Assume I’m using the boilerplate Ti.Network.createHTTPClient call with an “onload” & “onerror”.
...
var xhr = Ti.Network.createHTTPClient({ ... });
myObj = { mydata:
{ myitems: [
{ mainID:7452, someOption:87, theDate:'2012-10-23' },
{ mainID:2342, someOption:27, theDate:'2011-06-03' },
{ mainID:1914, someOption:43, theDate:'2012-02-14' }
]
}
};
...
var strMyObj = JSON.stringify(myObj);
Ti.API.info("strMyObj = " + strMyObj);
xhr.open("POST", "http://www.yourPathHere.com/yourWebServiceName");
xhr.setRequestHeader('Accept','application/json');
xhr.setRequestHeader('Content-Type','application/json');
xhr.send( strMyObj );
...
Works in CURL, not in Titanium
I ran into this issue first. The following CURL command worked in Terminal:
curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d "{mydata:{myitems:[{mainID:7452, someOption:87, theDate:'2012-10-23'}]}}"
http://www.yourPathHere.com/yourWebServiceName
In Titanium I kept getting HTTP response status “403” because I made stupid mistake, using “PUT” instead of “POST” in xhr.open(). Good times.
The “-i” stands for “include”, “-H” specifies an HTTP header. The “-X” in front of “POST” tells curl to use something other than “GET”. “-d” stands for data to include in your HTTP POST, mimicking an HTML form request. Here’s a list of CURL flags.
JSON.stringify
After fixing that, I got HTTP response status “500”, by just doing “xhr.send(myObj);”.
Thanks to some debugging by my backend dev Wes, it turned out the service simply wanted the data formatted as a String. He tried, taking the quotes off the {mydata…} line in the CURL command and got the same status 500 error in Terminal and via Chrome’s console:
curl -i -H "Accept: application/json" -H "Content-Type: application/json" -X POST -d {mydata:{myitems:[{mainID:7452, someOption:87, theDate:'2012-10-23'}]}}
http://www.yourPathHere.com/yourWebServiceName
curl: (6) Could not resolve host: someOption:87,; nodename nor servname provided, or not known
