ReferenceError: openpgp is not defined

Question

我正在创建一个简单的 chrome 扩展，它可以使用 openPGP 的库加密和解密字符串。但是，我似乎无法定义 openGPG 并不断收到错误消息：

ReferenceError: openpgp is not defined

我已经在我的 HTML 文件中定义了 openGPG 库，我认为它可以在全球范围内使用，对吗？

我的HTML&JS代码如下

我加密的JS文件。非常早的版本，但只是想运行它在定义键和添加逻辑之前。

    document.getElementById("encryptTest").addEventListener('click', () => {
        console.log("Popup DOM fully loaded and parsed");
    
        async function encryptString() {
            // put keys in backtick (``) to avoid errors caused by spaces or tabs
            const publicKeyArmored = `-----BEGIN PGP PUBLIC KEY BLOCK-----
        ...
        -----END PGP PUBLIC KEY BLOCK-----`;
            const privateKeyArmored = `-----BEGIN PGP PRIVATE KEY BLOCK-----
        ...
        -----END PGP PRIVATE KEY BLOCK-----`; // encrypted private key
            const passphrase = `yourPassphrase`; // what the private key is encrypted with
        
            const { keys: [privateKey] } = await openpgp.key.readArmored(privateKeyArmored);
            await privateKey.decrypt(passphrase);
        
            const { data: encrypted } = await openpgp.encrypt({
                message: openpgp.message.fromText('Hello, World!'),                 // input as Message object
                publicKeys: (await openpgp.key.readArmored(publicKeyArmored)).keys, // for encryption
                privateKeys: [privateKey]                                           // for signing (optional)
            });
            console.log(encrypted); // '-----BEGIN PGP MESSAGE ... END PGP MESSAGE-----'
            const { data: decrypted } = await openpgp.decrypt({
                message: await openpgp.message.readArmored(encrypted),              // parse armored message
                publicKeys: (await openpgp.key.readArmored(publicKeyArmored)).keys, // for verification (optional)
                privateKeys: [privateKey]                                           // for decryption
            });
            console.log(decrypted); // 'Hello, World!'
        }
    
        //We have permission to access the activeTab, so we can call chrome.tabs.executeScript:
        chrome.tabs.executeScript({
            code: '(' + encryptString + ')();' //argument here is a string but function.toString() returns function's code
        });
    });

我认为问题在于该函数在您的代码中是孤立的。还要确保在 HTML 文件中正确定义它。欢迎来到 Stack Overflow :) !
