請求正文是一個form-data. 請求正文有一個鍵，image它需要一個檔案（此處為影像檔案）。這是我到目前為止所做的：
final response = await http.MultipartRequest(
'POST', Uri.parse(Constant.baseUrl 'api/patients'))
..headers.addAll({"Authorization": "Bearer $token"})
..fields.addAll({
"first_name": firstName,
"last_name": lastName,
"email": email,
"date_of_birth": dob,
"address": address,
"gender": gender,
"blood_group": bg,
"primary_phone": primaryPhone,
"alt_phone": altPhone
})
..files.add(await http.MultipartFile.fromPath(
'image',
image.path,
));
我在此處附上郵遞員請求正文，以便更好地理解我的問題。最后一個關鍵是我面臨的麻煩。
我想我只是在沒有密鑰的情況下上傳影像檔案。這就是為什么我的請求有效但影像仍未發布的原因。這里的影像檔案是一個 XFile（使用 FLutter 中的 image_picker 庫）。
我也想使用http庫來實作這一點。我知道這是可能的dio。但只是為了這個請求，我不想匯入另一個庫。

uploadTest(FilePickerResult result, String url, docname, formId,
{lastService: false}) async {
print(result);
if (result != null) {
String filename = docname;
final file = result.files.first;
// if (lastService == true) {
filename = docname '.' file.name.split(".")[1];
print("filename is $filename");
// }
var uri = Uri.parse(url);
var stream = http.ByteStream(file.readStream);
var request = http.MultipartRequest('POST', uri);
final mimeType = lookupMimeType(file.name ?? '');
var val1 = {
"customerId": variableMap['customerId'],
"FormId": formId,
"docName": filename
};
final val2 = json.encode(val1);
request.fields['val'] = val2;
var multipartFile = http.MultipartFile(
'myFile',
stream,
file.size,
filename: filename,
contentType: mimeType == null ? null : MediaType.parse(mimeType),
);
request.files.add(multipartFile);
final httpClient = http.Client();
final response = await httpClient.send(request);
if (response.statusCode != 200) {
throw Exception('HTTP ${response.statusCode}');
}
final body = await response.stream.transform(utf8.decoder).join();
print(body);
}
}
// 我發布了我使用的方法..沒有自定義為您的用例。它從 filePicker 執行影像上傳
