जबरदस्ती तरीके से GET OR POST करें

/* By Default if you send only url then automatically it will recognize as GET Method and if service having parameters with, Then automatically will convert to POST Method. But I observed some of the services having only URL but are POST Type. For the purpose you can forcefully make the method as you want. As bellow:  */
