请教一个关于同时上传图片和文字的例子

Question

如题，请教一个用httpclient通过post数据发送图片和文字的例子（要同时发送）
分不够可以再加

Answer 1

multipart 文件上传标准 既可以传文字 又可以传文件内容

Answer 2

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (resultCode == RESULT_OK) {
     EditText et = (EditText)findViewById(R.id.txtMemo);
     try{
     //获取虚幻中的文件路径
     Uri uri = data.getData();
        String[] proj = { MediaStore.Images.Media.DATA };   
                Cursor actualimagecursor = managedQuery(uri,proj,null,null,null);   
                int actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);   
                actualimagecursor.moveToFirst();   
                String img_path = actualimagecursor.getString(actual_image_column_index);
                
                //获取选中的文件
                File file = new File(img_path);                //从基站获取当前地理位置信息
                TelephonyManager tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
          GsmCellLocation gcl = (GsmCellLocation) tm.getCellLocation();
                
          int cid = 0;
     int lac = 0;
     int mcc = 0;
     int mnc = 0;
         
     if(gcl != null){
     cid = gcl.getCid();
     lac = gcl.getLac();
     mcc = Integer.valueOf(tm.getNetworkOperator().substring(0, 3));
     mnc = Integer.valueOf(tm.getNetworkOperator().substring(3, 5));
    
     //首先创建HttpPost对象
     HttpPost post= new HttpPost("http://192.168.1.123:8011/SetTrackData.aspx?op=GetImage");
     MultipartEntity entity = new MultipartEntity();
    
     //设置POST参数
     entity.addPart("CID",new StringBody(cid + ""));
     entity.addPart("LC",new StringBody(lac + ""));
     entity.addPart("MMC",new StringBody(mcc + ""));
     entity.addPart("MNC",new StringBody(mnc + ""));
     entity.addPart("IMEI",new StringBody(tm.getDeviceId()));
     entity.addPart("IRM",new StringBody(et.getText() + ""));
     entity.addPart("file",new FileBody(file));
    
     HttpClient client = new DefaultHttpClient();
     HttpResponse response=client.execute(post);
     }
    
     ContentResolver cr = this.getContentResolver(); 
     Bitmap bitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));
     ImageView iv = (ImageView)findViewById(R.id.iv01);
     iv.setImageBitmap(bitmap);  
    
     et.setText(img_path);
     }
     catch(Exception e){
     et.setText(e.getMessage());
     }
     }
     super.onActivityResult(requestCode, resultCode, data);
    }
这是上传代码     private void GetImage()
    {
        HttpFileCollection upFiles = Request.Files;
        string backName = Request.Form["FileName"] ?? "" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".jpg";
        string path = Server.MapPath(@"~\DataImages\") + backName;
        string result = "恢复数据库失败。";        if (upFiles.Count != 0)
        {
            // 只取第 1 个文件
            HttpPostedFile hpf = upFiles[0];
            if (hpf != null && hpf.ContentLength > 0)
            {
                // flash 会自动发送文件名到 Request.Form["fileName"]
                hpf.SaveAs(path);                if (File.Exists(path))
                {
                    string sqlCmd = "INSERT INTO [ImageData]([ImagePatch],[SendImageIMEI],[SendImageLng],[SendImageLat],[ImageReMark])";
                    sqlCmd += "Values(@ImagePatch,@SendImageIMEI,@SendImageLng,@SendImageLat,@ImageReMark)";                    CellInfo ci = new CellInfo();
                    GeoLocation gl = new GeoLocation();
                    OtherMethod om = new OtherMethod();                    ci.CID = Request.Form["CID"] ?? "";
                    ci.LAC = Request.Form["LC"] ?? "";
                    ci.MCC = Request.Form["MMC"] ?? "460";
                    ci.MNC = Request.Form["MNC"] ?? "0";                    string jsonData = gl.GenerateRequestJson(ci);
                    string resultData = om.httpSendData("http://www.google.com/loc/json", jsonData);
                    int s = resultData.IndexOf(':');
                    int e = resultData.LastIndexOf(',');
                    LocationObject lo = gl.GetObjData(resultData.Substring(s + 1, e - s));                    if (!string.IsNullOrEmpty(lo.longitude))
                    {
                        string[,] parms = {
                                   {"ImagePatch",path},
                                   {"SendImageIMEI",Request.Form["IMEI"] ?? ""},
                                   {"SendImageLng",lo.longitude},
                                   {"SendImageLat",lo.latitude},
                                   {"ImageReMark",Server.HtmlDecode(Request.Form["IRM"] ?? "")}
                              };                        
                    DBOperation dbo = new DBOperation();
                    dbo.RunSql(sqlCmd, parms);
                    }
                }
            }
        }
    }
这是接收端代码，就是死活能接收参数不能接收文件
