来自javascript的HTTP请求使用包括标头的原始消息 [英] HTTP request from javascript using raw message including headers
问题描述
我知道如何使用jQuery或XMLHttpRequest从javascript向我的REST api发出HTTP请求。我现在要做的是在不设置标题值属性的情况下发出请求。 HTTP请求消息包含：
I know how to make an HTTP request to my REST api from javascript using jQuery or XMLHttpRequest. What I want to do now is make the request without setting properties for the header values. An HTTP request message consists of:
- 请求行，例如GET /images/logo.png HTTP / 1.1，它从服务器请求名为/images/logo.png的资源
- 标题，例如Accept-Language：zh
- 空行
- 可选消息正文
- Request line, such as GET /images/logo.png HTTP/1.1, which requests a resource called /images/logo.png from server
- Headers, such as Accept-Language: en
- An empty line
- An optional message body
对我的api的请求应如下所示：
A request to my api should look something like this:
GET /myapi/myresource/1234 HTTP/1.1
Host: localhost:51127
Content-Type: application/x-www-form-urlencoded
Accept: application/json, text/csv
Authorization: Basic <base64 encoded credentials>
我想打开一个到localhost的连接：51127，发送上面的文字，并得到回复。这可以在javascript中使用吗？
I would like to open a connection to localhost:51127, send the above text, and get the response. Is this possible in javascript?
更新：我知道如何设置标题。我只想以不同的方式做到这一点。
有很多方法可以构建
请求，包括标题并发送它。
我只是想手动构建它。
Update: I know how to set headers. I just want to do it a different way. There are lots of ways to "build" a request including headers and send it. I just want to build it manually.
推荐答案
没有套接字支持在Javascript中。您只能使用 XMLHTTPRequest 包装器或 的包装器来构建HTTP查询，例如 jQuery.ajax 。这是出于各种好的理由，主要是安全性。
There is no socket support in Javascript. You can only build HTTP queries by using the XMLHTTPRequest wrapper, or optionally wrappers for that such as jQuery.ajax. This is for all kinds of good reasons, principally security.
