I am having problems with oauth. Let me start by saying that I have only been studying C++ for about a month. I am working on a Etrade API application. I have been struggling with this for a few weeks. Ok Etrade has provided the header, DLL and library files. I am having trouble just calling a simple function. Etrade list examples on how to call a Function for Java, and PHP but no C++. I just need a example for one function and I can pretty much go from there. here is a link to the API help
https://us.etrade.com/ctnt/dev-portal/getContent?contentUri=V0_Code-SDKGuides-VC
the arguments for the first function are
m_environment IN Optional. Possible values are SANDBOX (default) and LIVE.
m_strConsumerKey IN OAuth consumer key provided by E*TRADE
m_strConsumerSecret IN OAuth consumer secret provided by E*TRADE
m_strToken OUT Returned by the function if successful
m_strTokenSecret OUT Returned by the function if successful
m_strCallback IN Optional; default value is "oob"
Here is my code first function (oauth)
int main(int argc, char **argv)
{
}
bool COAuthSDK::GetRequestToken(CClientDetails &objClientDetails)
{
return GetRequestToken;
}
You're missing the point. ETrade provides you with COAuthSDK::GetRequestToken; You're supposed to call it, not re-implement it yourself. The m_ arguments are members of the CClientDetails object that you, as the client, have to provide.
Just a heads up. The Authorize URL in the docs(v0) is wrong! Doh! If you are having problems with that step, try the following URL.
Here is the correct URL: https://us.etrade.com/e/t/etws/authorize
Notice there is an additional 't' in the URL
BTW, I wrote a simple Node app called Trading Robo Monkey. If you have never used OAuth before, you can try to see if that was your problem by looking at the JS code

I am confused ,when I am following fabric-samples (asset-transfer-basic --->https://github.com/hyperledger/fabric-samples/blob/main/asset-transfer-basic/chaincode-go/chaincode/smartcontract.go) for writing smart contract in Golang , the methods takes ctx contractapi.transcationcontextinterface as there function parameter , but when I am trying to refer other chaincode's on internet every one else are taking stub shim.chaincodesubinterface as there function parameter , if I use stub as my function parameter then how can I make use of clientidenty methods (cid package) , and in asset-transfer-basic code Init/Invoke are not mentioned also in main function when creating a new chaincode ( assetChaincode, err := contractapi.NewChaincode(&SmartContract{}) ) SmartContract{} does not implement contractinterface . I am try to do a project on ERC20 token for applying for jobs so please help
The examples you have found that include an Init and Invoke function, and take ChaincodeStubInterface as a parameter are using the older and lower-level fabric-chaincode-go API directly. The asset-transfer-basic sample is using the newer and higher-level fabric-contract-api-go API. This is built on top of the lower-level API and allows you access to all the same information as the lower-level API (note that the transaction context passed into transaction functions using the higher-level API has a GetStub method to obtain the corresponding low-level ChaincodeStubInterface).
I would recommend using the Contract API as demonstrated by the asset-transfer samples. The two approaches are functionally equivalent but the Contract API provides a cleaner abstraction requiring less boiler-plate code.
Need some help with KDSoap 1.7 or gSOAP
I'm trying to use some Web Service API: http://sparkgatetest.interfax.ru/iFaxWebService/ . There is list of methods and to interact with them u must:
call Authmethod
call any method u need to
call End
Problem is, this is HTTP protocol, so if you used Authmothod succesfully, and after that trying to call methods which return some information, u got an "Authorization error" message in xml response.
So, to correct usage of this API u should call three methods (Authmethod, some method, End) in one request. How should I do it with KDSoap/gSOAP?
p.s. i found setAuthentication function in client interface, but it takes KDSoapAuthentication class as argument, maybe there is a way to customize it? And End method also a big problem aswell.
I'm using new WebRTC stats API with RTCStatsCollectorCallback object that is called when stats report is generated. I'm invoke GetStats() and then I can see that OnStatsDelivered is called with a RTCStatsReport that contains just one (empty) item in stats_ member. In GetStats() call I pass my own implementation of RTCStatsCollectorCallback that implements webrtc::RTCStatsCollectorCallback interface. My question is, is neccessary some setup or constraints in PeerConnection in order to get RTCStatsReport with the metrics? I mean, to get, for example kStatsValueNameRtt stat, I need to set something in PeerConnection. Note that I'm using C++ native API in branch 55. Is this new stats API full implemented?
I've used the older GetStats method with success:
bool GetStats(StatsObserver* observer,
webrtc::MediaStreamTrackInterface* track,
StatsOutputLevel level) override;
It could be your problem was due to trying to use an in-progress API (webrtc framework is a bit wild west). Currently, peerconnectiointernface.h says the following:
// Gets stats using the new stats collection API, see webrtc/api/stats/. These
// will replace old stats collection API when the new API has matured enough.
// TODO(hbos): Default implementation that does nothing only exists as to not
// break third party projects. As soon as they have been updated this should
// be changed to "= 0;".
virtual void GetStats(RTCStatsCollectorCallback* callback) {}
As I'm writing this response, your question is 6 months old, so it's possible the this new API is now working (though the comment above suggests otherwise).
I'm wondering the most simple way to send a request to a API on my server then receive the API's response (json array) wihtout using any libraries. I've tried using libs like cURL & boost without any luck which is the reason i want to stay away from them. I've searched for many days for a answer and have not been able to find anything, which is why i've resorted to coming to the stack overflow community!
Even though the question is about not using a library I 'am taking this opportunity to show how easy it is to use a library than the user thinks.
Its better to use pre-built libraries and stop reinventing the wheel. You can use curlcpp library. Its a wrapper for libcurl. Using this library HTTP requests can be made easily. Learning curve is also less and it provides C++ style access which makes it more comfortable to work with.
The following code is taken from their gitHub page - https://github.com/JosephP91/curlcpp
It makes a simple GET request to Google and retrieves the HTML response. You can use this example to hit apis too.
#include "curl_easy.h"
#include "curl_exception.h"
using curl::curl_easy;
using curl::curl_easy_exception;
using curl::curlcpp_traceback;
int main(int argc, const char **argv) {
curl_easy easy;
// Add some option to the curl_easy object.
easy.add<CURLOPT_URL>("http://www.google.it");
easy.add<CURLOPT_FOLLOWLOCATION>(1L);
try {
// Execute the request.
easy.perform();
} catch (curl_easy_exception error) {
// If you want to get the entire error stack we can do:
curlcpp_traceback errors = error.get_traceback();
// Otherwise we could print the stack like this:
error.print_traceback();
// Note that the printing the stack will erase it
}
return 0;
}
I am new to the wsdl\soapmessage query\reply world( if i can put it in this way), and I am facing some difficulties using the following wsdl( which I really really hope, one will be so kind to look at at least one of the services described there)
http://almdemo.polarion.com/polarion/ws/services/TrackerWebService?wsdl
which was provided to me to develop a matlab webinterface. Right now my matlab code looks like this:
targetNamespace = 'http://ws.polarion.com/TrackerWebService';
method = 'queryWorkItems';
values= {'Query','Sort'}
names = {'query', 'sort'}
types ={'xsd:string','xsd:string'}
message = createSoapMessage( targetNamespace, method, values, names, types)
response = callSoapService('http://almdemo.polarion.com/polarion/ws/services',...
% Service's endpoint
'http://almdemo.polarion.com/polarion/#/workitems',...
% Server method to run
message)
% SOAP message created using createSoapMessage
author = parseSoapResponse(response)
Herewith to save you time I will just enonce my two problems:
Is the code correct?
Could someone tell me if such a wsdl link is just a definition of webservices or it is also a service's endpoint?
Normally to execute manually\per clicks this services on the weppage
http://almdemo.polarion.com/polarion, you have to login!
So how do I send a message in matlab which first log me in? Or must such a service be introduced into that wsdl for me to do it?? Could you be kind enough to write how it must be defined, because I don't really
write wsdl files, but I shall learn!**
I will be really thankful for your help and I wish you a happy week(-end) guys(& girls)!!!
Regards
Chrysmac
ps: I tried to use Soapui and gave that webpage as endpoint, but the toool crashes each time I enter my credentials! Maybe because of the dataload!??
