curl -GET 和 -X GET [英] curl -GET and -X GET

问题描述

Curl 提供了一系列不同的以 X 为前缀的 http 方法调用，但也提供了相同的方法.我都试过，我似乎无法弄清楚区别.有人可以快速向我解释这两种操作有何不同吗?

Curl offers a series of different http method calls that are prefixed with a X, but also offers the same methods without. I've tried both and I can't seem to figure out the difference. Can someone explain to me quickly how these two operations differ?

推荐答案

默认情况下，您使用 curl 而不明确说明要使用哪种请求方法.如果你只是传入一个像 curl http://example.com 这样的 HTTP URL，它将使用 GET.如果您使用 -d 或 -F curl 将使用 POST，-I 将导致 HEAD 和 -T将使其成为 PUT.

By default you use curl without explicitly saying which request method to use. If you just pass in a HTTP URL like curl http://example.com it will use GET. If you use -d or -F curl will use POST, -I will cause a HEAD and -T will make it a PUT.

如果出于某种原因您对 curl 为您所做的这些默认选择不满意，您可以通过指定 -X [WHATEVER] 来覆盖这些请求方法.通过这种方式，您可以例如通过执行 curl -X DELETE [URL] 发送 DELETE.

If for whatever reason you're not happy with these default choices that curl does for you, you can override those request methods by specifying -X [WHATEVER]. This way you can for example send a DELETE by doing curl -X DELETE [URL].

因此执行 curl -X GET [URL] 毫无意义，因为无论如何都会使用 GET.同样，执行 curl -X POST -d data [URL]... 但是您可以创建一个有趣且有点罕见的请求，该请求在 GET 请求中发送请求正文类似于 curl -X GET -d data [URL].

It is thus pointless to do curl -X GET [URL] as GET would be used anyway. In the same vein it is pointless to do curl -X POST -d data [URL]... But you can make a fun and somewhat rare request that sends a request-body in a GET request with something like curl -X GET -d data [URL].

curl -GET(使用单个破折号)对于此目的是错误的.这相当于指定 -G, -E 和 -T 选项，这将做一些完全不同的事情.

curl -GET (using a single dash) is just wrong for this purpose. That's the equivalent of specifying the -G, -E and -T options and that will do something completely different.

还有一个名为 --get 不要将问题与两者混淆.是-G的长格式，用于转换-d指定的数据 变成 GET 请求而不是 POST.

There's also a curl option called --get to not confuse matters with either. It is the long form of -G, which is used to convert data specified with -d into a GET request instead of a POST.

(我随后在此处使用了我自己的答案来填充 curl 常见问题解答以涵盖此内容.)

(I subsequently used my own answer here to populate the curl FAQ to cover this.)

当启用详细模式 (-v) 时，curl 的现代版本将通知用户这种不必要且可能有害的 -X 使用 - 让用户意识到.这篇博文.

Modern versions of curl will inform users about this unnecessary and potentially harmful use of -X when verbose mode is enabled (-v) - to make users aware. Further explained and motivated in this blog post.

您可以要求 curl 转换一组 -d 选项，而不是使用 POST 在请求正文中发送它们，而是将它们放在 URL 查询字符串的末尾并发出 GET，使用使用`-G.像这样:

You can ask curl to convert a set of -d options and instead of sending them in the request body with POST, put them at the end of the URL's query string and issue a GET, with the use of `-G. Like this:

curl -d name=daniel -d grumpy=yes -G https://example.com/
