Angular js $http.get in $http.get 不起作用

Question

我有用户列表，我会给这个用户看。用户有未读消息并且没有写餐单，我想在主 http.get 请求中拖曳 http.get 以获取所需的信息，但我的问题是它异步工作，因此未读消息和周值不会改变。我该怎么做。提前致谢

$http.get('http://example.com/users').success(function(response){         
var data=response;
if(data==null || data.length<=0){
return;
}
var date2 = new Date();
var users=[];
for(var i=0;i<data.length;i++){
var diffDays=0;
if(data[i].uyelikBaslangicTarihi=="0"){                             
continue;
}
var from = data[i].uyelikBaslangicTarihi.substring(0,10).split("/");                    
var date1 = new Date(from[2], (from[1] - 1), from[0]);                  
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24)); 
if(diffDays>28 || diffDays<0){                              
continue;
}
var week=diffDays/7;
week=parseInt(week);
if(diffDays/7>0)
week++;                     
if(week!=0)
week--;
var unloadweek=week+1;
var unreadmessage=0;

$http.get('http://example.com/menus?userId=' + data[i]._id + '&haftaSayisi=' + week).success(function(response){        
if(response==null || response.length==0){unloadweek= "";}
else{unloadweek= week;}          
});
$http.get('http://example.com/sorus?userId=' + data[i]._id + '&okundu=0').success(function(response){   
console.log(response);
if(response==null){ unreadmessage= 0;}
else{unreadmessage = response.length;}       
});
var color="white"       
var gender='mars'   
if(data[i].cinsiyet=="Kadın")
gender='venus';
var user={
id:data[i]._id,
name:data[i].ad,
gender:gender,
weight:data[i].kilo,
height:data[i].boy,
birthday:data[i].dogum_tarihi,
email:data[i].email,
src:"http://example.com/images/"+data[i]._id+".jpeg",
color:color,
week:unloadweek,
unreadmessage:unreadmessage
}
if(data[i].uyelikBaslangicTarihi!="" && data[i].uyelikBaslangicTarihi!="0" && data[i].rol!="admin")
users.push(user);
}
$scope.customers=users;

})
.error(function(err){
alert("hata");
}

Answer 1

你需要正确地链接你的HTTP请求和承诺。请参阅文档(见下文(。

另外，请尊重该上下文中变量的范围 -unloadweek变量在 get 之前定义，然后在下一个 $http.get resolve 函数中使用 - 以及 for 循环中的所有变量。

不确定您的代码结构是否也可能存在问题:)建议改进;-(
