如何使用HttpUrl连接在android api 23中使用post发送名称-值对对象或内容-值对象？

//这是我试过的。 //我不知道如何附加inputurl和内容值，并使用HttpURLConnection将其发送到服务器

公共JSONObject getJsonFromUrl（字符串inputurl，ContentValues）{

///请在此处插入代码，以便在url中附加值。 connection.connect（）

---

}

如果您想通过HttpUrlConnection实例将JSON对象发布到url，您可以编写如下示例

    DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());
    wr.writeBytes(jsonObject.toString());
    wr.flush();
    wr.close();
Where,

jsonObject is the json object which you would be posting to the URL 

整个代码可能如下所示

URL url = new URL("this would be your url where you want to POST");

HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setDoOutput(true);
// when you are posting do make sure you assign appropriate header
// In this case POST.

httpURLConnection.setRequestMethod("POST");
httpURLConnection.connect();

// like this you can create your JOSN object which you want to send
JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("email", "dddd@gmail.com");
jsonObject.addProperty("password", "password");

// And this is how you will write to the URL
DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());
wr.writeBytes(jsonObject.toString());
wr.flush();
wr.close();

Log.d("TAG", "" + IOUtils.toString(httpURLConnection.getInputStream()));

可能的重复可能的重复

    DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());
    wr.writeBytes(jsonObject.toString());
    wr.flush();
    wr.close();
Where,

jsonObject is the json object which you would be posting to the URL 

URL url = new URL("this would be your url where you want to POST");

HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
httpURLConnection.setDoOutput(true);
// when you are posting do make sure you assign appropriate header
// In this case POST.

httpURLConnection.setRequestMethod("POST");
httpURLConnection.connect();

// like this you can create your JOSN object which you want to send
JsonObject jsonObject = new JsonObject();
jsonObject.addProperty("email", "dddd@gmail.com");
jsonObject.addProperty("password", "password");

// And this is how you will write to the URL
DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());
wr.writeBytes(jsonObject.toString());
wr.flush();
wr.close();

Log.d("TAG", "" + IOUtils.toString(httpURLConnection.getInputStream()));
