在Node.js JavaScript中向用户发送消息的gmail API失败 [英] gmail API for sending users messages in nodejs javascript failes
问题描述
我的nodejs程序无法使用Gmail api发送邮件.
My nodejs program fails to send messages using the Gmail api.
来自 Gmail API的解决方案，用于在Node.js中发送邮件对我不起作用.
我使用
var {google} = require('googleapis');
// to and from = "some name <blaw.blaw.com"
function makeBody(to, from, subject, message) {
var str = ["Content-Type: text/plain; charset=\"UTF-8\"\r\n",
"MIME-Version: 1.0\r\n",
"Content-Transfer-Encoding: 7bit\r\n",
"to: ", to, "\r\n",
"from: ", from, "\r\n",
"subject: ", subject, "\r\n\r\n",
message
].join('');
encodedMail = new Buffer(str).toString("base64").replace(/\+/g, '-').replace(/\//g, '_');
return encodedMail;
}
然后转到Google API资源管理器 https://developers.google.com/apis-explorer/#p/ 输入gmail.users.messages.send以及从上面的make_body生成的字符串.
Then go to the Google API explorer https://developers.google.com/apis-explorer/#p/ enter gmail.users.messages.send and the string generated from the above make_body.
电子邮件将成功发送.所以我知道上面的编码是 好吧.
An email will be successfully sent. So I know the above encoding is ok.
当我的程序尝试使用以下命令发送时，它失败并显示错误
When my program tried to send using the following, it fails with error
错误:原始" RFC822有效负载消息字符串或通过以下方式上载消息 /upload/*需要网址
Error: 'raw' RFC822 payload message string or uploading message via /upload/* URL required
function sendMessage(auth) {
var gmail = google.gmail('v1');
var raw = makeBody('john g <asdfasdf@hotmail.com>', 'john g<asfasdgf@gmail.com>', 'test subject', 'test message #2');
gmail.users.messages.send({
auth: auth,
userId: 'me',
resource: {
raw: raw
}
}, function(err, response) {
console.log(err || response)
});
}
身份验证令牌很好，因为我可以调用gmail.users.labels.list，并且在使用API资源管理器时使用相同的授权.
The auth token is good since I can call gmail.users.labels.list and I use the same authorization when using the API explorer.
问题1:有谁知道为什么上述方法不起作用?
Q1: Does anyone know why the above does not work?
第二季度:用于发送的Gmail API Node.js中的邮件没有解释为什么将原始电子邮件包装在资源字段中.我只是尝试原始的，但并没有帮助.
Q2: Gmail API for sending mails in Node.js does not explain why the raw email message is wrapped inside a resource field. I tried simply raw and it did not help.
这失败.
gmail.users.messages.send({
auth: auth,
userId: 'me',
resource: {
raw: raw
}
}, function(err, response) {
console.log(err || response)
});
gmail.users.messages.send({
auth: auth,
userId: 'me',
raw: raw
}, function(err, response) {
console.log(err || response)
});
gmail.users.messages.send({
auth: auth,
userId: 'me',
data: raw
}, function(err, response) {
console.log(err || response)
});
有人知道它在哪里记录了如何通过api资源管理器所要求的请求的主体"吗?
Does anyone know where its documented how to pass the "requested body" the api explorer is asking for?
第三季度:为什么Google API需要在base64编码中进行替换?
Q3: Why does the google api need substitutions in the base64 encoding?
我尝试使用
const Base64 = require("js-base64").Base64
var encodedMail = Base64.encode(str);
当我将其输入到API资源管理器中时，我得到了错误
When I feed this into the API explorer, I get the error
"message":"ByteString的值无效:
"message": "Invalid value for ByteString:
推荐答案
Ohai！对于在这里绊倒的其他人，有几件事.首先-我们现在有一个完整的端到端发送邮件示例:
Ohai! For others that stumble here, a few things. First - we have a complete end to end sample of sending mail now here:

第二，上面的答案基本上是正确的:)而不是安装最新版本的google-auth-library ...只需将其从package.json中全部删除即可.入门指南非常非常错误(此问题已得到修复). googelapis引入了它自己的兼容版本google-auth-library，因此您真的不想通过安装自己的版本来弄混它:)
Second, the answer above is mostly right :) Instead of installing the latest version of google-auth-library... just remove it from your package.json all together. The getting started guide was very, very wrong (it has since been fixed). googelapis brings in it's own compatible version of google-auth-library, so you really don't want to mess with that by installing your own version :)
