JAVA如何接收postman中raw参数呢?

 读取流信息
       将流信息写入到一个字节数组中
       然后转换为相应的字符串输出

/**
 * java获取raw
 */
public static String readRaw(InputStream inputStream) {
 
    String result = "";
    try {
        ByteArrayOutputStream outSteam = new ByteArrayOutputStream();
        byte[] buffer = new byte[1024];
 
        int len;
        while ((len = inputStream.read(buffer)) != -1) {
            outSteam.write(buffer, 0, len);
        }
 
        outSteam.close();
        inputStream.close();
 
        result = new String(outSteam.toByteArray(), "UTF-8");
 
    } catch (IOException e) {
        e.printStackTrace();
    }
 
    return result;
}
　　

---测试-----
//result就是raw中的数据
String result = FileUtils.readRaw(request.getInputStream());
