[英]Payload too large error (413) when uploading using JS Fetch API. Works fine via Postman
我有一个分段上传 API,当我通过 Postman 上传文件时,它可以完美运行。 但是,当我通过相同的 API 上传但使用 Fetch API 时,出现 413 错误。
我的JS代码如下 -
async function uploadAudio(formElements) {
const formData = new FormData();
const file = fileUploadField.files[0];
formData.append("file", file);
console.log("Name: " + file.name); // Prints the correct file name
console.log("Size: " + file.size); // Prints the correct size (which is < than what is set server side)
const options = {
method: 'POST',
body: formData,
headers: {
'Content-Type': 'multipart/form-data',
'Accept': 'application/json',
'Authorization': 'Bearer ' + authTokenArr[0]
}
};
const response = await fetch(base_url + "/audio/file", options);
const data = await response.json();
if (response.ok) {
handleSuccess(data);
} else {
handleFail(data);
}
}
application.properties
文件 -
# max file size
spring.servlet.multipart.max-file-size=10MB
# max request size
spring.servlet.multipart.max-request-size=10MB
REST 控制器 -
@PostMapping("file", produces = [ProduceTypes.JSON])
fun uploadAudio(@RequestParam("file") file: MultipartFile,
@RequestHeader (name="Authorization") token: String): ResponseEntity<MutableMap<String, Any>> {
val user: User = userService.getUserDetailsByToken(token)
val body: MutableMap<String, Any> = LinkedHashMap()
body["status"] = ApiStatus.UPLOADED
body["fileId"] = podcastFileService.uploadFileToB2(user, file)
return ResponseEntity(body, HttpStatus.CREATED)
}
这是我的服务器端日志 -

当 API 通过 Postman 正常工作时,甚至使用带有非 REST 控制器的mustache
模板上传时,为什么会出现大小问题。
结果是'Content-Type': 'multipart/form-data'
是问题所在。 当我删除它时它起作用了。 @Kostiantyn
