Curl --- the request fails when the post request parameter is too long (more than 1024b)

Today I send curl when , Report errors Argument list too long

curl -H “Content-Type: application/json " -iv -X POST -d '{“id”:“1111112012”,“name”:”…",“age”:"…"}’ http://192.168.1.1:3000/api/query
（… A lot of things have been omitted ）

So it was changed to json Put the parameters in param.json File

curl -H "Content-Type: application/json " -iv -X POST -d @‘param.json’ http://192.168.1.1:3000/api/query

But back 100-continue
 
 
reason ：
because post The request header of the request defaults to “Expect”:“100-continue”, That is, sending more than 1024B After parameter of size , You will first ask the server whether it receives , The server will not continue sending until it agrees to accept .
 
 
terms of settlement ：
Modify request header Expect The parameter is empty. ,-H “Expect”:" "

curl -H “Expect”:" " -H "Content-Type: application/json " -iv -X POST -d @‘param.json’ http://192.168.1.1:3000/api/query
