How to pass value from a react native app to a node js backend

Question

I'm trying to pass datas to my back-end Node js server with my react native app. And for that i'm using axios.

  onTrigger = () => {
    const params = JSON.stringify({
      "username": "Name",
      "password": "Pass",
    });
    axios.post('http://192.168.1.36:8080/api/signin',params)
    .then(function (response) {
      this.props.navigation.navigate('Principal')
    })
    .catch(function (error) {
      console.log(error);
    });
  }

But it's not doing nothing. My server is not detecting nothing.

But when i'm trying with postman with the same body and the same datas, it's working.

With Postman, i have a reaction from my server

I would like to know if anyone have an idea why my axios is not working but if i'm doing the same in postman, it's working.

          },
          data : params
        };
        
        axios(config)

        });

Please try this.

const apiClient = axios.create({ baseURL: 'http://192.168.1.36:8080/, timeout: 10000, headers: {'Content-Type': 'application/json'}, });

const params = { username: "Name", password: "Pass", });

apiClient.post('api/signin',params).then(() => {})
