I am looking to use the following curl request in a java code. I see that we can use httpget to call rest services.
Here is my curl command:
curl -XGET 'localhost:9200/indexname/status/_search' -d '{"_source": {"include": [ "field1", "name1" ]}, "query" : {"term": { "Date" :"2000-12-23T10:12:05" }}}'
How can I put that command in my HttpGet httpGetRequest = new HttpGet(....);
Please advice. Thanks.
You could use the HttpURLConnection.
This code is an example I think it will work for you:
public void get() throws IOException{
//Create a URL object.
String url = "localhost:9200/indexname/status/_search";
URL getURL = new URL(url);
//Establish a https connection with that URL.
HttpsURLConnection con = (HttpsURLConnection) getURL.openConnection();
//Select the request method, in this case GET.
con.setRequestMethod("GET");
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
String parameters = "{\"_source\": {\"include\": [ \"field1\", \"name1\" ]}, \"query\" : {\"term\": { \"Date\" :\"2000-12-23T10:12:05\" }}}";
//Write the parameter into the Output Stream, flush the data and then close the stream.
wr.writeBytes(parameters);
wr.flush();
wr.close();
System.out.println("\nSending 'GET' request to URL : " + url);
int responseCode;
try {
responseCode = con.getResponseCode();
System.out.println("Response Code : " + responseCode);
} catch (Exception e) {
System.out.println("Error: Connection problem.");
}
//Read the POST response.
InputStreamReader isr = new InputStreamReader(con.getInputStream());
BufferedReader br = new BufferedReader(isr);
StringBuffer response = new StringBuffer();
String inputLine;
while ((inputLine = br.readLine()) != null) {
//Save a line of the response.
response.append(inputLine + '\n');
}
br.close();
System.out.println(response.toString());
}
If that doesnt work it's because i must have misstyped the parameters, try it anyway
The combination -X GET and -d results in your data being appended to the URL in application/x-www-form-urlencoded format.
Therefore, I suggest using URLEncoder as follows:
String host = "localhost:9200/indexname/status/_search";
String data = "{\"_source\": {\"include\": [ \"field1\", \"name1\" ]}, \"query\" : {\"term\": { \"Date\" :\"2000-12-23T10:12:05\" }}}";
String url = host + "?" + URLEncoder.encode(data, "UTF-8");

I am trying to read JSON data with Java, I was successfully to read the first array, below is my JSON report from url.
{
"success":1,
"object":"sale",
"id":"sl987575",
"created":"2019-08-03 21:40:35",
"product_id":"prd00123",
"product_name":"AirBuss",
"amount":"100.00",
"currency":"USD",
"status":"Completed",
"meta":[],
"customer":{
"object":"customer",
"id":"001234",
"email":"someone#email.com",
"name":"Full Name",
"country":null,
"firstname":"Full",
"lastname":"Name"}}
I can read "product_name" and "status" but cannot read the "email" data.
public static void call_me() throws Exception {
String url = "Link WEbsite/api/?apiKey=23459876";
URL obj = new URL(url);
HttpURLConnection con = (HttpURLConnection) obj.openConnection();
// optional default is GET
con.setRequestMethod("GET");
//add request header
con.setRequestProperty("User-Agent", "Mozilla/5.0");
int responseCode = con.getResponseCode();
System.out.println("\nSending 'GET' request to URL : " + url);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print in String
System.out.println(response.toString());
//Read JSON response and print
JSONObject myResponse = new JSONObject(response.toString());
System.out.println("result after Reading JSON Response");
System.out.println("Product Name : "+myResponse.getString("product_id"));
System.out.println("status : "+myResponse.getString("status"));
System.out.println("Email : "+myResponse.getString("email"));
}
Try this:
System.out.println("Email : " + myResponse.getJSONObject("customer").getString("email"));
Because 'email', 'country' etc. fields in a nested object named customer.
I just found solution for my own question..
JSONObject customer_data = myResponse.getJSONObject("customer");
System.out.println("Email : "+customer_data.getString("email"));
I am tiring to execute some of my project URLs through JAVA APIs. But some of them contain JSON values. Its not accepting the JSON I am providing.
If I hit same URL through browser it executes. I am not getting what is going wrong. Are the " " specified not accepted ?
URL = http://admin.biin.net:8289/project.do?cmd=AddProject&mode=default&projectFieldValueJSON={"fieldIds":[{"id":1360,"value":"project SS33"},{"id":1362,"value":"12/03/2015"},{"id":1363,"value":"12/31/2015"}],"state":1}&jsessionid=AE5B03C9791D1019DCD7BBF0E34CCFEE
The Code is as follows
String requestString = "http://admin.biin.net:8289 /project.do?cmd=AddProject&mode=default&projectJSON={"fieldIds":[{"id":1360,"value":"project SS33"},{"id":1362,"value":"12/03/2015"},{"id":1363,"value":"12/31/2015"}],"state":1}&jsessionid=AE5B03C9791D1019DCD7BBF0E34CCFEE"
URL url = new URL(requestString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.connect();
InputStream in = conn.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));
StringBuffer responseString = new StringBuffer();
String line = null;
while ((line = reader.readLine()) != null) {
responseString.append(line);
}
Error :
java.io.IOException: Server returned HTTP response code: 505 for URL: http://admin.biin.net:8289/project.do?cmd=AddProject&mode=default&projectJSON={"fieldIds":[{"id":1360,"value":"project SS33"},{"id":1362,"value":"12/03/2015"},{"id":1363,"value":"12/31/2015"}],"state":1}&jsessionid=AE5B03C9791D1019DCD7BBF0E34CCFEE
If I remove the JSON the URL executes.
Don't pass json in QueryString. Since you are using HTTP POST. You should send the sensitive data in the HTTP body. Like this
String str = "some string goes here";
byte[] outputInBytes = str.getBytes("UTF-8");
OutputStream os = conn.getOutputStream();
os.write( outputInBytes );
os.close();
For your current problem. Encode the json value before passing it in url.
Try this:
try {
String s = "http://admin.biin.net:8289/project.do?cmd=AddProject&mode=default&projectFieldValueJSON="
+ URLEncoder.encode("{\"fieldIds\":[{\"id\":1360,\"value\":\"project SS33\"},{\"id\":1362,\"value\":\"12/03/2015\"},{\"id\":1363,\"value\":\"12/31/2015\"}],\"state\":1}", "UTF-8")
+ "&jsessionid=AE5B03C9791D1019DCD7BBF0E34CCFEE";
System.out.println(s);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
Result: http://admin.biin.net:8289/project.do?cmd=AddProject&mode=default&projectFieldValueJSON=%7B%22fieldIds%22%3A%5B%7B%22id%22%3A1360%2C%22value%22%3A%22project+SS33%22%7D%2C%7B%22id%22%3A1362%2C%22value%22%3A%2212%2F03%2F2015%22%7D%2C%7B%22id%22%3A1363%2C%22value%22%3A%2212%2F31%2F2015%22%7D%5D%2C%22state%22%3A1%7D&jsessionid=AE5B03C9791D1019DCD7BBF0E34CCFEE
I'm trying to send email using the SES HTTPS Query API. I have a java method that sends a GET request to an Amazon SES endpoint, I'm trying to send an email with SES and capture the result.

I have calculated the signature correctly, because on hitting from postman client getting 200 response.
URL url = new URL("https://email.us-east-1.amazonaws.com?"+data);
You missed a '/' before the question mark. It should be
URL url = new URL("https://email.us-east-1.amazonaws.com/?"+data);
I have a cURL command I want to translate in Java
curl -H "Key: XXX" -d url=http://www.google.com http://myapi.com/v2/extraction?format=json
It works fine.
I started to do in Java: (CODE EDITED, it works)
try {
// POST
System.out.println("POSTING");
URL url = new URL("http://myapi.com/v2/extraction?format=json");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Key", "XXX");
String data = "http://www.google.com";
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
writer.write("url=" +data);
writer.close();
int responseCode = connection.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + data);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
System.out.println("REPOSNE" +response.toString());
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
// OK
} else {
// Server returned HTTP error code.
}
} catch (MalformedURLException e) {
// ...
} catch (IOException e) {
// ...
}
But I don't know how to set my arguments.
Thanks for your help.

If you mean to set a header field Key with value XXX you can use the setRequestProperty
ie
conn.setRequestProperty("Key", "XXX");
If you want to send data, use
String data = "url=http://www.google.com";
conn.setRequestProperty("Content-Length", "" + Integer.toString(data.getBytes().length));
EDIT:-
For posting data as form url encoded, try the following code
String data = "url=" + URLEncoder.encode("http://www.google.com", "UTF-8");
conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
wr.write(data.getBytes());
update : this is a duplicate,
i'm building a Proxy-custom-tag with grails taglib, per default it makes a get-request, now i'm facing the problem, that it should be able to handle Post-requests too,#
and i'm able to check the request-method and conditionally set the openConnection method to post if necessary, but i dont know how to append the post-params to the request.
here 's my code so far
def wordpressContent = { attrs, body ->
def url
def requestMethod = request.getMethod()
def queryString = request.getQueryString()?'&'+request.getQueryString():''
def content
println "method :"+requestMethod
println "params == "+params // <- inside here are the post-parameters
url = grailsApplication.config.wordpress.server.url+attrs.pageName+'?include=true'+queryString
try {
content = url.toURL().openConnection().with { conn ->
if(requestMethod == 'POST'){
println "Its a POST"
conn.setRequestMethod("POST")
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
// HOW to append the params here ?
}
readTimeout = 6000
if( responseCode != 200 ) {
throw new Exception( 'Not Ok' )
}
conn.content.withReader { r ->
r.text
}
}
}
catch( e ) {
println "exception : "+e
content="<div class='float' style='margin-top:10px;width:850px;background-color:white;border-radius:5px;padding:50px;'>Hier wird gerade gebaut</div>"
}
out << content
}
im very stuck here right now, i found answers saying to use this syntax
Writer wr = new OutputStreamWriter(conn.outputStream)
wr.write(postParams)
wr.flush()
wr.close()
but i dont know how to include that to my existing code,
for any hints thanks in advance
update: my solution was to build up the post-parameter-querystring by iterating over the params object in this pattern "xyz=zyx&abc=cba" and write it to the outputStream like above
// HTTP POST request
private void sendPost() throws Exception {
String url = "https://selfsolve.apple.com/wcResults.do";
URL obj = new URL(url);
HttpsURLConnection con = (HttpsURLConnection) obj.openConnection();
//add request header
con.setRequestMethod("POST");
con.setRequestProperty("User-Agent", USER_AGENT);
con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
String urlParameters = "sn=C02G8416DRJM&cn=&locale=&caller=&num=12345";
// Send post request
con.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(con.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
int responseCode = con.getResponseCode();
System.out.println("\nSending 'POST' request to URL : " + url);
System.out.println("Post parameters : " + urlParameters);
System.out.println("Response Code : " + responseCode);
BufferedReader in = new BufferedReader(
new InputStreamReader(con.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString());
}
you are using grails so you can also use groovy HTTPBuilder like below
