哪些是AngularJS跨域REST调用正确的架构模式？ [英] What is the correct architectural pattern for cross domain REST call in AngularJS?

问题描述

我创建的是直接从客户端打Salesforce的REST API的AngularJS服务。不过，我一直无法得到它的工作，由于同一产地的限制。即使访问的非认证REST服务，努力当两个$ HTTP，$ http.json和Ajax。我也试过很多JSON，JSONP等。

的组合

既然我有这么多的问题，我想，我的一般做法是不正确。也许我需要设置为这个代理服务器？我的后端是火力地堡，所以我现在还没有我自己的服务器。

我不相信Salesforce的API支持CORS，我不能改变这种状况。

下面是我所使用$ HTTP和Ajax尝试的例子。

 收益$ http.jsonp（'https://na1.salesforce.com/services/data/'，{
标题：{
    内容类型：应用/ JSON的，接受：应用/ JSON
}}）。
                成功（功能（数据，状态，头，配置）{                    回调（数据）;
                    console.debug（data.json）;
                }）。
                错误（功能（数据，状态，头，配置）{
                    console.debug（getVersions：无法检索数据：+的eval（数据））;
                }）;
$阿贾克斯（{
              网址：'https://na15.salesforce.com/services/data'，
          键入：GET，
              数据类型：JSONP
              beforeSend：功能（xhrObj）{
                                  xhrObj.setRequestHeader（内容类型，应用/ JSON）;
                                  xhrObj.setRequestHeader（接受，应用/ JSON）;
                                  xhrObj.setRequestHeader（X-要求，用，XMLHtt prequest）;
                              }，
              成功：功能（数据）{
                  console.debug（数据）;
                  回调（数据）;
              }，
              错误：功能（数据）{              }
          }）;
 

解决方案

您需要进入Salesforce内再CORS远程设置和白名单域名...

我有同样的问题，它似乎已经解决了这个问题。

I've created an AngularJS service that is hitting the Salesforce REST API directly from the client. However, I haven't been able to get it working due to same origin restrictions. Even when accessing non authenticated REST services and trying both $http, $http.json and Ajax. I've also tried lots of combinations of Json, Jsonp etc.

Given that I've had so many issues I'm thinking that my general approach is incorrect. Perhaps I need to setup a proxy server for this? My backend is Firebase so I don't currently have my own server.

I don't believe that the Salesforce API supports CORs and I cannot change that.

Here is an example of what I tried using $http and Ajax.

return $http.jsonp('https://na1.salesforce.com/services/data/',{
headers: {
    'Content-type': 'application/json', 'Accept': 'application/json'
}}). 
                success(function (data, status, headers, config) {

                    callback(data);
                    console.debug(data.json);
                }).
                error(function (data, status, headers, config) {
                    console.debug("getVersions: failed to retrieve data: "+eval(data));
                });


$.ajax({
              url: 'https://na15.salesforce.com/services/data',
          type: "GET",
              dataType: "jsonp",
              beforeSend: function(xhrObj){
                                  xhrObj.setRequestHeader("Content-Type","application/json");
                                  xhrObj.setRequestHeader("Accept","application/json");
                                  xhrObj.setRequestHeader("X-Requested-With", "XMLHttpRequest");
                              },
              success: function (data) {
                  console.debug(data);
                  callback(data);
              },
              error: function(data) {

              }
          });

解决方案

You need to go into Remote Settings within SalesForce then CORS and whitelist the domain name...

I had the same issue and it seemed to have resolved the issue.
