微信小程序 POST请求
微信小程序开发中网络请求必不可少.GET.POST请求是最常用的.GET请求，POST请求的时候有好几个坑.我已经为大家填好了.

按照文档,肯定是这么写.那就入坑了.
1. 'Content-Type': 'application/json'用在get请求中没问题.
POST请求就不好使了.需要改成: "Content-Type": "application/x-www-form-urlencoded"
2016.11.10更新:有同学在将content-type 修改为小写后,post请求成功.
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.
下面直接贴代码:

获取应用实例
var app = getApp()
Page( {
data: {
toastHidden: true,city_name: '',},onLoad: function() {
that = this;
wx.request( {
url: "http://op.juhe.cn/oneBox/weather/query",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' );
