我正在使用javascript fetch API使用以下代码查询跨域api:
fetch('https://api.com/search?query="2016"').then(function (response) {
console.log(response.headers.get('Access-Control-Allow-Headers'))
console.log(response.headers.get('Content-Range'))
console.log(response.headers.get('Accept-Range'))
console.log(response.headers.get('Date'))
console.log(response.headers.get('Content-Type'))
})
响应标题如下:
Accept-Range:cars 300
Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:Origin, X-Requested-With, Content-Type, Accept, Content-Range, Accept-Range
Access-Control-Allow-Methods:PUT, POST, OPTIONS, GET
Access-Control-Allow-Origin:*
Cache-Control:no-cache
Connection:keep-alive
Content-Range:0-99/1941
Content-Type:application/json
Date:Tue, 12 Jan 2016 12:17:55 GMT
Transfer-Encoding:chunked
唯一奇怪的是,只有" Content-Type"我正在为其他人工作 null :
null
null
null
null
application/json
我需要做些什么来检索那些 null 标题?
