我正在编写一些代码来从浏览器调用 Asana API。从浏览器发出的 XDR 请求都以调用 OPTIONS 以获取 Access-Control-* 标头开始,但 Asana 服务器似乎没有响应它们:
Request URL:https://app.asana.com/api/1.0/users?opt_pretty=true&opt_fields=name,email
Request Method:OPTIONS
Status Code:404 Object Not Found
Request Headers:
Accept:*/*
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3
Accept-Encoding:gzip,deflate,sdch
Accept-Language:fr-FR,fr;q=0.8,en-US;q=0.6,en;q=0.4
Access-Control-Request-Headers:origin, authorization, accept
Access-Control-Request-Method:GET
Connection:keep-alive
Host:app.asana.com
Origin:null
User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/536.11 (KHTML, like Gecko) Chrome/20.0.1129.0 Safari/536.11
Query String Parameters:
opt_pretty:true
opt_fields:name,email
Response Headers:
Content-Length:82
Content-Type:application/json
Date:Sat, 12 May 2012 22:23:19 GMT
Server:nginx/0.7.67
...
响应标头应包含以下内容:
Access-Control-Allow-Headers: Accept, Authorization, Content-Type
Access-Control-Allow-Methods: GET,PUT,POST,DELETE
Access-Control-Allow-Origin: *
或者在请求 API 时我遗漏了什么?
