Issue POSTing data to Easyiot cloud

Issue POSTing data to Easyiot cloud was created by mamic2
hi guys,
i have problems while using POST to send data to Easyiot cloud.
In the examples given by Easyiot website, it connects to wifi network, then:
// Set up TCP connection.
String cmd = "AT+CIPSTART=\"TCP\",\"";
cmd += EIOT_CLOUD_ADDRESS;
cmd += "\",40404";
esp8266.println(cmd);
// Sending data
String url = "";
// URL: /RestApi/SetParameter/[instance id]/[parameter id]/[value]
url += "/RestApi/SetParameter/"+ String(EIOT_CLOUD_INSTANCE_PARAM_ID) + "/"+String(temp); // generate EasIoT cloud update parameter URL
esp8266.print(String("POST ") + url + " HTTP/1.1\r\n" +
"Host: " + String(EIOT_CLOUD_ADDRESS) + "\r\n" +
"Connection: close\r\n" +
"Content-Length: 0\r\n" +
"\r\n");
Since this code is not working for me, i would like ot ask if AT+CIPSEND=xxx is needed before POST.
I didnt find it in code provided by Easyiot website.
Thanks for helping me.
Ciao

Hi, I see you are using old REST API. I recommend you to use REST API V1. You can download library here:
iot-playground.com/blog/2-uncategorised/...apiv1-0-library-v1-0
This are two examples with this library:
iot-playground.com/blog/2-uncategorised/...ot-cloud-rest-api-v1

Hi this is what i did to get round not using ESP8266, i am using mega connected to the 8266 and works fine. now to get MQTT working on it.
String url = "";
String values("[{\"Id\": \""+parameterSetTemp+"\", \"Value\": \""+String(SetTemp)+"\" }]");
url = "POST /RestApi/v1.0/Parameter/Values";
client.print(String(url+" HTTP/1.1\r\n") +
"Host: " + String(EIOT_CLOUD_ADDRESS) + "\r\n" +
"EIOT-AuthToken: "+String(token) + "\r\n" +
"Connection: close\r\n" +
"Content-Length: " + values.length() +
"\n\n" +
values +
"\r\n");
String url = "";
String values("[{\"Id\": \""+parameterSetTemp+"\", \"Value\": \""+String(SetTemp)+"\" }]");
url = "POST /RestApi/v1.0/Parameter/Values";
client.print(String(url+" HTTP/1.1\r\n") +
"Host: " + String(EIOT_CLOUD_ADDRESS) + "\r\n" +
"EIOT-AuthToken: "+String(token) + "\r\n" +
"Connection: close\r\n" +
"Content-Length: " + values.length() +
"\n\n" +
