从Android到PHP页面的HttpPost请求(参数未传递)
我的PHP代码:从Android到PHP页面的HttpPost请求(参数未传递),php,android,parameters,http-post,Php,Android,Parameters,Http Post,我的PHP代码: <?php $data = 'basic'; if( $_POST["tag"]){ $data = $data.$_POST['tag']; } if( $_GET["tag"]){ $data = $data.$_GET['tag']; } echo $data; ?> 公共JSONObject makeHttpRequest(字符串url、字符串方法、, 列表参数){ //发出HTTP请求 试一试{ //检查请求方法 如果(方法==“POS
<?php
$data = 'basic';
if( $_POST["tag"]){
$data = $data.$_POST['tag'];
}
if( $_GET["tag"]){
$data = $data.$_GET['tag'];
}
echo $data;
?>
公共JSONObject makeHttpRequest(字符串url、字符串方法、,
列表参数){
//发出HTTP请求
试一试{
//检查请求方法
如果(方法==“POST”){
//现在是defaultHttpClient对象
DefaultHttpClient httpClient=新的DefaultHttpClient();
HttpPost HttpPost=新的HttpPost(url);
setEntity(新的UrlEncodedFormEntity(参数));
HttpResponse HttpResponse=httpClient.execute(httpPost);
HttpEntity HttpEntity=httpResponse.getEntity();
is=httpEntity.getContent();
}else if(方法==“GET”){
//请求方法是GET
DefaultHttpClient httpClient=新的DefaultHttpClient();
String paramString=URLEncodedUtils.format(params,“utf-8”);
url+=“?”+参数字符串;
HttpGet HttpGet=新的HttpGet(url);
HttpResponse HttpResponse=httpClient.execute(httpGet);
HttpEntity HttpEntity=httpResponse.getEntity();
is=httpEntity.getContent();
}
}捕获(不支持的编码异常e){
e、 printStackTrace();
}捕获(客户端协议例外e){
e、 printStackTrace();
}捕获(IOE异常){
e、 printStackTrace();
}
//下面是将读取并转换为字符串,然后将其传递给主活动
试一试{
BufferedReader reader=新的BufferedReader(新的InputStreamReader(
is,“iso-8859-1”),8);
StringBuilder str=新的StringBuilder();
字符串strLine=null;
而((strLine=reader.readLine())!=null){
str.append(strLine+“\n”);
}
is.close();
json=str.toString();
}捕获(例外e){
}
//现在,我们将尝试将字符串解析为JSON对象
试一试{
jsonObj=新的JSONObject(json);
}捕获(JSONException e){
}
返回jsonObj;
}
与我在问题中提到的代码相同。它不起作用
