cordova ios 6.1.0 wkwebview 一些 xhr POST 失败

Question

随着每个人的发展。使用离子堆栈，由于 Apple 的要求，我们也正在迁移到新的 wkwebview。

我们已经在没有任何警告（关于 uiwebview 旧代码）的情况下为 ios 提供了构建，但是我们在执行一些 POST 调用时仍然遇到问题。

设置

我们已经像下面这样设置了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>
    </init-param>
    <init-param>
        <param-name>cors.exposed.headers</param-name>
        <param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
    </init-param>
    <init-param>
        <param-name>cors.support.credentials</param-name>
        <param-value>true</param-value>
    </init-param>
    <!-- <init-param>
        <param-name>cors.preflight.maxage</param-name>
        <param-value>10</param-value>
    </init-param> -->
</filter>
<filter-mapping>
    <filter-name>CorsFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

下面改为当前APP配置：

问题

APP成功POST调用登录，xhr详情如下

"{\"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，在此调用中（在经过身份验证后执行）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

ionic-bundle 包含以下堆栈 ** ionic.js 1.3.2 ** angularJS 1.5.3
科尔多瓦 9.0.0
科尔多瓦-ios 6.1.0

有人知道为什么这种调用会失败吗？

常见问题解答

与第一个（登录调用）不同，第二个未到达服务器 CorsFilter.java class，因此调用“不退出 APP”
我们的 widget 环境与移动环境不同，已针对 POST 调用进行了修复，只是将调用有效负载模拟数据放入内部，以抱怨 w3c 浏览器规范。

非常感谢西蒙

Answer 1

我们发现有关调用未到达服务器 CorsFilters.java class 的问题（因此无法获得一些调试实例）。

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

这是一个关于预检 POST 请求的众所周知的问题 - 我们只需在我们的 web.xml conf 中添加。提交以下属性

<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，所有的 OPTIONS 请求都会被接受而不是被拒绝！

希望这对头痛一周的人有所帮助；）
