我正在尝试从Android模拟器提交一个表单,但它没有发布。我检查了浏览器中的URL并完成了表单,并将新记录发布到MySQL中,但是从android中却没有。我一直在这里寻找相关的线程,但无法找到我的代码的问题,这就是我所拥有的 (我有互联网和网络访问权限)
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.registration);
Submit= (Button)findViewById(R.id.Submit);
Submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DownloadFilesTask newtask = new DownloadFilesTask();
newtask.execute("http://10.0.2.2:9999/api/registration");
}
});
}
private class DownloadFilesTask extends AsyncTask<String,Void,Boolean> {
@Override
protected void onPreExecute() {
super.onPreExecute();
}
@Override
protected Boolean doInBackground(String... params) {
try {
TextView username,password;
username= (TextView)findViewById(R.id.username);
password=(TextView)findViewById(R.id.password);
URL url = new URL("http://10.0.2.2:9999/api/registration");
HttpURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.connect();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "text/plain");
conn.setRequestProperty("charset", "utf-8");
conn.setDoInput(true);
conn.setDoOutput(true);
ContentValues values= new ContentValues();
values.put("username", username.toString());
values.put("password", password.toString());
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(os,"UTF-8"));
writer.write(String.valueOf(values));
writer.flush();
writer.close();
os.close();
return true;
}
catch (Exception e) {
e.printStackTrace();
return false;
}
}
// @Override
protected void onPostExecute(Boolean result) {
if(result==true)
{
Toast.makeText(Registration.this,"Success",Toast.LENGTH_LONG).show();
}
else
{Toast.makeText(Registration.this,"Failed",Toast.LENGTH_LONG).show();}
}
}
底部的Toast总是失败。正如您从我的代码中看到的,我正在尝试插入用户名和密码。
这是我的logcat

有关如何解决此问题的任何建议?
答案 0 :(得分:0)
首先注释行setDoInput
将您的contenvalues转换为URL
String body = "?username=user&password=password"
并在网址
中写下来conn.getOutputStream().write(body.getBytes("UTF8"));
永远不要在doInBackground中调用这些行:
TextView username,password;
username= (TextView)findViewById(R.id.username);
password=(TextView)findViewById(R.id.password);
永远不要在doInBackground中与UI交互,而是使用onPreExecute和onPostExecute。
body var用于测试,如果你可以获得contenvalues的字节,欢迎你。
不要忘记致电
conn.disconnect();
