Pass Array & Multidimensional Array from Android to PHP

I have my Android Java code that have to pass some array and some multidimensional array to the PHP Server. Unfortunately, I don't have the access to the PHP Server.

我有我的Android Java代码，必须将一些数组和一些多维数组传递给PHP Server。不幸的是，我没有访问PHP服务器的权限。

Here's the PHP Server API :

这是PHP Server API：

$result= array(
    "username" => "admin",
    "password" => "admin",
    "hobbies" => array(
                "1" => "science"
     ),
    "skills" => array(
                "1" => array(
                        "Boxing" => "Yes"
                    )
     )
);

Here's my Android Java Code :

这是我的Android Java代码：

final String hobbies[] = {"science"};
final String skills[][] = {{"Boxing"},{"Yes"}};

@Override
protected Map<String, String> getParams() {
                Map<String, String> jParams= new HashMap<String, String>();

JSONArray arrHobbies = new JSONArray();
JSONArray arrSkills = new JSONArray();
arrHobbies.put(hobbies[0]);
arrSkills.put(skills[0][0]);

jParams.put("username", "admin");
jParams.put("password", "admin");
jParams.put("hobbies",arrHobbies.toString();
jParams.put("skills",arrSkills.toString();

return jParams;
}};

Then, I use this code to see how the data've been sent.

然后，我使用此代码来查看数据是如何发送的。

Log.d("Response : ", jParams.toString());

It shows this on the Android Log :

它在Android日志中显示：

{password=admin, username=admin, hobbies=["science"], skills=[["275]]}

UPDATE Here's the hash values when I debug the code:

更新这是调试代码时的哈希值：

 0 = {java.util.HashMap$HashMapEntry@4884} "hobbies" -> "{"1":"1"}"
 1 = {java.util.HashMap$HashMapEntry@4885} "password" -> "admin"
 2 = {java.util.HashMap$HashMapEntry@4886} "username" -> "admin"
 3 = {java.util.HashMap$HashMapEntry@4887} "skills" -> "{"1":{"Boxing":"Yes"}}"

I never succeed to communicate with the PHP Server API. Please help me where am I missing or wrong.

我从未成功与PHP Server API进行通信。请帮助我，我在哪里错过或错了。

there is a library how call GSON, search it on internet it's the fastest and simplest way to resolve String to Json and Json to String.

有一个库如何调用GSON，在互联网上搜索它是解析String到Json和Json到String的最快和最简单的方法。

I think your problem is that associative array in php represents JSON object in your json string so you probably should send something like this to your PHP Server API:

我认为你的问题是php中的关联数组代表你的json字符串中的JSON对象，所以你可能应该向你的PHP Server API发送这样的东西：

{
    "password": "admin",
    "username": "admin",
    "hobbies":{
        "1": "science"
    },
    "skills": {
        "1": {
            "Boxing": "Yes"
        }
    }
}

Here i can't be 100% sure and it depends on your server implementation, but to achieve the json output from above, your getParam() should look like this:

这里我不能100％肯定，这取决于你的服务器实现，但要实现上面的json输出，你的getParam（）应如下所示：

protected String getParams() {
    JSONObject jParams = new JSONObject();

    try {
        JSONObject arrHobbies = new JSONObject();
        arrHobbies.put("1", "science");


        JSONObject boxing = new JSONObject();
        boxing.put("Boxing", "Yes");

        JSONObject arrSkills = new JSONObject();
        arrSkills.put("1", boxing);


        jParams.put("username", "admin");
        jParams.put("password", "admin");

        jParams.put("hobbies", arrHobbies);
        jParams.put("skills", arrSkills);
    } catch (JSONException e) {
        e.printStackTrace();
    }

    return jParams.toString();
}

Hope this may help you :

希望这可以帮助你：

@Override protected Map getParams() {

@Override protected Map getParams（）{

    Map<String, String> jParams = new HashMap<String, String>();

    JSONArray arrHobbies = new JSONArray();
    JSONArray arrSkills1 = new JSONArray();
    JSONArray arrSkills2 = new JSONArray();

    arrHobbies.put("science");
    arrSkills1.put("Boxing");
    arrSkills1.put("Yes");

    arrSkills2.put(arrSkills1);


    jParams.put("username", "admin");
    jParams.put("password", "admin");
    jParams.put("hobbies", arrHobbies.toString());
    jParams.put("skills", arrSkills2.toString());

    return jParams;
}
