问题 I use shiny server to build a web-app on port 3838, when i use nginx in my server it works well. But when I stop nginx on my server and try to use docker nginx, I find the site comes to a '502-Bad Gate Way' error and nginx log shows: 2016/04/28 18:51:15 [error] 8#8: *1 connect() failed (111: Connection refused) while connecting to upstream, ... I install docker-nginx by this command: sudo docker pull nginx My docker command line is something like (for clear i add some indent): sudo docker run

问题 I'm building an Android app, which should: show some data, loaded from a server in the Internet. At the moment I have a local SQliteDB used in my app where the data is stored, which should be displayed. I use this, because I want to be able to show the data, even if there is temporarily no internet connection available. Next step I will work on inserting data in the local SQliteDB from a internet server. I thought about doing it this way: When app starts, check if internet is available. If

问题 I'm newer to web services, but I have a web service that I'm consuming/wrapping in Visual Studio C# that ends in Service.asmx where I did Add Service Reference and it pulled in all of the elements that were showing in Service.asmx?wsdl . It has objects for Username and Password that worked fine, but now the company who created this web service is changing to token authentication where I get a GUID token and pass null to these elements. Well shouldn't the web service show a new element where I

问题 There is system, that has data, and can provide it's data with web-services (for example Lotus Notes database). Can Jasper get data for it's report by calling web-service? 回答1: You can, but it will probably get very complicated very quickly. But if you want to travel that path, it is definitely possible with a JRXmlDataSource. You will have to define the datasource like: new net.sf.jasperreports.engine.data.JRXmlDataSource( net.sf.jasperreports.engine.util.JRLoader.getLocationInputStream(

问题 I hear people say as per Roy Feilding that REST is not just for web services. If so, what other systems/mechanisms/anything can use it? 回答1: The REST interface is designed to be efficient for large-grain hypermedia data transfer -- Fielding, 2000. REST is intended for long-lived network-based applications that span multiple organizations -- Fielding, 2008 The problem, of course, is that if that's what you need -- the web is sitting right there, so in most cases it's going to be more practical

问题 the problem almost like this: ASP.NET Web Service changes port on Invoke.I try to use the SoapExtensionReflector to modify the service address in WSDL,and it works on SaopAddress,but the http address is still nochanging. the result like this: - <wsdl:service name="WebService1"> - <wsdl:port name="WebService1Soap" binding="tns:WebService1Soap"> <soap:address location="http://I can remove this Port:3821/WebService1.asmx" /> </wsdl:port> - <wsdl:port name="WebService1Soap12" binding="tns

问题 So I am trying to load the data from a REST source into my Angular 6 app using http: HttpClient from '@angular/common/http' . Calling the app in the browser using ng serve --open though doesn't do the job. I assume CORS to be the problem here. I guess I either have to set the server or the client headers with Access-Control-Allow-Origin or something, but I have already tried multiple ways without any success in making this simple REST call work. So what follows below is what I coded. Calling
