java - 如何在网络服务中发送电话号码并在android中接收请求

Question

我在通过 http 客户端将数据发送到 post 方法时遇到麻烦。我想将任何电话号码发送到网络服务并接收请求。

这是我的 SignUp.java:-

public class SignUp extends AppCompatActivity implements View.OnClickListener {

TextView tv;
Button sign_up;
EditText et;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.sign_up);

    tv = (TextView)findViewById(R.id.sign_up);
    sign_up = (Button)findViewById(R.id.login_buttton);
    et = (EditText)findViewById(R.id.sign_up_editText);

    tv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(SignUp.this, LoginActivity.class);
            startActivity(intent);
        }
    });

    sign_up.setOnClickListener(this);
}
public void onClick(View v){

    validateForm();

/*     if(et.getText().toString().isEmpty()){
        Toast.makeText(SignUp.this,"Please Fill Contect Nuumber",Toast.LENGTH_LONG).show();
    }
    else{
        postSignUpData();
    }*/
}

public void postSignUpData(){
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();

}
private static boolean isValidPhoneNumber(String mobile) {
    String regEx = "^[0-9]{10}$";
    return mobile.matches(regEx);
}
private void  validateForm(){
    String mobile = et.getText().toString();

    if(isValidPhoneNumber(mobile)){
        requestForSMS();
    }
    else {
        Toast.makeText(SignUp.this,"Please enter valid mobile number",Toast.LENGTH_LONG).show();
    }
}

private void requestForSMS(){

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://opencart.codeniques.com/shopping/?route=feed/web_api/registertele&key=test123$");
    try{
        List<NameValuePair> nameValuePairs = new ArrayList<>(1);
        nameValuePairs.add(new BasicNameValuePair("number",et.getText().toString()));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        int status = response.getStatusLine().getStatusCode();
        if(status==200){
            HttpEntity entity = response.getEntity();
            String data = EntityUtils.toString(entity);

            JSONObject jsonObject = new JSONObject(data);
            Toast.makeText(SignUp.this,"Value of json object"+jsonObject,Toast.LENGTH_LONG).show();
        }
        else{
            Toast.makeText(SignUp.this,"GO to else",Toast.LENGTH_LONG).show();
        }
        //String str = inputStreamToString(response.getEntity().getContent()).toString();
    //    Toast.makeText(SignUp.this,"Str value "+str,Toast.LENGTH_LONG).show();
       // HttpResponse response = httpclient.execute(httppost);
    }catch (IOException |JSONException e){
        Log.e("Error :",e.getMessage() );
    }
}
private StringBuilder inputStreamToString(InputStream is){
    String line = "";
    StringBuilder total = new StringBuilder();
    // Wrap a BufferedReader around the InputStream
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));
    // Read response until the end
    try {
        while ((line = rd.readLine()) != null) {
            total.append(line);
        }
    } catch (IOException  e) {
        e.printStackTrace();
    }
    // Return full string
    return total;
}

}

Answer 1

这不是您的代码问题。您使用的是最低 api 级别 2.3 等。因此您需要在 asynctask 中执行网络操作或在代码之前使用以下代码以避免异常

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy = 
    new StrictMode.ThreadPolicy.Builder().permitAll().build();      
        StrictMode.setThreadPolicy(policy);
 }
