i;m tring to get send curl GET command and get the response back i always failed for 2 reason ,
the urls in the request should be encoded utf8
and the 2nd one the i always get curl: (6) Couldn't resolve host for

I am new to using API and not quite sure how to use the CoinGlass API to retrieve data.
According to the documentation, it supports using the curl command
curl --location --request GET 'https://open-api.coinglass.com/api/pro/v1/futures/funding_rates_chart?symbol=BTC&type=C' \
--header 'coinglassSecret: fabe11b61f5a4963a4227f4ac2cbcf2f'
https://coinglass.github.io/API-Reference/#liquidation-chart
However, when I tried to run it in the command prompt in Windows 10, it gave me the below error.
C:\Users\User1>curl --request GET 'https://open-api.coinglass.com/api/pro/v1/futures/funding_rates_chart?symbol=BTC&type=C' --header 'coinglassSecret: fabe11b61f5a4963a4227f4ac2cbcf2f'
curl: (3) URL using bad/illegal format or missing URL
Please kindly point me to right direction, million thanks!
I removed the single quotes around the URL. Executed in Win 10 CMD prompt, and got this
curl --request GET https://open-api.coinglass.com/api/pro/v1/futures/funding_rates_chart?symbol=BTC&type=C --header 'coinglassSecret: fabe11b61f5a4963a4227f4ac2cbcf2f'
{"code":"30001","msg":"secret invalid","success":false}
The system cannot find the file specified.
Error occurred while processing: C.
The system cannot find the file specified.
Error occurred while processing: --header.
The filename, directory name, or volume label syntax is incorrect.
I have a cURL call like this:
curl --silent --max-filesize 500 --write-out "%{http_code}\t%{url_effective}\n" 'http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.[200-210].dmg' -o /dev/null
This call generates a list of of URLs with the HTTP code (200 or 404 normally) like this:
404 http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.203.dmg
404 http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.204.dmg
200 http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.205.dmg
404 http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.206.dmg
The only valid URLs are the ones preceded by the 200 HTTP code, so I would like to put a regular expression in the cURL so that it only downloads the lines that start with 200
Any ideas on how to do this without being a bash script?
Thank you in advance
You can use the following :
curl --silent -f --max-filesize 500 --write-out "%{http_code}\t%{url_effective}\n" -o '#1.dmg' 'http://fmdl.filemaker.com/maint/107-85rel/fmpa_17.0.2.[200-210].dmg'
This will try to reach every url and when it's not a 404 nor too large download it into a file whose name will be based on the index in the url.
The -f flag makes it avoid to output the content of the response when the HTTP code isn't a success one, while the -o flag specifies an output file, where #1 corresponds to the effective value of your [200-210] range (adding other [] or {} would let you refer to other parts of the URL by their index).
Note that during my tests, the --max-filesize 500 flag prevented the download of the only url which didn't end up in a 404, fmpa_17.0.2.205.dmg
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 testing malformed HTTP requests on OSX, but I can't workout how to make a request with a missing/malformed http version.
Curl seems to only allow valid presets (--http1.0, --http1.1, --http1)
Whats the easiest way to construct a request without "http version"?
Example:
Given the following commands create the following request lines:
Ex1.
command: curl -i http://localhost:8080/cat.jpg?v=1
request: GET cat.jpg?v=1 HTTP/1.1
Ex2.
command: curl -i http://localhost:8080/cat.jpg?v=1 --http1.0
request: GET cat.jpg?v=1 HTTP/1.0
Wanted
How could I create the following
command: ???
request: GET cat.jpg?v=1 (missing http version)
EDIT: ANSWER
curl only deals with valid requests. netcat is an alternative that has more control.

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!
