OutputStreamを閉じてしまっているのが原因ではないかとご指摘いただいたので、送信部分下記のように変更して試してみました。
|
|
101
|
+
``` Java
|
|
102
|
+
try (InputStream is = Files.newInputStream(uploadFile);
|
|
103
|
+
OutputStream os = connection.getOutputStream();) {
|
|
104
|
+
int len;
|
|
105
|
+
byte[] buf = new byte[8192];
|
|
106
|
+
try {
|
|
107
|
+
while ((len = is.read(buf, 0, buf.length)) > 0) {
|
|
108
|
+
os.write(buf, 0, len);
|
|
109
|
+
}
|
|
110
|
+
} catch (Exception e) {
|
|
111
|
+
e.printStackTrace();
|
|
112
|
+
}
|
|
113
|
+
System.out.println(connection.getResponseCode());
|
|
114
|
+
} catch (Exception e) {
|
|
115
|
+
e.printStackTrace();
|
|
116
|
+
}
|
|
117
|
+
```
|
|

レスポンスを取得しようとした時に、内部でcloseが呼ばれているようでした。
