Question

"No file uploaded or URL provided" when calling ocr.space API

我想知道我们如何将文件上传到服务器，如上面的url所发送的那样，代码在C＃中，但我希望它在Java for android

我的代码是

`final HttpClient httpclient = new DefaultHttpClient();
            final HttpPost httppost = new HttpPost("https://api.ocr.space/parse/image");

            //httppost.addHeader("User-Agent", "Mozilla/5.0");
            //httppost.addHeader("Accept-Language", "en-US,en;q=0.5");
              //con.setRequestMethod("POST");
               // con.setRequestProperty("User-Agent", "Mozilla/5.0");
               // con.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

            final FileBody image = new FileBody(new File(fileName));

            final MultipartEntity reqEntity = new MultipartEntity();
            reqEntity.addPart("isOverlayRequired", new StringBody(Boolean.toString(isOverlayRequired)));
            reqEntity.addPart("language", new StringBody(langCode));
            reqEntity.addPart("apikey", new StringBody(apiKey));
            reqEntity.addPart("file",image);
            httppost.setEntity(reqEntity);

            final HttpResponse response = httpclient.execute(httppost);
            final HttpEntity resEntity = response.getEntity();
            final StringBuilder sb = new StringBuilder();
            if (resEntity != null) {
                final InputStream stream = resEntity.getContent();
                byte bytes[] = new byte[4096];
                int numBytes;
                while ((numBytes=stream.read(bytes))!=-1) {
                    if (numBytes!=0) {
                        sb.append(new String(bytes, 0, numBytes));
                    }
                }
            }

            Log.i("data", sb.toString());`

但它提供异常

javax.net.ssl.SSLException: hostname in certificate didn't match: <api.ocr.space> != <ocr.a9t9.com> OR <ocr.a9t9.com> OR <www.ocr.a9t9.com>

您可以尝试给定的link

但是这个网站提供的例子是uri而不是文件。

试试这个适用于我的代码。

String charset = "UTF-8";
File uploadFile1 = new File(fileName);

String requestURL = "https://api.ocr.space/parse/image";

try {
    MultipartUtility multipart = new MultipartUtility(requestURL, charset);

    multipart.addHeaderField("User-Agent", "Mozilla/5.0");
    multipart.addHeaderField("Accept-Language", "en-US,en;q=0.5");

    multipart.addFormField("apikey", apiKey);
    multipart.addFormField("isOverlayRequired", Boolean.toString(isOverlayRequired));
    multipart.addFormField("language", langCode);
    multipart.addFilePart("file", uploadFile1);


    List<String> response = multipart.finish();

    System.out.println("SERVER REPLIED:");

    for (String line : response) {
        System.out.println(line);
    }
} catch (IOException ex) {
    System.err.println(ex);
}

将文件上传到ocr.space api
