I want to send JSON object / JSON Array to .net Serverusing KSOAP library.
Here is my code
sendJSON{
JSONObject json = new JSONObject();
try {
CallingSoap cs=new CallingSoap();
String macid="1";
String latStr= StaticVariableClass.latitude_str;
String longStr= StaticVariableClass.longitude_str;
String datetimeStr="23/04/2015";
json.put("MacID",macid);
json.put("DateTime",datetimeStr);
json.put("Latitude",latStr);
json.put("Longitude",longStr );
String JSONString= json.toString();
Log.e("JSON", JSONString);
// String resp=cs.demo("test");
String resp=cs.demo(json); // I need to send this json to my asp.net web server
Log.d("Response from server",resp);
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
//CallingSoap .java
public class CallSoap {
public String demo(JSONObject a)
//public String demo(String a)
{
final String SOAP_ACTIONS= "http://tempuri.org/GetLatLongJson";
final String OPERATION_NAMES= "GetLatLongJson";
final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
final String SOAP_ADDRESS = "http://10.208.36.33/samtadoot2/samtadootwebservice.asmx";
SoapObject request=new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAMES);
PropertyInfo pi=new PropertyInfo();
pi.setName("jsonobject");
pi.setValue(a);
pi.setType(JSONObject.class);
request.addProperty(pi);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
new MarshalBase64().register(envelope);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
Object response=null;
try
{
httpTransport.call(SOAP_ACTIONS, envelope);
response = envelope.getResponse();
}
catch(Exception ex)
{
response=ex.toString();
}
//JSONArray JSONArray = null;
return response.toString();
}
}
it is throwing an exception of cannot seralize
04-27 12:52:46.378: D/Response from server(5982): java.lang.RuntimeException: Cannot serialize: {"MacID":"1","Latitude":"18.5647613","Longitude":"73.8069672"}
Thanks in advance
that:
pi.setType(JSONObject.class);
will not work, becouse there is no standard serialization defined for JSONObject in ksoap2. But what i suppouse what You didnt written is that You try to send JSON string to theserver. It i'm right, then You have to change Your code to send String and encode JSONObject to JSON string using toString this way:
SoapObject request=new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAMES);
PropertyInfo pi=new PropertyInfo();
pi.setName("jsonobject");
pi.setValue(a.toString());
pi.setType(String.class);
request.addProperty(pi);
If i'm wrong, then You have to parse whole JSONObject to structure of SoapObjects/Primitives.

I have been looking around for sample code how to call a Restful service written in Spring boot (deployed in different server/ip) from an EJB client.
I couldn't find a simple example or reference to guide me on how to implement an EJB client that can call a restful service(deployed in different server/ip). Could you please point me to a document or example that shows or describe how the two can interface/talk to each other.
I need to call the endpoint by passing two header parameters for authentication, if authentication is success then only retrieve the details from Rest and send back the response to EJB client.
I use something like this, try
`public void calExternal() throws ProtocolException,
MalformedURLException,
IOException,
NoSuchAlgorithmException,
InvalidKeyException {
URL myurl = new URL("API END POINT URL");
ObjectMapper mapper = new ObjectMapper();
HttpURLConnection conn = (HttpURLConnection) myurl.openConnection();
conn.setUseCaches(false);
conn.setDoInput(true);
conn.setDoOutput(true);
String payLoad = mapper.writeValueAsString("your payload here");
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("AUTHORIZATION-TYPE", "HMAC");
try {
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(payLoad);
wr.flush();
InputStream in = null;
int responseCode = conn.getResponseCode();
if (responseCode == 200) {
in = conn.getInputStream();
} else {
in = conn.getErrorStream();
}
String encoding = conn.getContentEncoding() == null ? "UTF-8" : conn.getContentEncoding();
String response = IOUtils.toString(in, encoding);
} catch (Exception e) {
e.printStackTrace();
}
}
First of all, I am new with Spring Boot.
I am not sure if it is possible, but I would like to return the xml response from the external url.
I have this code:
#GetMapping("/myPage")
public void myPage() {
restConfiguration().host("localhost").port(8080);
from("timer://runOnce?repeatCount=1&delay=0")
.to("rest:get:/external-page")
.to("stream:out");
}
myPage() is returning a XML (that's OK). So, now I would like to return the same XML when I do:
curl http://localhost/myPage
I am not sure if I have to use .to("stream:out"), but the curl is returning an empty result.
Can someone help me?
Thanks in advance.
I found the solution, this is how to get the response.
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
public void configure() {
restConfiguration().host(sHost).port(iPort);
from("direct:start")
.setHeader(Exchange.HTTP_METHOD,simple("GET"))
.to("rest:get:/external-page");
}
});
context.start();
ProducerTemplate template = context.createProducerTemplate();
String headerValue = "application/xml";
Map<String, Object> headers = new HashMap<String,Object>();
headers.put("Content-Type", headerValue);
Object result = template.requestBodyAndHeaders("direct:start", null, headers, String.class);
Exchange exchange = new DefaultExchange(context);
String response = ExchangeHelper.convertToType(exchange, String.class, result);
context.stop();
return response;
My Controller use " org.apache.commons.fileupload " realized the file UPload.
see it:
#PostMapping("/upload")
public String upload2(HttpServletRequest request) throws Exception {
ServletFileUpload upload = new ServletFileUpload();
FileItemIterator iter = upload.getItemIterator(request);
boolean uploaded = false;
while (iter.hasNext() && !uploaded) {
FileItemStream item = iter.next();
if (item.isFormField()) {
item.openStream().close();
} else {
String fieldName = item.getFieldName();
if (!"file".equals(fieldName)) {
item.openStream().close();
} else {
InputStream stream = item.openStream();
// dosomething here.
uploaded = true;
}
}
}
if (uploaded) {
return "ok";
} else {
throw new BaseResponseException(HttpStatus.BAD_REQUEST, "400", "no file field or data file is empty.");
}
}
and my MockMvc code is
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
MockMultipartFile multipartFile = new MockMultipartFile("file", new FileInputStream(file));
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", "----WebKitFormBoundaryaDEFKSFMY18ehkjt");
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.post(baseUrl+"/upload")
.content(multipartFile.getBytes())
.contentType(mediaType)
.header(Origin,OriginValue)
.cookie(cookie))
.andReturn();
logResult(mvcResult);
}
my controller is right , it has successed in my web project,
but I want to test it use MvcMock, it has some mistake, see :
can someOne can help me?
"status":"400","msg":"no file field or data file is empty.","data":null
I don't know why it says my file is empty.
my English is poor, thank you very much if someone can help me.
The MockMvc can be used for integration testing for controllers using Apache Commons Fileupload too!
Import the org.apache.httpcomponents:httpmime into your pom.xml or gradle.properties
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpmime</artifactId>
<version>4.5.13</version>
</dependency>
Update the code to use MultipartEntityBuilder to build the multipart request on the client, and then serialize the entity into bytes, which is then set in the request content
public void upload() throws Exception {
File file = new File("/Users/jianxiaowen/Documents/a.txt");
String boundary = "----WebKitFormBoundaryaDEFKSFMY18ehkjt";
// create 'Content-Type' header for multipart along with boundary
HashMap<String, String> contentTypeParams = new HashMap<String, String>();
contentTypeParams.put("boundary", boundary); // set boundary in the header
MediaType mediaType = new MediaType("multipart", "form-data", contentTypeParams);
// create a multipart entity builder, and add parts (file/form data)
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
HttpEntity multipartEntity = MultipartEntityBuilder.create()
.addPart("file", new FileBody(file, ContentType.create("text/plain"), file.getName())) // add file
// .addTextBody("param1", "value1") // optionally add form data
.setBoundary(boundary) // set boundary to be used
.build();
multipartEntity.writeTo(outputStream); // or getContent() to get content stream
byte[] content = outputStream.toByteArray(); // serialize the content to bytes
MvcResult mvcResult = mockMvc.perform(
MockMvcRequestBuilders.post(baseUrl + "/upload")
.contentType(mediaType)
.content(content) // finally set the content
.header(Origin,OriginValue)
.cookie(cookie)
).andReturn();
logResult(mvcResult);
}
Can you try the below?
mockMvc.perform(
MockMvcRequestBuilders.multipart(baseUrl+"/upload")
.file(multiPartFile)
).andReturn();
Update:
You need to update the controller to handle the MultipartFile:
#PostMapping("/upload")
public String upload2(#RequestParam(name="nameOfRequestParamWhichContainsFileData")
MultipartFile uploadedFile, HttpServletRequest request) throws Exception {
//the uploaded file gets copied to uploadedFile object.
}
You need not use another library for managing file uploads. You can use the file upload capabilities provided by Spring MVC.
I have created a filter which inherits the System.Web.Http.Filters.ActionFilterAttribute in the asp.net web api and would like to access some of the data inside the HttpActionExecutedContext result object.
At what stage/when does this object get populated? As I looked at it when overriding the OnActionExecuted method and its always null?
Any ideas?
Edit:
for example here in my custom filter:
public override OnActionExecuted(HttpActionExecutedContext context)
{
//context.Result.Content is always null
base.OnActionExecuted(context);
}
Use this function to get body of request in web api
private string GetBodyFromRequest(HttpActionExecutedContext context)
{
string data;
using (var stream = context.Request.Content.ReadAsStreamAsync().Result)
{
if (stream.CanSeek)
{
stream.Position = 0;
}
data = context.Request.Content.ReadAsStringAsync().Result;
}
return data;
}
Ended up using ReadAsStringAsync on the content result.
I was trying to access the property before the actual request had finished.
While the awarded answer referred to ReadAsStringAsync, the answer had no example. I followed the advice from gdp and derived a somewhat working example...
I created a single class called MessageInterceptor. I did nothing more than derive from ActionFilterAttribute and it immediately started to intercept webAPI method calls prior to the controller getting it, and after the controller finished. Here is my final class. This example uses the XML Serializer to get both the request and response into an XML string. This example finds the request and response as populated objects, this means deserialization has already occurred. Collecting the data from a populated model and serializing into an XML string is a representation of the request and response - not the actual post request and response sent back by IIS.
Code example - MessageInterceptor
using System.IO;
using System.Linq;
using System.Web.Http.Controllers;
using System.Web.Http.Filters;
using System.Xml.Serialization;
namespace webapi_test
{
public class MessageInterceptor : ActionFilterAttribute
{
public override void OnActionExecuting(HttpActionContext actionContext)
{
base.OnActionExecuting(actionContext);
var headers = actionContext.Request.Content.Headers.ToString();
var request = actionContext.ActionArguments.FirstOrDefault().Value;
var xml = SerializeXMLSerializer(request, "");
}
public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
{
base.OnActionExecuted(actionExecutedContext);
var headers = actionExecutedContext.Response.Content.Headers.ToString();
var response = actionExecutedContext.Response.Content.ReadAsStringAsync().Result;
var xml = SerializeXMLSerializer(response, "");
}
public static string SerializeXMLSerializer(object o, string nameSpace)
{
string serializedValue;
var writer = new StringWriter();
XmlSerializer serializer = new XmlSerializer(o.GetType(), nameSpace);
serializer.Serialize(writer, o);
serializedValue = writer.ToString();
return serializedValue;
}
}
}
Use below to read Response string:
public static string GetResponseContent(HttpResponseMessage Response)
{
string rawResponse = string.Empty;
try
{
using (var stream = new StreamReader(Response.Content.ReadAsStreamAsync().Result))
{
stream.BaseStream.Position = 0;
rawResponse = stream.ReadToEnd();
}
}
catch (Exception ex) { throw; }
return rawResponse;
}
I was using PayPal helper http://paypalhelper.codeplex.com and was getting an error PayPal.Platform.SDK.FATALException
After that i took the source code too have look what is happening there and after i debug one of the tests in the test project public void TestImplicitSimplePay() and find out that it is throwing an error in the class SoapEncoder in method Decode in line 96 return (object)serializer.Deserialize(reader);
public static object Decode(string soapEnvelope, Type toType)
{
XmlSerializer serializer = null;
try
{
/// Initializing the XMLSerializer.
serializer = new XmlSerializer(toType);
/// Removing SOAP outer Envelope
soapEnvelope = soapEnvelope.Replace("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header /><soapenv:Body>", string.Empty);
soapEnvelope = soapEnvelope.Replace("</soapenv:Body></soapenv:Envelope>", string.Empty);
soapEnvelope = soapEnvelope.Replace("xmlns:ns2=\"http://svcs.paypal.com/types/ap\"", string.Empty);
soapEnvelope = soapEnvelope.Replace("ns2:", string.Empty);
soapEnvelope = soapEnvelope.Replace("soapenv:", string.Empty);
soapEnvelope = soapEnvelope.Replace("ns3:", string.Empty);
soapEnvelope = soapEnvelope.Replace("xmlns:ns2=\"http://svcs.paypal.com/types/ap\"", string.Empty);
/// Deserializing and Returning the XML
using (MemoryStream reader = new MemoryStream(Encoding.UTF8.GetBytes(soapEnvelope)))
{
return (object)serializer.Deserialize(reader); //Error here
}
}
catch (FATALException)
{
throw;
}
catch (Exception ex)
{
throw new FATALException("Error occurred in SoapEncoder->Decode method", ex);
}
finally
{
serializer = null;
}
}
soapEnvelope xml:
<xml version='1.0' encoding='utf-8'?>
<Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\">
<Header/>
<Body>
<PayResponse >
<responseEnvelope>
<timestamp>2011-08-09T00:28:53.399-07:00</timestamp>
<ack>Success</ack>
<correlationId>621854fd57929</correlationId>
<build>2012864</build>
</responseEnvelope>
<payKey>AP-1SE162159L922805T</payKey>
<paymentExecStatus>COMPLETED</paymentExecStatus>
</PayResponse>
May be some one come across that and know what i can do to fix that?
Replace this line:
soapEnvelope = soapEnvelope.Replace("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header /><soapenv:Body>", string.Empty);
With:
soapEnvelope = soapEnvelope.Replace("<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\"><soapenv:Header/><soapenv:Body>", string.Empty);
The response from Paypal seems to have altered slightly and the <soapenv:Header /> node no longer has a space before the self closing tag ends.
