PB程序通过http调用servlet

来源：互联网发布：导入js包到包报错编辑：程序博客网时间：2024/05/15 12:22

1、准备pslib21.dll

2、得到http url

3、发送http请求

4、得到返回值

eg:

instance variables:

constant string is_HttpIP = '192.168.0.97'
constant string is_HttpPort = '8080'

//取httpurl

of_gethttp()

string ls_httpurl

ls_httpurl = "http://" + is_HttpIP + ":" + is_HttpPort;

return ls_httpurl

//发送HTTP请求

of_posthttpreq(as_strreqdata, as_strurl)

string ls_Result
OLEObject Header

Header = CREATE OLEobject
if Header.ConnectToNewObject("Dart.DartStrings") < 0 then
MessageBox("Fatal Error","Could not create DartStrings object")
return "false"
end if

ole_Http.object.Url = as_strurl
ole_Http.object.Timeout = 180000

// Post the assembled string
ole_Http.object.Post(as_strreqdata, Header, REF ls_Result)

//错误处理
if nError <> 0 then
ls_Result = string(nError) + " : " + sError + ls_Result

if nError = httpTimeout then
MessageBox("错误:","网络超时,请与系统管理员联系!")
else
MessageBox("其他错误:","Error #" + ls_Result)
end if
end if

return ls_Result
