Question

我遇到curl命令的问题。我想发送请求（GET）与JSON参数，我应该从服务器得到一些答案但不幸的是我没有得到。在最好的情况下，我得到答案表单服务器

* Hostname was NOT found in DNS cache

我阅读以下主题：

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Works命令只是：

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

修改

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

通过工作浏览器方案查看在线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部分获得URL编码（至少部分）。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}}'

Curl GET与JSON参数。来自服务器的空回复
