Android, PHP parses JSON array, jsonarray, jsonoject, garbled

Unicode-to-UTF-8, json_encode garbled Solution

I hope this will help passers-...

Some of the small projects need to communicate with the server, which is reflected in the android UI. Therefore, an efficient JSON

Thoughts:

The Code is as follows:

Public jsonarray getphonetopcategory () {string url = base_url + "? Option = gettopcate ";
/* Simulate a browser GET request */httpget request = new httpget (URL); jsonarray = NULL;/* stringbulder and jdk_1.5 are added. The usage is basically the same as that of stringbuffer, but the efficiency is much higher than stringbuffer */stringbuilder sbuilder = new stringbuilder (); try {/* simulate the browser client */httpclient client = gethttpclient ();
/* Obtain the client's response to the browser's request */httpresponse response=client.exe cute (request );
/* Test whether the request is successful */system. out. println (response. getstatusline (). getstatuscode (); If (response. getstatusline (). getstatuscode () == 200) {bufferedreader reader = new bufferedreader (New inputstreamreader (response. getentity (). getcontent (), "UTF-8"); For (string S = reader. readline (); s! = NULL; S = reader. readline () {// s = new string (S. getbytes ("Unicode"), "UTF-8"); sbuilder. append (s);} log. I ("json_str", sbuilder. tostring ());
// This part is worth mentioning. Because I return a two-dimensional array, we need to use the jsonarray string (the content is in the array format) constructor.
// It always appears that the printed Unicode code is a string because the decoding is incorrect. First, you must program the jsonarray object by using the constructor.
// Then, use the getjsonobject method of jsonarray to read the content one by one. In this way, JSON is correctly parsed without printing.
// Is a string of Unicode encoding problems, in addition, nonsense, the client, return JSON page must be UTF-8 encoding, only the UTF-8 supports JSON, if
// Non-UTF-8 encoding, must be converted to other encoding formats in advance to UTF-8 encoding, do not appear garbled or even JSON is empty phenomenon, PHP Other encoding to UTF-8
// You can search for more information on the Internet.
Jsonarray JSON= New jsonarray (sbuilder. tostring ());For (INT I = 0; I <JSON. length (); I ++) {system. out. println (JSON. getjsonobject (I ). getstring ("dname");} // jsonarray jssonarray = JSON. tojsonarray (jssonarray) ;}} catch (exception e) {e. printstacktrace ();} return jsonarray ;}

PHP terminal, code, PHP for UTF-8 encoding, can use Notepad ++ and other conversion encoding method

if($_POST['option']!=''){    switch($_POST['option'])    {        case 'GetTopCate':            $sql='select XX,XXX from XXX where Dpid=0';            $result=mysql_query($sql) or die(mysql_error());            $res=Array();            while($rows=mysql_fetch_assoc($result))            {                $res[]=$rows;            }            echo json_encode($res);            break;    }}

 

I feel that the foundation is not solid. First of all, I don't know the ability to read the JSON format is converted to unicode format. I think it is a encoding problem. I also don't know Java's jsonarray and jsonobject, too many accounts are overdue.
