如何在angularjs中将参数传递给$http? [英] How to pass parameters to $http in angularjs?

问题描述

假设我有两个输入框，对应的 ng-model 为 fname 和 lname.如果我将 http 请求称为:

Assume that I have two input boxes with corresponding ng-model as fname and lname. If I call http request as :

$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})

它会调用 url 吗:

will it call to the url :

/search?fname=fname&lname=lname

我在后端(python)遇到的错误是:

The error I am getting at the backend(python) is :

cannot concatenate str and nontype objects.

这些参数不是作为字符串发送的吗?如果没有，如何解决这个问题?

Are these parameters not sent as strings? If not, how to get around with this?

推荐答案

这是你的做法:

$http.get("/url/to/resource/", {params:{"param1": val1, "param2": val2}})
    .then(function (response) { /* */ })...

Angular 负责对参数进行编码.

Maxim Shoustin 的回答不起作用({method:'GET', url:'/search', jsonData} 不是有效的 JavaScript 文字)，而 JeyTheva 的回答虽然简单，但很危险它允许 XSS(连接它们时不安全的值不会被转义).

Maxim Shoustin's answer does not work ({method:'GET', url:'/search', jsonData} is not a valid JavaScript literal) and JeyTheva's answer, although simple, is dangerous as it allows XSS (unsafe values are not escaped when you concatenate them).
