如何使用 curl 放置一个带有数组的 json 对象 [英] How to PUT a json object with an array using curl

问题描述

我有一系列数据要输入数据库.输入数据的用户界面不适合批量输入，所以我试图制定一个等效的命令行.当我在 chrome 中检查 UI 的网络请求时，我看到一个 json 对象的 PUT 请求.当我尝试复制请求时

I have a series of data to enter into database. The user interface to enter the data isn't good for bulk entry, so I'm trying to formulate a command line equivalent. When I examine the network request of the UI in chrome, I see a PUT request of a json object. When I try to replicate the request

curl -H 'Accept: application/json' -X PUT '{"tags":["tag1","tag2"],"question":"Which band?","answers":[{"id":"a0","answer":"Answer1"},{"id":"a1","answer":"answer2"}]}' http://example.com/service`

我收到一个错误

curl: (3) [globbing] pos X 不支持嵌套大括号

curl: (3) [globbing] nested braces not supported at pos X

其中X是第一个["的字符位置.

Where X is the character position of first "[".

如何放置包含数组的 json 对象?

推荐答案

你的命令行应该有一个 -d/--data 插入到要在 PUT 中发送的字符串之前，并且要设置 Content-Type 而不是 Accept.

Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.

curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' 
     http://example.com/service

使用问题中的确切 JSON 数据，完整的命令行将变为:

Using the exact JSON data from the question, the full command line would become:

curl -H 'Content-Type: application/json' -X PUT 
    -d '{"tags":["tag1","tag2"],
         "question":"Which band?",
         "answers":[{"id":"a0","answer":"Answer1"},
                    {"id":"a1","answer":"answer2"}]}' 
    http://example.com/service

注意:JSON 数据仅用于可读性包装，对于 curl 请求无效.

Note: JSON data wrapped only for readability, not valid for curl request.
