fetch-ie8's Issues

Doesn't work on IE9 when accessing another domain

Tested on v1.5.0. Works fine on IE10+, not in IE9.

fetch("http://example.com/api/test")

Always returns Possible Unhandled Promise Rejection: Error: Access is denied, no outgoing network requests, nothing new in server access.log

The same issue when used latest https://github.com/github/fetch (v7.0.2, officially supports IE10+).
I use Promise polyfill, post here taylorhakes/promise-polyfill#69 if it is its related issue.

cross domain / http to https

does this library support cross domain requests? I didnt see the XDomainRequest object in the code from an initial glance. Is there a reason it couldnt work cross domain and would you accept a pull request for it?

IE8，9，10下请求https出现问题？

控制台报错：SCRIPT5: 拒绝访问

是跨域来着的，换成http没问题

fetch cache ie8

@camsong
I set {cache:'no-store'} in fetch options,but IE8 always load resource from cache（request param is the same,but cookie not. It's a new user）.
I want to get resource from server.
Could you help me with this?

empty plain object cause "unsupported BodyInit type" error

fetch(url,{
    body : {},
    method : 'POST'
})

this code may cause "unsupported BodyInit type" error because of below code from fetch-ie8 source

this._initBody = function(body, options) {
      this._bodyInit = body
      if (typeof body === 'string') {
        this._bodyText = body
      } else if (support.blob && Blob.prototype.isPrototypeOf(body)) {
        this._bodyBlob = body
        this._options = options
      } else if (support.formData && FormData.prototype.isPrototypeOf(body)) {
        this._bodyFormData = body
      } else if (!body) {
        this._bodyText = ''
      } else if (support.arrayBuffer && ArrayBuffer.prototype.isPrototypeOf(body)) {
        // Only support ArrayBuffers for POST method.
        // Receiving ArrayBuffers happens via Blobs, instead.
      } else {
        throw new Error('unsupported BodyInit type')
      }
    }

IE8，IE9 Cross Origin Problem 拒绝访问

因为项目要求兼容ie8，通过各种调整目前页面已基本兼容，但是fetch跨域请求（不需要session和cookie验证）在ie8或者ie9下会报拒绝访问的错误，不知道为何，以下是请求截图和ie8下控制台截图。

Response status 302 怎么处理？

浏览器，自己写的代码里，扑捉不到302的响应。

getOwnPropertyNames is not necessary?

Hi

I think this requires es5-shim and es5-sham is because of getOwnPropertyNames.
A simple for...in can also deal with this scenario.
Not sure why the first commit at github uses this method.
Do you have any idea?

Willing to give a PR

ie8 does not support FileReader, I have got resource from servers with blob, so how to deal with it?thanks

function option(options){
return {
...options,
credentials : 'include'
}
}

function imgFetch(url,options=null){
const optionsConfig = option(optiobs);
return fetch(url,optionConfig)
.then((res)=>{return res.blob()})
.then((res)=>{return URL.createObjectURL(res)})
}
