiss();
// When Http response code is '404'
if (statusCode == 404) {
Toast.makeText(context, "Requested resource not found", Toast.LENGTH_LONG).show();
}
// When Http response code is '500'
else if (statusCode == 500) {
Toast.makeText(context, "Something went wrong at server end", Toast.LENGTH_LONG).show();
}
// When Http response code other than 404, 500
else {
Log.d("StatusCode", String.valueOf(statusCode));
Toast.makeText(context, "Check your internet connection", Toast.LENGTH_LONG).show();
}
}
});
}
这是我的网络服务代码（Java）：
public String post(@FormParam("accId") String accId, @FormParam("image") File image) throws Exception
{
try {
Statement chkUserStmt = DataAccess.conn.createStatement();
String updatequery = "UPDATE ACCOUNT SET PROFILE_PICTURE = LOAD_FILE('" + image+ "') "
+ "WHERE ACCOUNT_ID = '" + accId + "'";
chkUserStmt.executeUpdate(updatequery);
chkUserStmt.close();
return Utility.respJSON("ImageStore ", true, "Success");
} catch (Exception ex) {
Logger.getLogger(ImageStore.class.getName()).log(Level.SEVERE, null, ex);
}
return Utility.respJSON("ImageStore ", false, "Failure");
}
