安卓：上传图片和JSON使用MultiPartEntityBuilder [英] Android : upload Image and JSON using MultiPartEntityBuilder

问题描述

我尝试将数据上传到服务器，我的数据包含多张图片，大 JSON ，在它之前，我尝试使用与转换图像发送到字符串的base64 并发送我的另一个数据和图像，我之前已经转换与 JSON ，但我面对的问题内存不足在这里，所以我读的解决方案，说我一定要尝试使用 MultipartEntityBuilder 之一。 我仍然混乱，不知道如何与 MultiPartEntityBuilder 做到这一点，是否有任何人能帮助我与 MultiPartEntityBuilder ？这是我的code：

I try to upload data to server, my data containing multiple images and large JSON, before it, I Try to send with convert image to string using base64 and send my another data and image that I've convert before with JSON, but I face Problem OutOfMemory here, so I read one of solutions that said I must to try using MultipartEntityBuilder. I still confusing and not understand how to do it with MultiPartEntityBuilder, Is there anyone can help me the way to do it with MultiPartEntityBuilder? this is my code :

    try{
    //membuat HttpClient
    //membuat HttpPost
    HttpPost httpPost= new HttpPost(url);
    SONObject jsonObjectDP= new JSONObject();
    System.out.println("file audio "+me.getModelDokumenPendukung().getAudio());
    jsonObjectDP.put("audio_dp",MethodEncode.EncodeAudio(me.getModelDokumenPendukung().getAudio()));
    jsonObjectDP.put("judul_audio",me.getModelDokumenPendukung().getJudul_audio());
    jsonObjectDP.put("ket_audio",me.getModelDokumenPendukung().getKet_audio());
    JSONArray ArrayFoto= new JSONArray();

    //This loop For my multiple File  Images
    List<ModelFoto>ListFoto=me.getModelDokumenPendukung().getListFoto();
    for (int i=0; i<ListFoto.size();i++) {
        JSONObject jsonObject= new JSONObject();
        jsonObject.put("foto", ListFoto.get(i).getFile_foto());
        jsonObject.put("judul_foto", ListFoto.get(i).getJudul_foto());
        jsonObject.put("ket_foto", ListFoto.get(i).getKet_foto());
        ArrayFoto.put(jsonObject);

    }

    JSONObject JSONESPAJ=null;
     JSONESPAJ = new JSONObject();
     JSONObject JSONFINAL = new JSONObject();
            JSONESPAJ.put("NO_PROPOSAL",me.getModelID().getProposal());
            JSONESPAJ.put("GADGET_SPAJ_KEY",me.getModelID().getIDSPAJ());
            JSONESPAJ.put("NO_VA",me.getModelID().getVa_number());
            JSONESPAJ.put("Dokumen_Pendukung",jsonObjectDP);

            JSONFINAL.put("ESPAJ", JSONESPAJ);
            JSONFINAL.put("CLIENT", "ANDROID");
            JSONFINAL.put("APP", "ESPAJ");

            MultipartEntityBuilder multiPartEntityBuilder= MultipartEntityBuilder.create();
    multiPartEntityBuilder.addPart("ESPAJ",JSONFINAL.toString());

    httpPost.setEntity(multiPartEntityBuilder.build());

    HttpResponse httpResponse = httpclient.execute(httpPost);


    inputStream = httpResponse.getEntity().getContent();
        if(inputStream != null)
        result = convertInputStreamToString(inputStream);
    else
        result = "Did not work!";
}catch(OutOfMemoryError e){
      Log.e("MEMORY EXCEPTION: ", e.toString());
} catch(ConnectTimeoutException e){
    Log.e("Timeout Exception: ", e.toString());
} catch(SocketTimeoutException ste){    
    Log.e("Timeout Exception: ", ste.toString());
} catch (Exception e) {
//    Log.d("InputStream", e.getLocalizedMessage());
}
private static String convertInputStreamToString(InputStream inputStream) throws IOException{
    BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));
    String line = "";
    String result = "";
    while((line = bufferedReader.readLine()) != null)
//      hasil=line;
        result += line;

    inputStream.close();
    return result;

}   

有没有任何人能帮助我，教，并告诉我如何使用MultiPartEntityBuilder发送JSON和图片？

is there anyone can help me to teach and tell me how to send JSON and Image using MultiPartEntityBuilder?

推荐答案

要送你需要使用二进制数据 addBinaryBody 的方法 MultipartEntityBuilder 。附加的示例：

To send binary data you need to use addBinaryBody method of MultipartEntityBuilder. Sample of attaching:

import org.apache.http.entity.ContentType;
import org.apache.http.entity.mime.MultipartEntityBuilder;
//Image attaching
MultipartEntityBuilder multipartEntity = MultipartEntityBuilder.create();
File file;
multipartEntity.addBinaryBody("someName", file, ContentType.create("image/jpeg"), file.getName());
//Json string attaching
String json;
multipartEntity.addPart("someName", new StringBody(json, ContentType.TEXT_PLAIN));

然后进行申请和往常一样：

Then make request as usual:

HttpPut put = new HttpPut("url");
put.setEntity(multipartEntity.build());
HttpResponse response = client.execute(put);
int statusCode = response.getStatusLine().getStatusCode();
