我正在尝试使用BrowserClient (package:http/browser_client.dart)
发送多部分请求。我找到了答案:first和second。但他们都使用HttpRequest
。 BrowserClient可以发布字符串,列表或地图,但我想我应该发送html.FormData。
答案 0 :(得分:3)
感谢@filiph,我发现我们如何从angularDart客户端发送带有文件的多部分请求,可能对某人有用。例如,我们有简单的角度飞镖模板:
<input #fileInput type="file" accept="image/*" name="file">
这是文件上传的简单组件:
class FileComponent implements AfterViewInit {
final Client _http;
@ViewChild("fileInput")
ElementRef cameraInputRef;
HealthApiImpl(this._http);
@override
ngAfterViewInit() {
FileUploadInputElement uploadInput = cameraInputRef.nativeElement;
uploadInput.onChange.listen((e) {
File file = (e.target as dynamic).files[0];
createMultipartFileAndUpload(file);
});
}
void createMultipartFileAndUpload(File file) {
FileReader fileReader = new FileReader();
fileReader.onLoad.listen((e) {
var target = e.target as dynamic;
List<int> result = target.result;
MultipartFile mf = new MultipartFile.fromBytes(
"file",
result,
filename: file.name,
contentType: new MediaType.parse(file.type));
upload(mf);
});
fileReader.readAsArrayBuffer(file);
}
void upload(MultipartFile file) {
var uri = Uri.parse("/uploadUrl");
var request = new MultipartRequest("POST", uri);
request.files.add(file);
var response = await _http.send(request);
if (response.statusCode == 200) {
print("success upload");
}
throw new "upload error";
}
}
