[英]Get request with Json response?
我有以下從json響應返回特殊字段的類。 在此請求的方法是post。 我該如何使用get方法呢? 我也想用標頭發出get請求
CloseableHttpClient httpClient = HttpClients.createDefault();
HttpPost post = new HttpPost(
"");
post.addHeader("Auth-Token", authenticationValues.getAuthToken());
post.addHeader("device-id", authenticationValues.getDeviceId());
List<NameValuePair> params = new ArrayList<>();
params.add(new BasicNameValuePair("task", "savemodel"));
String generatedJSONString = null;
params.add(new BasicNameValuePair("code", generatedJSONString));
CloseableHttpResponse response = null;
Scanner in = null;
try {
post.setEntity(new UrlEncodedFormEntity(params));
response = httpClient.execute(post);
HttpEntity entity = response.getEntity();
in = new Scanner(entity.getContent());
while (in.hasNext()) {
JsonString += in.next();
}
EntityUtils.consume(entity);
} catch (IOException e) {
e.printStackTrace();
}
// System.out.println(JsonString);
JSONObject jsonObject = new JSONObject(JsonString);
JSONObject myResponse = jsonObject.getJSONObject("login");
Object myResponse2 = myResponse.get("loginStatus");
System.out.println(myResponse2);
嘗試這個...
URL url = new URL("http://"...);
HttpURLConnection http = (HttpURLConnection)
url.openConnection();
http.setRequestMethod("GET");
http.setDoOutput(true);
http.connect();
OutputStream out = http.getOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(out);
writer.write(FOO);
writer.flush();
writer.close();
InputStreamReader in = new InputStreamReader(http.getInputStream());
BufferedReader br = new BufferedReader(in);
char[] chars = new char[BUF_SIZE];
int size = br.read(chars);
String response = new String(chars).substring(0, size);
全部包含在try-catch塊中。
