我正在开发用于求职的android应用。因此，如何以PDF或word格式上传我的简历。我可以上传到正确的路径。但PDF无法使用。我已使用base 64方法将图像上传到服务器。在这里，我使用的是base 64方法。我是android和php中的新手。请帮助我，帮助将不胜感激。
用于选择文件
private void getDocument()
{
Intent intent = new Intent();
intent.setType("*/*");
String[] extraMimeTypes = {"*/*"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, extraMimeTypes);
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select File"), PICK_PDF_REQUEST);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (requestCode == PICK_PDF_REQUEST && resultCode == RESULT_OK && intent != null && intent.getData() != null) {
Uri filePath = intent.getData();
String uriString = filePath.toString();
File myFile = new File(uriString);
String path = myFile.getAbsolutePath();
displayName = null;
if (uriString.startsWith("content://")) {
Cursor cursor = null;
try {
cursor = getActivity().getContentResolver().query(filePath, null, null, null, null);
if (cursor != null && cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
BrowsCv.setText(displayName);
}
} finally {
cursor.close();
}
} else if (uriString.startsWith("file://")) {
displayName = myFile.getName();
BrowsCv.setText(displayName);
}
}
}
用于上传文件
private void saveinformation() {
pDialog = new ProgressDialog(getActivity());
pDialog.setMessage("Saving.. Please wait...");
pDialog.setCancelable(false);
pDialog.show();
StringRequest stringRequest = new StringRequest(Request.Method.POST, "https://alot.ae/api/cv_upload.php" ,
new Response.Listener<String>() {
@Override
public void onResponse(String ServerResponse) {
pDialog.dismiss();
try {
JSONObject jsonObject = new JSONObject(ServerResponse);
if (jsonObject.getInt("success") == 0) {
Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
} else if (jsonObject.getInt("success") == 1) {
Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
} else
Toast.makeText(getActivity(), jsonObject.getString("message"), Toast.LENGTH_LONG).show();
} catch (JSONException e) {
e.printStackTrace();
}
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError volleyError) {
pDialog.dismiss();
Toast.makeText(getActivity(), "Some Error Occurred", Toast.LENGTH_LONG).show();
}
}) {
@Override
protected Map<String, String> getParams() {
// Creating Map String Params.
Map<String, String> params = new HashMap<String, String>();
prefs = getActivity().getSharedPreferences(Config.SHARED_PREF_NAME, Context.MODE_PRIVATE);
String userid = prefs.getString("userId","");
params.put("user_id",userid);
params.put("attachment", displayName );
return params;
}
};
RequestQueue requestQueue = Volley.newRequestQueue(getActivity());
requestQueue.add(stringRequest);
}
PHP代码
<?php
if(isset($_POST['user_id']) && $_POST['attachment'] != '' ){
include_once("db_connect.php");
$userid = $_POST['user_id'];
$cv = $_POST['attachment'];
if($userid == '' || $cv == '' )
{
die(json_encode(array("success"=>0,"message"=>"Empty ")));
}else
{
$path1 = "user_cvs/".$userid."_1.pdf";
$file = $userid."_1.pdf";
$sql2 =$con->prepare("UPDATE candidate_profile SET attachment = '$file' WHERE user_id = '$userid'");
if( $sql2->execute())
{
file_put_contents('../../jobs/uploads/'.$path1,base64_decode($cv));
echo(json_encode(array("success"=>1,"message"=>"Data Added successfully!!")));
}
else
{
die("Something Error".$sql."<br>".mysqli_error($con));
}
}
}else{
die(json_encode(array("success"=>0,"message"=>"Empty Request Parameters..!!")));
}
mysqli_close($con);
?>
