我寻求专家的帮助，我是 React Native 的新手并且遇到了这样的问题。 enter image description here 尝试使用 react-native-image-crop-picker 通过单击按钮以这种方式发送文件 我已经在 Next js 上将文件发送到服务器，一切正常，但现在我需要制作一个移动版本，但它没有按我预期的那样工作。
import { useMutation } from '@apollo/client';
import React,{ useCallback,useEffect,useState } from 'react';
import {
Image,SafeAreaView,ScrollView,StatusBar,StyleSheet,View,} from 'react-native';
import { Button } from 'react-native-elements';
import Icon from 'react-native-vector-icons/FontAwesome';
import ImagePicker from "react-native-image-crop-picker"
import { ReactNativeFile } from 'apollo-upload-client';
import { gql } from "@apollo/client";
export const mutationSendPhotoForProcessing = gql`
mutation SendPhotoForProcessing($file: Upload!){
send_photo_for_processing(file: $file)
}
`
const Home = () => {
const [SendPhoto] = useMutation(mutationSendPhotoForProcessing);
const onButtonPress = async () => {
let file = await ImagePicker.openPicker({
cropping: true
});
const { data } = await SendPhoto({
variables: {
file: new ReactNativeFile({
name: 'a.jpg',type: 'image/jpg',uri: file.path,}),}
});
};
return (
<SafeAreaView>
<StatusBar barStyle={'dark-content'} />
<ScrollView>
<View>
<Button
onPress={() => alert()}
icon={
<Icon name="upload" color={"white"} size={20} />
}
/>
<Button
onPress={() => onButtonPress()}
title="Upload image"
/>
</View>
</ScrollView>
</SafeAreaView>
);
};
const styles = StyleSheet.create({
sectionContainer: {
marginTop: 32,paddingHorizontal: 24,},});
export default Home;
