QT学习05：qt客户端访问java环境服务端

一、ｊａｖａ服务端代码：

package example;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.xml.ws.Endpoint;

@WebService()
public class HelloWorld {
  @WebMethod
  public String sayHelloWorldFrom(String from) {
    String result = "Hello, world, from " + from;
    System.out.println(result);
    return result;
  }

  @WebMethod
  public String getValue(String name) {
    System.out.println("客户端访问者： "+ name);
    return "客户端访问者： "+ name;
  }

  public static void main(String[] argv) {
    Object implementor = new HelloWorld ();
    String address = "http://localhost:9000/HelloWorld";
    Endpoint.publish(address, implementor);
    System.out.println("服务端成功启动！");
  }
}

二、Ｑｔ客户端主要步骤：

1）下载gsoap2.8版本备用。

2）用gsoap工具里gsoapbinwin64下的wsdl2h.exe操作＂ｕｒｌ？ｗｓｄｌ＂（进入wsdl2h.exe所在目录的cmd下执行下面），得到包含所有服务端方法的头文件（自己命名为mySoap.h）。

wsdl2h -o mySoap.h http://localhost:9000/HelloWorld?wsdl

3）用gsoap工具里gsoapbinwin64下的soapcpp2.exe操作mySoap.h即可得到一系列相关的文件，新生成的都剪切到新建文件夹mygsoap内；再将gsoap下的stdsoap2.ｈ、stdsoap2.cpp复制到mygsoap。

soapcpp2.exe mySoap.h

3）新建Qｔ客户端项目TheClient，将mygsoap放这个项目文件下面。在.ｐｒｏ文件下引入上文生成的所需文件（ soapC.cpp、soapClient.cpp、stdsoap2.cpp）。

QT -= gui

CONFIG += c++11

TARGET = NewClient
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

SOURCES += 
        main.cpp 
        mygsoap/soapC.cpp 
      　mygsoap/soapClient.cpp 
        mygsoap/stdsoap2.cpp 

# The following define makes your compiler emit warnings if you use
# any feature of Qt which as been marked deprecated (the exact warnings
# depend on your compiler). Please consult the documentation of the
# deprecated API in order to know how to port your code away from it.
DEFINES += QT_DEPRECATED_WARNINGS

# You can also make your code fail to compile if you use deprecated APIs.
# In order to do so, uncomment the following line.
# You can also select to disable deprecated APIs only up to a certain version of Qt.
#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0

INCLUDEPATH +=./mygsoap

#解决部分编译问题
LIBS += D:QtQt5.9.0Toolsmingw530_32i686-w64-mingw32liblibws2_32.a

4）在main.cpp调用服务端暴露出来的接口方法（这里调用getValue()）。

#include 
#include "soapH.h"  // include the generated source code headers
#include "HelloWorldPortBinding.nsmap" // include XML namespaces
#include

using namespace std;

int main(int argc, char *argv[])
{
    struct soap _soap;
    soap_init(&_soap);
    soap_set_mode(&_soap,SOAP_C_UTFSTRING);  //解决gsoap中文乱码问题
    // return =""; //SOAP返回值，若不为0则表示调用出错
    QString errStr = ""; //出错提示
    QString strRes = ""; //结果字符串

    //request和response
    ns1__getValue req;
    ns1__getValueResponse res;

    //填充参数
    string a="chq";
    req.arg0=&a;
    const char *point=NULL;
    const char *ction=NULL;

    //调用SOAP　　　／＊soap_call___ns1__接口＊＊／
    if(soap_call___ns1__getValue(&_soap,point,ction, &req, res)== SOAP_OK){

        qDebug()<<"访问成功！";
    }

    if(_soap.error != 0){
        //获取错误提示
        errStr = QString::fromLocal8Bit(*soap_faultstring(&_soap));
    }
    else {
        //获取结果字符串
        strRes = res.return_->c_str();
        qDebug()< 
 
5）结果
