SAP Netweaver.C++ 错误:无法读取内存

SAP Netweaver. C++ Error:The memory cannot be read

本文关键字：读取 内存 Netweaver C++ 错误 SAP      更新时间：2023-10-16

对于我的项目，我需要测试路由器字符串是否使用 SAP Netweaver 7.0 成功连接到 SAP 服务器。我在Visual Studio 2017中创建了一个控制台应用程序。我已经给出了连接参数。但应用程序以错误结束：无法读取内存

#include <stdlib.h>
#include <stdio.h>
#include "stdafx.h"
#include "include/sapnwrfc.h"

void errorHandling(RFC_RC rc,  RFC_ERROR_INFO*errorInfo, RFC_CONNECTION_HANDLE connection) {
    printfU(cU("%s:  %sn"), errorInfo->key, errorInfo->message);
    /* It's better to close the TCP/IP connection cleanly, than tojust let the backend get a "Connection reset by peer" error...*/
    if (connection != NULL)  RfcCloseConnection(connection, errorInfo);
    exit(1);
}

int mainU(int argc, SAP_UC** argv)
{
    RFC_RC  rc = RFC_OK;   
    RFC_CONNECTION_PARAMETER  loginParams[6];  
    RFC_ERROR_INFO  errorInfo;   
    RFC_CONNECTION_HANDLE  connection;
    //  -----------------------------------------------
    //  OPEN CONNECTION
    //  -----------------------------------------------
    //  Create logon parameter list
    loginParams[0].name = cU("gwhost");
    loginParams[0].value = cU("80.**.***.**");
    loginParams[1].name = cU("sysnr");
    loginParams[1].value = cU("00");
    loginParams[2].name = cU("client");
    loginParams[2].value = cU("800");
    loginParams[3].name = cU("user");
    loginParams[3].value = cU("jsar12");
    loginParams[4].name = cU("lang");
    loginParams[4].value = cU("EN");
    loginParams[5].name = cU("****");
    loginParams[5].value = cU("Abc");
    //  Open connection
    connection = RfcOpenConnection(loginParams, 6, &errorInfo);
    if (connection == NULL) errorHandling(rc, &errorInfo, NULL);
    return 0;
}

预期结果： 连接到 SAP 路由器

上述问题的解决方案是在Visual Studio的设置中。经过大量搜索和尝试了一些技巧，我在以下链接中找到了解决方案：https://answers.sap.com/questions/12367200/netweaver-rfc-connector-error-logon.html

总结：

On Linux and Windows, certain minimum releases of the C runtime are required to execute the programs. See SAP Notes 1021236 (for Linux) and 684106 (for Windows). The compiler and linker options needed to compile programs using the SAP NetWeaver RFC SDK are listed in SAP Note 1056696.
In addition, for Windows users using Microsoft Visual Studio, this is a description of how to set the Visual Studio project properties:
General section: Make sure the CharacterSet field is set to “Use Unicode Character Set.”
Debugging section: Under Environment, add something like Path=%Path%;nwrfcsdklib.
C/C++ section:
General: Add the nwrfcsdkinclude directory under Additional Include Directories.
Preprocessor: Add the two preprocessor definitions SAPonNT and SAPwithUNICODE.
Code Generation: Choose “Multi-threaded DLL (/MD)” as the Runtime Library; selecting “Multi-threaded Debug DLL (/MDd)” may lead to strange problems.
Linker section:
General: Add the nwrfcsdklib directory under Additional Library Directories.
Input: Under Additional Dependencies, add libsapucum.lib, sapnwrfc.lib, and sapdecfICUlib.lib
