これは Android アプリの一部です... .$_POST['varname'] を使用せずに mysql_query を指定すると、php スクリプトが機能します。ユーザー定義可能なさまざまなパラメーターを使用してアプリに検索機能を追加するために、httpget が呼び出されたときにアプリから渡される値から、PHP スクリプトでクエリを作成しようとしています... PHP スクリプトの行は次のようになります:
$result = mysql_query("SELECT * FROM businessdata WHERE '"
. $_POST['varQuery2']."' = '"
. $_POST['varQuery1']"'")
or die(mysql_error());
次に、メソッドは次のとおりです。
public JSONObject makeHttpRequest(String url, String method,
List<NameValuePair> params, String value, String value2) {
// Making HTTP request
try {
// check for request method
if(method == "POST"){
// request method is POST
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
params.add(new BasicNameValuePair("varQuery2", value));
params.add(new BasicNameValuePair("varQuery1", value2));
HttpPost httpPost = new HttpPost(url);
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}else if(method == "GET"){
// request method is GET
DefaultHttpClient httpClient = new DefaultHttpClient();
params.add(new BasicNameValuePair("varQuery2", value));
params.add(new BasicNameValuePair("varQuery1", value2));
String paramString = URLEncodedUtils.format(params, "UTF-8");
url += "?" + paramString;
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();
}

e.printStackTrace();

} catch (IOException e) {

}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
json = sb.toString();
} catch (Exception e) {

}
