ANDROID-通过VOLLEY将列表发送到PHP [英] ANDROID - send List to PHP via VOLLEY
问题描述
您好,我有一个名为StudentBATCH_LIST的列表,我使用以下命令从csv中填充了该内容:
Hello I have a List named StudentBATCH_LIST that I populated with the contents from a csv using:
File csvFILE = new File(getFILE_PATH());
try {
CSVReader csvREAD = new CSVReader(new
FileReader(csvFILE.getAbsolutePath()));
String[] csvLINE;
int skip = 0;
while((csvLINE = csvREAD.readNext())!=null)
{
if(skip > 0)//becasue first line is column headers
{
String PARAM_USER_ID = csvLINE[0];
String PARAM_STUD_FIRSTNAME = csvLINE[1];
String PARAM_STUD_LASTNAME = csvLINE[2];
String PARAM_STUD_MIDDLENAME = csvLINE[3];
String PARAM_STUD_EMAIL = PARAM_USER_ID+EMAIL_S;
AdminAddStudentBATCH_CONFIG STUD_OBJECT = new AdminAddStudentBATCH_CONFIG(PARAM_USER_ID,
PARAM_STUD_FIRSTNAME,
PARAM_STUD_LASTNAME,
PARAM_STUD_MIDDLENAME,
PARAM_STUD_EMAIL);
StudentBATCH_LIST.add(STUD_OBJECT);
}
else
{
skip ++;
}
}
} catch (FileNotFoundException e) {
volleyErrorClass.catchInvalidResponse(e.toString(),AdminAddStudentBATCH.this);
} catch (IOException e) {
volleyErrorClass.catchInvalidResponse(e.toString(),AdminAddStudentBATCH.this);
} catch (JSONException e) {
volleyErrorClass.catchInvalidResponse(e.toString(),AdminAddStudentBATCH.this);
} catch (IndexOutOfBoundsException e) {
volleyErrorClass.catchInvalidResponse(e.toString(),AdminAddStudentBATCH.this);
}
我想知道如何通过凌空传递此列表到PHP.我该怎么做?另外,我该如何在PHP中对此进行解码.
I want to know how do I pass this List to PHP with volley. How do I do it? Also how do I decode this in PHP.
无论如何,列表中值的标签是 USER_ID
, STUD_FIRSTNAME
, STUD_LASTNAME
, STUD_MIDDLENAME
, STUD_EMAIL
Anyway the tags of the values in the List are
USER_ID
,
STUD_FIRSTNAME
,
STUD_LASTNAME
,
STUD_MIDDLENAME
,
STUD_EMAIL
推荐答案
出于您的应用程序的目的,我将StudentBATCH_LIST转换为JSON数组,然后在您的Web api上反序列化该数组.
For the purpose of your application, I'd convert the StudentBATCH_LIST to JSON array, and then deserialize that array on your web api.
以下是简单的步骤:
步骤1.将Volley和GSON依赖项添加到应用程序级别的build.gradle文件中:
dependencies {
...
compile 'com.android.volley:volley:1.1.0'
compile 'com.google.code.gson:gson:2.8.2'
}
步骤2.使用GSON将列表转换为JSON数组:
String studentBatchListString = new Gson().toJson(students);
第3步.将studentBatchListString发布到您的网络api(发送到PHP")
String url = "http://yourdomain.com/post.php";
StringRequest postRequest = new StringRequest(Request.Method.POST, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// response
Log.d("Response", response);
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
// error
Log.d("Error.Response", response);
}
}
) {
@Override
protected Map<String, String> getParams() {
Map<String, String> params = new HashMap<String, String>();
params.put("students_batch_list", studentBatchListString);
return params;
}
};
queue.add(postRequest);
第4步.在PHP方面反序列化:
$content = $_POST['students_batch_list'];
$json = json_decode($content, true);
foreach ($json as $key => $value) {
$firstname = $value["firstname"];
$lastname = $value["lastname"];
// perform other actions.
}
