百度云短信对接,参数配置实例

感觉百度云短信用的人不多,网上也都没什么教程,虽然百度那边有人员对接,但是不是直接对接技术人员,这次我花了一天时间也没搞定。后来感觉应该是参数问题,和他们确定之后,确实是。我直接把代码贴上来,给大家参考。

下面是百度那边给的案例,我把走通的配置标注在代码里了,在框架中只要稍微改下就行,就不贴代码啦。

核心代码sendMessage.php:

<?php

require "auth.php";

// 第一步:生成认证字符串

$ak = "xxxxxx";  // AccessKeyId
$sk = "xxxxxx";  // SecretAccessKey

$method = "POST";

$host = "smsv3.bj.baidubce.com";//每个账号可能不同
$uri = "/api/v3/sendSms";
$url = "http://".$host.$uri;
$params = array();

date_default_timezone_set('UTC');
$timestamp = new \DateTime();
$expirationInSeconds = 3600;

$authorization = generateAuthorization($ak, $sk, $method, $host, $uri, $params, $timestamp, $expirationInSeconds);
print("authorization: {$authorization}\n");

// 第二步:构造HTTP请求的header、body等信息

$timeStr = $timestamp->format("Y-m-d\TH:i:s\Z");
$head =  array(
    "Content-Type:application/json",
    "Authorization:{$authorization}",
    "host:{$host}",
    "x-bce-date:{$timeStr}"
    );
//重要*****
$body = array(
    "mobile" => "13612341234",
    "sign" => "xxxx",//签名内容,也可能是签名id
    "type" => "normal",
    "custom" => "",//随便写123都可以
    "template" => "sms-tmpl-EFKqOl65111"//模板,我之前用smstpl:sms-tmpl-EFKqOl65111,这个不行
     "contentVar" => array("content" => "12345")
    );
$bodyStr = json_encode($body);

// 第三步:发送HTTP请求,并输出响应信息。

$curlp = curl_init();
curl_setopt($curlp, CURLOPT_POST, 1);
curl_setopt($curlp, CURLOPT_URL, $url);
curl_setopt($curlp, CURLOPT_HTTPHEADER, $head);
curl_setopt($curlp, CURLOPT_POSTFIELDS, $bodyStr);

curl_setopt($curlp, CURLINFO_HEADER_OUT, 1);
curl_setopt($curlp, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($curlp);
$request = curl_getinfo($curlp, CURLINFO_HEADER_OUT);
$status = curl_getinfo($curlp, CURLINFO_HTTP_CODE);
curl_close($curlp);

print("request: {$request}\n");
print("request body: {$bodyStr}\n");
print("status: {$status}\n");
print("response: {$response}\n");

这是一个工具类auth.php
