Question

我正在使用HttpClient使用以下代码发送POST多部分请求

                String apiUrl = API_URL_DEV;
                String name = API_USER_DEV;
                String password = API_PASSWORD_DEV;
                String authString = name + ":" + password;
                String encoding = Base64.getEncoder().encodeToString(authString.getBytes());
                apiUrl = "https://<servicenow host>/api/now/attachment/upload";

                try {
                    Header header = new BasicHeader(HttpHeaders.CONTENT_TYPE, "multipart/form-data");
                    Header header2 = new BasicHeader(HttpHeaders.ACCEPT, "application/json");
                    Header header3 = new BasicHeader(HttpHeaders.AUTHORIZATION, "Basic " + encoding);

                List<Header> headers = new ArrayList<Header>();
                headers.add(header);
                headers.add(header2);
                headers.add(header3);

                HttpHost proxy = new HttpHost("xxxx", 8080, "http");

                CloseableHttpClient client = HttpClientBuilder.create()
                        .setDefaultHeaders(headers)
                        .setProxy(proxy)
                        .build();
                HttpPost post = new HttpPost(apiUrl);
                String textFileName = "C:/Heena_Code/Test.xlsx";

                File file = new File(textFileName);
                MultipartEntityBuilder builder = MultipartEntityBuilder.create();
                builder.setMode(HttpMultipartMode.BROWSER_COMPATIBLE);

                FileBody fileBody = new FileBody(file, ContentType.DEFAULT_BINARY);
                StringBody stringBody1 = new StringBody("change_request", ContentType.MULTIPART_FORM_DATA);
                StringBody stringBody2 = new StringBody("a81c6a1ddb2948d04af824f4059619a9", ContentType.MULTIPART_FORM_DATA);

                builder.addPart("table_name", stringBody1);
                builder.addPart("table_sys_id", stringBody2);
                builder.addPart("uploadFile", fileBody);
                HttpEntity entity = builder.build();

                post.setEntity(entity);

                // Execute HTTP Post Request
                ResponseHandler<String> responseHandler = new BasicResponseHandler();
                String responseBody = client.execute(post, responseHandler); -----> exception here
                System.out.println(responseBody);

获取异常

我改变了方法，并使用MultiPartUtility类通过HTTPUrlConnection触发请求，以文本/纯格式传递了两个表单字段，并以应用程序/八位字节流格式和二进制编码传递了文件
