javascript - Fetch POST with some headers -

-

i want post data using fetch function. i've been testing curl command aim of find correct response. found command works want looks this:

curl -0 -a '' -x post -h 'accept: ' -h 'content-type: text/xml;    charset="utf-8"' -h "soapaction: \"urn:belkin:service:basicevent:1#setbinarystate\"" --data '<?xml version="1.0" encoding="utf-8"?><s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/"><s:body><u:setbinarystate xmlns:u="urn:belkin:service:basicevent:1"><binarystate>0</binarystate></u:setbinarystate></s:body></s:envelope>' -s http://192.168.1.48:49153/upnp/control/basicevent1

the parameters of fetchthat i've setted:

fetch('http://192.168.1.48:49153/upnp/control/basicevent1', {  method: 'post',   headers: {    'accept' : '',    'content-type': text/xml; charset="utf-8",    'soapaction': "urn:belkin:service:basicevent:1#setbinarystate"  },  body: ('<?xml version="1.0" encoding="utf-8"?><s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/"><s:body><u:setbinarystate xmlns:u="urn:belkin:service:basicevent:1"><binarystate>0</binarystate></u:setbinarystate></s:body></s:envelope>') })

i don't know if problem in http version or other headers settings receive error response.

fetch api uses promises handle callback results.

in case:

     fetch('http://192.168.1.48:49153/upnp/control/basicevent1', {      method: 'post',       headers: {        'accept' : '',        'content-type': 'text/xml; charset="utf-8"',        'soapaction': "urn:belkin:service:basicevent:1#setbinarystate"      },      body: ('<?xml version="1.0" encoding="utf-8"?><s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/" s:encodingstyle="http://schemas.xmlsoap.org/soap/encoding/"><s:body><u:setbinarystate xmlns:u="urn:belkin:service:basicevent:1"><binarystate>0</binarystate></u:setbinarystate></s:body></s:envelope>')      }).catch(function(err) {        // error :(      });

also, content-type should "application/json; charset=utf-8".
