cordova ios 6.1.0 wkwebview某些xhr POST失败

Question

随着每个人都在使用离子堆栈进行开发，由于苹果的要求，我们也进入了新的wkwebview。

我们已经提供了一个没有任何警告的ios构建(关于uiwebview旧代码(，但在执行某些POST调用时仍然遇到问题。

设置

我们已经设置了如下的cors服务器端(Apache(：

<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>com.hrd.auth.tomcat7.cors.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.origins</param-name>
<param-value>app://myapp, http://localhost:9090</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
</init-param>
<init-param>
<param-name>cors.allowed.headers</param-name>
<param-value>Content-Type,X-Requested-With,Accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers,User-Agent,DEVICE_ID</param-value>

问题

应用程序执行成功的POST登录调用，并提供以下xhr详细信息

"{"method":"POST",
"post":"{
\"username\":\"username\",
\"password\":\"password\"
}",
"url":"http://192.168.1.129:8080/go/rest/security/appLogin/MY_APP_LOGIN",
"headers":{"Content-Type":"application/json",
"DEVICE_ID":"a91d602c140079f2e848f39e33a6ca88",
"Accept":"application/json,text/plain,*/*"},
"withCredentials":true}"

但是，在这个调用中(在经过身份验证后执行(，正在失败：

"{"method":"POST",
"post":"{
\"test\":\"test\"
}",
"url":"http://192.168.1.129:8080/go/rest/security/userInfo",
"headers":{
"Accept":"application/json,text/plain,*/*",
"Content-Type":"application/json;charset=utf-8"
},
"withCredentials":true}"

环境配置

• 包含以下堆栈的离子束**ionic.js 1.3.2**angularJS 1.5.3
• cordova 9.0.0
• cordova ios 6.1.0

有人知道为什么这种呼叫失败吗？

常见问题

1. 与第一个(登录调用(不同，第二个没有到达服务器CorsFilter.java类，所以调用"不退出APP">
2. 与移动环境不同，我们的小部件环境已经修复了POST调用，只是将调用负载模拟数据放入其中，以抱怨w3c浏览器规范

非常感谢Simone

Answer 1

我们发现了调用无法到达服务器CorsFilters.java类的问题(因此不可能获得一些调试实例(。

阅读我们的服务器日志，我们发现了这一行

192.168.x.x - - [02/Sep/2020:17:40:09 +0200] "OPTIONS /go/rest/security/userInfo HTTP/1.1" 401 7361 4286

这是关于飞行前POST请求的一个众所周知的问题，所以我们只需在web.xml conf.文件中添加以下属性

<web-resource-collection>
<web-resource-name>REST</web-resource-name>
<description>REST services</description>
<url-pattern>/rest/*</url-pattern>
<http-method-omission>OPTIONS</http-method-omission> <<--- add this row
</web-resource-collection>

这样，所有OPTIONS请求都将被接受，而不是被拒绝！

希望这能帮助头痛数周的人；(
