问题描述
我试图从提交Android模拟器一种形式，它没有张贴。我检查了网址在浏览器中完成了表格并发布一个新的记录到MySQL，但在Android事实并非如此。我一直在寻找此相关的线程，但无法找到我的code这个问题是我有什么
（我有互联网和网络访问使用许可）
I am trying to submit a form from android emulator and it is not posting. I checked the URL in the browser and completed the form and it posts a new record into MySQL but from android it doesn't. I have been searching here for related threads but can't find the issue with my code this is what I have (I have internet and network access uses permission)
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();}
}
}
和在底部的吐司总是前进到失败。正如你可以从我的code看到我试图插入一个用户名和密码。
and the Toast at the bottom always goes to fail. As you can see from my code I am trying to insert a username and password.
这是我的logcat

我如何才能解决这个问题有什么建议？
Any suggestions on how I can fix this?
推荐答案
第一注释行setDoInput
first comment the line setDoInput
将您contenvalues像一个网址
Convert your contenvalues like a URL
String body = "?username=user&password=password"
和URL中写
conn.getOutputStream().write(body.getBytes("UTF8"));
和永远，永远不会调用doInBackground内这些行：
And never, never call these lines inside an doInBackground:
TextView username,password;
username= (TextView)findViewById(R.id.username);
password=(TextView)findViewById(R.id.password);
决不会在UI交互doInBackground上preExecute和onPostExecute来代替。
Never interact with UI in doInBackground, use onPreExecute and onPostExecute instead.
正文var是测试，如果你能得到contenvalues字节欢迎你。
The body var is for test, if you can get bytes of contenvalues you are welcome.
不要忘了电话
conn.disconnect();
