React Native ssl pinning and cookies handling based on okhttp3 on (Android). and AFNetworking on (iOS)

react-native-ssl-pinning's Issues

Unclear error message when certificate is expired or invalid

When I pin invalid/expired certificate in the fetch I see the error message as below :

'' java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. ''
which is not providing proper details on why the certificate pinning failed. It would be great if a more proper message will be shown...

Support for Self-Signed Cert?

Will there be support for api endpoint which is self-signed?

IOS Certificate Pinning - Error object cannot be nil

Hi @MaxToyberman ,

I need yor help.
I followed the guide and it works fine with android. However, it doesn't works with IOS. I tried GET and POST request, but I got this native error

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

I try to debug then it's stopped here

I don't know what's missing here

My config is RN 0.58.3 and react-native-ssl-pinning 1.4.0

IOS public key pinning - Error: cancelled

I followed the guide and it works fine with android. However, it doesn't works with IOS. I tried GET and POST request, but I always get "Cancelled" as error.
I even tried to request other domains, but as said, nothing works.
My config is RN 0.61.5 and react-native-ssl-pinning ^1.4.0

iOS GET request - Error: Cancelled

Hi,

I am trying to make a secure GET request to Google Maps API but I keep getting very ambiguous error - error: cancelled.

My configuration is as follows:

fetch(URL, {
            method: 'GET',
            timeoutInterval: 10000,
            sslPinning: {
                certs: ['cert_google']
            }
        }

I have generated a certificate following the recommended steps and linked it to the XCode project.

Any ideas what is going wrong?

Thanks in advance.

Able to support native side?

Hi, I have a react native project which has API calls in React Native side and as well in native side (Java and Swift). Is it possible to support the native side?

SSL Context is not initialized

I got this error and i can't solve this.
I'm using react-native-cli: 2.0.1, react-native: 0.59.9

how to test if the solution is working

I followed the guide and added the solution for iOS app. How do I test the solution to make sure it works? I tried to replace the certificate with a different one and that does not seem to make any difference.
Our server is a virtual host and I had to use "openssl s_client -showcerts -servername <server_hostname> -connect <server_hostname>:443" to get the certificate. Does the solution works for vhost?

Expo project - issue

Hello,

I'm facing with issue which was already mention here #46 #19, it is failing on :
Cannot read property 'fetch' of undefined node_modules/react-native-ssl-pinning/index.js:8:17 in fetch
On line where is loading NativeModules => const { RNSslPinning } = NativeModules;

The main concern from me is next:

Is it possible to this library working with expo project ? because of that linking and those stuff ?

NOTE:
I'm using Expo SDK 37.0.1 which is using RN 0.61
Thanks in advice!

iOS - Headers aren't applied if body field is not specified

In the objective C code, headers are only applied if the body field exists:

if ([obj objectForKey:@"body"]) {
    NSDictionary * body = obj[@"body"];
    
    // this is a multipart form data request
    if([body isKindOfClass:[NSDictionary class]] && [body objectForKey:@"formData"]){
        // post multipart
        NSDictionary * formData = body[@"formData"];
        [self performMultipartRequest:manager obj:obj url:url request:request callback:callback formData:formData];
    }
    else {
          [self setHeaders:obj request:request];
        // post a string
        NSData *data = [obj[@"body"] dataUsingEncoding:NSUTF8StringEncoding];
        [request setHTTPBody:data];
        
        //TODO: if no body
    }
    
}
[self performRequest:manager request:request callback:callback ];

This means for GET requests, you have to explicitly set body: ''. Took me a few hours to figure out what was going on - our API throwing back auth errors because the Authorization header was left off the request. Headers should still be applied if body field is omitted. Or this should at least be documented.

iOS post requests get wrong header

Edit: never mind

[__NSArrayM insertObject:atIndex:]: object cannot be nil

in iOS I am getting this issue and app crashed due to this thread

How to use react native ssl pinning with axios library

How to use react native ssl pinning with axios library

Unhandled exception when native module returns error string

Currently the library throws an unhandled exception for attempting to assign properties to an error string returned from native modules.

When I patched for my own use, I simply wrapped the assignments in a conditional checking the typeof data:

But allowing the function to return the error string directly violates the TypeScript response type

    interface Response {
        bodyString: string;
        headers: Header;
        status: number;
        url: string;
        json: () => Promise<{ [key: string]: any}>;
        text: () => Promise<string>;
    }

export declare function fetch(url: string, options: ReactNativeSSLPinning.Options): Promise<ReactNativeSSLPinning.Response>;

Would you prefer that the native module error string be incorporated into the existing expected response object, or that the types be modified to conditionally return a Promise-wrapped error string instead?

Error cancelled on ios

I follow the steps for ios key pinning as they are listed and i keep getting error cancelled in catch of react native code. I should put the .cer file in root folder of app right?

RNSslPinning undefined using RN 0.60.3

Hello,

Using RN 0.60.3, I am seeing the below error:

TypeError: Cannot read property 'fetch' of undefined
Contained within index.js:8:17

Examining the index.js for this library and troubleshooting, it appears the object RNSslPinning is null:
`import { NativeModules } from 'react-native';
import Q from 'q'

const { RNSslPinning } = NativeModules;
`

Linking of libraries is now handled by default in RN 0.60.+, could this be related to that?

I need to implement Certificate Pinning in my react native which uses axios for api call

Unable to request using FormData

Hi MaxToyberman, i really need your help how to use formData in your library. when im having a request theres an error with ios when using formData

var photo = {
uri: Platform.OS == "android" ? response.uri : response.uri.replace("file://", ""),
type: "image/png",
name: response.name
}

        var data = new FormData();
        data.append('token', this.props.token);
        data.append('id', this.props.Credentials.id);
        data.append('image', photo);

body = {
formData: JSON.stringy(data)
}

is there any wrong with these?

Fetch doesn't happen when body passed (POST Request)

fetch isn't run when POST method passed with body parameter. See my request below, if body is included I get the output:

when body isn't passed we enter the catch as my server responds with a 400 (missing the parameters. Output:

My fetch request:

        let bodyObject = {

          fieldsToUpdate: fieldsToUpdate
        }
        console.log("here-----------------------------")
        fetch(`${Config.API_URL}/users/update`, {
          method: "POST" ,
          
          timeoutInterval: 10000, // millisecondsbody: 
          body: bodyObject,

HI @MaxToyberman thanks for build this repo and sharing with the community can you please confirm license grants? Hopefully MIT?

pkPinning doesn't exist in the Options object.

The pkPinning property in the Options object hasn't been added yet so there is an error when setting the options from TypeScript.

Multipart request (FormData) not work in iOS

with Android it's working perfectly, i don't understand why it's not working in iOS (all ios version), don't have any parameters transfer to the API server:

THE LOG REQUEST IN SERVER:

Files: "" ; group receipents: "" ; User receipients: ""

The CODE:

const localUploadAttachment = async (url, a, message) => {
    let formData = new FormData();
    let dataObj = {
        name: a.name,
        type: 'image/jpg',
        uri: a.uri
    };
    formData.append('files', dataObj); // i tested with "file" parametter but its still not work
    formData.append('groupRecipients', JSON.stringify(message.GroupRecipients));

How to handle POST Query using FormData

I tried using FormData given in repository but did not worked for me. I was not getting any response , means no call in then or catch .

I want to use

const data = new FormData();
data.append("query", queryString);

error on android at application startup - first few requests

java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

Support for blobs

Thanks for open sourcing your library! :)

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

facebook/react-native#11417
facebook/react-native#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?

Linking - Uncomplete on Android RN 0.59.8

When using react-native link the project cannot sync successfully because a maven dependency is missing from project level gradle:

Dependency needed by com.github.franmontiel:PersistentCookieJar:v1.0.1

repositories { maven { url "https://jitpack.io" } }

Needs fixing.
