Android utf-8 coding

[toearth]

The js communicates with android native use utf-8 code, when I request a binary text from server, the response type is not blob, it coded to utf-8 string. And iOS use base64 code, it works well.

Hi @windhost , could you let me know what's the Content-Type of response and how you send your request ? Thank you 👍

'Content-Type': 'application/octet-stream',
This is my Content-Type.

[toearth]

respInfo:Object
  headers:Object
    Access - Control - Allow - Headers: "Origin, X-Requested-With, Content-Type, Accept"
    Access - Control - Allow - Origin: "*"
    Access - Control - Expose - Headers: "Refresh-Token"
    Content - Length: "47"
    Content - Type: "application/octet-stream"
    Date: "Fri, 09 Sep 2016 02:48:10 GMT"
    Refresh - Token: "..4VJPjD2iKfpM-"
  __proto__ : Object
  redirects : Array[1]
  respType : ""
  rnfbEncode : "utf8"
  state : "2"
  status : 200
  taskId : "a329d05a-34d8-4291-b86e-2099d416de77"
  timeout : false

Thank you for your update, but I also can't get a blob.

This is in iOS

  respInfo: 
   { status: '200',
     state: '2',
     taskId: '62472c13-2848-4739-b211-f7f82b301944',
     headers: 
      { 'Content-Type': 'application/octet-stream',
        'Access-Control-Expose-Headers': 'Refresh-Token',
        Date: 'Fri, 09 Sep 2016 02:58:30 GMT',
        'Access-Control-Allow-Headers': 'Origin, X-Requested-With, Content-Type, Accept',
        'Refresh-Token': '',
        'Content-Length': '47',
        'Access-Control-Allow-Origin': '*' },
     respType: 'blob',
     timeout: false,
     rnfbEncode: 'base64' },

@windhost , thanks for the detailed information that's really helpful, basically our network module will try to decode response data as UTF8 string, if it failed, encode the data using BASE64 encoding. Looks like this process success on Android but failed on IOS, as such it result in inconsistent behavior.

To solve this problem, I'm planning to add an extra option to fetch so that the response data will always encoded as BASE64 string, so that you can use it this way

RNFetchBlob.fetch('GET', 'http://example.com/myblob', 
{
  // extra header
  'RNFB-Response' : 'base64'                                                                                                                                                      
})
.then((res) => {
    res.base64()
})

I'll update the status in this thread once it's done 😄

You have solved this problems, that help me a lot. Thank you a thousand! I'm waiting for your update.

@windhost , I've published 0.9.5-beta.2 which allows you force response format.

RNFetchBlob.fetch('GET', 'http://example.com/myblob', 
{
  // extra header
  'RNFB-Response' : 'base64'                                                                                                                                                      
})
.then((res) => {
    res.text() // should be base64 encoded string
})

Please try upgrade to this version, see if it solves the problem, thank you 😄

[toearth]

OK, I will do this.

[toearth]

It works on android. Thank you for you reply!
respType:"" rnfbEncode:"base64" state:"2" status:200

Great ! 👍 Nice to know it works 😄
