[请求标头中用于将json从angularjs发送到rest api的内容类型

问题描述 投票：0回答：2

我正在服务器上运行一个Angular项目，并尝试调用在另一台服务器上运行的其余api我在rest api的过滤器中添加了响应标头，如[

responce.setHeader("Access-Control-Allow-Origin", "*");
responce.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
responce.setHeader("Access-Control-Max-Age", "3600");
responce.setHeader("Access-Control-Allow-Headers", "x-requested-with");

在我添加的app.config中

$httpProvider.defaults.headers.common = {};
    $httpProvider.defaults.headers.post = {};
    $httpProvider.defaults.headers.put = {};
    $httpProvider.defaults.headers.patch = {};

我使用restangular进行http调用，在app.config中将baseURL设置为运行restapi的服务器当调用发送字符串时，它工作正常，但是当我尝试发送json时，我得到了异常

        Restangular.all('userById').post(userName).then(function(result) {};        //working 
    //the rest receives the userName in a string 

    Restangular.all('saveUser').post(userInfo).then(function(result) {};        //not working
    //the rest receives the userInfo in a bean

我发送json时收到此消息

同样在传递json时，请求标头也为

Accept:*/*
Accept-Encoding:gzip,deflate,sdch
Accept-Language:en-US,en;q=0.8
Connection:keep-alive
Content-Length:88
Content-Type:text/plain;charset=UTF-8                   //has to be application/json
Host:172.16.177.65:8580
Origin:http://localhost:8180
Referer:http://localhost:8180/admin/indexHome.html
User-Agent:Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36

所以如何将请求标头的内容类型更改为json

angularjs restangular request-headers

您需要在客户端上将Content-Type标头设置为application/json。

或者您可以将其添加到您的app.config
