Error Handling

  • simple error control
api.getInfo().catch(function(e){
    console.log(e.message)
})
  • technical error control
var errors = require('zaif.jp/errors')
api.getInfo()
    .catch(errors.HttpApiError, function (reason) {
        // API ERROR
        console.log(reason.message, "API", reason.error_code)
    })
    .catch(errors.StatusCodeError, function (reason) {
        // HTTP STATUS ERROR(404 or 500, 502, etc...)
        console.log("HTTP StatusCodeError " + reason.statusCode, "HTTP", reason.statusCode)
    })
    .catch(errors.RequestError, function (reason) {
        // REQUEST ERROR(SYSTEMCALL, TIMEOUT)
        console.log(reason.message, "SYSCALL", reason.error.code)
    })
    .catch(function(e){
        // OTHER ERROR
        console.log(e.message)
    })

Tuning Network Parameter

  • Attention! Global Parameter
  • Setting - KeepAlive Connection
  • Setting - Timeout Second
var zaif = require('zaif.jp');

var appInitialize = function(){
    zaif.Constant.OPT_KEEPALIVE = true;
    zaif.Constant.OPT_TIMEOUT_SEC = 3;
}

var main = function(){
    appInitialize();
}

main()
