I am connecting black box backend, I have no control over the source and cannot modify the backend, using Ok Http 3. But for some reason, I am getting two results and I don't know what's going on. I suspect two threads are becoming active. But I don't know how to stop it. I tried both Synchronous and Asynchronous connection to no effect. I am new to Ok Http 3, so I am not sure what I am doing wrong.
I/Results: {"TotalResultsCount":3,"Results":[{
I/Results: {"TotalResultsCount":24,"Results":[
Here's is my synchronous code
class CallBackendSync extends AsyncTask {
OkHttpClient client = new OkHttpClient();
JSONObject resultsObject = null;
#Override
protected Object doInBackground(Object [] objects) {
String searchTerm = (String) objects[0];
String url = (String) objects[1];
String token = (String) objects[2];
String results = "";
//Search Body
RequestBody searchBody = new FormBody.Builder()
.add("QueryText", searchTerm)
.add("Categories", "")
.add("ChargeOutPerMinuteFrom", "0")
.add("ChargeOutPerMinuteTo", "0")
.add("maxDistance", "0")
.add("longitude", "0")
.add("latitude", "0")
.add("page", "0")
.build();
//Create request
Request.Builder builder = new Request.Builder();
builder.url(url);
builder.addHeader("Accept", "application/json");
if (token != null) {
builder.addHeader("Authorization", token);
}
builder.post(searchBody);
Request request = builder.build();
try {
Response response = client.newCall(request).execute();
results = results + response.body().string();
resultsObject = new JSONObject(results);
Log.i("Results", results);
return resultsObject;
}catch (Exception e){
e.printStackTrace();
}
return null;
}
protected void onPostExecute(String s){
super.onPostExecute(s);
displayResults(resultsObject);
}
}
I am calling the backend from MainActivity using the code fragment below
CallBackendSync sync = new CallBackendSync();
String [] params = {searchTerm, serverBaseUrl + url, accessToken};
sync.execute(params);
Any ideas about what's going wrong will be much appreciated.
I have create Java Classes from the DHL WSDL
https://cig.dhl.de/cig-wsdls/com/dpdhl/wsdl/geschaeftskundenversand-api/2.2/geschaeftskundenversand-api-2.2.wsdl.
Now i have all Classes, but no Authentifaction Class.
I try this
GKVAPIServicePortTypeProxy port2 = new GKVAPIServicePortTypeProxy();
port2.setEndpoint("https://cig.dhl.de/services/sandbox/soap");
CreateShipmentOrderRequest sh = new CreateShipmentOrderRequest();
//Setting up shipment;
.. and so on
CreateShipmentOrderResponse chr = port2.createShipmentOrder(sh);
But only what i get is, "(401)Authorization Required"
How can i set my Authentifiaction ?
Hi I h had fixed the 401 problem with adding of the ssl certificate from DHL to my application truststore.
But I have the problem that I missing to add the Authentification block to the request.
<soapenv:Header>
<cis:Authentification>
<cis:user>user</cis:user>
<cis:signature>password</cis:signature>
</cis:Authentification>
</soapenv:Header>
My try to adding this block resulting in a 'org.quartz.jobexecutionexception: de.vps.icms.exceptions.icmsscriptingexception: java.lang.noclassdeffounderror: org/apache/axis2/saaj/soapenvelopeimpl'exception.

Using basic authentication, you would first Base64 encode your username:password - there's online sites that will do it but beware as likely not a good idea to do it if it refers to DHL in anyway, e.g. they could swipe your credentials.
You then get the Request Context of the port, create a map of the headers and add an Authorization header. Finally you add that back to the request context.
Example:
Note, I purposely generated bad base64 encoding so you would likely not be able to decode it and see it properly formatted with the "username:password"
GVAPI20De service1 = new GVAPI20De();
GKVAPIServicePortType port2 = service1.getGKVAPISOAP11Port0();
CreateShipmentOrderRequest sh = new CreateShipmentOrderRequest();
//Setting up shipment;
Map<String, Object> req_ctx = ((BindingProvider)port2).getRequestContext();
//you may not need this and can try commenting it out
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, "https://cig.dhl.de/cig-wsdls/com/dpdhl/wsdl/geschaeftskundenversand-api/2.2/geschaeftskundenversand-api-2.2.wsdl");
//optional timeout
req_ctx.put("javax.xml.ws.client.connectionTimeout", "60000");
Map<String, List<String>> headers = new HashMap<String, List<String>>();
headers.put("Authorization", Collections.singletonList("Basic c3gh567sd4689k11lg=="));
req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);

I use okhttp to be my httpclient. I think it's a good api but the doc is not so detailed.
how to use it to make a http post request with file uploading?
public Multipart createMultiPart(File file){
Part part = (Part) new Part.Builder().contentType("").body(new File("1.png")).build();
//how to set part name?
Multipart m = new Multipart.Builder().addPart(part).build();
return m;
}
public String postWithFiles(String url,Multipart m) throws IOException{
ByteArrayOutputStream out = new ByteArrayOutputStream();
m.writeBodyTo(out)
;
Request.Body body = Request.Body.create(MediaType.parse("application/x-www-form-urlencoded"),
out.toByteArray());
Request req = new Request.Builder().url(url).post(body).build();
return client.newCall(req).execute().body().string();
}
my question is:
how to set part name? in the form, the file should be named file1.
how to add other fields in the form?
Here is a basic function that uses okhttp to upload a file and some arbitrary field (it literally simulates a regular HTML form submission)
Change the mime type to match your file (here I am assuming .csv) or make it a parameter to the function if you are going to upload different file types
public static Boolean uploadFile(String serverURL, File file) {
try {
RequestBody requestBody = new MultipartBody.Builder().setType(MultipartBody.FORM)
.addFormDataPart("file", file.getName(),
RequestBody.create(MediaType.parse("text/csv"), file))
.addFormDataPart("some-field", "some-value")
.build();
Request request = new Request.Builder()
.url(serverURL)
.post(requestBody)
.build();
client.newCall(request).enqueue(new Callback() {
#Override
public void onFailure(final Call call, final IOException e) {
// Handle the error
}
#Override
public void onResponse(final Call call, final Response response) throws IOException {
if (!response.isSuccessful()) {
// Handle the error
}
// Upload successful
}
});
return true;
} catch (Exception ex) {
// Handle the error
}
return false;
}
Note: because it is async call, the boolean return type does not indicate successful upload but only that the request was submitted to okhttp queue.
Here's an answer that works with OkHttp 3.2.0:
public void upload(String url, File file) throws IOException {
OkHttpClient client = new OkHttpClient();
RequestBody formBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("file", file.getName(),
RequestBody.create(MediaType.parse("text/plain"), file))
.addFormDataPart("other_field", "other_field_value")
.build();
Request request = new Request.Builder().url(url).post(formBody).build();
Response response = client.newCall(request).execute();
}
Note: this answer is for okhttp 1.x/2.x. For 3.x, see this other answer.
The class Multipart from mimecraft encapsulates the whole HTTP body and can handle regular fields like so:
Multipart m = new Multipart.Builder()
.type(Multipart.Type.FORM)
.addPart(new Part.Builder()
.body("value")
.contentDisposition("form-data; name=\"non_file_field\"")
.build())
.addPart(new Part.Builder()
.contentType("text/csv")
.body(aFile)
.contentDisposition("form-data; name=\"file_field\"; filename=\"file1\"")
.build())
.build();
Take a look at examples of multipart/form-data encoding to get a sense of how you need to construct the parts.
Once you have a Multipart object, all that's left to do is specify the right Content-Type header and pass on the body bytes to the request.
Since you seem to be working with the v2.0 of the OkHttp API, which I don't have experience with, this is just guess code:
// You'll probably need to change the MediaType to use the Content-Type
// from the multipart object
Request.Body body = Request.Body.create(
MediaType.parse(m.getHeaders().get("Content-Type")),
out.toByteArray());
For OkHttp 1.5.4, here is a stripped down code I'm using which is adapted from a sample snippet:
OkHttpClient client = new OkHttpClient();
OutputStream out = null;
try {
URL url = new URL("http://www.example.com");
HttpURLConnection connection = client.open(url);
for (Map.Entry<String, String> entry : multipart.getHeaders().entrySet()) {
connection.addRequestProperty(entry.getKey(), entry.getValue());
}
connection.setRequestMethod("POST");
// Write the request.
out = connection.getOutputStream();
multipart.writeBodyTo(out);
out.close();
// Read the response.
if (connection.getResponseCode() != HttpURLConnection.HTTP_OK) {
throw new IOException("Unexpected HTTP response: "
+ connection.getResponseCode() + " " + connection.getResponseMessage());
}
} finally {
// Clean up.
try {
if (out != null) out.close();
} catch (Exception e) {
}
}

I would like to migrate from Commons HttpClient (3.x) to HttpComponents Client (4.x) but having difficulty how to handle redirects. The code works properly under Commons HttpClient but breaks when migrated to HttpComponents Client.

connectionManager = new MultiThreadedHttpConnectionManager();

I won't want redirects but under HttpClient 4.x if I enable redirects then I get some that are undesirable, e.g. http://www.walmart.com/ => http://mobile.walmart.com/. Under HttpClient 3.x no such redirects happens.
What do I need to do to migrate HttpClient 3.x to HttpClient 4.x without breaking the code?
It is not the issue with HttpClient 4.x, might be the way target server handle the request, since the user agent is httpclient, it may be handled as mobile (target server may consider other than available browsers like, i.e, chrome, mozilla etc as mobile.)
Please use below code to set it manually
httpclient.getParams().setParameter(
org.apache.http.params.HttpProtocolParams.USER_AGENT,
"Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2"
);
Does anyone know if there is a Google Reader service call that a user can make to get the name/uri of all feeds that fall under a certain label/category? Thanks!
You can use a variation of the code below to get access to the Google Reader system. You need to send the header ("Authorization", "auth=" +myauthvar) with each request. In order to edit items you will need the token which I also demo below. Once you have the auth id you can post (with that header intact) to http://www.google.com/reader/api/0/subscription/list?output=xml in order to return the full subscription listing.
