[参考译文] LAUNCHXL-CC3235SF：无法使用 SDK 中提供的 HttpGet 示例、通过 http Post 方法使用服务器

您的 REQ_body 实际上已发送，您可以在 PHP 服务器端使用 诸如 file_get_contents ('php：//input')之类的内容进行验证；

问题是、您不会在应用程序头中发送内容类型、因此它会被服务器接收但丢弃。 添加如下内容：

HttpClient_setHeader (httpClientHandle、HttpClient_HFIELD_REQ_content_type、"application/json"、strlen ("application/json")、HttpClient_HFIELD_NOT_PERSISTENT)；

您好 Sarju、

您获得的错误代码是-2006、这意味着参数无效。 看一下您的代码、您似乎已经正确地放置了所有内容。 我建议您仔细检查 HOSTNAME 是否为有效站点、因为我认为问题所在。

此致、

Rogelio

感谢您的回复！

             现在情况已经发生了一些变化。 请参阅随附的屏幕截图

这是我的代码

void* httpTask(void *pvParameters)
{
    bool moreDataFlag = false;
    char data[HTTP_MIN_RECV];
    int16_t ret = 0;
    int16_t len = 0;

    Display_printf(display, 0, 0, "Sending a HTTP POST 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_setHeader(httpClientHandle,
                                HTTPClient_HFIELD_REQ_AUTHORIZATION,
                                USER_AGENT, strlen(USER_AGENT) + 1,
                                HTTPClient_HFIELD_PERSISTENT);

    if (ret < 0)
    {
        printError("httpTask: setting request header failed", ret);
    }

    /*suggested header settings*/
    ret = HTTPClient_setHeader(httpClientHandle, HTTPClient_HFIELD_REQ_CONTENT_TYPE, "application/json", strlen("application/json"), HTTPClient_HFIELD_PERSISTENT);

    if (ret < 0)
    {
        printError("httpTask: setting request header failed", ret);
    }

    // setting charset=utf-8
    ret = HTTPClient_setHeader(httpClientHandle,HTTPClient_HFIELD_REQ_ACCEPT_CHARSET,"charset=utf-8", strlen("charset=utf-8"), HTTPClient_HFIELD_PERSISTENT);

    if (ret < 0)
    {
      printError("httpTask: setting request header failed", ret);
    }

    ret = HTTPClient_setHeaderByName(httpClientHandle,HTTPClient_HFIELD_REQ_CONTENT_TYPE,"x-api-key","d5da633b5e341xxxxxxxxxxxb6d26a66e007edca0924c482c194b5962ebc276242c", strlen("d5da633b5e341xxxxxxxxxxxb6d26a66e007edca0924c482c194b5962ebc276242c"), HTTPClient_HFIELD_PERSISTENT);

    if (ret < 0)
    {
      printError("httpTask: setting request header failed", ret);
    }

    ret = HTTPClient_setHeaderByName(httpClientHandle,HTTPClient_HFIELD_REQ_CONTENT_TYPE,"x-app-name","bss_exxxn_client", strlen("bss_exxxn_client"), HTTPClient_HFIELD_PERSISTENT);

    if (ret < 0)
    {
      printError("httpTask: setting request header failed", ret);
    }

    ret = HTTPClient_setHeaderByName(httpClientHandle,HTTPClient_HFIELD_REQ_CONTENT_TYPE,"x-svc","svc3xxx3469", strlen("svc3xxx3469"), HTTPClient_HFIELD_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_POST,
                                    REQUEST_URI,
                                    REQ_BODY,
                                    strlen(REQ_BODY), 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);
}

正如您在代码中看到的、我在标头中添加了一些键和值。 请告诉我服务器未回复的错误位置、并且我不断收到错误

错误！ 代码= 400、说明= httpTask：无法获取状态

帮助我摆脱这个问题。

再次感谢！
