json - 使用 JSON 参数进行 Curl GET。服务器回复为空

Question

我在使用 curl 命令时遇到问题。我想使用 JSON 参数发送请求 (GET)，并且我应该从服务器得到一些答案，但不幸的是我什么也没得到。 在最好的情况下，我从服务器得到以下答案

* Hostname was NOT found in DNS cache
*   Trying 192.168.1.101...
* Connected to 192.168.1.101 (192.168.1.101) port 80 (#0)
> GET /ckk.cgi HTTP/1.1
> User-Agent: curl/7.38.0
> Host: 192.168.1.101
> Accept: application/json
> Content-type: application/json
> Content-Length: 41
> 
* upload completely sent off: 41 out of 41 bytes
* Empty reply from server
* Connection #0 to host 192.168.1.101 left intact
curl: (52) Empty reply from server

我阅读了以下主题:

Curl GET request with json parameter How to POST JSON data with Curl from Terminal/Commandline to Test Spring REST?

所以我尝试了以下命令

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET 192.168.1.101/ckk.cgi?json={"asking1":{"001":"givnames1","_id":223}}

curl -H "Content-Type: application/json" -X GET -d '{"asking1":{"001":"givnames1","_id":223}}' http://192.168.1.101/ckk.cgi?

curl -X GET -H "application/json" -d '{"asking1":{"001":"givnames1","_id":223}}' http://192.168.1.101/ckk.cgi?

curl -v -H "Accept: application/json" -H "Content-type: application/json" -X GET -d '{"asking1":{"001":"givnames1","_id":223}}' http://192.168.1.101/ckk.cgi?

curl -i GET -H "Accept: application/json" "http://192.168.1.101/ckk.cgi??json={"asking1":{"001":"givnames1","_id":223}}"

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET -d '{"asking1":{"001":"givnames1","_id":223}}}' 

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET -d "{"asking1":{"001":"givnames1","_id":223}}" http://192.168.1.101/ckk.cgi?

curl --data "{"asking1":{"001":"givnames1","_id":223}}}" http://192.168.1.101/ckk.cgi?

curl -v  http://192.168.1.101/ckk.cgi? --header "Content-Type: application/json" -d "{"asking1":{"001":"givnames1","_id":223}}"

所有命令都不起作用......

浏览器中的工作命令只是:

192.168.1.101/ckk.cgi?json={"asking1":{"001":"givnames1","_id":223}}

编辑:

以下问题的答案

curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X GET 192.168.1.101/ckk.cgi?json={"asking1":{"001":"givnames1","_id":223}}

Answer 1

查看工作浏览器场景在网络上发送的内容将显示如下内容:

192.168.1.101/ckk.cgi?json={%22asking1%22:{%22001%22:%22givnames1%22,%22_id%22:223}}

即JSON 部分进行 URL 编码(至少部分如此)。使用 --data-urlencode 和 -G 标志可以实现相同的效果:

curl -G -v "http://192.168.1.101/ckk.cgi" --data-urlencode 'json={"asking1":{"001":"givnames1","_id":223}}'
