我的项目是上传带有一些参数的图像,音频文件(如描述和日期)。
虽然Google宣布使用HttpURLConnection而不是httpclient。我正在使用HttpURLConnection。
我有一个代码可以将图像和音频上传到服务器文件夹中。
但我发送的描述未在服务器中收到。
像Stackover流程中的许多问题一样。但我没有得到确切的解决方案。
我的Android代码是:
FileInputStream fileInputStream = new FileInputStream(sourceFile_image);
URL url = new URL(upLoadServerUri);
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type","multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);
dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
//adding parameter
String description = ""+"Desceiption about the image";
// Send parameter #name
dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd);
dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
dos.writeBytes("Content-Length: " + description.length() + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(description + lineEnd);
dos.writeBytes(twoHyphens + boundary + lineEnd);
// Send #image
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""+ fileName + "\"" + lineEnd);
dos.writeBytes(lineEnd);
// 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);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
和Php代码:
$description= $_POST['description'];
$file_path = $file_path . basename( $_FILES['uploaded_file']['name']);
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) {
echo "success";
} else{
echo "fail";
}
图像和音频更新成功。
但参数未收到或我不知道如何在php中接收参数。
我的android和php代码发送和接收参数是否正确?
是否有其他解决方案。
我很努力,但没有工作,也没有想法。

// Send parameter #name
dos.writeBytes("Content-Disposition: form-data; name=\"name\"" + lineEnd);
应该是:
// Send parameter #description
dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd);

检查此link
Android代码:
String description = ""+"Desceiption about the image";
dos.writeBytes("Content-Disposition: form-data; name=\"description\"" + lineEnd);
//dos.writeBytes("Content-Type: text/plain; charset=UTF-8" + lineEnd);
//dos.writeBytes("Content-Length: " + description.length() + lineEnd);
dos.writeBytes(lineEnd);
dos.writeBytes(description); // mobile_no is String variable
dos.writeBytes(lineEnd);
Php代码:
$description =$_POST['description'];
