java程序在linux服务器中运行，返回的结果为
<head>
<title>Error response</title>
</head>
<body>
<h1>Error response</h1>
<p>Error code 400.
<p>Message: Bad request syntax ('PUT /api/v1.0/task/ file@/data/192.168.1.1/003/weixin/111-746736751-371100-371100-1534545961-02853.zip HTTP/1.1').
<p>Error code explanation: 400 = Bad request syntax or unsupported method.
</body>

以下是我的程序只是向目标服务器发送完整请求如PUT http://192.168.1.1:9733/...
