1.get請求?

1.創(chuàng)建服務(wù)，并引入

import{Injectable}from'@angular/core';

import{Http}from'@angular/http';

import'rxjs/add/operator/map';

@Injectable()

exportclassCategoryListServiceProvider{

constructor(publichttp:Http) {

}

publicgetList(params) {

console.log(params);

returnnewPromise((resolve,reject)=>{

this.http.get('http://api.maidanfan.la/UserApp/Index/categoryMerchant',{search:params})

.map(res=>res.json())

.subscribe(data=>{

resolve(data);

},err=>{

reject(err);

})

})

}

}

2.在需要調(diào)用的ts文件引入以下服務(wù)和方法

import{Component}from'@angular/core';

import{IonicPage,NavController,NavParams}from'ionic-angular';

import{URLSearchParams}from'@angular/http';

import{CategoryListServiceProvider}from'./../../../providers/category-list-service/category-list-service';

3調(diào)用服務(wù)

exportclassCategoryListPage{

constructor(publicnavCtrl:NavController,publicnavParams:NavParams,publicservice:CategoryListServiceProvider) {

letgid=navParams.data;

letparams:URLSearchParams=newURLSearchParams();

params.set('city_id','1');//城市ID

params.set('lat','34.2351921');

params.set('lng','108.9421249');

params.set('p','1');

params.set('order','1');

params.set('group_id',gid);

this.service.getList(params).then(

data=>{

letdataString=JSON.stringify(data);

letdataJson=JSON.parse(dataString);

console.log(dataJson)

})

}

ionViewDidLoad() {

console.log('ionViewDidLoad CategoryListPage');

}

}

2.解決post請求問題

1.服務(wù)和get不同

2.使用先引入以下

3.使用headers請求頭，可代參
