>我需要为我的b4a项目添加一个网络服务..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/但它不起作用

Answer 1

您的网络服务是什么？(肥皂或休息或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

为了休息使用OkHttp也

Answer 2

你可以使用 httpjob 。 将这两个库添加到您的 b4a 中：Okhttp 和 okhttputils2 。 搜索 B4X 论坛以获取 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")

您可以在 jobdone Event 上获取结果，并使用 SaxXML解析器库对其进行解析

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
