如何在C ++应用程序中使用curl Nuget包

本文介绍了如何在C ++应用程序中使用curl Nuget包的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用Visual Studio 2017开发的C ++应用程序中使用curl.我喜欢使用Nuget的想法，因为它是实现库的一种非常干净的方法.我尝试遵循Microsoft论坛中的以下示例，该示例导致我使用"rmt_curl"包(在下面链接).但是，这使VS无法找到"curl.h".

I am trying to use curl in a C++ application I am developing using Visual Studio 2017. I like the idea of using Nuget because it is a very clean way of implementing a library. I tried to follow the example below from the Microsoft forum, which led me to use the "rmt_curl" package (linked below). This, however, left VS unable to find "curl.h".

rmt_curl nuget软件包: https://www.nuget.org/packages/rmt_curl/

rmt_curl nuget package:https://www.nuget.org/packages/rmt_curl/

因此，我切换为使用"curl"包，该包修复了头文件，但为每个curl函数导致了未解析的外部符号".

So I switched to use the "curl" package, which fixed the header file, but resulted in "unresolved external symbol" for each of the curl functions.

curl nuget软件包: https://www.nuget.org/packages/curl/

curl nuget package:https://www.nuget.org/packages/curl/

受其他评论和答案的启发，我将"libcurl.lib"添加到项目属性->链接器->输入->其他依赖项"列表中.这将导致无法打开文件'libcurl.lib'".

Inspired by other comments and answers I added "libcurl.lib" to the project "Properties->Linker->Input->Additional Dependencies" list. This results in "cannot open file ‘libcurl.lib’".

尝试了"packages \ curl.7.30.0.2"文件夹中大约一半的"libcurl.lib文件"后，我终于找到了一个已编译的文件.我在项目属性->链接器->常规->附加库目录"中添加了"$(SolutionDir)\ packages \ curl.7.30.0.2 \ build \ native \ lib \ v110 \ Win32 \ $(Configuration)\ dynamic"字段.

After trying about half of the "libcurl.lib files in the "packages\curl.7.30.0.2" folder, I finally found one that compiled. I added "$(SolutionDir)\packages\curl.7.30.0.2\build\native\lib\v110\Win32\$(Configuration)\dynamic" to the project "Properties->Linker->General->Additional Library Directories" field.

现在的问题是，运行它时，找不到LIBCURL.dll".这使我意识到，我早先喜欢动态版本的.lib文件.这不是我想要的.我想静态链接库，而不要麻烦DLL.

Now the problem is that when running it, "LIBCURL.dll is not found". This made realize that earlier I liked against the dynamic version of the .lib file. This is not what I want. I want to statically link the library and not bother with a DLL.

这是在实际应用中尝试运行之前的示例代码:

Here is the sample code I am trying to run before I try this in my real application:

#include "stdafx.h"
#include <iostream>
#include <stdio.h>
#include <curl/curl.h>


int main()
{
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();
    if (curl) {
        curl_easy_setopt(curl, CURLOPT_URL, "http://google.com");
        res = curl_easy_perform(curl);

        /* always cleanup */
        curl_easy_cleanup(curl);
    }
    return 0;
}

我详细研究了每个相关问题，如果我需要的答案在其中，则看不到它:

I looked in detail at each of these related questions and if the answer that I need is in there, I do not see it:

使用curl NuGet无法解析的外部符号

使用Visual Studio 2013的cURL

CURL Nuget visual函数_main()中引用的Studio 2013无法解析的外部符号__imp__curl_easy_init

添加curl库C ++

这是我第一次将Nuget与C ++项目一起使用，因此很可能我根本不了解简单的内容.

This is the first time I am using Nuget with a C++ project, so it is very possible that I simply do not understand something simple.
