大佬教程收集整理的这篇文章主要介绍了如何在Android中将图像上传到服务器？，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在尝试通过相机将图像捕获上传到服务器.服务器发送响应代码= 200但Image不上传到服务器.

private Boolean uploadData() {

    int count = this.forumThreadsB.size();
    for (int i = 0; i < count;="" i++)="" {="" if="" (isphoto)="" message="Uploading Shared Items " +="" (i="" +="" 1)="" +="" "="" of="" "="" +="" count;="" else="" message="Uploading Shared Items " +="" (i="" +="" 1)="" +="" "="" of="" "="" +="" count;="" progresscount="(i" *="" 1000)/count;="">@H_489_14@sqliteForumDAO forumDAO = new sqliteForumDAO(mcontext) ;
                            ForumThreadDTO forumThreadDTO = forumDAO.SELEctThread(this.threadid);
                            if(downloadPath!=null && downloadPath.equalsIgnoreCase("null") && downloadPath.equalsIgnoreCase(""))
                            forumThreadDTo.offlinefilepath = downloadPath;
                            forumDAO.updateThread(forumThreadDTO);


                    }


                } catch (IOException ioeX) {
                    Log.e("SyncUploadDownloadHelper","Upload file Failed: " + ioex.getmessage(),ioeX);
                    //return false;
                } catch (Exception E) {
                    Log.e("SyncUploadDownloadHelper","Upload file Failed: " + e.getmessage(),E);
                    //return false;
                }

                if (i == (this.forumThreadsB.size() - 1)){
                    this.sendStatus = "true";
                    progressCount = 1000;
                    SyncUploadDownloadHelper.this.notifyObservers("SyncUploadDownloadHelper:UploadDataFinish");
                }
                else
                    SyncUploadDownloadHelper.this.notifyObservers("SyncUploadDownloadHelper:UploadData");

                //return true;

    }

    return true;
}

功能：

private String getBoundarymessage(String boundary,Hashtablestem.out.println(key + ": " + value);

       res.append("Content-Disposition: form-data; name=\"").append(key).append("\"\r\n")    
       .append("\r\n").append(value).append("\r\n").append("--").append(boundary).append("\r\n");
      }
      res.append("Content-Disposition: form-data; name=\"").append("file").append("\"; filename=\"").append(fileName).append("\"\r\n") 
      .append("Content-Type: ").append(fileTypE).append("\r\n\r\n");

      return res.toString();
     }

在我的应用程序中我捕获图像并将其保存到数据库.保存图像的路径用于上传图像文件.

最佳答案

我@R_197_11392@：

public class httpClient extends AsyncTaskmultipartentity mpEntity = new multipartentity(
                    httpR_525_11845@ultipartMode.bROWSER_COMPATIBLE);

            mpEntity.addPart("form_file",new FileBody(file,"image/jpeg"));

            httppost.setEntity(mpEntity);

            httpResponse response;
            try {

                response = httpclient.execute(httppost);

                httpentity resEntity = response.getEntity();

                if (resEntity != null) {

                }
                if (resEntity != null) {
                    resEntity.consumeContent();
                }
            } catch (ClientProtocolException E) {
                e.printStackTrace();
            } catch (IOException E) {
                e.printStackTrace();
            }



        }
        return null;
    }

    protected void onPostExecute(Long unused) {
        progressDialog.dismiss();

        ((RunnablE) ctx ).run();

        super.onPostExecute(unused);
    }

    protected void onPreExecute() {
    progressDialog = new ProgressDialog(ctX);
    progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
    progressDialog.setmessage("Загрузка фото...");
    progressDialog.setProgress(0);
    progressDialog.setMax(count);
    progressDialog.show();
    }

}

此代码使用该库：

import org.apache.http.httpentity;
import org.apache.http.httpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.httpPost;
import org.apache.http.entity.mime.httpR_525_11845@ultipartMode;
import org.apache.http.entity.mime.multipartentity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaulthttpClient;
import org.apache.http.util.EntityUtils;
import org.apache.james.mime4j.message.message;
