我正在使用this脚本尝试将POST数据从我的Android应用程序发送到PHP脚本。但它甚至没有让我运行它由于错误“loginUrl无法解决”。由于其他人似乎已经使用此代码,我是否错过了一些明显的东西?这是代码,但由我改变(通过上面链接的评论看到它):
public void postData() {
URL url;
HttpURLConnection conn;
try{
url=new URL("http://mysite/test.php");
String param="param1=" + URLEncoder.encode("value1","UTF-8")+
"¶m2="+URLEncoder.encode("value2","UTF-8")+
"¶m3="+URLEncoder.encode("value3","UTF-8");
conn=(HttpURLConnection)loginUrl.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setFixedLengthStreamingMode(param.getBytes().length);
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(param);
out.close();
String response= "";
Scanner inStream = new Scanner(conn.getInputStream());
while(inStream.hasNextLine())
response+=(inStream.nextLine());
}
catch(MalformedURLException ex){
Toast.makeText(GameButton.this, ex.toString(), 1 ).show();
}
catch(IOException ex){
Toast.makeText(GameButton.this, ex.toString(), 1 ).show();
}
}
谢谢!
答案 0 :(得分:2)
您已将变量声明为url
,但您尝试将其用作loginUrl
。
在代码中检查这些声明和启动
URL url;
url=new URL("http://mysite/test.php");
当您尝试打开连接时和问题:
conn=(HttpURLConnection)loginUrl.openConnection();
应该是
conn=(HttpURLConnection)url.openConnection();
