How to pass payload via JSON file for curl

Question

I can successfully create a place via curl executing the following command     curl -vX POST https   server api v1 places json -d     auth token B8dsbz4HExMskqUa6Qhn amp      place name  Fuelstation Central amp      place city  Grossbeeren amp      place address  Buschweg 1 amp      place latitude  52 3601 amp      place longitude  13 3332 amp      place washing  true amp      place founded at year  2000 amp      place products    diesel amp      place products    benzin       The server returns HTTP 1 1 201 Created  Now I want to store the payload in a JSON file which looks like this      testplace json      auth token     B8dsbz4HExMskqUa6Qhn      name     Fuelstation Central      city     Grossbeeren      address     Buschweg 1      latitude    52 3601     longitude    13 3332     washing    true     founded at year    2000     products      diesel   benzin       So I modify the command to be executed like this     curl -vX POST http   server api v1 places json -d  testplace json   This fails returning HTTP 1 1 401 Unauthorized  Why

curl sends POST requests with the default content type of application x-www-form-urlencoded  If you want to send a JSON request  you will have to specify the correct content type header     curl -vX POST http   server api v1 places json -d  testplace json   --header  Content-Type  application json    But that will only work if the server accepts json input  The  json at the end of the url may only indicate that the output is json  it doesn t necessarily mean that it also will handle json input  The API documentation should give you a hint on whether it does or not        The reason you get a 401 and not some other error is probably because the server can t extract the auth token from your request
