Hi Everyone I want to send Formdata which includes some strings and an image file using react native expo to node server and mongo db can someone explain how can I do this using react native expo I have tried several methods but I am not successful however I am able to send data using backend but I don't know how to send using React native expo?

CodePudding user response：

one of the libraries you can use to send data from react native is Axios you can install it via :

npm i axios

and here is how you can send data with that :

You can post axios data by using FormData() like:

var bodyFormData = new FormData();

And then add the fields to the form you want to send in case you can use append:

bodyFormData.append('userName', 'Fred');

If you are uploading images, you may want to use .append

bodyFormData.append('image', imageFile); 

And then you can use axios post method (You can amend it accordingly)

axios({
  method: "post",
  url: "myurl",
  data: bodyFormData,
  headers: { "Content-Type": "multipart/form-data" },
})
  .then(function (response) {
    //handle success
    console.log(response);
  })
  .catch(function (response) {
    //handle error
    console.log(response);
  });
