React Native Fetch File Upload Error
fetch-api, react-native
Solution
Yes is it possible upload an image only with fetch API.
I was facing the same issue, I solved it with this:
first, please make sure to remove the `file//` at the beginning of the URL, you could do something like this
const fileURL = "file:///Users/juordergonzalezquinonez/Library/Developer/CoreSimulator/Devices/046E9C13-5D5D-4463-82DD-256501874EBF/data/Containers/Data/Application/839C5E04-46BB-4F9B-BF53-3FDFF639F340/tmp/react-native-image-crop-picker/C07E6B9E-3113-41C2-AD80-A768DF33C263.jpg";
const cleanURL = fileURL.replace("file://", "");
then in the fetch request, make sure that your headers must be like this:
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data;'
},
Problem
I am trying to use fetch to upload an image file to my server. Here is my code that I am using: ``` var formData = new FormData(); formData.append('photo', {uri: './tempImageStore/image.jpg', name: 'photo', type: 'image/jpg'}); ``` and ``` <Button onPress={() => fetch('http://localhost:8000/upload', { method: 'POST', headers: { "Accept": "multipart/form-data", "Content-Type": "multipart/form-data" }, body: formData }) } title={'Upload File'} /> ``` However when I run my app and press the `Upload File` button, I get an error saying: I am not sure what I am doing wrong or if this is even the proper way to upload photos to a server.
