Answer 1

you can try like this for send data to server(POST)

let response = await fetch(
    'http://your_url', {
      method: 'POST',
      headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        username: this.state.name,//data which u want to send
        password: this.state.password,
      })
  });
  let responseText = await response.text();
  if (response.status >= 200 && response.status < 300){
    Alert.alert('Server response', responseText)

  }
  else {
    let error = responseText;
    throw error
    //Alert.alert('Login', error)
  }
} catch(errors) {
  Alert.alert('Login', errors)

  Actions.Documents();
}

Edit: As latest iOS sdk enforces connection to be in https protocol instead of http.you can add an exception to your domain inside info.plist file of the Xcode project.

if you want to allow everything write this inside info.plist

NSAppTransportSecurity

NSExceptionDomains

    yourdomain.com
    
        
        NSIncludesSubdomains
        
        
        NSTemporaryExceptionAllowsInsecureHTTPLoads
        
        
        NSTemporaryExceptionMinimumTLSVersion
        TLSv1.1
