php 如何接受并转换http字节流

我做一个php服务端, java客户端以http post方式,把文件流转换为字节流,再setEntity给我, java代码片段如下:
        HttpPost post = new HttpPost(postUrl);
        ByteArrayEntity entity = new ByteArrayEntity(outputStream.toByteArray());
        post.setEntity(entity);
        if (httpClient == null) {
          httpClient = new DefaultHttpClient();
        }
        HttpResponse response = httpClient.execute(post);

我这边需要接受http字节流,并且全部转字符串,然后做解析。
1.请问我这边应该如何去获取流?用什么接口?php://input
2.获取后字节流如何转字符串? chr?unpack?还是如何?
我感觉不是普通应用层的http方式, 是比较原始的接受http数据的方式,请大牛帮忙指点方向.

(目前我用file(php://input)获取字节流,然后chr() 转ASCII字符再写入文件查看,貌似都是乱码)
注:字节流里面只有ascii字符,没有中文字符.


回复讨论(解决方案)

补充下:

原始文件流里面的内容如下:
launch    {"primary":"-1415673003223"}    1415673003223
controller    {"model":"Test Controller","primary":"count"}    1415673003991
click    {"click_name":"Test Button Name","primary":"count"}    1415673004598
view    {"view_name":"Test Page Name","primary":"1415673005202"}    1415673005203
view    {"view_name":"Test Page Name","primary":"-1415673005795"}    1415673005795
game    {"package_name":"Test Game","primary":"1415673007231"}    1415673007231
game    {"package_name":"Test Game","primary":"-1415673008047"}    1415673008051

如果只是存入文件 你可以

$path ="/tmp/newfile"$content = isset($GLOBALS["HTTP_RAW_POST_DATA"]) ? $GLOBALS["HTTP_RAW_POST_DATA"] : '';file_put_contents($path, $fileContent);
Copy after login
Copy after login


如果要进行处理 你需要
$content = isset($GLOBALS["HTTP_RAW_POST_DATA"]) ? $GLOBALS["HTTP_RAW_POST_DATA"] : '';//然后对$content进行字符串处理得到你需要的结构
Copy after login
Copy after login

$path ="/tmp/newfile"$content = isset($GLOBALS["HTTP_RAW_POST_DATA"]) ? $GLOBALS["HTTP_RAW_POST_DATA"] : '';file_put_contents($path, $fileContent);

我试了下您的方式, 取出来的content是乱码,这也是一直我卡住的地方。如您所见,java端在最初写入文件,到读取文件流,到转换字节流,到setEntity都没有做字符编码的特殊处理。所以接下来如何处理乱码的问题呢?


$s = file_get_contents('php://input');
file_put_contents('test.txt', base54_encode($s));

贴出 test.txt 的内容


$s = file_get_contents('php://input');
file_put_contents('test.txt', base54_encode($s));

你说的是base64_encode吧,请指教!


$s = file_get_contents('php://input');
file_put_contents('test.txt', base54_encode($s));

刚刚用mb_detect_encoding($s, "auto") 检测了下 返回的是UTF-8, 但是存到文件里用vim看是乱码。难道是vim的问题?


$s = file_get_contents('php://input');
file_put_contents('test.txt', base54_encode($s));

我把文件拷贝到本地用配置好UTF-8的vim 查看,还是乱码...

接收到的的确是“乱码”,因为他做了 gzip 压缩

这个回答完全正确!确实是做了gzip压缩,交学费了!而且我之前也是知道他把文件流做了gzip压缩, 但是对这个不清楚所以也没有在提问中说道,自己也没有望着方面想。
另外请教一下, 你是如何得知做了gzip压缩的?小弟刚开始做php,希望不吝赐教!

感谢回答,另外也感谢orangeholic 这位朋友的帮助!

base64 解码后的是二进制串,而你在#1补充了原始文件的样式(显然不是二进制的)
所以尝试了可能的压缩算法,不想一下就对上了

补充一下,得到的串的同两个字符是 "\x1f\x8b"
这是 gzip 的文件头标识
