Im trying to get all the xml data from a myanimelist request.
I've ried this code (see code below) on an other url and this worked.
Now, for myanimelist you need an account to request queries. I have tried different things like changing the location of uc.setRequestProperty ("Authorization", getBasicAuthenticationEncoding()); before and after the openConnection(); But nothing seems to work. The code below gives me this error: server returned HTTP response code: 401 for URL: http.
Can someone help me with this?
Code: (i used fake pwds for the example)
System.out.println(getXMLFromUrl("https://myanimelist.net/api/anime/search.xml?q=" + "2017"));
private String getBasicAuthenticationEncoding() {
String username= "username";
String password = "mypwd";
String userPassword = username + ":" + password;
#SuppressWarnings("static-access")
String basicAuth = "Basic " + new String(new Base64().encode(userPassword.getBytes()));
return basicAuth;
}
public String getXMLFromUrl(String url) throws IOException {
URL u = new URL(url);
URLConnection uc = u.openConnection();
uc.setRequestProperty ("Authorization", getBasicAuthenticationEncoding());
InputStream in = uc.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(uc.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
System.out.println(line);
sb.append(line + "\n");
}
br.close();
return sb.toString();
}

I am struggling to understand the whole new idea of accessing my organizatioon's Sharepoint content using Sahrepoint REST API and I am trying to implementing it in java. My aim is to read all the files in "abc" folder which is in Documents folder. Steps I did.
Register the app:
Click Generate Client ID,
Click Generate Client Secret,
Gave Title,
Gave Appdomain as companyname.onmicrosoft, and
Gave Request URI as https://companyname.sharepoint.com/Shared%20Documents/Forms/AllItems.aspx
Got the app registered. I have client id, client secret, and tenant id.
I used the below code to generate the access token
public String getSpToken(String shp_clientId, String shp_tenantId, String shp_clientSecret) {
String accessToken = "";
try {
// AccessToken url
String wsURL = "https://accounts.accesscontrol.windows.net/" + shp_tenantId + "/tokens/OAuth/2";
URL url = new URL(wsURL);
URLConnection connection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection) connection;
// Set header
httpConn.setRequestProperty("Content-Type", " ");
httpConn.setDoOutput(true);
httpConn.setDoInput(true);
httpConn.setRequestMethod("POST");
// Prepare RequestData
String jsonParam = "grant_type=client_credentials"
+ "&client_id=" + shp_clientId + "#" + shp_tenantId
+ "&client_secret=" + shp_clientSecret
+ "&resource=00000003-0000-0ff1-ce00-000000000000/www.companyname.sharepoint.com#" + shp_tenantId;
// Send Request
DataOutputStream wr = new DataOutputStream(httpConn.getOutputStream());
wr.writeBytes(jsonParam);
wr.flush();
wr.close();
// Read the response.
InputStreamReader isr = null;
if (httpConn.getResponseCode() == 200) {
isr = new InputStreamReader(httpConn.getInputStream());
} else {
isr = new InputStreamReader(httpConn.getErrorStream());
}
BufferedReader in = new BufferedReader(isr);
String responseString = "";
String outputString = "";
// Write response to a String.
while ((responseString = in.readLine()) != null) {
outputString = outputString + responseString;
}
//Printing the response to the console
System.out.println("Output from the REST" + outputString);
// Extracting accessToken from string, here response (outputString)is a Json format string
if (outputString.indexOf("access_token\":\"") > -1) {
int i1 = outputString.indexOf("access_token\":\"");
String str1 = outputString.substring(i1 + 15);
int i2 = str1.indexOf("\"}");
String str2 = str1.substring(0, i2);
accessToken = str2;
}
//Printing the access token
System.out.println("Access token is " + accessToken);
} catch (Exception e) {
accessToken = "Error: " + e.getMessage();
}
return accessToken;
}
Now that I have the access token in the String variable "accessToken", I used the following code to read the filenames inside the folder "abc" in Documents folder using readFiles() method
public void readFiles(String accessToken) {
try {
//Frame SharePoint siteURL
String siteURL = "https://companyname.sharepoint.com";
//Frame SharePoint URL to retrieve the name of all of the files in a folder
String wsUrl = siteURL + "/_api/web/GetFolderByServerRelativeUrl('Shared%20Documents/abc')/Files";
//Create HttpURLConnection
URL url = new URL(wsUrl);
URLConnection connection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection) connection;
//Set Header
httpConn.setRequestMethod("GET");
httpConn.setRequestProperty("Authorization", "Bearer " + accessToken);
httpConn.setRequestProperty("accept", "application/json;odata=verbose"); //To get response in JSON
//httpConn.setRequestProperty("AllowAppOnlyPolicy", "true");
//httpConn.setRequestProperty("Scope", "http://sharepoint/content/sitecollection/web\" Right=\"FullControl");
//Read the response
String httpResponseStr = "";
InputStreamReader isr = null;
System.out.println(httpConn.getResponseCode());
if (httpConn.getResponseCode() == 200) {
isr = new InputStreamReader(httpConn.getInputStream());
} else {
isr = new InputStreamReader(httpConn.getErrorStream());
}
BufferedReader in = new BufferedReader(isr);
String strLine = "";
while ((strLine = in.readLine()) != null) {
httpResponseStr = httpResponseStr + strLine;
}
//Print response
System.out.println(httpResponseStr);
} catch (Exception e) {
System.out.println("Error while reading file: " + e.getMessage());
}
}
}
When I execute the above code I am getting {"error_description":"Exception of type 'Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException' was thrown."}. Could someone please help me to figure out what I am doing wrong? I have been sitting on this for days and not able to resolve it.
Please help!
I am trying to get coordinates from a location entered from the user using HTTP request to Geocode API.
The address string I pass into the method is formatted with "%" in between the spaces so that it can be put into a URL.
Sometimes, it will return a null value and I have no idea why.
It works sometimes so I think there isn't a problem with the JSON array get lines.
public CheckLocation(String address) {
try {
String key = "insert key";
String url = "https://maps.googleapis.com/maps/api/geocode/json?address=" + address + "?key=" + key;
// String key = "test/";
URL urlObj = new URL(url);
HttpURLConnection con = (HttpURLConnection) urlObj.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();
// Read JSON response and print
JSONObject myResponse = new JSONObject(response.toString());
double laditude = ((JSONArray)myResponse.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lat");
double longitude = ((JSONArray)myResponse.get("results")).getJSONObject(0)
.getJSONObject("geometry").getJSONObject("location")
.getDouble("lng");
formattedAddress = ((JSONArray)myResponse.get("results")).getJSONObject(0)
.getString("formatted_address");
coordinates = (laditude + "," + longitude);
}
catch (Exception e) {
e.printStackTrace();
}
}
What about encoding parameters values? encode both address and key:
String url = "https://maps.googleapis.com/maps/api/geocode/json?address=" +
URLEncoder.encode(address, "UTF-8"); + "?key=" + URLEncoder.encode(key, "UTF-8");
URLEncoder should be the way to go. You only need to keep in mind to encode only the individual query string parameter name and/or value
hi all I'm trying to send a request to Wit to a simple wit application that i've created and I'm doing this in java. I'm trying to print the wit response into the console but the only thing that prints is the following line:
class sun.net.www.protocol.http.HttpURLConnection$HttpInputStream
The code that I am using to send the request is a code that I have found on this forum, I repost it for be more specific:
public static String getCommand(String command) throws Exception {
String url = "https://api.wit.ai/message";
String key = "MY_SERVER_KEY";
String param1 = "my_param";
String param2 = command;
String charset = "UTF-8";
String query = String.format("v=%s&q=%s",
URLEncoder.encode(param1, charset),
URLEncoder.encode(param2, charset));
URLConnection connection = new URL(url + "?" + query).openConnection();
connection.setRequestProperty ("Authorization", "Bearer " + key);
connection.setRequestProperty("Accept-Charset", charset);
InputStream response = connection.getInputStream();
return response.toString();
}
how can i return the wit response?
EDIT:
I'm trying with apache as you suggested to me, but it keeps to send me error 400.
Here the code:
public static void getCommand2(String command) throws Exception {
String query = URLEncoder.encode(command, "UTF-8");
String key = "my_key";
String url = "https://api.wit.ai/message?v="+my_code+"q"+query;
HttpClient client = HttpClientBuilder.create().build();
HttpGet request = new HttpGet(url);
// add request header
request.addHeader("Authorization: Bearer", key);
HttpResponse response = client.execute(request);
System.out.println("Response Code : "
+ response.getStatusLine().getStatusCode());
BufferedReader rd = new BufferedReader(
new InputStreamReader(response.getEntity().getContent()));
StringBuffer result = new StringBuffer();
String line = "";
while ((line = rd.readLine()) != null) {
result.append(line);
}
}
You don't have to use Apache
Taken from the Wit.ai android-sdk.
public static String convertStreamToString(InputStream is) throws IOException
{
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line;
while ((line = reader.readLine()) != null)
{
sb.append(line);
}
is.close();
return sb.toString();
}
The problem you were having is that the InputStream's toString method is only returning it's class name. Another thing you can try is using HTTPURLConnection rather than just the simple URLConnection, since you know it will be an HTTP request as opposed to another protocol.
I want to integrate login with gmail as well as login with facebook on our website, so that without a new signup user can create his/her account on our website. Its a gwt with java based website. I have tried some codes and getting error java.io.IOException: Server returned HTTP response code: 401 for URL: https://accounts.google.com/o/oauth2/token and I am totally unaware why i am getting this error.
I have used thisdoc for code. Any help in why actually I am getting this error. have i missed something? any help in it.
Obviously it's Unauthorized(401)..You must have to give client_id and client_secret and also each request to the Gmail API requires an access token.
try this code at your redirected method
String code = request.getParameter("code");
String urlParameters = "code=" + code + "&client_id="
+ CLIENT_ID + "&client_secret="
+ CLIENT_SECRET + "&redirect_uri="
+ REDIRECT_GMAIL_URI
+ "&grant_type=authorization_code";
URL url = new URL("https://accounts.google.com/o/oauth2/token");
URLConnection urlConn = url.openConnection();
urlConn.setDoOutput(true);
OutputStreamWriter writer = new OutputStreamWriter(
urlConn.getOutputStream());
writer.write(urlParameters);
writer.flush();
String line, outputString = "";
BufferedReader reader = new BufferedReader(new InputStreamReader(
urlConn.getInputStream()));
while ((line = reader.readLine()) != null) {
outputString += line;
}
JsonObject json = (JsonObject) new JsonParser().parse(outputString);
String access_token = json.get("access_token").getAsString();
url = new URL(
"https://www.googleapis.com/oauth2/v1/userinfo?access_token="
+ access_token);
urlConn = url.openConnection();
outputString = "";
reader = new BufferedReader(new InputStreamReader(
urlConn.getInputStream()));
while ((line = reader.readLine()) != null) {
outputString += line;
}
System.out.println(outputString);

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);
