android - 如何通过多部分实体方法将值从应用程序传递到 api 端？

Question

我想将值从应用程序端传递到 api。在此 api 调用中传递图像、名字、电子邮件、电话和位置。在 Debug模式下，检查值不会被传递。

代码下方

 File file = null;
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);
            httpPost.setHeader(HTTP.CONTENT_TYPE, "application/x-www-form-urlencoded");
            httpPost.addHeader("X-COMPANY", currentcity);
            MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            if (imagepath != null) {
                file = new File(imagepath);
                entity.addPart("pic", new FileBody(file));
            }
            entity.addPart("firstname", new StringBody(firstName, ContentType.TEXT_PLAIN));
            entity.addPart("email", new StringBody(email, ContentType.TEXT_PLAIN));
            entity.addPart("telephone", new StringBody(phonenumber, ContentType.TEXT_PLAIN));
            entity.addPart("location", new StringBody(locaity, ContentType.TEXT_PLAIN));
            httpPost.setEntity(entity);
            Log.d("URL Request: ", url.toString());
            HttpResponse httpResponse = httpClient.execute(httpPost);

我认为你没有正确传递标题。使用下面的代码-

HttpURLConnection httpcon = (HttpURLConnection) ((new URL(strUrl).openConnection()));
            httpcon.setDoOutput(true);
            httpcon.setRequestProperty("Content-Type-", "multipart/form-data");
            httpcon.setRequestMethod("POST");

 MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
            if (imagepath != null) {
                file = new File(imagepath);
                entity.addPart("pic", new FileBody(file));
            }
            entity.addPart("firstname", new StringBody(firstName, ContentType.TEXT_PLAIN));
            entity.addPart("email", new StringBody(email, ContentType.TEXT_PLAIN));
            entity.addPart("telephone", new StringBody(phonenumber, ContentType.TEXT_PLAIN));
            entity.addPart("location", new StringBody(locaity, ContentType.TEXT_PLAIN));

            httpcon.addRequestProperty(entity.getContentType().getName(), entity.getContentType().getValue());

            httpcon.setUseCaches(false);
            httpcon.setDoInput(true);
            httpcon.setDoOutput(true);
            httpcon.connect();

             OutputStream os = httpcon.getOutputStream();
                entity.writeTo(httpcon.getOutputStream());
                os.close();
                httpcon.connect();

            int responseCode = httpcon.getResponseCode();

            if(responseCode == 200)
            {
                InputStream inputStream = new BufferedInputStream(httpcon.getInputStream());
                InputStreamReader inputStreamReader = new InputStreamReader(
                        inputStream);

                BufferedReader bufferedReader = new BufferedReader(
                        inputStreamReader);

                StringBuilder stringBuilder = new StringBuilder();

                String bufferedStrChunk = null;

                while ((bufferedStrChunk = bufferedReader.readLine()) != null) {
                    stringBuilder.append(bufferedStrChunk);
                }

                return stringBuilder.toString();

            }
