As in the title, I'm trying to upload file to Spring Rest Controller using:
handleOnChange() {
let inputFile = document.getElementById("file-input");
this.file.file = inputFile.files[0];
this.file.filename = inputFile.value;
}
render() {
return (
<div className="file-input">
<input id="file-input" type="file"
onChange={(event) => this.handleOnChange()} />
</div>
);
}
upload() {
let formData = new FormData();
formData.append("file", this.data.file.file, "/D:/temp/test2.xlf");
formData.append("request", JSON.stringify(request));
let reqOptions = {
method: 'POST',
body: formData
}
fetch('http://127.0.0.1:8081/multi-mt-evaluation/report', reqOptions)
.then(response => response.json())
.then(data => console.log(data));
}
But when fetch is called the file is sent as application/octet-stream, is there a simple, or more complicated way to set it as multipart/form-data?
Try specifying the content type by adding it to your request headers:
let reqOptions = {
method: 'POST',
body: formData,
headers: {
'Content-Type': 'multipart/form-data',
},
}
