如何在 HTTP GET 请求中发送原始数据？

发布于 2024-10-08 07:30:07 字数 596 浏览 2 评论 0原文

在 http://alx3apps.appspot.com/jsonrpc_example/ 的示例中，当我单击提交按钮时，我注意到（通过使用 Firebug）我的浏览器提交了源代码：

{"params":["Hello ","Python!"],"method":"concat","id":1}

它没有发布参数（例如json=[上面的编码字符串]），而只是发布具有上述值的原始字符串。

是否有一种广泛接受的方法来通过 GET 请求复制此内容，或者我是否需要对相同的字符串进行 urlencode 并将其包含为 http://www.example.com/?json=%7b%22params%22 %3a%5b%22Hello+%22%2c%22Python!%22%5d%2c%22method%22%3a%22concat%22%2c%22id%22%3a1%7d？我知道一些较旧的浏览器无法处理超过 250 个字符的 URI，但我对此表示同意。

In the example at http://alx3apps.appspot.com/jsonrpc_example/ when I click the submit button, I notice (by using Firebug) that my browser submits the source:

{"params":["Hello ","Python!"],"method":"concat","id":1}

It's not posting a parameter (eg. json=[encoded string from above]), but rather just posting a raw string with the above value.

Is there an widely accepted way to replicated this via a GET request, or do I need to just urlencode the same string and include it as http://www.example.com/?json=%7b%22params%22%3a%5b%22Hello+%22%2c%22Python!%22%5d%2c%22method%22%3a%22concat%22%2c%22id%22%3a1%7d? I understand that some older browsers cannot handle a URI of more than 250 characters, but I'm OK with that.

除了标头之外，GET 请求通常不会以任何其他方式传输数据，因此如果您希望使用 GET，则应该传递 URL 中编码的字符串。

POST http://alx3apps.appspot.com/jsonrpc_example/json_service/ HTTP/1.1
Host: alx3apps.appspot.com

{"params":["Howdy","Python!"],"method":"concat","id":1}

在普通表单中，标题 Content-Type: application/x-www-form-urlencoded 让服务器知道期望采用 key=val 格式的格式，而您链接的页面发送 Content -类型：application/json-rpc；字符集=UTF-8。在标题（以空行结束）之后是指定格式的数据。

A GET request doesn't usually transmit data in any other way besides headers, so you should pass the string encoded in the URL if you wish to use GET.

POST http://alx3apps.appspot.com/jsonrpc_example/json_service/ HTTP/1.1
Host: alx3apps.appspot.com

{"params":["Howdy","Python!"],"method":"concat","id":1}

In a normal form post the header Content-Type: application/x-www-form-urlencoded lets the server know to expect the format in key=val format whereas the page you linked sends Content-Type: application/json-rpc; charset=UTF-8. After the headers (which are terminated with the blank line) the data follows in the specified format.
