问题描述
我正在尝试根据此链接“ https://developer.paytm.com/docs/v1/android-sdk/”实现Paytm网关，但是在应用程序Webview中打开，我陷入了Paytms处理页面。以下是我正在尝试的演示代码。请帮忙，因为Paytm没有帮助。我没有丢失任何参数，因为如果删除/更改任何参数，它将显示特定参数的错误。 首先，我要在服务器上创建订单ID，然后是校验和，然后调用Paytm服务。 使用相同校验和的同一件事在PC浏览器上有效，但在android上无效。

解决方法
发生这种情况是因为您的服务器可能您忘记返回响应 Paytm SDK 没有问题它在交易发生期间触发回调...
使用回调 URL Post Request "https://securegw.paytm.in/theia/paytmCallback?ORDER_ID=" 从服务器请求这个 url 创建自己的回调 URL 在您的服务器内
尝试从您的服务器端检查它会修复
,您应该集成其开发人员页面上提供的提供了多合一SDK的新SDK。请参考集成。
,Add Paytm All in One SDK dependency in Project-level Gradle file: -
allprojects {
repositories {
google()
jcenter()
maven {
url "https://artifactory.paytm.in/libs-release-local"
}
}
}
Now add another dependency in the module level Gradle file.
