Send 'you' to show Pw =

Echo base64_decode ('pw = '); // output?
That is to say, when sending, 'you' has changed '? '

Echo base64_decode ('pw = '); // output?
That is to say, when sending, 'you' has changed '? '


The decode output is indeed '? '

I think it should be about java and php encoding.
Because if I use php to store Chinese characters in the variables, it is okay to query mysql.

Do you know how to change the encoding in php. ini?

Echo base64_decode ('pw = '); // output?
That is to say, when sending, 'you' has changed '? '

It seems that it may be wrong when sending the message. no matter what the Chinese word is, Pw = if both words are, Pz8 =

The request is obtained in this way.
The addHeader in is meaningless.

List
 
   listParams = new ArrayList
  
   ();if (params != null){for (String name : params.keySet()){listParams.add(new BasicNameValuePair(name, params.get(name)));}}try{UrlEncodedFormEntity entity = new UrlEncodedFormEntity(listParams);HttpPost request = new HttpPost(url);request.addHeader("charset", HTTP.UTF_8);request.setEntity(entity);return request;
  
 

This? That? You may have encountered encoding conversion problems, mark

Okay, thank you.

UrlEncodedFormEntity entity = new UrlEncodedFormEntity (listParams); // change UrlEncodedFormEntity entity = new UrlEncodedFormEntity (listParams, HTTP.UTF-8 );

If possible, comment it out.
