angularjs - $http.get doesn't work with arrays with only one element. How do I specify the param type? -


i'm using angular's $http.get() method query api:

var arr = ['foo','bar']; return $http.get("api/foo", {   params: { sampleids: arr} });

this results in request /api/foo?sampleids=115&sampleids=116 works ok. if reduce size of array single element, however, becomes /api/foo?sampleids=115, express (node.js) fails interpret array.

if angular sent query /api/foo?sampleids[]=115 instead, should work fine. there way can tell that?

you can use paramserializer property in request config customize how parameters object gets converted string.

return $http.get("api/foo", {   params: { myarray: arr},   paramserializer: function (params) {       // return string...   } });

you can @ default implementation here, if you're not sure how go serializing object: https://github.com/angular/angular.js/blob/master/src/ng/http.js#l27.

additionally, if provide string rather function, service name - helpful if want reuse it. there's $httpparamserializerjqlike service provided default, serializes them in same format jquery's param() function.

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac
