java.lang.IllegalStateException 连接到数据库的目标主机不能为空

Question

我正在尝试连接到 localhost/myfile.php在我的电脑上。 PHP文件将数据库数据转换为JSON我想在连接后解析它。当我尝试连接时，我得到

Target host must not be null, or set in parameters. scheme=null, host=null,   
path=10.0.0.9/myfile.php

有什么想法吗？

public void getData(){
    String result = "";
    InputStream isr = null;
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("10.0.0.9/myfile.php");  
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        isr = entity.getContent();
}
catch(Exception e){
        Log.e("log_tag", "Error in http connection "+e.toString());
        resultView.setText("Couldnt connect to database" + e);

Answer 1

您似乎缺少 URI 方案。

尝试使用 new HttpPost("http://10.0.0.9/myfile.php");
