React-native (iii)--JS Network request Resolution

The homepage defines the URL interface The JS file, creates, the invocation actually and OC almost.

' Use strict ';
var BASE = ' http://XXXXXX/';

function API (address) {return
	
	BASE + address;
}

function Gethomeapi () {return
	API (' api/xxxx/xxxx ');
}

Module.exports = {
	homeapi:gethomeapi,
};

Call:

var Cfapi = require ('.. /.. /network/api ');

Network request, parse JSON with the help of fetch, the specific code is as follows:

Fetchdata:function () {
    fetch (CFAPI). Homeapi ())
    . Then (response) => {
      //console.log (' response-----: ', response);
      return Response.json ();
    })
    . Then (responsedata) => {
      //console.log (' JSON-----: ', responsedata);
        This.setstate ({
          dataSource:this.state.dataSource.cloneWithRows (responsedata.body),
          loaded:true
        });
    }). Done ();
  },

This is done, and the back is filled with data.

Sharing tips:

Debug: Xcode must be set to debug mode to be effective, if degug in Safari when the program crash, the run of the demo can be deleted.

Use: Module.exports = homelist;,module.exports The following parameters can be understood as the current object created.
