Flutter 基于dio网络请求封装
import 'package:dio/dio.dart';
import 'dart:convert';
class BaseRequest {
/*分页默认起始页*/
static final intkStartIndex =1;
/*分页默认每一页数量*/
static final intkPageSize =10;
/*请求成功*/
static final intkCodeSuccess =0;
/*请求地址*/
static final StringkHttpHostName ="http://127.0.0.1:8080";
/*登录*/
static final StringkUrlAccountLogin =kHttpHostName +"/user/login";
static requestWithUrl(String url, Map parameters, successBlock(int code, String message, Object data), errorBlock(error))async {
try {
Dio dio =new Dio();
Response response =await dio.request(
url,
queryParameters: parameters,
options:Options(
method:"POST"
)
);
print("请求地址：" + url);
print("请求参数：" + parameters.toString());
print("返回参数：" + response.toString());
Map map = json.decode(response.toString());
int code = map["code"];
String msg = map["msg"];
Object data = map["data"];
return successBlock(code,msg,data);
}on DioErrorcatch (error) {
print("请求地址：" + url);
print("请求参数：" + parameters.toString());
print("请求报错：" + error.toString());
return errorBlock(error);
}
}
}
调用：
BaseRequest.requestWithUrl(BaseRequest.kUrlAccountLogin, {
"account":"18761661234",
"password":"111111"
}, (int code, String message, Object data) {
if (code == BaseRequest.kCodeSuccess) {
}else {
}
}, (error) {
});
