Question

好吧，我之前使用过POST，但我从来没有使用POST阵列。（真）

这是POST表单：

{

    "about": "about me",
    "sports": [
    {
            "id": 1,
            "level": 3

    },

    {

             "id": 2,
             "level": 4

    }

    ]

}

所以我必须发送一个带有“about”键和值的JSONObject，以及一个也可能为null的“sports”JSONArray。

我尝试了以下内容：

1

List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
    nameValuePair.add(new BasicNameValuePair("about", "Lorem ipsum about me"));
    nameValuePair.add(new BasicNameValuePair("sports", "[]"));

2

  List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>();
        nameValuePair.add(new BasicNameValuePair("about", "Lorem ipsum about me"));
        nameValuePair.add(new BasicNameValuePair("sports", new ArrayList<NameValuePair>()));
                                                  ///Of course its silly it doesnt work at all

所以我的问题是如何获得这个POST表单？

我的帖子：

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httppost.addHeader("Content-Type", "application/json");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse httpResponse = httpclient.execute(httppost);

Answer 1

这里我为您手动构建了JSONObject：

try{
    JSONObject attr1 = new JSONObject("{\"id\": 1, \"level\":3 }");
    JSONArray sports = new JSONArray();
    sports.put(attr1);
    //sports.put(attr2); and so on
    JSONObject yourObject = new JSONObject("{\"about\": \"About me\"}");
    yourObject.put("sports", sports);

    String url = yourObject.toString();
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(url);
    HttpResponse httpResponse = httpclient.execute(httppost);

}catch(Exception e){
}

正如您所看到的，我已经从字符串构建了json的一些部分，但是您也可以创建一个空对象并用数据填充它（就像我在jsonarray中所做的那样）
