关于java模拟post 提交multipart/form-data的问题

[dozhn]

通过fiddler抓包和提交都没有问题：

请求页面：http://103.247.176.245:8081/tool/syllabletag/
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryzM0nS9GIodjxCMih
post参数：

------WebKitFormBoundaryzM0nS9GIodjxCMih
Content-Disposition: form-data; name="csrfmiddlewaretoken"

z6l45zfflLQmzmkM2IYQwfTBSKCVUnOl
------WebKitFormBoundaryzM0nS9GIodjxCMih
Content-Disposition: form-data; name="input_text"

hahhahhahahahah
------WebKitFormBoundaryzM0nS9GIodjxCMih
Content-Disposition: form-data; name="output_text"


------WebKitFormBoundaryzM0nS9GIodjxCMih--

请求头：

请求参数

通过fiddler提交后的结果：

HttpClient httpClient = new DefaultHttpClient();
		HttpPost postRequest = new HttpPost("http://103.247.176.245:8081/tool/syllabletag/");
		MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
		try {
			reqEntity.addPart("csrfmiddlewaretoken", new StringBody(getPageToken()));
			reqEntity.addPart("input_text", new StringBody("hahhahhahahahah"));
			reqEntity.addPart("output_text", new StringBody(""));
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		postRequest.setEntity(reqEntity);
		HttpResponse response;
		try {
			response = httpClient.execute(postRequest);
			BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
			String sResponse;
			StringBuilder s = new StringBuilder();
			while ((sResponse = reader.readLine()) != null) {
				s = s.append(sResponse);
			}
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

我通过httpclient模拟提交页面返回的403

在线等。。。就是通过调用这个请求能够得到分词的效果，不胜感激

java相关板块人就是非常少。还有，too long no see，对不起。

00没人回复，那我回复一下，

String boundary = "----WebKitFormBoundarygmk3KBUQwymfMc8A";
		//请求地址
		String url = "https://url";
		String param = "";
		param +="--"+boundary+"\r\n";
		param += "Content-Disposition: form-data; name=\"account\""+"\r\n\r\n";
		//参数account
		param+= "account"+"\r\n";
		param +="--"+ boundary+"\r\n";
		param += "Content-Disposition: form-data; name=\"password\""+"\r\n\r\n";
		//参数password
		param += "password"+"\r\n";
		param+="--"+boundary+"--";
		//请求头，看情况自己加
		Map<String,String> headMap = new HashMap<>();
		headMap.put("Content-Type", "multipart/form-data; boundary=----WebKitFormBoundarygmk3KBUQwymfMc8A");
		Map<String,Object> reMap = HttpClientUtil.doMultipartFormDataPost(url,param,headMap);

public static Map<String, Object> doMultipartFormDataPost(String url, String param, Map<String, String> headParam) {
		// TODO Auto-generated method stub

		// 创建Httpclient对象
		Map<String,Object> resultMap = new HashMap<>();
		String resultString = "";
		CloseableHttpClient httpClient = HttpClients.createDefault();
		CloseableHttpResponse response = null;
		try {
			// 创建Http Post请求
			HttpPost httpPost = new HttpPost(url);
			// 创建请求内容
			StringEntity entity = new StringEntity(param, ContentType.MULTIPART_FORM_DATA);
			httpPost.setEntity(entity);
			for(String key:headParam.keySet()) {
				httpPost.addHeader(key,headParam.get(key));
			}
			// 执行http请求
			response = httpClient.execute(httpPost);
			resultString = EntityUtils.toString(response.getEntity(), "utf-8");
			Header[] headers =response.getHeaders("Set-Cookie");
			Map<String,String> headMap = new HashMap<>();
			for(int i=0;i<headers.length;i++) {
				headMap.put(headers[i].getElements()[0].getName(), headers[i].getElements()[0].getValue());	
			}
			resultMap.put("headMap", headMap);
			resultMap.put("result", resultString);
		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			try {
				response.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		}

		return resultMap;
