需要修改以下三个步骤 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"
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. 3.1var 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,
}
整体示例代码: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' ); 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,
