当我尝试部署到 App Engine 时错误发布到 URL 400 Bad Request

Question

几个月前，我的应用程序可以完美地部署到 appengine，但我今天尝试部署它，但我在日志中收到以下错误：

Please see the logs [/var/folders/dg/1d63fk7n5r9c05hnbn7z2nx80000gp/T/appcfg6594780979158835679.log] for further information.

我认为问题出在url中指定的app_id； https://appengine.google.com/api/appversion/getresourcelimits?app_id=%24%7Bapp.id%7D&version=1&

那个url里面的app_id是%24%7Bapp.id%7D其实是ornate-woodland-130423

这是我的appengine_web.xml：

<?xml version="1.0" encoding="utf-8"?>
<appengine-web-app xmlns="http://appengine.google.com/ns/1.0">
    <application>${app.id}</application>
    <version>${app.version}</version>
    <threadsafe>true</threadsafe>

    <system-properties>
        <property name="java.util.logging.config.file" value="WEB-INF/logging.properties"/>
    </system-properties>
</appengine-web-app>

摘自我的pom.xml：

<properties>
    <app.id>ornate-woodland-130423</app.id>
    <app.version>1</app.version>
    <appengine.version>1.9.37</appengine.version>
    <gcloud.plugin.version>2.0.9.89.v20151202</gcloud.plugin.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.showDeprecation>true</maven.compiler.showDeprecation>
</properties>

我有办法解决这个问题吗？

Answer 1

这不起作用的原因是因为 app.id 需要在 appengine_web.xml 中明确指定。因此，为什么在 URL 中它说 app.id 是 %24%7Bapp.id%7D。正如上面有人指出的那样，这实际上是 ${app.id}。

所以不要像这样隐式设置它；

<application>${app.id}</application>

我把它改成了这个，它起作用了

<application>ornate-woodland-130423</application>
