EDIT: Solved, typo. Smart me \ + " " does work (backslash and space do work)
I know this has been asked before and I want to reference this post, where the - to me correct response - is using backslash.
Unfortunately, I do not know how. I tried a multiline curl request, and the following two examples made me post here, coz none of them worked:
Take 1:
curl -X PUT localhost:8080/employees/4\
-H 'Content-type:application/json'\
-d '{"name:" "Smurf", "role": "Blueman"}'
{"timestamp":"2019-01-08T13:06:36.563+0000","status":400,"error":"Bad Request","message":"Required request body is missing: payroll.Employee payroll.EmployeeController.replaceEmployee(payroll.Employee,java.lang.Long)","path":"/employees/4-H"}curl: (3) Port number ended with 'a'
[1/2]: "name:" "Smurf" --> <stdout>
--_curl_--"name:" "Smurf"
curl: (3) Port number ended with '"'
[2/2]: "role": "Blueman" --> <stdout>
--_curl_-- "role": "Blueman"
curl: (3) Port number ended with ' '
So I figured, adding space before using the backslash would solve this.
But then this happened:
curl -X PUT localhost:8080/employees/4 \
-H 'Content-type:application/json' \
-d '{"name:" "Smurf", "role": "Blueman"}'
{"timestamp":"2019-01-08T13:07:32.204+0000","status":400,"error":"Bad Request","message":"JSON parse error: Unexpected character ('\"' (code 34)): was expecting a colon to separate field name and value; nested exception is com.fasterxml.jackson.core.JsonParseException: Unexpected character ('\"' (code 34)): was expecting a colon to separate field name and value\n at [Source: (PushbackInputStream); line: 1, column: 11]","path":"/employees/4"}%
so now it doesn't accept \ as the newline terminal syntax, but tries to interept it.
What am I missing?
You have a typo. Try with:
curl -X PUT localhost:8080/employees/4 \
-H 'Content-type:application/json' \
-d '{"name": "Smurf", "role": "Blueman"}'
The error message tells you exactly which is the problem.

I want to run a bat file that checks the output of curl request and when the condition is met act accordingly.
the curl request in a bat file is as follows:
curl --insecure -X POST https://api.zilliqa.com/ -H "Content-type: application/json" --data "{\"id\":\"1\", \"jsonrpc\":\"2.0\", \"method\":\"GetNumTxBlocks\", \"params\":"[""]"}"
the output of the request is as follows: {"id":"1","jsonrpc":"2.0","result":"5820"}
and the the result is numeric, growing all the time.
As complete newbie i can not figure out how to proceed.
please give me advice, best if you could provide with example as well.
I want the IF statement to react when the last two digits of the result are greater than 95. is that also doable? for now the result is 4 digit number but will grow and be 5 then 6 digit number.
hope it is possible. if not, please suggest a possible solution.
AS curl.exe returns a json string like {"id":"1","jsonrpc":"2.0","result":"5965"}
You can parse with a for /f:
#Echo off
for /f "usebackq tokens=4 delims=:}" %%A in (`
curl --insecure -X POST https://api.zilliqa.com/ -H "Content-type: application/json" --data "{\"id\":\"1\", \"jsonrpc\":\"2.0\", \"method\":\"GetNumTxBlocks\", \"params\":"[""]"}"
`) do set "result=%%~A"
Echo result=%result%
To calculate the last two digits do a modulus division by 100 and compare with an if
Set /A "Last2Digits=result %% 100"
if %Last2Digits% gtr 95 (Echo greater 95) else ( echo less or equal 95)
Or do it in PowerShell:
$result = (curl.exe --% --insecure -X POST https://api.zilliqa.com/ -H "Content-type: application/json" --data "{\"id\":\"1\", \"jsonrpc\":\"2.0\", \"method\":\"GetNumTxBlocks\", \"params\":"[""]"}"|ConvertFrom-json).result

This is general problem of Windows users. You can use Sense Chrome Plugin or Kibana Dev Tools instead.
curl -XPUT -u elastic localhost:9200/_xpack/security/user/elastic/_password -H "Content-Type: application/json" -d "{\"password\" : \"elasticpassword\"}"

Setup
I'm Using curl in the following bash script to push a JSON file to a REST API running in tomcat sitting behind nginx.
while IFS= read -d '' -r file; do
base=$(basename "$file")
datetime=$(find $file -maxdepth 0 -printf "%TY/%Tm/%Td %TH:%TM:%.2TS")
curl -vX POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" \
-d #"$file" -u vangeeij:eian12 \
"http://192.168.105.10/homeaccess/services/aCStats/uploadData?username=vangeeij&filename=$base&datetime=$datetime"
#sudo mv "$file" /home/vangeeij/acserver/resultsOld
done < <(sudo find . -type f -print0)
Problem
When running this script I get a http 400 response with curl error:
curl: (18) transfer closed with outstanding read data remaining
What I have tried
I have found 2 things. First running the same URL and body through Postman yields a successful POST.
I found that this error goes away when the last parameter is removed from the URL &datetime=$datetime
I have also found a few connections between this error and setting a curl option something like
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Expect:'));
But I'm not sure where/how to set this exactly when using curl in a simple bash script
Question
What do I need to change in my curl command to get rid of the error and still be able to use all parameters?
UPDATE
Starting a new question, as further investigation has lead me to a better understanding of the problem.
New Question Link
The error has to do with the fact that the parameter datetime= ends up with text in it that needs to be URL encoded.
This was confirmed by replacing the variable with 2017%2F03%2F01%2008%3A50%3A56
and it worked.
So now the problem is, that I can't get --data-urlencode datetime=$datetime to work. It seems this just gets appended to the JSON data or something.
This error is being generated by the fact that the datetime= paramater is being passed in with non encoded non URL friendly characters... (eg. space).
The fix to this would be to find a way to convert the $datetime to a URLEncoded String.
eg. convert:
2017/03/01 08:50:56
TO
2017%2F03%2F01%2008%3A50%3A56
See the following discussion for one method to accomplish this.
Post JSON data to Rest with URLEncoded query paramaters
I'm learning feathersjs as per below link
http://feathersjs.com/quick-start/
I need to run below command and monitor the output at http://localhost:3000/todo
curl 'http://localhost:3000/todos/' -H 'Content-Type: application/json' --data-binary '{ "text": "Do something" }'
When I tried to run below on cmd, it shows 'curl' is not recognized in cmd prompt.
If I tried to run it using git-bash.exe, bash.exe or sh.exe (in Git/bin or shell.w32-ix86), Cygwin.bat (in cygwin64), it will run fine and showing result in browser.
[{"text":"Do something","id":0}]
But if tried to run it by including into my PATH "C:\Program Files\Git\mingw64\bin, which has curl.exe", I will be getting below error, but "C:\Program Files\Git\usr\bin" will do just fine...
curl: (1) Protocol "'http" not supported or disabled in libcurl
curl: (6) Couldn't resolve host 'application'
curl: (6) Couldn't resolve host text'
curl: (6) Couldn't resolve host 'Do something'
curl: (3) [globbing] unmatched close brace/bracket in column 1
I managed to remove the error with below command
curl "http://localhost:3000/todos/" -H "Content-Type: 'application/json'" --data-binary "{ 'text': 'Do something' }"
But the resulting output will have the Json object "text" missing...
[{"text":"Do something","id":0},{"id":1}]
Question:
1) After modifying the command, the Json object is not parsed successfully. Is there a syntax problem?
2) If there is no syntax problem, does this means that curl need to be run in Unix environment as per original attempt, that it cant be run in cmd directly, but will function ok in bash, cygwin, etc2?
3) What is the difference between curl.exe in C:\Program Files\Git\usr\bin and C:\Program Files\Git\mingw64\bin, which has curl.exe?
Update:
Not OK Raw Cap output
http.content_type == "'application/json'"
OK Raw Cap output
http.content_type == "application/json"
Update2:
Removing single quote in application/json on the 2nd command... shows error

Update 3:
Tried to replace libcurl-4.dll used by curl.exe. Downloaded libcurl from "http://curl.haxx.se/download.html", MingW32 from "http://sourceforge.net/projects/mingw/files/MSYS/" and added "C:\MinGW\bin" to PATH. Then grep -rl "libcurl.dll" . | xargs sed -i 's/libcurl.dll/libcurl-4.dll/g' to create libcurl-4.dll as per suggested "http://curl.haxx.se/mail/lib-2010-11/0174.html". Then execute ./buildconfig, make, make install. Then copied the libcurl-4.dll to C:\Program Files\Git\mingw64\bin folder, but the result is the same...
Update 4
Changing origin of curl.exe but still using same command, shows error on the mingw64 version. I'm suspecting that mingw64 curl need special escaping to make it work?
C:\Users\testUser\Documents\Framework\Javascript\featherstestNewService>"C:\Program Files\Git\mingw64\bin\curl.exe" 'http://localhost:3000/todos/' -H 'Content-Type: application/json' --data-binary '{ "text": "Do something" }'
curl: (1) Protocol "'http" not supported or disabled in libcurl
curl: (6) Couldn't resolve host 'application'
curl: (6) Couldn't resolve host 'text'
curl: (6) Couldn't resolve host 'Do something'
curl: (3) [globbing] unmatched close brace/bracket in column 1
C:\Users\testUser\Documents\Framework\Javascript\featherstestNewService>"C:\Program Files\Git\usr\bin\curl.exe" 'http://localhost:3000/todos/' -H 'Content-Type: application/json' --data-binary '{ "text": "Do something" }'
{"text":"Do something","id":38}
Update 5
From manual... curl --manual
-d, --data <data>
(HTTP) Sends the specified data in a POST request to the HTTP
server, in the same way that a browser does when a user has
filled in an HTML form and presses the submit button. This will
cause curl to pass the data to the server using the content-type
application/x-www-form-urlencoded. Compare to -F, --form.
-d, --data is the same as --data-ascii. --data-raw is almost the
same but does not have a special interpretation of the # charac-
ter. To post data purely binary, you should instead use the
--data-binary option. To URL-encode the value of a form field
you may use --data-urlencode.
If any of these options is used more than once on the same com-
mand line, the data pieces specified will be merged together
with a separating &-symbol. Thus, using '-d name=daniel -d
skill=lousy' would generate a post chunk that looks like
'name=daniel&skill=lousy'.
If you start the data with the letter #, the rest should be a
file name to read the data from, or - if you want curl to read
the data from stdin. Multiple files can also be specified. Post-
ing data from a file named 'foobar' would thus be done with
--data #foobar. When --data is told to read from a file like
that, carriage returns and newlines will be stripped out. If you
don't want the # character to have a special interpretation use
--data-raw instead.
So I tried...
C:\Users\testUser>"C:\Program Files\Git\mingw64\bin\curl.exe" "http://localhost:3000/todos/" -H "'Content-Type:' 'application/json'" --data-binary text=doing --data complete=false
{"text":"doing","complete":"false","id":145}
C:\Users\testUser>"C:\Program Files\Git\mingw64\bin\curl.exe" "http://localhost:3000/todos/" -H "'Content-Type:' 'application/json'" --data-binary text=ding
{"text":"ding","id":146}
But I cant figure out how to make more than 1 word for the JSON object for example instead of "doing", I need "doing something". Seems that MingW64 git curl is accepting different format...
After modifying the curl command it works for you, because you need to use double quote for windows system.
After modifying the command, you have mistakenly added single quote around the application/json. That's why despite of having working curl command server was unsure what you have exactly sent to them!
"Content-Type: 'application/json'"
^ ^ notice the unwanted singles
So it should be
"Content-Type: application/json"
If you do not provide path for any binary (i.e. curl.exe, mysql.exe, php.exe, etc) then system looks for them inside the available paths provided in PATH variable and if they found multiple path there then it will only select one, and I don't know which one!

i need to increment the userb and usere but when i write my variable in curl , and when i try it i get nothing
(1..180000).step(20000)do |userb|
(20000..180000).step(20000)do |usere|
curl = %x[ curl -i -s -H "Host: xxxx" "http://XXXXX/scripts/exportStatsCsv/testA1?start='+ userb +'&end='+ usere +'&startDate='#{#array_timestampdate[0]}'&endDate='#{#array_timestampdate[1]}'" ] sleep(10)
end
end
Try running your code with warnings and debugging turned on:
ruby -cW2 path/to/your/code
You should see something like:
syntax error, unexpected tIDENTIFIER, expecting keyword_end
... sleep(10)
... ^
You need to do this as a first step when you run into a problem. Ruby will give you more detailed information about problems with the script when warnings are enabled and set to their highest value. Here's what the flags mean:
-c check syntax only
-W[level=2] set warning level; 0=silence, 1=medium, 2=verbose
You're getting this error, because sleep(10) needs to be executed as a separate statement. You can either insert ; between it, and the call to cURL, or put it on its one line. I'd recommend the second option in order to make the commands easier to read.
Also, I'd highly recommend using the Curb gem instead of launching cURL in a sub-shell like you are. You're losing flexibility and wasting CPU time having Ruby, then the OS, create a new shell to launch cURL.
Finally, you need to learn to write your code more clearly or you'll paint yourself into corners of confusion in no time. Here's a starting point for how I'd write the code:
require 'uri'
#array_timestampdate = ['start_date', 'end_date']
(1..180000).step(20000) do |userb|
(20000..180000).step(20000) do |usere|
uri = URI.parse('http://XXXXX/scripts/exportStatsCsv/testA1')
uri.query = URI.encode_www_form(
{
'start' => userb,
'end' => usere,
'startDate' => #array_timestampdate[0],
'endDate' => #array_timestampdate[1]
}
)
curl = %Q[ curl -i -s -H "Host: xxxx" "#{uri.to_s}" ]
puts curl
end
end
With a little example of the output:
>> curl -i -s -H "Host: xxxx" "http://XXXXX/scripts/exportStatsCsv/testA1?start=1&end=20000&startDate=start_date&endDate=end_date"
...
>> curl -i -s -H "Host: xxxx" "http://XXXXX/scripts/exportStatsCsv/testA1?start=160001&end=180000&startDate=start_date&endDate=end_date"
