I am making a HTTP POST query to a server and I am creating the post body manually. I think I am making some mistake with the content-length header because on the server side when I get the http response at the beginning I see the headers with http response 200 and then when in my php script I print the post parameters and file names I get the correct values but together with some junk bytes. Here is the body of my http post:
StringBuffer str = new StringBuffer();
str.append("POST /tst/query.php HTTP/1.1rn"
+ "Host: myhost.comrn"
+ "User-Agent: sampleAgentrn"
+ "Content-type: multipart/form-data, boundary=AaB03xrn"
+ "Content-Length: 172rnrn"
+ "--AaB03xrn"
+ "content-disposition: form-data; name="asd"rnrn123rn--AaB03xrn"
+ "content-disposition: form-data; name="pics"; filename="file1.txt"rn"
+ "Content-Type: text/plainrnrn555rn"
+ "--AaB03x--"
);
Here is the output from the server(ignore [0.0] – it comes from the console where I print the result)
[0.0] HTTP/1.1 200 OK [0.0] Date: Sat, 10 Dec 2011 11:53:11 GMT [0.0] Server: Apache [0.0] Transfer-Encoding: chunked [0.0] Content-Type: text/html [0.0] [0.0] 6 [0.0] Array [0.0] [0.0] 2 [0.0] ( [0.0] [0.0] 1 [0.0] [0.0] 1 [0.0] [0.0] 1 [0.0] [0.0] 1 [0.0] [0.0] 1 [0.0] [ [0.0] 3 [0.0] asd [0.0] 5 [0.0] ] => 3 123 1 2 ) 0
And the php script on the server which is as simple as you can think of:
<?php
print_r($_POST) ;
?>

String boundary = "AaB03x";
String body = "--" + boundary + "rn"
+ "Content-Disposition: form-data; name="asd"rn"
+ "rn"
+ "123rn"
+ "--" + boundary + "rn"
+ "Content-Disposition: form-data; name="pics"; filename="file1.txt"rn"
+ "Content-Type: text/plainrn"
+ "rn"
+ "555rn"
+ "--" + boundary + "--";
StringBuffer str = new StringBuffer();
str.append("POST /tst/query.php HTTP/1.1rn"
+ "Host: myhost.comrn"
+ "User-Agent: sampleAgentrn"
+ "Content-type: multipart/form-data, boundary="" + boundary + ""rn"
+ "Content-Length: " + body.length() + "rn"
+ "rn"
+ body
);
…I would say is the way it should be done
