Can’t convert String into json, and it seems that it will be superfluous for the entire string.
Was thinking maybe json might have helped me out here, but it doesn't seem to give me what I want or I don't know how it will be work.
How I can check the string?
I need to check:
METHOD: GET and URL: http://google.com/
also to check the BODY contains the fields userId, replId and view (no values, only keys)
I was trying to find a way to check that:
if (msg.contains("METHOD: GET") && msg.contains("URL: http://google.com/") && msg.contains("BODY: etc...")) {
System.out.println("ok");
}
It doesn't work. Some values from BODY that are dynamic and that's why for BODY the check won't pass if it’s so hardcoded String. And I guess there're any better ways to do that.
I'd like to have something like:
Assert.assertEquals(
msg,
the expected value for METHOD, which contains GET); // same here for URL: http://google.com/
Assert.assertEquals(
msg,
the expected value for BODY that has userId, replId, and view fields); // or make this assertion for each field separately, such as there is an assertion for the userId field, the same assertions for replId and view
And here's the String:
String msg = "METHOD: GET\n" +
"URL: http://google.com/\n" +
"token: 32Asdd1QQdsdsg$ff\n" +
"code: 200\n" +
"stand: test\n" +
"BODY: {\"userId\":\"11022:7\",\"bdaId\":\"110220\",\"replId\":\"fffDss0400rDF\",\"local\":\"not\",\"ttpm\":\"000\",\"view\":true}";
I can't think of any way to check that. Any ideas?
You can use the java.util.List Interface (of type String) and place the string contents into that list. Then you can use the List#contains() method, for example:
String msg = "METHOD: GET\n" +
"URL: http://google.com/\n" +
"token: 32Asdd1QQdsdsg$ff\n" +
"code: 200\n" +
"stand: test\n" +
"BODY: {\"userId\":\"11022:7\",\"bdaId\":\"110220\",\"replId\":\"fffDss0400rDF\",\"local\":\"not\",\"ttpm\":\"000\",\"view\":true}";
// Split contents of msg into list.
java.util.List<String> list = Arrays.asList(msg.split("\n"));
if (list.contains("METHOD: GET")) {
System.out.println("YUP! Got: --> 'METHOD: GET'");
}
else {
System.out.println("NOPE! Don't have: --> 'METHOD: GET'");
}
I've tried to use Assert:
String[] arr1 = msg.split("\n");
Map<String, String> allFieldsMessage = new HashMap<>();
for (String s : arr1) {
String key = s.trim().split(": ")[0];
String value = s.trim().split(": ")[1];
allFieldsMessage.put(key, value);
}
Assert.assertEquals(
allFieldsMessage.get("METHOD"),
"GET"
);
And the same for URL. But my problem is in BODY part. I thought maybe try to parse this particular part of String into json and then only check the necessary keys.

NullPointerException at if (hrefAttr.contains("?"))
I'm running into a problem. I'm using selenium and JUnit to parse through links and compare them to a list of links provided from a CSV file.
Everything was going well until I realized that I have to test the URLs and the query strings separately. I attempted to create an if statement saying that if the href attribute contained a "?" split the entire URL into an array containing two strings. The URL destination being the first string indexed and the query string being the second string indexed. and return the URL destination and append it to an ID. If there was no "?" in the URL string, just return the URL string and append it to an ID
I think the logic looks accurate but I keep returning a Null Pointer Exception at Line 76 (where the href.contains("?") condition is located. Code below:
public static ArrayList<String> getURLSFromHTML(WebDriver driver) {
// prepares variable for array of html link URLs
ArrayList <String> pageLinksList = new ArrayList<String>();
// prepares array to place all of the <a></a> tags found in the HTML
List <WebElement> aElements = driver.findElements(By.tagName("a"));
// loops through all the <a></a> tags found in the HTML
for (WebElement aElement : aElements) {
/*
* grabs the href attribute value and stores it into a variable
* grabs the QA_ID attribute value and stores it in a variable
* concatenates the QA_ID value with the href value and stores them in a variable
*/
String hrefAttr = aElement.getAttribute("href");
String QA_ID = aElement.getAttribute("QA_ID");
String linkConcat;
if (hrefAttr.contains("?")) {
String[] splitHref = hrefAttr.split("\\?");
String URL = splitHref[0];
linkConcat = QA_ID + "_" + URL;
} else {
linkConcat = QA_ID + "_" + hrefAttr;
}
String urlIgnoreAttr = aElement.getAttribute("URL_ignore");
String combIgnore = QA_ID + "_" + urlIgnoreAttr;
String combIgnoreVal = "ignore";
/*
* if the QA_ID is not null then add value to pageLinksList
* if URL_ignore attribute="ignore" in html, then add combIgnore value to pageLinksList
* else add linkConcat to pageLinksList
*/
if(!Objects.isNull(QA_ID)) {
if (Objects.equals(urlIgnoreAttr, combIgnoreVal)) {
pageLinksList.add(combIgnore);
}else {
pageLinksList.add(linkConcat);
}
}
}
System.out.println(pageLinksList);
return pageLinksList;
}
Please help!
The obvious solution is to check for null:
if (hrefAttr != null && hrefAttr.contains("?")) {
String[] splitHref = hrefAttr.split("\\?");
String URL = splitHref[0];
linkConcat = QA_ID + "_" + URL;
} else {
linkConcat = QA_ID + "_" + hrefAttr;
}
An anchor tag without href attribute can still be valid. Without html source we cannot explain the reason for the missing href attributes. The else branch will not throw a NPE, but it my be useless with hrefAttr == null.
I have some data extracted from a MySQL database where some fields are NULL. Not accidentally as a string but properly stored as NULL. When I send these null-data JSON-encoded to my android app, they end up being a string "null" of length 4. So I rebuilt this problem condensed to the essential code:
PHP:
$string = null;
echo $array[0]['alt_names'] = $string;
echo json_encode($array);
Java: (My PHP class returns a string, in this case jsonResult)
Log.i("Tag", "result = " + jsonResult); // result = [{"alt_names":null}]
JSONArray jsonArray = new JSONArray(jsonResult);
Log.i("Tag", "jsonArray = " + jsonArray); // jsonArray = [{"alt_names":null}]
JSONObject jsonObject = new JSONObject(jsonArray.getJSONObject(0).toString());
Log.i("Tag", "jsonobject = " + jsonObject); // jsonobject = {"alt_names":null}
String test = jsonObject.get("alt_names").toString();
Log.i("Tag", "test: " + test); // test: null
Log.i("Tag", "test.length(): " + test.length()); // test.length(): 4
The missing quotation marks (not) enclosing null in the Log-output show me, that this is not a string "null" butt actually null. Nevertheless the string's length is 4 and this is true:
if (test.equals("null")) {Log.i("Tag", "true");} // true
What do I not understand? Thanks in advance!
Don't do a toString() on the object return by jsonObject.get("alt_names"). It is actually the static instance of JSONObject.NULL
Object test = jsonObject.get("alt_names");
System.out.println(test == JSONObject.NULL); // true
System.out.println(test.equals(null)); // true
System.out.println(jsonObject.isNull("alt_names")); // true
From javadoc :
It is sometimes more convenient and less ambiguous to have a NULL object than to use Java's null value. JSONObject.NULL.equals(null) returns true. JSONObject.NULL.toString() returns "null".
I have some issue with the code below, req.getHeader() is returning NULL
// The code below returns the expected value
String header = req.getHeader("x-key");
String size = req.getHeader("x-size");
String contentType = req.getContentType();
logger.info("Content-Length: " + req.getContentLength());
logger.info("x-key : " + header);
logger.info("x-size : " + size);
// The value of req.getHeader below is returning NULL
for (Enumeration e = req.getHeaderNames(); e.hasMoreElements();) {
String headerName = (String) e.nextElement();
logger.info("Name = " + headerName + " " + "Value = " + req.getHeader(headerName ));
}
What could be the problem?
Your code looks OK. If getHeader() returns null the header is indeed null, i.e. was not sent by client.
So, first check your client and be sure it sends the header. Second, try to use network sniffer, e.g. Wireshark and record the network activity.
If you need more assistance please post your client's code.
The below is part of the extract from the api docs.
public java.util.Enumeration getHeaderNames()
Some servlet containers do not allow servlets to access headers using this method, in which case this method returns null
I have a project as follows: Several photos are taken from a mobile, the photos are saved in a web system, which in turn displays the photos on google earth that is inside it. I've read many articles but all of them were using fetchKml, one good article that i've read was using php, but using fetchKml. I dont know if its possible using parseKml instead. Anyway, I'm not sure how to do this with the kml, so it looks tike this:
My Class KMLGenerator()
public static String getKMLFromObra (List<Obra> obraFotos) {
StringBuffer sb = new StringBuffer();
sb.append("<?xml version='1.0' encoding='UTF-8'?>");
sb.append("<kml xmlns='http://www.opengis.net/kml/2.2' " +
"xmlns:gx='http://www.google.com/kml/ext/2.2' " +
"xmlns:kml='http://www.opengis.net/kml/2.2' " +
"xmlns:atom='http://www.w3.org/2005/Atom'> ");
if (obraFotos != null && obraFotos.size() > 0) {
for (Obra o : obraFotos) {
for (Local local : o.getLocais()) {
sb.append("<Document>");
sb.append("<name>" + local.getName() + "</name>");
sb.append("<Style id='defaultStyles'>");
sb.append("<IconStyle>");
sb.append("<scale>1.1</scale>");
sb.append("<Icon>");
sb.append("<href>" + "http://localhost:8080/ConstruMobilFoto/lib/img/fotoIcon.png" + "</href>");
sb.append("</Icon>");
sb.append("</IconStyle>");
sb.append("</Style>");
sb.append("<Placemark>");
sb.append("<name>" + "Foto" + "</name>");
sb.append("<styleUrl>" + "#defaultStyles"+ "</styleUrl>");
sb.append("<altitudeMode>" + "relativeToGround" + "</altitudeMode>");
sb.append("<Point>");
sb.append("<altitudeMode>relativeToGround</altitudeMode>");
sb.append("<coordinates>" + local.getLongitude() + "," + local.getLatitude() + "," + 50</coordinates>");
sb.append("</Point>");
sb.append("<Link>");
sb.append("<href>" + local.getFotos() + "</href>");
sb.append("</Link>");
sb.append("</Placemark>");
sb.append("</Document>");
sb.append("</kml>");
return sb.toString();
}
}
}
return null;
}
I have a dwr function in my jsp that invokes this method, got its String results and make the parse like this:
Class PainelEarth()
#SuppressWarnings("static-access")
public String geraFotosObra (int idObra) throws Exception {
try {
List<Obra> obraFotos = obraBusiness.getObraLatLong(new Obra(idObra));
return new KMLGenerator().getKMLFromObra(obraFotos);
} catch (Exception e) {
log.error(e.getLocalizedMessage(), e);
return null;
}
}
and in my jsp page
function initCB(instance) {
// other codes
showPics(ge);
}
function showPics(ge) {
PainelEarthAjax.geraFotosObra({
callback : function(kmlString) {
var kmlObject = ge.parseKml(kmlString);
ge.getFeatures().appendChild(kmlObject);
}
});
return null;
}
Any help will be welcome!!
In your code if you look at the signature of the method geraFotosObra you can see it takes a single int parameter idObra.
public String geraFotosObra (int idObra) throws Exception { ...
Yet when you call the method in your jsp you are passing an an object literal containing a callback function.
PainelEarthAjax.geraFotosObra({
callback : function(kmlString) { ...
As it is I don't see how the kml is generated, unless perhaps geraFotosObra is an overloaded method? Also even if it was generated, as is, I don't see how the callback function that you pass in place of an id is ever called - why for example would kmlString be the result of the call to geraFotosObra?
// How is this called, what sets kmlString!?
callback : function(kmlString) {
var kmlObject = ge.parseKml(kmlString);
ge.getFeatures().appendChild(kmlObject);
}
All in all the code you posted is a wee bit confusing, so sorry if I have missed something...I think you have possibly copy and pasted some code from a fetchKml example and the asynchronous callbacks used with that method have confused you slightly.
Anyhow, based on what you have posted, you should be passing an int id to the geraFotosObra method, getting the string result and then parsing it in the plug-in.
Something like the following makes sense. Replace the showPics function with the following.
function showPics(ge) {
var kmlString = PainelEarthAjax.geraFotosObra(1); // or something?
var kmlObject = ge.parseKml(kmlString);
ge.getFeatures().appendChild(kmlObject);
}
Is there a way to set the enconding for the object requestBuilder. I have this code, which adds paramters to an URL. But when I add some character from the ISO-Latin I dont get the correct enconding:
while(kvEnum.hasMoreElements()) {
KeyValue kv = (KeyValue) kvEnum.nextElement();
String key = kv.key;
String value = kv.value;
System.out.println("######param added - "+ "key: "+key + ", value: "+value);
requestBuilder = requestBuilder.appendQueryParameter(key, value);
}
Documentation for requestBuilder.appendQueryParameter(key, value); says that encodes, but not which type of coding is using.
