Support for blobs

[ma-pe]

Thanks for open sourcing your library! :)

Blob-support for react-native's fetch was introduced in 0.54:

https://github.com/facebook/react-native/pull/11417 https://github.com/facebook/react-native/pull/11573

Blobs doesn't seem to work with your library though:

var blob = new Blob();
pinnedFetch('https://jsonplaceholder.typicode.com/posts/1', {
  method: 'PUT',
  body: blob,
  headers: {
    'Content-Type': 'application/octet-stream',
  },
  sslPinning: {[
    "my.certificate"
  ]},
})
.then(response => response.json())
.then(json => console.warn(json));

Leads to:

Exception '-[__NSDictionaryM dataUsingEncoding:]: unrecognized selector sent to instance 0x1c4239de0' was thrown while invoking fetch on target RNSslPinning with params (
    "https://jsonplaceholder.typicode.com/posts/1",
        {
        body =         {
            "_data" =             {
                blobId = "cc129bc0-f470-405f-80f8-2c115b404e76";
                lastModified = 1535620344891;
                offset = 0;
                size = 0;
                type = "";
            };
        };
        headers =         {
            "Content-Type" = "application/octet-stream";
        };
        method = PUT;
        sslPinning =         {
            certs =             (
                "my.certificate"
            );
        };
    },
    137
)

I need ssl pinning for all my request but haven't found a library featuring blob PUTs.

Any thoughts on how to support this?

[ajaysaini-sgvu]

Any update on this ?

[brunnorech]

Any update on this ? or other alternative ? other library ?

[canhtran10]

Any solution for this??? :( it seems to work fine for Android. But with Ios, the exception thrown when i try to import fetch function: import {fetch} from 'react-native-ssl-pinning';

@canhtran10 can you show me an example of a request ? so i can check it/

[canhtran10]

HI @MaxToyberman thanks for your support: Send to you the log & request:

@canhtran10 how is it related to Blobs ?

[canhtran10]

@MaxToyberman, ah sorry :), I don't know this problem related to the Blobs or not, but the error message was the same.

[MaxToyberman]

@canhtran10 remove the body: null, in GET you shouldn't add body

[MaxToyberman]

@ma-pe @ajaysaini-sgvu @brunnorech can you provide some example ? how do you expect to receive the data in your backend ?

[soufian97]

Hi, I've also this problem you can find below what I'm expecting from my back end :

[xhirazi]

Passing any type other than string in body causing me this error.

Any solution?

[WassimHakim]

Facing the same issue. Anyone managed to solve it?

[xhirazi]

@WassimHakim try JSON.stringify(body)

[haripatel-mobio]

Any update on this ? We use this react-native-ssl-pinning -> fetch, From API getting normal data response instead of blob response.

fetch(API_URL)
.then((response) => {
    return response.blob()
})
.catch(error => {
    console.log(`error: ${error}`);
})

Require to get blob response, From server side return file(PDF, Image, etc.) object in api response.
