Qt使用workflow

Qt工程设置

在这里插入图片描述

QMAKE_CFLAGS_DEBUG += -MTd
QMAKE_CXXFLAGS_DEBUG += -MTd

上述内容必须设置，否则会报错：error LNK2038: 检测到“RuntimeLibrary”的不匹配项: 值“MTd_StaticDebug”不匹配值“MDd_DynamicDebug。

在这里插入图片描述

libworkflow.pri的文件内容如下：

# 动态编译与静态编译不匹配
QMAKE_CFLAGS_DEBUG += -MTd
QMAKE_CXXFLAGS_DEBUG += -MTd

# OpenSSL库
INCLUDEPATH += $(OPENSSL_ROOT_DIR)/include
DEPENDPATH += $(OPENSSL_ROOT_DIR)/include
LIBS += -L$(OPENSSL_ROOT_DIR)/lib
LIBS += -llibcrypto -llibssl

# workflow
INCLUDEPATH += $$PWD/include
DEPENDPATH += $$PWD/include

CONFIG(debug, debug|release){
    LIBS += -L$$PWD/lib
    LIBS += -lworkflowd
}else{
    LIBS += -L$$PWD/lib
    LIBS += -lworkflow
}

LIBS += -lwsock32 -lws2_32

OpenSSL的配置查看上一篇文件：在Win10中使用VS2017编译workflow

使用workflow的WFHttpServer类实现一个HTTP服务器，浏览器访问时显示一个爱心界面

main.cpp

#include <iostream>
#include <fstream>
#include "workflow/WFHttpServer.h"

using namespace std;
using namespace protocol;

void http_callback(WFHttpTask *task)
{
    //读取Html文件
    ifstream ifs;
    ifs.open("web.html", ios::in);
    if(!ifs.is_open())
    {
        cout << "HTML文件打开失败" << endl;
        return;
    }

    //char content[1024 * 2] = { 0 };
    //while(!ifs.eof()){
    //    ifs.getline(content, 2048);
    //    cout << content << endl;
    //}
    //while(ifs >> content){
    //    cout << content << endl;
    //}

    std::string webStr;
    system("cls");
    std::string tmp;
    while(getline(ifs, tmp)){
        webStr += tmp;
        cout << tmp << endl;
    }
    ifs.close();

    cout << __FUNCTION__ << " " << __LINE__ << " " << webStr << endl;
    task->get_resp()->append_output_body(webStr);
}

int main()
{
    WFHttpServer server(http_callback);

    if (server.start(8888) == 0) {  // start server on port 8888
        getchar(); // press "Enter" to end.
        server.stop();
    }

    cout << "Hi Workflow" << endl;
    return 0;
}
