[英]Node.js - writeHead to set both “Location” and “Set-Cookie”
In node.js(running this in Connect.js), I am able to set ether the Location or Set-Cookie with writehead, but not both at the same time. 在node.js中(在Connect.js中运行),我可以使用writehead设置ether或者Set-Cookie,但不能同时设置两者。 Currently, the below sets the cooke but the URL does not get redirected to the new location:
目前,下面设置了cooke,但URL没有被重定向到新位置:
function foo(req, res, next) {
var url = /container-templates/;
if (url.test(req.url)) {
console.log(url.test(req.url));
console.log(req.url);
res.writeHead(302, ["Location", 'https://staging.dx.host.com' + req.url],
["Set-Cookie", "fake-token=5b49adaaf7687fa"]);
res.end();
} else { next() }
}
On a side note, I am doing this for the learning experience and do not want to use any pre-written plugins. 在旁注中,我这样做是为了学习体验,并且不想使用任何预先编写的插件。
Response#writeHead
expects the headers to be an Object not a list of array arguments. Response#writeHead
期望标头是Object而不是数组参数列表。
The Node HTTP documentation has the following signature defined: Node HTTP文档定义了以下签名:
response.writeHead(statusCode, [reasonPhrase], [headers])
If you want to pass in multiple headers your code from above should read: 如果您想传入多个标头,则上面的代码应为:
response.writeHead(302, {
Location: 'https://staging.dx.host.com' + req.url',
'Set-Cookie': 'fake-token=5b49adaaf7687fa'
});
The []
on the reasonPhrase
means its optional and infers what you've provided to the function based on the types of the arguments. reasonPhrase
上的[]
表示它是可选的,并根据参数的类型推断您为函数提供的内容。
Also, you don't need to wrap the key
part of an object in quotes unless it contains characters that are invalid for variable names (like the -
.) And a single '
will do for all strings -- there is no difference in javascript between '
and "
. 此外,您不需要将对象的
key
部分用引号括起来,除非它包含对变量名无效的字符(如-
。)并且单个'
将对所有字符串执行 - 在javascript中没有区别之间的'
和"
。
