One problem using PROC HTTP

[fanfanpao]

Hello, I meet a problem when using PROC HTTP to get the data from web. I use Linux and SAS 9.4 M5.

Below curl command works.

curl -X POST -H 'xxxxx: xxxx' -i 'http://url/api/' --data '{"attr1":[1284,1296,1300,1426,1428],"attr2":[664,622,657],"attr3":[],"attr4":[],"attr5":["2014-07-02","2015-05-09"]}'

But I use the PROC HTTP failed.

proc http url="http://url/api/" method="POST" out=resp in=input;
headers "xxxxx"="xxxx";
debug level=3;
run;

The in=input have the "{"attr1":[1284,1296,1300,1426,1428],"attr2":[664,622,657],"attr3":[],"attr4":[],"attr5":["2014-07-02","2015-05-09"]}".

I tried to remove the "[" and "]", but still didn't work. Could someone help me?

want to add onething, the response from server is incorrect parameter. so probably the problem should be the in=input values was not recognized well by the server.
