当我添加 2 个文件时，multipartentity我收到：
07-03 11:37:22.465: W/System.err(1112): java.io.FileNotFoundException: /: 打开失败: EISDIR (是一个目录)
我读过，如果我有同名的目录，可能会发生这种情况，但这里不是这种情况。
07-03 11:37:21.535: D/FilePath(1112): /mnt/sdcard/947808.jpg07-03 11:37:21.535: D/FilePath(1112): /mnt/sdcard/126467-jugra.jpg
我该如何解决这样的异常？
我有以下代码，如下所示：
protected JSONObject doInBackground(String... params) {
JSONObject json1 = null;
JSONParser u = new JSONParser();
photos = new ArrayList<String>();
photos.add(photo1);
photos.add(photo2);
photos.add(photo3);
List<File> f = new ArrayList<File>();
for(String p:photos){
Log.d("FilePath",p);
if (p.equals("")|| p.equals("empty"))f.add(new File(p));
}
json1 = u.getJSONFromUrl(f);
photos.clear();
return json1;
}
public JSONObject getJSONFromUrl(List<File> f) {
if (isOnline()) {
String u = url;
u = u + "?";
try {
// defaultHttpClient
httpClient = HttpClientFactory.getThreadSafeClient();
HttpPost httpPost = new HttpPost(url);
MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
multipartEntity.addPart("action", new StringBody("upload_api"));
for(File fs:f){
multipartEntity.addPart("photo_api[]", new FileBody(fs));
}
//
httpPost.setEntity(multipartEntity);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
Log.d("data is sent", "true");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return null;
} catch (ClientProtocolException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
Log.d("wait", "true");
try {
Log.d("response","response");
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "UTF-8"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
// Log.d("JSON line", line);
sb.append(line + "\n");
}
is.close();
json = sb.toString();
Log.d("JSON", json);
if (json.contains("error:2")) {
return null;
}
try {
jObj = new JSONObject(json);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
return null;
}
// pd.dismiss();
return jObj;
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
return null;
}
// try parse the string to a JSON object
} // else promtError();
// return JSON String
// pd.dismiss();
error();
return null;
