您好。
我使用httpget例程进行改造。我想从我的云服务器上获取数据。请问按照下面的例程是否可以达到效果？
还有HTTPClient_connect函数得不到任何返回值。是哪里设置的不对吗？
※我对网址进行了简化处理，请见谅。云服务器地址在我自己电脑可以访问的。
#define HOSTNAME"https://private.test-api.ap-3.amazonaws.com/test"
#define REQUEST_URI"/0/dev/macaddr"
void* httpTask(void* pvParameters)
{bool moreDataFlag = false;char data[HTTP_MIN_RECV];int16_t ret = 0;int16_t len = 0;memset(data,0,512);ret = -1;moreDataFlag = 1;Display_printf(display, 0, 0, "Sending a HTTP GET request to '%s'\n",HOSTNAME);HTTPClient_Handle httpClientHandle;int16_t statusCode;httpClientHandle = HTTPClient_create(&statusCode,0);if(statusCode < 0){printError("httpTask: creation of http client handle failed",statusCode);}ret = HTTPClient_setHeaderByName(httpClientHandle,HTTPClient_HFIELD_REQ_USER_AGENT,"x-api-key","test",strlen("test")+1,HTTPClient_HFIELD_NOT_PERSISTENT);if(ret < 0){printError("httpTask: setting request header failed", ret);}ret = HTTPClient_connect(httpClientHandle,HOSTNAME,0,0);if(ret < 0){printError("httpTask: connect failed", ret);}ret =HTTPClient_sendRequest(httpClientHandle,HTTP_METHOD_GET,REQUEST_URI,NULL,0,0);if(ret < 0){printError("httpTask: send failed", ret);}if(ret != HTTP_SC_OK){printError("httpTask: cannot get status", ret);}Display_printf(display, 0, 0, "HTTP Response Status Code: %d\n", ret);len = 0;do{ret = HTTPClient_readResponseBody(httpClientHandle, data, sizeof(data),&moreDataFlag);if(ret < 0){printError("httpTask: response body processing failed", ret);}Display_printf(display, 0, 0, "%.*s \r\n",ret,data);len += ret;}while(moreDataFlag);Display_printf(display, 0, 0, "Received %d bytes of payload\n", len);ret = HTTPClient_disconnect(httpClientHandle);if(ret < 0){printError("httpTask: disconnect failed", ret);}HTTPClient_destroy(httpClientHandle);return(0);
}

OTA示例中展示了如何使用http从服务器中获取数据，你可以参考Cloud OTA例程：
https://www.ti2k.com/wp-content/uploads/ti2k/DeyiSupport_WIFI_node
SDK5.20及以前的版本都包含此例程，可以从中查看http获取数据的使用方法

Zhujun He：
非常感谢您的回答。问题已经解决。
我服务器网址是https所以需要认证证书。安装后，可正常上传数据。
