我在使用Multipart上传将图像上传到Restful服务时遇到问题
我正在使用OKHttp示例中的Recipe。
由于某种原因，上传没有找到图像。
我验证文件是否有效（我可以输出有关文件的信息，并查看是否找到它），但当上传应该发生时，我收到一个错误，告诉找不到文件。
有人能看出我做错了什么吗？
这是我的代码：
@Override
protected Boolean doInBackground(Void... params) {
Bitmap bmp = attachment.getBitmap(getActivity(), ATTACHMENT_IMG_SIZE);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 70, bos);
File file = new File(attachment.getFilename(getActivity()));
try {
Log.d("MSW", "The file Canonical Path: " + file.getCanonicalPath());
Log.d("MSW", "The file name: " + file.getName());
Log.d("MSW", "The file Path: " + file.getPath());
} catch (IOException e) {
e.printStackTrace();
}
OkHttpClient client = new OkHttpClient();
HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor();
loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
client.networkInterceptors().add(loggingInterceptor);
RequestBody requestBody = new MultipartBuilder()
.type(MultipartBuilder.FORM)
.addFormDataPart("method_name", "upload_attach")
.addFormDataPart("forum_id", getArguments().getString(ARG_FORUM_ID))
.addFormDataPart("attachment[]", file.getName(), RequestBody.create(MediaType.parse("image/png"), file))
.build();
Request request = new Request.Builder()
.url(AppConfig.MOBIQUO_ATTACH_URL)
.post(requestBody)
.build();
String respStr = "";
Log.d("MSW", "BEFORE ---: ");
try {
Log.d("MSW", "BEFORE RESP: ");
Response response = client.newCall(request).execute();
if (!response.isSuccessful()) {
Log.d("MSW", "Response UNSuccessful: ");
throw new IOException("Unexpected code " + response);
} else {
Log.d("MSW", "Response Successful: " + response.body().string());
respStr = response.body().string();
System.out.println(response.body().string());
}
} catch (IOException e) {
Log.d("MSW", "Exception: " + e);
e.printStackTrace();
}
Log.d("MSW", "Response is: " + respStr);
return parseResponse(respStr);
}
这是错误消息：

该文件不存在。您可以通过使用FileInputStream读取它的第一个字节来确认这一点。
文件规范路径：/4970.jpg
对于任何普通的Android设备来说，这都是不可能的文件路径，因为根目录不仅永远不可写，而且是应用程序，而且一般来说是只读文件系统。
这表示您的函数是用无效参数调用的，需要在调用方中解决此问题。
