我正在开发一个反应本机应用程序,并试图将存储在设备上的图像上传到S3。我知道图像的路径,但是当我尝试上传映像时,S3返回不支持的文件错误或将文件上传到其名称,但该文件仅包含文件路径字符串。
我正在使用AWS-amplify建立这些连接。
这是我使用的代码块:
const file = `${RNFetchBlob.fs.dirs.DocumentDir}/${localFilePath}`;
Storage.put("exampleFolder/" + userId + ".jpeg", file)
.then(result => console.log(result))
.catch(err => console.log(err))
非常感谢
在AWS-Mobile-Reacter-native-native-starter repo中有一个很好的例子。您只需要读取文件,然后就可以上传。
return files.readFile(imagePath)
.then(buffer => Storage.put(key, buffer, { level: 'private', contentType: result.type }))
.then(fileInfo => ({ key: fileInfo.key }))
.then(x => console.log('SAVED', x) || x);
读取他们使用react-native-fetch-blob
的文件:
readFile(filePath) {
return RNFetchBlob.fs.readFile(filePath, 'base64').then(data => new Buffer(data, 'base64'));
}
您将文本作为文件的内容发送,而不是二进制文件
中的文件下面的类似于下面的hello将在s3文件中存储
Storage.put('test.txt', 'Hello')
.then (result => console.log(result))
.catch(err => console.log(err));
尝试提及contentType,对于您的案例图像/png,如下示例中的文本文件
Storage.put('test.txt', 'Private Content', {
level: 'private',
contentType: 'text/plain'
})
从打击URL中汲取灵感:
