将自定义函数导入openCPU

Question

如何使用openCPU JavaScript API或jQuery向openCPU（作为本地服务器运行）库添加自定义（以字符串形式）R函数？

使用类似

的内容

var myfunc = "ff <- function(x,y) { x+y }";
$.post("http://localhost:8483/R/call/base/identity/save",
       {x : myfunc},
       function(res) {...});

在浏览器中产生以下错误

Cross-Origin Request Blocked: The Same Origin Policy disallows 
reading the remote resource at http://localhost:8483/R/call
/base/identity/save. (Reason: CORS header 'Access-Control-Allow-
Origin' missing)

Answer 1

您应该在ajax帖子设置中使用crossDomain：true

$.post("http://localhost:8483/R/call/base/identity/save",
       crossDomain: true,
       {x : myfunc},
       function(res) {...});
