cURL POST command line on WINDOWS RESTful service

Question

My problem   Using the command line tool to curl my localhost server while sending some data along with my POST request is not working   What seems to be causing the error   Imagine something like this   curl -i -X POST -H  Content-Type  application json  -d    data1    data goes here    data2    data2 goes here    http localhost path to api   Result of the returning data  curl   6  Could not resolve host  application  No data record of requested type curl   6  Could not resolve host  data goes here   No data record of requested type curl   6  Could not resolve host  data2  No data record of requested type curl   3   globbing  unmatched close brace bracket at pos 16   After some searching i figured out that problem couldn t be the sintax used for the request since it works on UNIX shells       Are you possibly using Windows  That so looks like a completely broken shell    that doesn t properly deal with single-quotes vs double-quotes     I just tried that command line and it worked fine on my linux box     http   curl haxx se mail archive-2011-03 0066 html   I tried to work around with those   escaping it    but it still didn t work  2      curl -i -X POST -H  Content-Type  application json  -d     data1      data goes here      data2      data2 goes here     http    localhost path to api   3      curl -i -X POST -H  Content-Type  application json  -d     data1      data goes here      data2      data2 goes here     http    localhost path to api   So i gave up   Windows seems to messing up with the JSON object sent on POST

At least for the Windows binary version I tested, (the Generic Win64 no-SSL binary, currently based on 7.33.0), you are subject to limitations in how the command line arguments are being parsed. The answer by xmas describes the correct syntax in that setting, which also works in a batch file. Using the example provided:

curl -i -X POST -H "Content-Type: application/json" -d "{""data1"":""data goes here"",""data2"":""data2 goes here""}" http:localhost/path/to/api

A cleaner alternative to avoid having to deal with escaped characters, which is dependent upon whatever library is used to parse the command line, is to have your standard json format text in a separate file:

curl -i -X POST -H "Content-Type: application/json" -d "@body.json" http:localhost/path/to/api

We can use below Curl command in Windows Command prompt to send the request  Use the Curl command below  replace single quote with double quotes  remove quotes where they are not there in below format and use the   symbol  curl http   localhost 7101 module url     -d  D  request xml     -H  quot Content-Type  text xml quot      -H  quot SOAPAction  process quot      -H  quot Authorization  Basic xyz quot      -X POST

I ran into the same issue on my win7 x64 laptop and was able to get it working using the curl release that is labeled Win64 - Generic w SSL by using the very similar command line format   C  Projects curl-7 23 1-win64-ssl-sspi gt curl -H  Content-Type  application json  -X POST http   localhost someapi -d     Name     Test Value       Which only differs from your 2nd escape version by using double-quotes around the escaped ones and the header parameter value  Definitely prefer the linux shell syntax more

Try to use double quotes     instead of single ones      To preserve JSON format quotes  try doubling them       To preserve quotes inside data  try to double-escape them like this          curl     -d     data1      data1 goes here      data2      data2 goes here     curl     -d     data      data     abc     goes here

Another Alternative for the command line that is easier than fighting with quotation marks is to put the json into a file  and use the   prefix of curl parameters  e g  with the following in json txt      syncheader           servertimesync     20131126121749        deviceid     testDevice          then in my case I issue   curl localhost 9000 sync -H  Content-type application json  -X POST -d  json txt   Keeps the json more readable too
