CORS

接口支持“跨域資源共享”（Cross Origin Resource Sharing, CORS），這里和這里和這份中文資料有一些指導(dǎo)性的資料。

簡(jiǎn)單示例：

$ curl -i https://api.example.com -H "Origin: http://example.com"
HTTP/1.1 302 Found

$ curl -i https://api.example.com -H "Origin: http://example.com"
HTTP/1.1 302 Found
Access-Control-Allow-Origin: *
Access-Control-Expose-Headers: ETag, Link, X-Total-Count
Access-Control-Allow-Credentials: true

預(yù)檢請(qǐng)求的響應(yīng)示例：

$ curl -i https://api.example.com -H "Origin: http://example.com" -X OPTIONS
HTTP/1.1 302 Found
Access-Control-Allow-Origin: *
Access-Control-Allow-Headers: Authorization, Content-Type, If-Match, If-Modified-Since, If-None-Match, If-Unmodified-Since, X-Requested-With
Access-Control-Allow-Methods: GET, POST, PATCH, PUT, DELETE
Access-Control-Expose-Headers: ETag, Link, X-Total-Count
Access-Control-Max-Age: 86400
Access-Control-Allow-Credentials: true

JSON-P

如果在任何?GET?請(qǐng)求中帶有參數(shù)?callback?，且值為非空字符串，那么接口將返回如下格式的數(shù)據(jù)

$ curl http://api.example.com/#{RESOURCE_URI}?callback=foo

foo({
  "meta": {
    "status": 200,
    "X-Total-Count": 542,
    "Link": [
      {"href": "http://api.example.com/#{RESOURCE_URI}?cursor=0&count=100", "rel": "first"},
      {"href": "http://api.example.com/#{RESOURCE_URI}?cursor=90&count=100", "rel": "prev"},
      {"href": "http://api.example.com/#{RESOURCE_URI}?cursor=120&count=100", "rel": "next"},
      {"href": "http://api.example.com/#{RESOURCE_URI}?cursor=200&count=100", "rel": "last"}
    ]
  },
  "data": // data
})
