有没有办法将http代理用于google-cloud-cpp? [英] Is there a way to use an http proxy for google-cloud-cpp?

问题描述

我正在使用 google-cloud-cpp (适用于Google Cloud Platform的C ++ API函数)来创建/读取/写入存储桶.当我在组织的防火墙内工作时，我必须使用代理才能连接到Google Cloud. 我看到我们可以使用gcloud命令行配置代理: gcloud config设置代理/类型http gcloud配置设置代理/地址x.x.x.x gcloud config设置代理/端口

I am using google-cloud-cpp (C++ API for Google Cloud Platform functions) to create/read/write to buckets. When I am working from within the organization's firewall, I have to use a proxy to be able to connect to google cloud. I see that we can configure a proxy using the gcloud command line: gcloud config set proxy/type http gcloud config set proxy/address x.x.x.x gcloud config set proxy/port

使用google-cloud-cpp时可以做类似的事情吗?

Can I do something similar when I use google-cloud-cpp?

推荐答案

如果我们查看GitHub上的google-cloud-cpp库的源代码，我们似乎会发现它基于libcurl.

If we look at the source code of the google-cloud-cpp library as found on GitHub, we seem to see that it is based on libcurl.

请参阅: https://github.com/googleapis/google-cloud-cpp/blob/master/google/cloud/storage/internal/curl_handle.cc

接下来，根据@Travis Webb的评论，我们查看libcurl的文档并找到:

Following on from the comments by @Travis Webb, we then look at the docs for libcurl and find:

https://curl.haxx.se/libcurl/c/CURLOPT_PROXY.html

此文档介绍了可用于为使用libcurl的程序设置代理设置的API.但是，如果我们读得更深入，则会发现有关环境变量的部分，该部分声明可以设置http_proxy和https_proxy.

This documents API that can be used to set proxy settings for programs that use libcurl. However, if we read deeper, we find a section on environment variables that declares that http_proxy and https_proxy can be set.
