android,与PHP通信,返回JSON

android开发, web服务器端开发 by

小项目需要读取数据库,刚好手头有服务器,处于某些考虑,还是想远程读数据,所遇异常

Logcat异常:

SingleClientConnManager(411): Invalid use of SingleClientConnManager: connection still allocated.

Make sure to release the connection before allocating another one.

request time failed: java.net.SocketException: Address family not supported by protocol

基本思路就是,通过一个按钮监听事件,利用HttpClient来实现交互。<关于更多HttpClient点击此处:穿梭查看>

上核心代码:

 

PHP代码:

<?php

$array=array(‘title’=>’name’,’value’=>’doooger’);

json_encode($array);

?>

 

复制代码
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //TextView homeContext=new TextView(this);
        setContentView(R.layout.tel);
        Button btn = (Button)findViewById(R.id.getPhpJson);
        btn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
            // TODO Auto-generated method stub
            EditText edit = (EditText)findViewById(R.id.typeId);
            Log.i(Tag, "eeeeeeee");
            String url = "http://www.test.com:80/an/index.php?type=1";
            getServerJsonDataWithNoType(url,edit);
            }
            });
    }

-----------------------------------------------------------------------------------------------------------------

public void getServerJsonDataWithNoType(String url,EditText editText)
    {
    int res = 0;
    HttpClient client = new DefaultHttpClient();
    StringBuilder str = new StringBuilder();
    HttpGet httpGet = new HttpGet(url);
    try
    {
        HttpResponse httpRes = client.execute(httpGet);
        httpRes = client.execute(httpGet);
        res = httpRes.getStatusLine().getStatusCode();
        if(res == 200)
        {
            BufferedReader buffer = new BufferedReader(new InputStreamReader(httpRes.getEntity().getContent()));
            for(String s = buffer.readLine(); s != null ; s = buffer.readLine())
            {
            str.append(s);
            }
            //String out = EntityUtils.toString(httpRes.getEntity().getContent(), "UTF-8");
            //StringBuilder sb = new StringBuilder()
            Log.i(Tag,str.toString());
            try
            {
            //JSONObject json = new JSONObject(str.toString()).getJSONObject("content");
            JSONObject json = new JSONObject(str.toString());
            String title = json.getString("title");
            Log.i(Tag,title);
            int id = json.getInt("id");
            String value = json.getString("value");
            Log.i(Tag,value);
            editText.setText("Title:" + title + " ID:" + id + " Value:" + value);
            }
            catch(JSONException e)
            {
            Log.i(Tag, e.getLocalizedMessage());
            //buffer.close();
            e.printStackTrace();
            }
        }
        else
            {
            Log.i(Tag, "HttpGet Error");
            }
        }
        catch(Exception e)
            {
            Log.i(Tag, "Exception");
            }
    
    }
复制代码

 

解决办法:

url没拼对,用的是本地的虚拟服务器,android的本地ip对应的是10.0.2.2,所以url应该如下拼写:<貌似只能用IIS的默认网站进行交互,如果谁知道怎么用hosts拦截DNS解析用域名访问的方法欢迎留言>

String url = “http://10.0.2.2/tell/index.php?type=1“;

这样,就没有问题了!

PS:IIS加载PHP模块需要两步:

1、加载php5isapi.dll

2、iis->对应网站->主目录->配置->映射加载对应的php5isapi.dll
