我们尝试使用 Node.js（和 Mocha）作为测试框架来测试通过 https 的内部服务器的 API 调用。 我们使用以下节点模块：Mocha、Restify 和 Should 来执行这些测试。
当我们运行 mocha testFileName.js 时，我们得到的主要错误是：
[2013-06-19 14:16:28.105] [ERROR] console - FAIL: Received error! [Error: UNABLE_TO_VERIFY_LEAF_SIGNATURE]

搜索 google 和 stackexchange 后，我们似乎遇到了证书问题。从那里我们安装了内部 CA“公共”证书，以及我们的应用程序正在使用的实例特定认证（有多个重定向需要通过），以
/usr/local/etc/openssl/certs, legacy: /System/Library/Keychains/X509Anchors, /Library/Keychains/System.keychain, as well as in Keychain through the gui to our login and System keychains. However, we're still not getting anywhere.
在这些地方安装证书之前，我们无法在命令行上没有证书错误的情况下“卷曲”我们的网站；然而，现在安装它们后，我们没有收到任何错误，但节点仍然爆炸。
我们尝试了多个版本的 Node、OpenSSL 以及不同的安装方法，包括下载软件包与使用自制软件。
计算机信息：
Node.js 是否使用自己的（捆绑的）版本的 OpenSSL，而不是本地计算机上安装的版本？ 如果是这样的话，去哪里找证书呢？ TLS.js 是否可以告诉 Node 在其他地方寻找证书？ 是否有一种实用的方法来覆盖所使用的证书？看来我们可能可以使用这样的选项：
var options = {
ca: fs.readFileSync("[path to our CA cert file]"),
requestCert: true,
rejectUnauthorized: true
};
var req = https.request(options, function(res) {
...
});
但这会产生同样的错误。
无法验证_LEAF_SIGNATURE
问题是您正在尝试从存储库安装带有错误或不受信任的
SSL要解决此问题，您可以运行以下命令：
npm config set strict-ssl false
作为最佳实践，明智的做法是将其设置回真实的后记，这样您就不会意外安装您实际上不信任的不受信任的模块。
回答有关使用 OpenSSL 捆绑版本的第一个问题：
node 在编译期间根据加密 api 的需要生成静态对象。
例如，加密 API 需要以下 OpenSSL 函数调用：

因此，当编译节点时，它会创建一个静态对象，其中仅包含它需要的函数。这是核心 Node.js 团队的设计决策，可以最大限度地减少膨胀。
如果您希望将节点链接到 OpenSSL 的行为从静态更改为共享，您可以从源代码编译node.js，如下所示：
$ curl -k http://nodejs.org/dist/v0.10.26/node-v0.10.26.tar.gz | zcat | tar -xf -; cd node-v0.10.26; ./configure --shared-openssl
回答第二个问题：
TLS 模块使用您指定的证书。您可以使用 OpenSSL 测试服务器的功能及其相应的证书，如下所示：
openssl s_client -connect server:port
这将为您提供有关证书链的详细信息，而使用诸如curl等工具无法轻松获得这些详细信息。
简单的修复方法应该是将此选项设置为 false，因为您的测试客户端未配置为发送任何客户端证书。
var options = {
/* ... */
rejectUnauthorized: false
/* ... */
}
就“实际问题”而言，它源于客户端证书存储、其受信任的 CA 源（浏览器 SSL 证书管理器）以及服务器证书及其 CA 不被客户端信任的组合。
希望能澄清。
尝试类似：
cas = [fs.readFileSync("[path to our CA cert file]"],
https.globalAgent.options.ca = cas;
摘自http://permalink.gmane.org/gmane.comp.mozilla.identity.devel/3762
它对我有用，而所有其他解决方案都失败了，似乎这需要应用于全局代理。
有时，如果您使用具有某些代理配置的网络，npm 无法验证包签名。
试试这个，
npm set strict-ssl false
取自https://github.com/Leaflet/Leaflet/issues/2860
之后，
npm cache clean --force
它会起作用的。我试过这个。
要解决此问题，请使用
安装模块
node_extra_ca_certs_mozilla_bundle
npm install --save node_extra_ca_certs_mozilla_bundle
然后在代码中使用它：
const fs = require('fs');
const https = require('https');
https.globalAgent.options.ca = yourCertificatePEMcontent + fs.readFileSync('node_modules/node_extra_ca_certs_mozilla_bundle/ca_bundle/ca_intermediate_root_bundle.pem');
这个方法对我有用。
您可以尝试在运行命令时添加
--insecure我通过 https 解决了与我其余部分相同的问题。当我连接节点客户端时，我收到这些错误。我的解决方案是使用中间证书。
var key_content = fs.readFileSync('./resources/certificates/foo/foo.es_private_key.key');
var cert_content = fs.readFileSync('./resources/certificates/foo/foo.es_ssl_certificate.crt');
var ca_content = fs.readFileSync('./resources/certificates/foo/_.foo.es_ssl_certificate_INTERMEDIATE.crt');
var options = {
key: key_content,
cert: cert_content,
ca: ca_content
};
var server = https.createServer(options, app);
我已经在我的 Linux (Docker) 环境和 Node v22.11 中通过设置环境变量解决了这个错误：
NODE_EXTRA_CA_CERTS=/etc/ssl/certs/ca-certificates.crt/etc/ssl/certs/ca-certificates.crt
