我正在尝试使用以下功能上传图像,但一切正常,只是我想在后期发送图像,而当我尝试使图像什么也没得到时
这是针对通话API
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
timer1s();
handler.postDelayed(this, TimerConstants.ONE_SECOND);
}
}, TimerConstants.ONE_SECOND);
tools.lockScreenOrientation(this);
}
我正在传递到服务器的文件是:
Future getUploadImg(access_token,File _image) async {
print("Image: $_image");
String apiUrl = '$_apiUrl/user/upload-profile-image';
final length = await _image.length();
final request = new http.MultipartRequest('POST', Uri.parse(apiUrl));
request.headers['Accesstoken'] = "Bearer $access_token";
request.files.add(new http.MultipartFile('imagefile',_image.openRead(), length));
http.Response response = await http.Response.fromStream(await request.send());
print("Result: ${response.body}");
return json.decode(response.body);
}

我终于得到了结果,如果有人需要帮助,我们需要传递字符串以共享我的工作代码以进行图像共享
fun bind(myCell: MyEntity?) {
myViewModel.myLiveData.observe(this, Observer {
// Buala!! Check if it is the cell you want to change and update it.
if (it != null && myCell != null && it.id == myCell.id) {
updateCell(it)
}
})
}

为了避免以下问题:
您需要在标题中添加正确的参数。
就我而言,这些问题发生在上传图片和发送 base64 编码请求时。我通过添加以下“连接”标头解决了这个问题:“保持活动”:
final response = await this.httpClient.put(
url,
encoding: Utf8Codec(),
headers: <String, String>{
'Content-Type': 'application/json; charset=UTF-8',
'Accept': "*/*",
'connection': 'keep-alive',
'Accept-Encoding' : 'gzip, deflate, br',
},
body: body,
);
