Android cliente analizar los datos de formulario de multipart a non ascii

¿Puede explicar por qué el cliente de android analiza datos multiparform para no chat ASCII. Mientras que la carga del archivo que trabaja bueno usando el cartero aquí es mi código de app.js

var multipart = require('connect-multiparty'); var apiRoutes = require('./routes/apiRoutes'); app.set('views', path.join(__dirname, 'views')); app.use(logger('dev')); app.use(bodyParser.json({limit: '50mb'})); app.use(bodyParser.urlencoded([{extended: false},{ uploadDir:path.join(__dirname, 'uploads') }, {parameterLimit:100000}, {limit: '50mb'}])); app.use(cookieParser()); app.use(express.static(path.join(__dirname, 'public'))); app.use(express.static(path.join(__dirname, 'uploads'))); app.use(multipart()); app.use(apiRoutes); 

Y el punto apiRoutes mi función de carga contienen simple impresión req param.using postman que funciona bien

• Cordova android build falla inmediatamente
• Conexión de socket - Java añade bytes
• No hay certificado de pares Excepción - Volley y Android con certificado auto-firmado
• ¿No puede ejecutar node.js en el teléfono Android?
• Cordova Android Upgrade - No se puede encontrar el módulo 'lodash / object / assign' Error

 console.log("mediaChat called", req.body, req.files); 

respuesta

 mediaChat called { apiKey: '123' } { media: { fieldName: 'media', originalFilename: 'default.png', path: '/tmp/KFnwsKGp-f4woTaBH6aPR-qa.png', headers: { 'content-disposition': 'form-data; name="media"; filename="default.png"', 'content-type': 'image/png' }, size: 716, name: 'default.png', type: 'image/png' } } 

Aquí está mi código del cliente del androide (nota este código que trabaja el archivo con php $ _FILE pero no que trabaja con expreso)

Usando android este espectáculo con cable de respuesta como a continuación

I también intentó multer y otro multipart manejador pero notando trabajos. Por favor, ayúdame a salir de este infierno

 BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "UTF-8")); 

 // create a buffer of maximum size bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = new byte[bufferSize]; // read file and write it into form... bytesRead = fileInputStream.read(buffer, 0, bufferSize); while (bytesRead > 0) { dos.write(buffer, 0, bufferSize); bytesAvailable = fileInputStream.available(); bufferSize = Math.min(bytesAvailable, maxBufferSize); buffer = null; buffer = new byte[bufferSize]; bytesRead = fileInputStream.read(buffer, 0, bufferSize); }
