HTTP Client POST Base64 Encoded data

1/ I can encode base64 from base64.c in CC3200SDK (C:\ti\CC3200SDK_1.1.0\cc3200-sdk\netapps\http\server\base64.c) right ?

Yes, there should not be any issue.

2/  In the HTTP client demo example. I can't connect with https . This is my post 

As we requested in last post jump in to HTTPCli_Connect() and share return value (ret) of connect(skt, sa, slen); API

3/  I have tested with python so i have to send 

+ RequestHeaders("{\"Content-Type\": \"audio/l16; rate=16000;\"}")

+RequestParameters("{\"output\": \"json\", \"lang\": \"vi-VN\", \"key\": \"My_token\"}")

+ EncodedData : Base64 encoded data

But in the HTTP client demo example, in HTTPPostMethod.  i can't find the way to send RequestHeaders , RequestParameters , Type for posting binary data.( base64 encoded data).

const HTTPCli_Field fields[4] = {

{"Content-Type, "audio/16; rate=1600},
{"output", "{\"output\": \"json\", \"lang\": \"vi-VN\", \"key\": \"My_token\"}"},
{HTTPStd_FIELD_NAME_ACCEPT, "*/*"}, //If applicable, else remove it 
{HTTPStd_FIELD_NAME_CONTENT_TYPE, "application/json"}, //If applicable, else remove it 
{NULL, NULL}
};

To send any HTTP header use HTTPCli_Field structure and HTTPCli_sendField() API as mentioned above. To send data (base 64 encoded data) use HTTPCli_sendRequestBody() API

Hi,

Thank you for your help.

I want to ask how to get a certificate from a website https

I want to get the general root CA for connecting to Google through HTTPS which is the GeoTrust Global CA.

I found this tutorial. Does it's right ?   If it is which format i should choose for CC3200 using.

Best regards,

Khoa

Hi Khoa,


Yes above steps are right and you need to select der encoded binary format.

Hi Aashish,

If there are two certificates in the web

I just run this code below twice right ? run the top level certificate ( GeoTrust Global CA)  first then run the next level certificate  (Google Internet Authority G2) ? 

or just run one certificate ?

#define SL_SSL_CA_CERT	"/cert/1.crt"
	struct HTTPCli_SecureParams sparams;
	/* Set secure TLS connection  */
	/* Security parameters */
	sparams.method.secureMethod = SL_SO_SEC_METHOD_TLSV1_2;
	sparams.mask.secureMask = SL_SEC_MASK_TLS_RSA_WITH_AES_256_CBC_SHA; //SL_SEC_MASK_TLS_RSA_WITH_AES_256_CBC_SHA;
	strncpy(sparams.cafile, SL_SSL_CA_CERT, sizeof(SL_SSL_CA_CERT));
	sparams.privkey[0] = 0;
	sparams.cert[0] = 0;
	sparams.dhkey[0] = 0;
	HTTPCli_setSecureParams(&sparams);

Best regards,

Hi Khoa,


Use root CA certificate.

Hi Aashish,

You mean the top level certificate ( GeoTrust Global CA) ?

Hi Khoa,


Yes. Top level certificate.

Hi Aashish,

Would you mind if i ask you some question

1/ when the request POST send successfully and Google is 100% confident in it's translation,

It will return the following object:

{
  "result":[
    {
      "alternative":[
        {
          "transcript":"this is a test",
          "confidence":0.97321892
        },
        {
          "transcript":"this is a test for"
        }
      ],
      "final":true
    }
  ],
  "result_index":0
}

So I have to use lRetVal = readResponse(httpClient); (at the end of function HTTPPostMethod)  to receive the return data

if i use readResponse, the header will be 

	const char *ids[5] = {
			HTTPCli_FIELD_NAME_CONTENT_LENGTH,
			HTTPCli_FIELD_NAME_CONNECTION,
			HTTPCli_FIELD_NAME_CONTENT_TYPE,
			"result",
			NULL
	};

with "result " in ids[5], cc3200 can receive the result from google, right ?

Would you mind helping me

2/ if the certificate is Google 2.cer, in UniFlash i have to name the file to /cert/1.cer . 

But in the SSL_demo wiki, in section Usage. It said i have to name the file to /cert/129.der or  /cert/129.crt

 

Are there any difference ?

3 Do you have any solutions to send http post more than 16kb

Best regards,

Khoa

Tuan, were you able to send to GeoTrust Global CA? If so what were your securemethod, and securemask settings? I am unable to connect to my server. Still getting -102
