aws-sdk如何加载配置

有一点神奇之处

设置env变量

C:\Users\Kevin>python

ImportError: DLL load failed: The specified procedure could not be found.

During handling of the above exception, another exception occurred:

    raise ImportError(msg)
ImportError:
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes all
files not under version control).  Otherwise reinstall numpy.

Original error was: DLL load failed: The specified procedure could not be 
found.

或在加载aws-sdk set之前

export AWS_SDK_LOAD_CONFIG="true"

然后加载aws模块;

process.env.AWS_SDK_LOAD_CONFIG = true;

您可以通过

直接访问该地区

var AWS = require('aws-sdk');

Answer 2

有这方面的文件：

我建议安装awscli工具进行设置，然后在终端中运行aws configure。默认情况下，您在本地主机上运行的任何内容都将采用config文件中列出的凭据，除非指定采用其他配置文件。

来自第一个链接的示例：

AWS.config.credentials = new AWS.SharedIniFileCredentials( { profile: 'work-account' } );

如果您使用CLI运行脚本：

AWS_PROFILE=work-account node script.js

如果您只使用CLI工具而不使用JavaScript：

aws s3 ls --profile work-account

<强>更新

config和credentials在同时 制作并引用。当您运行aws configure时，它会生成两个文件。包含AccessKey和SecretKey的credentials文件 - 以及包含响应类型和区域的config文件。没有必要明确定义或引用config文件。

Answer 3

The answer of sreenivas是正确的。这似乎也是不编写自定义函数即可做到这一点的唯一方法。

我已经在source code中找到了它，并且它加载~/.aws/config的方式与此伪代码类似：

if process.env.AWS_SDK_LOAD_CONFIG:
  return load('~/.aws/credentials').overwrite('~/.aws/config')
else:
  return load('~/.aws/credentials')

这也意味着您可以在require('aws-sdk')之后设置环境变量，只要您在new SharedIniFileCredentials({..})或credentials.refresh()之前设置即可。请注意，credentials.get()在会话令牌过期之前将无法工作。
