【中文标题】在android中将多个图像上传到服务器的最快方法【英文标题】：Fastest Way to Upload Multiple Image to Server in android 【发布时间】：2015-11-25 12:02:56 【问题描述】：我有多个图像要上传到服务器，我有一种方法可以将单个图像上传到服务器。现在我正在使用这种方法通过为每个图像创建循环来发送多个图像。
有没有最快的方法将多张图片发送到服务器？提前谢谢...
public int imageUpload(GroupInfoDO infoDO)
ObjectMapper mapper = new ObjectMapper();
int groupId = 0;
try
Bitmap bm = BitmapFactory.decodeFile(infoDO.getDpUrl());
String fileName = infoDO.getDpUrl().substring(
infoDO.getDpUrl().lastIndexOf('/') + 1,
infoDO.getDpUrl().length());
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bm.compress(CompressFormat.JPEG, 75, bos);
byte[] data = bos.toByteArray();
HttpClient httpClient = new DefaultHttpClient();
HttpPost postRequest = new HttpPost(
"http://192.168.1.24:8081/REST/groupreg/upload");
ByteArrayBody bab = new ByteArrayBody(data,
"application/octet-stream");
MultipartEntity reqEntity = new MultipartEntity(
HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("uploadFile", bab);
reqEntity.addPart("name", new StringBody(fileName));
reqEntity.addPart("grpId", new StringBody(infoDO.getGlobalAppId()
+ ""));
postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK)
HttpEntity httpEntity = response.getEntity();
String json = EntityUtils.toString(httpEntity);
Map<String, Object> mapObject = mapper.readValue(json,
new TypeReference<Map<String, Object>>()
);
if ((mapObject != null)
&& (mapObject.get("status").toString()
.equalsIgnoreCase("SUCCESS")))
groupId = (Integer.valueOf(mapObject.get("groupId")
.toString()));
catch (Exception e1)
e1.printStackTrace();
Log.e("log_tag", "Error in http connection " + e1.toString());
return groupId;
【问题讨论】：
顺便说一句，这也取决于您的服务器。这样上传需要花费多少时间？现在可以用了吗？ 感谢您的回复。单个图像从服务器获得响应需要至少 10 秒。 【参考方案1】：使用排球
private void uploadMultipleImage()
dialog = ogressDialog.show(WhatsappUpload.this,"","Loading...",false);
String str[] = new String[MainActivity.bitmaps.size()];
for(int i=0;i<MainActivity.bitmaps.size();i++)
str[i] = getStringImage(MainActivity.bitmaps.get(i));
imgs = TextUtils.join(",",str);
// Log.d("Sid","Join : " + TextUtils.join(",",str));
String urlImages = "http://192.168.100.13/iupload/test_image.php";
StringRequest stringRequest = new StringRequest(Request.Method.POST, urlImages,
new Response.Listener<String>()
@Override
public void onResponse(String response)
dialog.hide();
Log.d("Sid","Response : " + response.toString());
try
JSONObject object = new JSONObject(response.toString());
Toast.makeText(getApplicationContext(),object.getString("msg"),Toast.LENGTH_SHORT).show();
catch (JSONException e)

String cap = !TextUtils.isEmpty(edtCaption.getText().toString()) ? edtCaption.getText().toString() : "Default Captions!";
Map<String,String> params = new Hashtable<String, String>();
params.put("captions",cap);
params.put("images", imgs);
return params;
;
RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
requestQueue.add(stringRequest);
public String getStringImage(Bitmap bmp)
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] imageBytes = baos.toByteArray();
String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT);
return encodedImage;

【参考方案2】：试试这个代码。这对于上传一张或两张或三张图片很有用，并使用httpmime-4.2.1.jar

【参考方案3】：有很多方法可以将更多图像上传到服务器。一种可能包括两个库：apache-mime4j-0.6.jar 和 httpmime-4.0.1.jar。然后创建您的 java 主代码：

runOnUiThread(new Runnable()
public void run()
try

res.setText("n Response from server : n " + response_str);
Toast.makeText(getApplicationContext(),"Upload Complete. Check the server uploads directory.", Toast.LENGTH_LONG).show();
catch (Exception e)
e.printStackTrace();
);
catch (Exception ex)
Log.e("Debug", "error: " + ex.getMessage(), ex);
现在你的布局：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_
android:layout_
>
<TextView
android:layout_
android:layout_
android:text="Multiple File Upload from CoderzHeaven"
/>
<Button
android:id="@+id/Button01"
android:layout_
android:layout_
android:text="Get First File">
</Button>
<Button
android:id="@+id/Button02"
android:layout_
android:layout_
android:text="Get Second File">
</Button>
<Button
android:id="@+id/upload"
android:layout_
android:layout_
android:text="Start Upload">
</Button>
<TextView
android:id="@+id/tv"
android:layout_
android:layout_
android:text="Selected File path : "
/>
<TextView
android:id="@+id/res"
android:layout_
android:layout_
android:text=""
/>
</LinearLayout>
当然，在清单中包含互联网权限：
<uses-permission android:name="android.permission.INTERNET" />
然后瞧。无论如何，我在我的情况下遵循了这个示例：http://www.coderzheaven.com/2011/08/16/how-to-upload-multiple-files-in-one-request-along-with-other-string-parameters-in-android/ 尝试在那里查看.. 有 4 种方法可以上传多个文件。看看你喜欢哪个
【讨论】：
我也喜欢 HttpEntity，不过现在已经弃用了。 如何添加这些库？？请帮忙 @Md.AshikurRahman 来自build.gradle。以上是关于在android中将多个图像上传到服务器的最快方法的主要内容，如果未能解决你的问题，请参考以下文章
