坑爹的curl: Required request body is missing : post 请求体 不能包含汉字!

发送curl 请求:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: text/html' -d '{ \
   "body": { \
     "account": "41557558612310085632", \
     "appid": "5000000002", \
     "amount": 12350,  \
     "paypalAccountEmail": "test%40qq.com", \
     "remark": "asd测试" \
   } \
 }' 'https://mwtest.luo.cn/pp/withdraw/toPaypal'

各种curl 请求错误

竟然出现了各种错误:

改成:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: text/html' -d '{ 
"body": { 
"account": "41557558612310085632",

"amount": 12350, 
"paypalAccountEmail": "[e-mail]", 
"remark": "asd测试" 
} 
}' 'https://mwtest.l.cn/pp/withdraw/toPaypal'

改成这样:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: application/json' -d '{"body":{"account":"41557558612310085632","appid":5000000002","amount":12350,"orderNo":"WITHDRAW2022081917180700000003"}}' 'https://mwtest.luo.cn/pp/withdraw/detail'

curl -X POST --header 'Content-Type: application/json' --header 'Accept: text/html' -d '{"body": {"account": "41557558612310085632","appid": "5000000002","amount": "12350","paypalAccountEmail": "[e-mail]","remark": "asd测试"}}' 'https://mwtest.luo.cn/pp/withdraw/toPaypal'

百思不得其解

发现还是不行:

Caused by: com.alibaba.fastjson.JSONException: not match : - ", info : pos 69, line 1, column 70{"body":{"account":"41557558612310085632","appid":5000000002","amount":12350,"orderNo":"WITHDRAW2022081917180700000003"}}

始终提示:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: text/html' -d '{"body": {"account": "41557558612310085632","appid": "5000000002","amount": 123500,"paypalAccountEmail": "[e-mail]","remark": "asd测试"}}' 'https://mwtest.luo.cn/pp/withdraw/toPaypal'

真实奇了怪了啊, 不会 我可是用了十几年的curl 老程序员的呢..  简直怀疑人生了, 

基准测试, 发现原因

后面各种减法测试/基准测试, 发现这个却是ok的:

"body": {  
 "account": "41557558612310085632",
 "appid": "5000000002",
 "amount": 5000000,
 "paypalAccountEmail": "[e-mail]", 
 "remark": "[e-mail]2222222"     
 } 
 }' 'https://mwtest.luo.cn/pp/withdraw/toPaypal'

始终不得其解:

curl -X POST --header 'Content-Type: application/json' --header 'Accept: text/html' -d  '{"body":{"remark":"as我d"}}' 'https://mwtest.luo.cn/pp/withdraw/toPaypal'

后面 只能一个个的测试, 一个个的去掉, 加上的方式, 排除, 终于发现了是 汉字的原因! ! 

后面测试发现 tab 空格也是不行的 !

为什么不能包含汉字? 

难道是这个  git bash 不支持?

另外发现  有时候新增空行( 回车键的方式), 会导致命令断开:

why ?  应该是 \n 和 \n\r 的区别
