如何通过用户输入将数据插入服务器数据库?
目前,我从数据库检索数据就像
private void getdatafromphp(){
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/video.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection"+e.toString());
}
//convert response to string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line="0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
//paring data
try{
jArray = new JSONArray(result);
JSONObject json_data=null;
json_data = jArray.getJSONObject(jArray.length()-1);
url=json_data.getString("VideoUrl");
}catch(JSONException e1){
}catch(ParseException e1) {
e1.printStackTrace();
}
}
用这个 php
<?php
mysql_connect("localhost","root","");
mysql_select_db("imammuda");
$sql=mysql_query("select * from Video");
while($row=mysql_fetch_assoc($sql))
$output[]=$row;
print(json_encode($output));
mysql_close();
?>
现在我想将数据插入数据库。怎么办?
我发现sql命令是“插入表(列1,列2)值('value1','value2')”。
这是在 php.ini 中插入常量值。
我想要的是从java那里获取用户的输入,然后将此输入复制到php“value1”中,然后运行php来更新数据库。
currently, i retrieve data from database is like that
private void getdatafromphp(){
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/video.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Log.e("log_tag", "Error in http connection"+e.toString());
}
//convert response to string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
sb = new StringBuilder();
sb.append(reader.readLine() + "\n");
String line="0";
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
//paring data
try{
jArray = new JSONArray(result);
JSONObject json_data=null;
json_data = jArray.getJSONObject(jArray.length()-1);
url=json_data.getString("VideoUrl");
}catch(JSONException e1){
}catch(ParseException e1) {
e1.printStackTrace();
}
}
with this php
<?php
mysql_connect("localhost","root","");
mysql_select_db("imammuda");
$sql=mysql_query("select * from Video");
while($row=mysql_fetch_assoc($sql))
$output[]=$row;
print(json_encode($output));
mysql_close();
?>
now i want insert data into database. how to do that?
I had found the sql command which is "insert into table (column1, column2) values ('value1', 'value2')".
This is insert with constant values which is type in php.
What i want is from java there get input from user then copy this input into php 'value1' after that run the php to update the database.

根据您使用的是 Get 还是 Post,
我假设 GET
了解有关使用 db 的更多信息
更新
要知道正确的请求方法,您可以使用此方法。
现在您可以使用 $req 作为请求变量:
Depending on whether you are using Get or Post
i will assume GET

UPDATE
to know the correct request method you can use this.
now you can use $req as your request variable:
