Web Services :: Java Code To Generate Curl Get Http Request
Apr 6, 2015
I am trying to generate this request with my Java program, but I just can't seem to figure it out: curl -v -H "Authorization:Basic MY_AUTH_CODE" -H "Accept:application/xml" -H "app_id:MY_APP_ID" -H "app_key:MY_APP_KEY" -X GET "THIRD_PARTY_URL"
I tried to generate a query string, but I keep getting 403 errors. I also tried to input my parameters using URLConnection.getRequestProperty("name", "value"), but that didn't work either.
1. Does a GET HTTP request contain a request body? If yes what is contained in it? Are the request headers also part of the request body? 2. Is it possible to send a byte array as part of the GET request in its body? 3. Is there a size limitation on the data that can be sent via a GET request?
Are the WebDAV extensions related to REST principles? What I mean by that is, REST is an abstraction of the WWW architecture and the WebDAV is just an extension to the HTTP. So can we say that when I speak in terms of REST API's, I can restrict myself to HTTP and not HTTP extensions like WebDAV?
I would like to know the details about how a server handles a multipart request. I know that a webserver comprises of a HTTP adapter(which is responsible for receiving http requests and sending http responses) and a container(which is responsible for handling dynamic requests).
So, when a client sends a request, the HTTP adapter receives it. Then transfers the request to the container if the http adapter cannot handle it(jsps, servlets for example).
Suppose, a client sends a multipart request which has an avi file of size upto 100mb. For example, lets assume that the client takes 5 minutes to upload the file.
Lets also assume that my application is only interested in flv files. Is there any way to stop/terminate the multipart request before the file is transferred to the server? So that the client's time will not be wasted?
I think that the HTTP adapter will transfer the request to the container only after receiving the entire request, i.e. the servlet will be called only after the file is transferred to the server from client. Is it right?
If its right then there is no easy way to terminate the multipart request unless the entire file is transferred to the server. Is this right?
I want to print RAW Request Response XML to console. I have created the stubs using wsdl2java axis2. wsdl2java has created 2 java files, one for stub and one for callbackhandler.
I am trying with below method but getting null value for
operationContext.getMessageContext("Out") / operationContext.getMessageContext("In");. public void SOAPLogHandler(Stub stub){
//**** Enable the Cache to hold the last operation OperationContext OperationContext = new OperationContext(); boolean cacheLastOperationContext = true; OperationContext.setComplete(true); // Enable the Cache value serviceConxt.setCachingOperationContext(cacheLastOperationContext); serviceConxt.setLastOperationContext(OperationContext);
I am calling a SOAP based webservice using JAX-WS and a client jar. I want to get a request and response somehow and save it for audit purposes. How I can do this?
When I google it, only Handlers come up, but, as far as I understand, it is not applicable on client side.
I have been trying to implement custom request method in HTTP header while posting my data to the server URL. My application specific URL accepts -X parameter and -d for the data and it is mandatory for that url. Basically I am trying to dump JSON data into my influx DB using CURL command which is working fine from the shell. But the issue is, if I am implementing the same in java with proper approach, it is not supported or working. My CURL command is :
curl -X POST -d '<my_json_data>' '<my_url>'
How can I implement the same in java using HttpUrlConnection or other available approach?
I generated a WebService from a WSDL using JAXWS and import the finally generated WSDL to my SOAPUI to send out the request and view the response. For some reason, I always have to set WSS TimeToLive as 1000 in the request properties, else I get an error in the response. Now, I generated a client from the WSDL. I wonder if I need to set the WSS TimeToLive here as well
I have an apache server with rest APIs accepting Json object and produce Json object.testing the sever using Chrome advanced rest client show no problems.I then tried to create a jave client, using org.jboss.resteasy:
public T sendPostRequest(String url, T input) throws Exception { ClientRequest request = getNewClientRequest(url); ObjectMapper om = new ObjectMapper(); final String body = om.writeValueAsString(input); request.body(MediaType.APPLICATION_JSON, body); final ClientResponse<String> responseObj = request.post(String.class); validateResponseString(url, responseObj); String responseString = responseObj.getEntity(String.class); responseObj.releaseConnection();
I was a bit confused of the code generated by the Axis2 Code Gen.
I have created a logIn(String username, String password) method in my service and used Axis2 Code Gen to generate the Stub.
I try to access the logIn method from my Client using the Stub like below:
TestServiceStub stub = new TestServiceStub("http://localhost:8080/axis2/services/TestService"); String test = stub.logIn("user","pass").
but instead of UserName and password as the parameters, the Stub created a Login object as the parameter for the logIn method. like the one below:
stub.logIn(Login login1);
I wanted to try the logIn method by providing a static userName and password but it seems impossible because the Stub changed the parameter for the logIn method.
I created the WSDL first in RSA and then created the java bean skelaton from the WSDL. There are a couple of dateTime fields in the WSDL that are created as GregorianCalendar objects.
When I test with SOAPui and the date fields are passed correctly, everything works great. But when there is an invalid date format or anything else in the SOAP request, instead of returning a Conversion exception or some other validation exception, the field is passed as a null to the request object in the SOAP IMPL. Should't this return an exception?
Sample requests inputs: <endTimeStamp>2014-01-28T01:30:14.474Z</endTimeStamp> - Date <endTimeStamp>06-FEB-14 01.51.00.000000000 AM</endTimeStamp> - Null <endTimeStamp>Any other string be it a date or not.</endTimeStamp> - Null
I am trying to write a webservice class which actually handles multipart requests. T client will try to upload zip or tar.gz files which may be upto 1GB in size.
I dont want to validate the extension i client side.
I want to validate the file extension in server side and discard the request before the file is uploaded.
I'm developing a SOAP client and have used wsimport to generate the classes, etc. and all is going pretty well, but the server requires several headers that I've been coding up manually, specifically wise:Security and o:Security blocks. While this is a valid approach, I think I'm probably doing things the hard way and I know .NET (SOAP being an MS standard originally) has some really powerful code to generate these headers. Does java have any similar counterparts? As an example, I'm writing code like the following:
I would like to access a third party websevice using a Java client that I generated with JAX-WS wsimport, based on the WSDL provided (I am using a Maven plugin).
For quite a while I was unable to retrieve a useful response, not in the Java client and also not in SoapUI, until I found out that I had to enable WS-A on the request. In SoapUI this now results in the expected response, but what must I do to also 'enable' WS-A in the Java client? Do I maybe have to alter the WSDL, or add a parameter to wsimport?
I found some documentation on WS-A online, but so far could not find an answer.
I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
I have java http client which sends periodically (every 30 sec; this code is run by heartbeat thread in the cycle) heartbeats:
private PostResponse post(String jSessionCookie, final String action, final String data, final int postTimeoutMs) throws IOException, SSYSException { final HttpURLConnection httpConn = openHttpUrlConnection(true, postTimeoutMs, jSessionCookie); final OutputStream os = httpConn.getOutputStream(); try (final PrintWriter wr = new PrintWriter( DefaultProperty.isEnableSocketTraceGW ? new TracerOutputStream(os) : os ))
[Code] .....
On the server side there is Tomcat 8.0.21 + APR connector. Every time this heartbeat is sent I see in the Wireshark and EtherDetect that new TCP connection is opened (SYN-SYNACK packets) and after getting response from Tomcat connection is closed (FIN – FINACK packets). I was expecting that TCP connections will be reused but not closed.
i want to generate n number of pdf here n will be some limit according to requirement so ultimately I have to generate more than 1 pdf same time with once running the code I Have some values associated with id i want to print those values with respective id's in pdf format, values can be in database or in some variable , which way i should go... i have some ideas either i can save those values in database and can make a single xml file from database of all records and then divide each node with different different pdf or directly get the values from database and generate the pdf.
I have a wsdl file and already generated a java class in it. However I can't find a setter method in it. I tried invoking the getter method but it returns a null. How can I set a value in that property?
I need to generate a file in Java with Unix TimeStamp. Want to generate an ordered list of Data entry objects for a defined period of time e.g., getData (long startTimeStamp, endTimeStamp, long resolution).
1) I would like to generate resolution with random numbers by using Random class.
2) How to take Start and end timestamps to generate a file (i.e., writing into a file).
I am currently concentrating on Java programming skills. Right now developing a Energy usecase in Java with Spring framework. Have business requirement to generate data along with outliers. For example, have two parameters called as min and max (centigrates). Generate a file between min and max and store in a file. Atleast need to generate 10 outliers in each 100 records. Outliers should be < min and > max. How to write a java class with this business condition. The file should be like,
Java Code:
Public class DataGeneration(int min, int max) where min = 30 max = 50
