Question

我需要在我的b4a项目中添加一个web服务..请帮助我，我真的不知道该怎么做..我已经尝试了https://www.b4x.com/android/forum/threads/how-call-a-web-services-in-b4a.10577/和https://www.b4x.com/android/forum/threads/web-service-consume-in-b4a.17446/但它确实如此工作

Answer 1

您的网络服务是什么？（Soap或Restful或XmlRPC）

对于肥皂用户https://www.b4x.com/android/forum/threads/soap-is-easier-with-soap-class.56164/#content

对于XmlRPC，请使用https://www.b4x.com/android/forum/threads/manage-xmlrpc-with-okhttputils-easily-b4x.82527/#content

为了安静使用OkHttp也

Answer 2

你可以使用httpjob。将这两个库添加到您的b4a：Okhttp和okhttputils2。搜索b4x论坛获取httjob示例。

Dim job1 As HttpJob
DIm SoapXML  As String= your xml here
job1.Initialize("Job1", Me)
job1.poststring (webserviceaddress, SoapXML)
job1.GetRequest.SetContentType("text/xml")

你可以在jobdone事件上获得结果。并使用saxxmlparser库解析它

 Sub JobDone (Job As HttpJob)
   If Job.Success = True Then
           parser.Parse(Job.GetInputStream ,"Parser")
       Else
      Log("Error: " & Job.ErrorMessage)
      End If
   Job.Release
End Sub

Sub Parser_EndElement (Uri As String, Name As String, Text As StringBuilder)

 ...
End Sub
