我正在向服务器发出HTTP POST查询,我正在手动创建帖子正文。 我认为我在内容长度标题上犯了一些错误,因为在服务器端,当我在开始时得到http响应时,我看到带有http响应200的标题然后在我的php脚本中我打印了post参数和文件名我得到正确的值,但加上一些垃圾字节。 这是我的http帖子的正文:
StringBuffer str = new StringBuffer();
str.append("POST /tst/query.php HTTP/1.1\r\n"
+ "Host: myhost.com\r\n"
+ "User-Agent: sampleAgent\r\n"
+ "Content-type: multipart/form-data, boundary=AaB03x\r\n"
+ "Content-Length: 172\r\n\r\n"
+ "--AaB03x\r\n"
+ "content-disposition: form-data; name=\"asd\"\r\n\r\n123\r\n--AaB03x\r\n"
+ "content-disposition: form-data; name=\"pics\"; filename=\"file1.txt\"\r\n"
+ "Content-Type: text/plain\r\n\r\n555\r\n"
+ "--AaB03x--"
);
这是服务器的输出(忽略[0.0] - 它来自我打印结果的控制台)

服务器上的php脚本就像你能想到的一样简单:
<?php
print_r($_POST) ;
?>
答案 0 :(得分:2)
来自HTTP RFC(RFC2626, 14.3)
Content-Length entity-header字段指示实体主体的大小,以十进制数量的OCTET发送给接收者,或者在HEAD方法的情况下,指示实体主体的大小。如果请求是GET,则已发送。
换句话说,你应该计算字节数(octets
),因此\r\n
应该被认为是2个八位字节/字节。

String boundary = "AaB03x";
String body = "--" + boundary + "\r\n"
+ "Content-Disposition: form-data; name=\"asd\"\r\n"
+ "\r\n"
+ "123\r\n"
+ "--" + boundary + "\r\n"
+ "Content-Disposition: form-data; name=\"pics\"; filename=\"file1.txt\"\r\n"
+ "Content-Type: text/plain\r\n"
+ "\r\n"
+ "555\r\n"
+ "--" + boundary + "--";
StringBuffer str = new StringBuffer();
str.append("POST /tst/query.php HTTP/1.1\r\n"
+ "Host: myhost.com\r\n"
+ "User-Agent: sampleAgent\r\n"
+ "Content-type: multipart/form-data, boundary=\"" + boundary + "\"\r\n"
+ "Content-Length: " + body.length() + "\r\n"
+ "\r\n"
+ body
);
......我想说的是应该这样做的方式
