How to PUT a json object with an array using curl
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，所以我正在尝试制定一个等效的命令行。当我检查chrome中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
1 | 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` |
我出错了
curl: (3) [globbing] nested braces not supported at pos X
号
其中x是第一个"["的字符位置。
如何放置包含数组的JSON对象？
您的命令行应该在要发送到Put中的字符串之前插入-d/--数据，并且您希望设置内容类型而不接受。
1 | 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：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | curl -H 'Content-Type: application/json' -X PUT \ -d '{"tags":["tag1","tag2"],"question":"Which band?","answers":[{"id":"a0","answer":"Answer1 <div class="suo-content">[collapse title=""]<ul><li>-1，因为Content-Type(而不是Accept)是在这种情况下应该设置的头。</li><li>对于那些想知道的人来说，[json]只是json字符串的一个占位符。不要在JSON字符串周围添加额外的方括号。</li></ul>[/collapse]</div><hr> <p> Although the original post had other issues (i.e. the missing"-d"), the error message is more generic. </p> <blockquote> <p> curl: (3) [globbing] nested braces not supported at pos X </p> </blockquote> <p> This is because curly braces {} and square brackets [] are special globbing characters in curl.

For curl the syntax is: </p> [cc]-H 'Content-Type: application/json' |

所以完整的curl命令是：
1 2 3 4 5 6 7 8 9 10 11 | curl -H 'Content-Type: application/json' -H 'Accept: application/json' -X PUT -d '{"tags":["tag1","tag2"],"question":"Which band?","answers":[{"id":"a0","answer":"Answer1 <hr> <p> Try using a single quote instead of double quotes along with -g </p> <p> Following scenario worked for me </p> [cc]curl -g -d '{"collection":[{"NumberOfParcels":1,"Weight":1,"Length":1,"Width":1,"Height":1}]}" -H"Accept: application/json" -H"Content-Type: application/json" --user [email protected]:123456 -X POST https://yoururl.com |
用
1 | curl -g -d"{'collection':[{'NumberOfParcels':1,'Weight':1,'Length':1,'Width':1,'Height':1}]}" -H"Accept: application/json" -H"Content-Type: application/json" --user [email protected]:123456 -X POST https://yoururl.com |
。
这特别解决了我的错误curl命令错误：错误的url冒号是第一个字符
The only thing that helped is to use a file of JSON instead of json body text. Based on How to send file contents as body entity using cURL
