【问题描述】:
我是安卓开发的新手。我正在使用android studio 开发应用程序。我做过的事情
- 在
MySQL中创建了一个包含两个表的DB。 - 为
GET和POST方法创建了两个单独的api's。 - 成功访问
api's
我现在的成就
- 能够从 GET
api获取GET数据。 - 能够使用 POST
apiPOST数据
我现在要做的事情
我希望我的 api 在线发布,即我想将我的服务部署到服务器并访问它们。此时我能够在服务器上部署服务并访问它们。
现在我希望我的服务 (api's) 得到保护。为此,我搜索了很多文章并找到了两种方法。
- 使用
yii框架。有人告诉我使用它,因为它会自动保护api's。但我不确定它是否有。 - 手动保护
api's
至于1 点,该框架会有所帮助,但它对我来说是新的,需要时间来配合它,因为我已经创建了 Web 服务。
对于2点我得到了一些信息
这两个链接似乎都不错,但链接 1 并没有给我太多关于这方面的信息。
显然我想保护我的两个api's
现在是代码部分
GET_DATA.php
require_once ('config.php');
$sql = "SELECT * FROM users";
$r = mysqli_query($con,$sql);
$result = array();
while($row = mysqli_fetch_array($r)){
array_push($result,array(
'Id'=>$row['Id'],
'Name'=>$row['Name']
));}
echo json_encode(array('users'=>$result));
POST_DATA.php
require_once ('config.php');
$return_arr = array();
$UserId=($_POST['UserId']);
$Latitude=($_POST['Latitude']);
$Longitude=($_POST['Longitude']);
$DateTime=($_POST['DateTime']);
$user_register_sql1 = "INSERT INTO `activity`(`Id`,`UserId`, `Latitude`,`Longitude`,`DateTime`) values (NULL,'".$UserId."','".$Latitude."','".$Longitude."','".$DateTime."')";
mysqli_query ($con,$user_register_sql1);
$row_array['errorcode1'] = 1;
我有一个user class,我从中得到username 和ID
JSONfunctions.java
这个类负责从api获取数据
public static JSONObject getJSONfromURL(String url)
{
String json = "";
JSONObject jsonObject = null;
try
{
HttpClient httpClientt = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse httpResponse = httpClientt.execute(httpGet);
BufferedReader br = new BufferedReader(new InputStreamReader(httpResponse.getEntity().getContent()));
StringBuffer sb = new StringBuffer();
String line = "";
while ((line = br.readLine()) != null) {
sb.append(line);
}
json = sb.toString();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
try
{
jsonObject = new JSONObject(json);
} catch (JSONException e) {
e.printStackTrace();
}
return jsonObject;
}
PutUtility.Java
这个类负责POST方法
public void setParam(String key, String value) {
params.put(key, value);
}
public String postData(String Url) {
StringBuilder sb = new StringBuilder();
for (String key : params.keySet()) {
String value = null;
value = params.get(key);
if (sb.length() > 0) {
sb.append("&");
}
sb.append(key + "=" + value);
}
try {
// Defined URL where to send data
URL url = new URL(Url);
URLConnection conn = null;
conn = url.openConnection();
// Send POST data request
httpConnection = (HttpURLConnection) conn;
httpConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
httpConnection.setRequestMethod("POST");
httpConnection.setDoInput(true);
httpConnection.setDoOutput(true);
OutputStreamWriter wr = null;
wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(sb.toString());
wr.flush();
BufferedReader in = new BufferedReader(
new InputStreamReader(httpConnection.getInputStream()));
String inputLine;
response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally {
try {
reader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return response.toString();
}
MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
_latitude = (TextView)findViewById(R.id.latitude);

}
new ServiceLogin().execute(UserId, Latitude, Longitude, DateTime);
}
});
// Download JSON file AsyncTask
new DownloadJSON().execute();
}
// Download JSON file AsyncTask
private class DownloadJSON extends AsyncTask<Void, Void, Void>
{
@Override

super.onPreExecute();
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMessage("Fetching Users....!");
progressDialog.setCancelable(false);
progressDialog.show();

try
{
JSONObject jobj = new JSONObject(jsonObject.toString());
// Locate the NodeList name
jsonArray = jobj.getJSONArray("users");
for(int i=0; i<jsonArray.length(); i++)
{
jsonObject = jsonArray.getJSONObject(i);
Users user = new Users();
user.setId(jsonObject.optString("Id"));
user.setName(jsonObject.optString("Name"));
users.add(user);
userList.add(jsonObject.optString("Name"));
}
} catch (JSONException e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void args)
{
// Locate the spinner in activity_main.xml
Spinner spinner = (Spinner)findViewById(R.id.spinner);
// Spinner adapter
spinner.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_spinner_dropdown_item, userList));
// Spinner on item click listener
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
textViewResult = (TextView)findViewById(R.id.textView);
// Set the text followed by the position
textViewResult.setText("Hi " + users.get(position).getName() + " your ID is " + users.get(position).getId());
UserId = String.valueOf(users.get(position).getId());
progressDialog.dismiss();
_latitude.setText("");
_longitude.setText("");
Latitude = null;
Longitude= null;
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
textViewResult.setText("");
}
});
}
}
由于我是新手,所以我不知道在 php 脚本中做什么以及在我的 android 代码中做什么:(。如果有人可以指导我或给我一个教程,那将非常有帮助跟随。
任何帮助将不胜感激。

你可以通过 SSL/TLS 连接来保护你的 restful api,试试这个:stackoverflow.com/questions/15157238/…
