Question

我有通过http：

上传文件的代码

FileInputStream fileInputStream = new FileInputStream(selectedFile);
            URL url = new URL(SERVER_URL);
            connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);//Allow Inputs
            connection.setDoOutput(true);//Allow Outputs
            connection.setUseCaches(false);//Don't use a cached Copy
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("ENCTYPE", "multipart/form-data");
            connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
            connection.setRequestProperty("uploaded_file",selectedFilePath);



            //creating new dataoutputstream
            dataOutputStream = new DataOutputStream(connection.getOutputStream());

            //writing bytes to data outputstream
            dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
            dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
                    + selectedFilePath + "\"" + lineEnd);

            dataOutputStream.writeBytes(lineEnd);

但我需要发送用户信息，如邮件/密码

我尝试过这种方式，但只上传文件，用户信息为空：

FileInputStream fileInputStream = new FileInputStream(selectedFile);
            URL url = new URL(SERVER_URL);
            connection = (HttpURLConnection) url.openConnection();
            connection.setDoInput(true);//Allow Inputs
            connection.setDoOutput(true);//Allow Outputs
            connection.setUseCaches(false);//Don't use a cached Copy
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Connection", "Keep-Alive");
            connection.setRequestProperty("ENCTYPE", "multipart/form-data");
            connection.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
            connection.setRequestProperty("uploaded_file",selectedFilePath);
            connection.setRequestProperty("user",user);

我添加了connection.setRequestProperty（“user”，user）;但在服务器端，它是空的

$user = $_POST['user'];

我如何在同一个httpurlconnection中发送文件和用户信息？

Answer 1

我解决了这个代码：

 dataOutputStream.writeBytes(twoHyphens + boundary + lineEnd);
            dataOutputStream.writeBytes("Content-Disposition: form-data; name=\"myparameter\"" + lineEnd);
            dataOutputStream.writeBytes(lineEnd);
            dataOutputStream.writeBytes(myvalue);

其中myparameter是参数，myvalue是参数

的值

Android通过HttpURLConnection发送HTTP文件参数和非文件
