1、在请求微信小程序接口：获取不限制的小程序码 时，报错：errcode：47001，errmsg：data format error rid。如图1
Plaintext
POST https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token={token}
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
scene=1825203750690640&page=pages%2Findex%2Findex
2、调整请求参数的 Content-Type ，得以解决。然后报另外一个错误：errcode：41030，errmsg：invalid page rid。如图2
Plaintext
POST https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token={token}
Content-Type: application/json; charset=UTF-8
{"scene":"1825203750690640","page":"pages\/index\/index","width":null}
3、调整请求参数的 “check_path”:false ，得以解决。然后报另外一个错误：Unrecognized format ”。如图3
Plaintext
POST https://api.weixin.qq.com/wxa/getwxacodeunlimit?access_token={token}
Content-Type: application/json; charset=UTF-8
{"scene":"1825203750690640","page":"pages\/index\/index","width":null,"check_path":false}
4、调整响应格式为 raw-urlencoded，得以解决
PHP
$response = $this->httpClient->createRequest()
->setMethod('POST')
->setUrl('wxa/getwxacodeunlimit?access_token=' . $accessToken)
->setFormat(Client::FORMAT_JSON)
->setData([
'scene' => $scene,
'page' => $page,
'width' => $width,
'check_path' => false,
'env_version' => 'trial'
])
->send();
// 设置响应格式为 raw-urlencoded（二进制数据）
$response->format = Client::FORMAT_RAW_URLENCODED;
