电子邮件NodeJS无法发送 [英] Email NodeJS cannot send

问题描述

我想从NodeJs发送电子邮件.我在npmjs.org上进行了快速搜索，发现了2个有前途的库:

I want to send an email from NodeJs. I did a quick search on npmjs.org and found 2 promising libraries:

Nodemailer

和

电子邮件js

首先，我按照说明安装和运行NodeMailer，但是它不起作用.我想从Gmail发送电子邮件，因此，我启用了安全性较低" 应用以及已启用验证码."https://nodemailer.com/usage/using-gmail/" rel ="nofollow noreferrer"> Nodemailer .但是，即使我这样做了，也无法使它起作用.

First, I followed the instructions to install and run NodeMailer, but It does not work. I wanted to send email from Gmail, thus, I enabled the "less secured" apps and also enabled captcha as suggested in the documentation of Nodemailer. However, even though I did this I could not make it work.

此外，我尝试切换到大学的电子邮件，因此找到了它的SMTP服务器和端口并配置了设置.该错误仍然存​​在，主要是:

In addition, I tried to switch to my University's email, so I found its SMTP server and Port and configured the settings. The error persisted, mainly:

(node:825) UnhandledPromiseRejectionWarning: Unhandled promise rejection
(rejection id: 1): Error: connect EAGAIN 134.91.56.35:587 - Local (0.0.0.0:58442)
(node:825) [DEP0018] DeprecationWarning: Unhandled promise rejections are 
deprecated. In the future, promise rejections that are not handled will 
terminate the Node.js process with a non-zero exit code.

我不确定如何解决它，因此我尝试了下一个客户端EmailJs.那里的错误是:

I am not exactly sure how to fix it, so I tried the next client, EmailJs. The error there is:

{ Error: connection encountered an error (connect EAGAIN 134.91.56.35:587 ...
code: 5,
previous: ...
... smtp: undefied}

我可以清楚地看到，上面写着smtp是未定义的，但是我已经证实它是相同的.

I can clearly see that it is written that smtp is undefined, but I have verified that it is the same.

为了澄清，我在Windows的Bash上运行NodeJ，但是由于我知道它存在一些问题，因此我也在Raspberry PI 3上运行了代码.

To clarify, I am running NodeJs on Bash on Windows, but since I know there are some issues with it I also run the code on a Raspberry PI 3.

谢谢！

推荐答案

我设法对其进行了配置.

I managed to configure it.

根据建议，我使用了 Gmail节点.为此，您必须执行一些步骤:

As suggested I used Gmail-node. To do this you have to follow some steps:

• 首先，使用 npm install gmail-node
安装它
• 打开链接 https://console.developers.google.com/flows/enableapi?apiid = gmail
• 使用此向导在Google Developers中创建或选择一个项目控制台并自动打开API.
• 单击继续，然后转到凭据.
• 在页面顶部，选择OAuth同意屏幕标签.选择一个电子邮件地址，如果尚未输入产品名称，请输入设置，然后单击保存"按钮.
• 选择凭据"选项卡，然后单击创建凭据按钮，然后选择OAuth客户端ID.
• 选择应用程序类型其他"，输入任意名称"gmail-node-app"，然后单击创建按钮.
• 单击确定"关闭出现的对话框.
• 点击文件右侧的file_download(下载JSON)按钮客户编号.
• 将此文件移动到您的工作目录中，并与任何名称，例如client_secret.json.

现在您的程序将如下所示，您必须根据刚刚下载的文件来更改信息:

Now your program would look like this where you have to change the information in accordance to the file you just downloaded:

var gmailNode = require('gmail-node');
var clientSecret = {
    installed: {
        client_id: "k677725446467-6li25pcqgkcllsoh6f6dijcvse64n9pf.apps.googleusercontent.com",
        project_id: "clean-node-129606",
        auth_uri: "https://accounts.google.com/o/oauth2/auth",
        token_uri: "https://accounts.google.com/o/oauth2/token",
        auth_provider_x509_cert_url: "https://www.googleapis.com/oauth2/v1/certs",
        client_secret: "kF7DvoA_ZrNfa65GnU2zQBgw7",
        redirect_uris: [
            "urn:ietf:wg:oauth:2.0:oob",
            "http://localhost"
        ]
    }
};
gmailNode.init(clientSecret, './token.json', function(err,data){ ... });

但是，从网站上获取此信息后，我仍然遇到一个未知的问题，即错误:未设置访问或刷新令牌..

However, after taking this from the website, I still had an unknown problem, namely Error: No access or refresh token is set..

为了解决该问题，您需要通过记录以下代码来生成带有"TokenURL"的网址:

In order to solve it, you need to generate url with a "TokenURL" by log this code:

console.log(gmailNode.generateUrl(clientSecret));

跟随生成的URL，然后在其中复制"TokenURL".

Follow the generated URL and copy the "TokenURL" there.

最后，通过以下方式发送电子邮件:

Lastly, send an email with:

gmailNode.generateToken(clientSecret, tokenURL, (err, data) => {
        gmailNode.sendWithToken(emailMessage, clientSecret, data, function(err,data) {
                console.log(err, data)
        })
})

您完成了！

请注意，我们不再需要 init .
