在Apps脚本中处理POST请求后重定向 [英] Redirect after processing a POST request in Apps Script
问题描述
我在让Google脚本页面重定向回我的自定义URL时遇到问题。该脚本当前正在执行，但执行完毕后无法将其重定向回其上一页。
I have had an issue with getting the google scripts page to redirect back towards my custom URL. The script currently executes but I cant get it to redirect back to its previous page after it is finished executing.
此处是script.gs代码：
Heres the script.gs code:
function doPost(e) {
try {
Logger.log(e); // the Google Script version of console.log see: Class Logger
record_data(e);
// shorter name for form data
var mailData = e.parameters;
var name= String(mailData.name);
var message= String(mailData.message);
var email= String(mailData.email);
var all= ("Name: "+name+"\nReply address: "+email+"\nMessage: "+message);
// determine recepient of the email
// if you have your email uncommented above, it uses that `TO_ADDRESS`
// otherwise, it defaults to the email provided by the form's data attribute
var sendEmailTo = (typeof TO_ADDRESS !== "undefined") ? TO_ADDRESS : mailData.formGoogleSendEmail;
MailApp.sendEmail({
to: String(sendEmailTo),
subject: String(mailData.subject),
replyTo: String(mailData.email), // This is optional and reliant on your form actually collecting a field named `email`
body: String(all)
});
doGet();
return HtmlService.createHtmlOutput('xxxxxxxxxx.com');
} catch(error) { // if error return this
Logger.log(error);
return ContentService
.createTextOutput(JSON.stringify({"result":"error", "error": error}))
.setMimeType(ContentService.MimeType.JSON);
}
}
function doGet() {
return HtmlService.createHtmlOutputFromFile('Index');
}
这是我的HTML代码：
Here is my HTML code:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="refresh" content="2;url=xxxxxxxxxx.com" />
<base target="_top">
</head>
<body>
Click <a href="xxxxxxxxxx.com">here</a> to go back.
</body>
</html>
使脚本打开index.html页面的最佳方法是什么，这样我可以轻松地重定向回到自定义网址？
What would be the best way to make the script open the index.html page so I could easily redirect back to the custom URL?
推荐答案
这是处理POST请求后重定向的有效示例。
Here's a working example of redirecting after processing a POST request.
var REDIRECT_URL = "http://www.stackoverflow.com";
function doPost(e) {
Logger.log("POST request");
Logger.log(e)
return redirect();
}
function doGet() {
Logger.log("GET request");
var template = HtmlService.createTemplateFromFile("form");
template.url = ScriptApp.getService().getUrl();
return template.evaluate();
}
function redirect() {
return HtmlService.createHtmlOutput(
"<script>window.top.location.href=\"" + REDIRECT_URL + "\";</script>"
);
}
form.html
form.html
<!DOCTYPE html>
<html>
<head>
<base target="_top">
</head>
<body>
<form action="<?= url ?>" method="post">
<input type="text" name="test_field" value="test data">
<button type="submit">Submit form</button>
</form>
</body>
</html>
用法
当我访问发布的Web应用程序（即使用GET请求），将显示简单的表单。
Usage
When I visit the published web app (i.e. using a GET request), I'm presented with the simple form.
提交该表格（即使用POST请求）后，我立即被重定向到 http://www.stackoverflow.com 。
Submitting that form (i.e. using a POST request), I'm immediately redirected to http://www.stackoverflow.com.
此输出在脚本日志中捕获：
This output is captured in the script log:
[18-06-19 10:39:04:731 PDT] POST request
[18-06-19 10:39:04:732 PDT] {parameter={test_field=test data}, contextPath=, contentLength=20, queryString=, parameters={test_field=[test data]}, postData=FileUpload}
关于代码示例，您具有：
Regarding your code sample, you have:
doGet();
return HtmlService.createHtmlOutput('xxxxxxxxxx.com');
这没有意义，因为您对<$ c $的结果不做任何事情c> doGet（）。为了使 doGet（）调用有用，将上面的内容替换为以下内容：
That doesn't make sense as you're not doing anything with the results of doGet(). In order to make the doGet() call useful, replace the above with the following:
return doGet();
