java - http POST 格式问题 - 作为数组、列表？

Question

我正在尝试发出“空闲/忙碌”请求以连接到 Google Calendar API。目前我被困在格式化 http POST 上。我收到错误:

{
  "error": {
   "errors": [
    {
     "domain": "global",
     "reason": "parseError",
     "message": "Parse Error"
    }
   ],
   "code": 400,
   "message": "Parse Error"
  }
}

<小时/>

我正在尝试像这样格式化请求:

{
  "timeMin": datetime,
  "timeMax": datetime,
  "timeZone": string,
  "groupExpansionMax": integer,
  "calendarExpansionMax": integer,
  "items": [
    {
      "id": string
    }
  ]
}

目前正在执行此操作来格式化它:

String[] stringPairs = new String[]{
            "timeMin",       date1,
            "timeMax",       date2,
            "items[]",       calendarID,
            "timezone",      "Canada/Toronto"};

//Create an HTTP post request
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("HostULR");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(stringPairs.length/2 - 1);

for (int i = 0; i < stringPairs.length; i += 2) {
    nameValuePairs.add(new BasicNameValuePair(stringPairs[i], stringPairs[i+1]));
}

post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
org.apache.http.HttpResponse response = client.execute(post);
HttpEntity entity = response.getEntity();

我相信我搞砸的部分是“items”部分。任何帮助将不胜感激。

不知道这对于 java 是否正确，但在 C 中，你只需将另一个 json 插入其中即可生成复杂的 json。

也许这个网站可以帮助你。

编辑:我注意到表单是一个对象数组...所以正确的实现是这样的。

  JSONObject obj=new JSONObject();
  obj.put("ID", string);

  JSONArray list = new JSONArray();

  list.add(obj);

  JSONObject jsonObj = new JSONObject();{
            object.put("timeMin", date1)
            ....

另外，我不知道这段代码...

"timezone",      "Canada/Toronto"}, accessToken );

对于 json 对象，通常用 {} 表示 json 对象 [] 这些是数组。

编辑2:创建 JSON 后执行此操作

StringEntity entity = new StringEntity(json.toString());
                     entity.setContentType("application/json;charset=UTF-8");
                     entity.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json;charset=UTF-8"));
                     request.setHeader("Accept", "application/json");
                     request.setEntity(entity); 

                     HttpResponse response =null;
                     DefaultHttpClient httpClient = new DefaultHttpClient();

                     HttpConnectionParams.setSoTimeout(httpClient.getParams(), Constants.ANDROID_CONNECTION_TIMEOUT*1000); 
                     HttpConnectionParams.setConnectionTimeout(httpClient.getParams(),Constants.ANDROID_CONNECTION_TIMEOUT*1000); 
                     try{

                     response = httpClient.execute(request); 
                     }
                     catch(SocketException se)
                     {
                         Log.e("SocketException", se+"");
                         throw se;
                     }




InputStream in = response.getEntity().getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
String line = null;
while((line = reader.readLine()) != null){
    sb.append(line);
