一、WebService

1.提供WebService服务

1)创建%SOAP.WebService派生类，添加NAMESPACE、SERVICENAME

2)参考web.DHCANService

2.调用WebService

1)创建%SOAP.WebClient的派生类，添加LOCATION、NAMESPACE、SERVICENAME

web.DHCCLDevSoapInferface

2)参考 web.DHCCLDevSoapInferface

3)添加验证

a.HIS8.3后需要添加验证

do obj.WSSecurityLogin("dhwebservice","dhwebservice")

b.HIS8.5的均需求添加SSL验证

注意： HIS8.5的均需求添加SSL验证! URL地址由web/webservice改为: imedical/webservice

s obj.Location="https://192.168.165.24:1443/imedical/webservice/web.DHCANService.cls" 
set obj.SSLConfiguration="ANSSLConfiguration"
d obj.WSSecurityLogin("dhwebservice","dhwebservice")

注意：

二、HTTP

1.HTTP服务端

1)获取GET、POST参数

%request会将get中的URL数据，表单数据转化为%request.Data数据，因此不必写代码分别处理

Write %request.Data("A",1)、


/// 前台调用时，根据方法或Query参数调用
/// 注： 当方法或Query的参数是JSON字符串时前台需要对传入JSON字符串,比如DHCBP.Register的Save方法
Class web.DHCCLMobileInferface Extends %CSP.Page
{

ClassMethod OnPreHTTP(ByRef OutputBody As %Boolean) As %Boolean
{
	/*星号表示所有的域都可以接受，*/
	Do %response.SetHeader("Access-Control-Allow-Origin","*")
	Do %response.SetHeader("Access-Control-Allow-Methods","GET,POST")
	Do %response.SetHeader("Access-Control-Allow-Headers","x-requested-with,content-type")
	// Do %response.SetHeader("Access-Control-Allow-Headers","x-requested-with,content-type")
	//Do %response.SetHeader("Content-Type","application/pdf")
	Quit 1
}

ClassMethod OnPage() As %Status
{
	try{
		
		s msgType=%request.Data("MsgType",1)
		s params=%request.Data("Params",1)
		s clsName=%request.Data("ClassName",1)

2.HTTP客户端

1).通过%Net.HttpRequest类Post JSON数据并获取数HTTP数据

ClassMethod Post(startDate, startTime, endDate, endTime)
{
	// s startDate="2018-08-16"
	// s startTime="06:59:19"
	// s endDate="2018-08-16"
	// s endTime="07:01:14"
	// w ##class(web.DHCANOPAttendance).Post(startDate, startTime, endDate, endTime)
	s startDatetime=startDate_" "_startTime
	s endDatetime=endDate_" "_endTime
	Set httprequest=##class(%Net.HttpRequest).%New()
    //set httprequest.SSLConfiguration="MySSLConfiguration"
    set httprequest.SSLCheckServerIdentity=0 ;旧的库需要添加
    set httprequest.Https=0
    set httprequest.Server="192.9.230.90"
    set httprequest.Port=8090
    // httprequest.InsertFormData("Content-Type","text/plain")
    d httprequest.ContentTypeSet("application/x-www-form-urlencoded; charset=UTF-8;text/plain")
    d httprequest.Head("Accept-Encoding","gzip,deflate,sdch")
    d httprequest.Head("Accept-Language","zh-CN,zh;q=0.8")
    s httprequest.ContentCharset="UTF-8"
    s semicolon=""""
    set requestData="{"_semicolon_"starttime"_semicolon_":"_semicolon_startDatetime_semicolon_","
    set requestData=requestData_semicolon_"endtime"_semicolon_":"_semicolon_endDatetime_semicolon_"}"
    d httprequest.EntityBody.Write(requestData)
    set tSc = httprequest.Post("/api/v2/transaction/get/?key=a702e2gxnd81gxruy_xigjb6pnwy5pmw5gn16thq1nor")
    s strRes=""
    do{
    s res=httprequest.HttpResponse.Data.ReadLine()
    s strRes=strRes_res
    }
    while(res'="")
    
    s strRes=$ZCONVERT(strRes,"I","JSON")
    quit strRes
    
    Quit httprequest.HttpResponse
}

2). 表单提交

    Set httprequest=##class(%Net.HttpRequest).%New()
    set httprequest.SSLConfiguration="MySSLConfiguration"
    set httprequest.Https=1
    set httprequest.Server="myserver.com"
    set httprequest.Port=443
    Do httprequest.InsertFormData("portalid","2000000")
    set tSc = httprequest.Post("/url-path/")
    Quit httprequest.HttpResponse

三、HTTPS
使用HTTPS前需要在 系统 > 安全管理 > SSL/TLS 配置 添加客户端的凭据

	Set httprequest=##class(%Net.HttpRequest).%New()
    set httprequest.SSLConfiguration="MySSLConfiguration"
    set httprequest.SSLCheckServerIdentity=0 ;旧的库需要添加
    set httprequest.Https=1
    set httprequest.Server="things.icoldchain.cn"
    set httprequest.Port=443

    Do httprequest.InsertFormData("code","1520437297405")
    Do httprequest.InsertFormData("deviceSN","B7ZAU040")
    set tSc = httprequest.Post("/output/getDeviceProperties")
    s strRes=""
    do{
	    s res=httprequest.HttpResponse.Data.ReadLine()
	    s strRes=strRes_res
    }
    while(res'="")
    
    s strRes=$ZCONVERT(strRes,"I","JSON")
    quit strRes
    
    Quit httprequest.HttpResponse

三、TCP与UDP
