我将我的数据发送到我的云服务器......这很好用。但我想发送SQlite数据库表中存在的所有数据。我在Map方法下使用Do while循环，但它只发送一行。不完整。
String url = "http://blhc.com:1980/Mob/SendDoc.aspx";
SendDoctors(Context paramContext)
{
this.cont = paramContext;
}
@Override
protected String doInBackground(Void... voids) {
//region Sending
try{
ds = new DataSource(cont);
ds.open();
final Cursor cursor = ds.send();
if(cursor.moveToFirst())
do {
//region Sending Data
StringRequest stringRequest = new StringRequest(Request.Method.POST,url,
new Response.Listener<String>(){
@Override
public void onResponse(String response) {
Toast.makeText(cont,"Uploaded.." ,Toast.LENGTH_SHORT).show();
Log.v("jarvis" ,"Resposce" + response);
}
}
, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Toast.makeText(cont,"Error.." ,Toast.LENGTH_SHORT).show();
error.printStackTrace();
}
}){
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> param = new HashMap<String, String>();
param.put("CELL_NO", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_PHONE_NUM)));
param.put("M_DATE", M_DATE);
param.put("M_TIME", M_TIME);
param.put("EMP_ID", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_EMP_ID)));
param.put("DOC_ID", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_DOC_ID)));
param.put("SA", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_SA)));
param.put("NOTE", "NOTE");
param.put("CO_ID", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_CO_ID)));
param.put("LAT", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_LOC_LAT)));
param.put("LNG", cursor.getString(cursor.getColumnIndex(DatabaseHelper.COL_DA_LOC_LON)));
param.put("USER_ID", String.valueOf(LoginActivity.ID));
return param;
}
};
MySingleton.getmInstance(cont).addToRequestQue(stringRequest);

应用循环。但它显示了一些错误......我超出了限制。
有一件事我必须清除thar在我的网络服务器上Api采用变量而不是数组..现在我知道我清楚我的意思了吗？
注意：我正在使用volley lib将数据发送到服务器。
先谢谢。真的很感谢你的帮助。

以下代码是您从Sqlite获取getData并每次调用volley并命中API的参考：
private void UploadSavedData() {
String selectQuery = "SELECT * FROM " + Constants.TABLE_NAME_COUNT;
db = databaseHelper.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
Log.e("DATA_CHECK","DATA_CHECK");
do {
countEditQuantity(cursor.getString(2),cursor.getString(3)); //calling webservices here
Log.e("DATASQLA",""+cursor.getString(1));
} while (cursor.moveToNext());
}else{
}
}
public void countEditQuantity(final String skuData, final String newQty) {
String url = Constants.EDIT_TAKE_INVENTORY_URL"+dcId+"&sku="+""+skuData+"&new_qty="+""+newQt;
Log.e("URL",""+url);
StringRequest eventoReq = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
Log.e("RESPONSE", response.toString());
if (progressCount <= 1) {
if(databaseHelper.deleteTableCount()){
mProgress.dismiss();
utils.showtoast("All Product Quantity Updated");
progressCount = 0;
getSyncTime();
}
} else {
progressCount--;
}
try {
JSONArray j = new JSONArray(response);
// Parse a json
for (int i = 0; i < j.length(); i++) {
try {
JSONObject obj = j.getJSONObject(0);
String code = String.valueOf(obj.get("code"));
Log.e("CODE", "" + code);
if(code.equals("1")){
}
if(code.equals("0")){
utils.showtoast(""+obj.get("message"));
}
if(code.equals("-2")){
utils.showtoast(""+obj.get("message"));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("Error: ", "" + error.getMessage());
utils.showtoast("Please try again...");
}
});
eventoReq.setRetryPolicy(new DefaultRetryPolicy(
MY_SOCKET_TIMEOUT_MS,
DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
// Añade la peticion a la cola
AppController.getInstance(this).addToRequestQueue(eventoReq);
}

在循环内请求服务器不是一个好的选择。你的循环可以执行1000次或更多次。尝试使用数组或发布数据列表的单个请求。
使用JsonArrayRequest作为您的请求。我接受JSONArray作为参数。来自Volley源代码：
/**
* Creates a new request.
* @param method the HTTP method to use
* @param url URL to fetch the JSON from
* @param jsonRequest A {@link JSONArray} to post with the request. Null is allowed and
* indicates no parameters will be posted along with request.
* @param listener Listener to receive the JSON response
* @param errorListener Error listener, or null to ignore errors.
*/
public JsonArrayRequest(int method, String url, JSONArray jsonRequest,
Listener<JSONArray> listener, ErrorListener errorListener) {
super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
errorListener);
}
@param jsonRequest用{@link JSONArray}发布请求。允许空并且
此构造函数使用JSONArray可用于发布数据。使用您的数据制作JSONArray并发送请求。
修改
像这样创建JSONArray：
JSONObject json1= new JSONObject();
json1.put("key1","value1");
json1.put("key2","value2");
JSONObject json2= new JSONObject();
json2.put("key1","value1");
json2.put("key2","value2");
JSONArray jsonArray = new JSONArray();
jsonArray.put(json1);
jsonArray.put(json2);
发送请求
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.POST, url, jsonArray, new Response.Listener<JSONArray>() {
@Override
public void onResponse(JSONArray response) {
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
}
}) {
@Override
public Map<String, String> getHeaders() throws AuthFailureError {
Map<String, String> headers = new HashMap<>();
return headers;
}
};
