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: "de" },  
      data: Util.json2Form( { cityname: "上海", key: "fddf" }),  
      complete: function( res ) {  
      }
})

微信小程序示例

wx.request({
  url: 'test.php', //仅为示例，并非真实的接口地址
  data: {
        x: '' , 
        y: ''
   }, 
  header: { 
    'content-type': 'application/json' 
  }, 
  success: function(res) { 
    console.log(res.data) 
  }
})

method: 'POST',
    header：{
      'content-type':'application/x-www-form-urlencoded'

  wx.request( { 
   url: "url", 
   header: {

   }, 
   method: "POST", 
   data: {}, 
   complete: function( res ) { 
    console.log(res.data)
    }); 
    if( res == null || res.data == null ) { 
     console.error( '网络请求失败' ); 
     return; 
    } 
   } 
  }) 
 },
