面向新手系列《五》POST请求，服务器接收不到data参数问题，邮件接收服务器与端口

需要修改以下三个步骤

1. 'Content-Type': 'application/json'用在get请求中没问题.

2. 加上method: "POST"

3.data: { cityname: "上海", key: "1430ec127e097e1113259c5e1be1ba70" }写成json格式这样也是请求不到数据的.需要转格式.

var Util = require( '../../utils/util.js' ); data: Util.json2Form( { cityname: "上海", key: "1430ec127e097e1113259c5e1be1ba70" }),  

3.2

function json2Form(json) { var str = []; for(var p in json){ str.push(encodeURIComponent(p) + "=" + encodeURIComponent(json[p])); } return str.join("&"); } module.exports = { json2Form:json2Form, }  

1：

//获取应用实例 var app = getApp() Page( { data: { toastHidden: true, city_name: '', }, onLoad: function() { that = this; wx.request( { url: "", header: { "Content-Type": "application/x-www-form-urlencoded" }, method: "POST", //data: { cityname: "上海", key: "1430ec127e097e1113259c5e1be1ba70" }, data: Util.json2Form( { cityname: "上海", key: "1430ec127e097e1113259c5e1be1ba70" }), complete: function( res ) { that.setData( { toastHidden: false, toastText: res.data.reason, city_name: res.data.result.data.realtime.city_name, date: res.data.result.data.realtime.date, info: res.data.result.data.realtime.weather.info, }); if( res == null || res.data == null ) { console.error( '网络请求失败' ); return; } } }) }, onToastChanged: function() { that.setData( { toastHidden: true }); } }) var that; var Util = require( '../../utils/util.js' );

POST请求就不好使了.需要改成: "Content-Type": "application/x-www-form-urlencoded"
