sapui5 - 从错误路径加载library.js

Question

我已将项目的 OpenUI5 从 1.42.7 更新到 1.60.12 (LTS)

如果我尝试使用新版本运行应用程序，则会出现此错误:

Uncaught Error: failed to load 'sap/ui/core/library.js' from resources/sap/ui/core/library.js: 404 - Not Found**

我的项目的树结构将 OpenUI5 文件放入 resources/openui路径:

在index.html中，我设置了src在此模式下:

<script id="sap-ui-bootstrap"
  src="resources/openui/sap-ui-core.js"
  data-sap-ui-theme="sap_belize"
  data-sap-ui-xx-bindingSyntax="complex"
  data-sap-ui-libs="sap.m"
  data-sap-ui-preload=""
  data-sap-ui-resourceroots='{
    "ui5bp": "./",
    "model": "./model"
  }'
></script>

看来是sap-ui-core.js的第一次调用正确完成(来自 Webcontent/resources<strong>/openui</strong> )，但随后调用 library.js从 Webcontent/resources/ 调用，不是来自 Webcontent/resources/openui .

在1.42版本中，一切正常。
注意:如果我尝试从 CDN 检索 OpenUI5 资源，一切正常...

Answer 1

选项 1(推荐)

将 UI5 资源移动到正下方的 resources 文件夹中。

˅ 📂resources  ˃ 📁openui  ˅ 📂sap    ˃ 📁base    ˃ 📁f    ˃ 📁m    ...  ...  sap-ui-core.js

According to the topic Bootstrapping: Loading and Initializing - Initialization Process, UI5 will try to fetch library resources from the following path by default:

Library bootstrap file /<context-path><strong>/resources/<library-name></strong>/library(-preload).js

Having a deviating path (/resources/<strong>openui/</strong><library-name>/ in between) makes fetching the library files incompatible with default settings.

Option 2 (without changing the folder structure)

Define a new default base URL in index.html as early as possible. E.g. via the global configuration object:

<script>
  window["sap-ui-config"] = {
    resourceRoots: {
      "": "./resources/openui/", // <-- new base URL
      "ui5bp": "./",
      // ...
    },
    libs: "sap.ui.core, sap.m",
    async: true,
    theme: "sap_belize",
    compatVersion: "edge",
    // ...
  };
</script>
<script id="sap-ui-bootstrap" src="resources/openui/sap-ui-core.js"></script>

这个也有效，因为解决""将始终作为后备工作

Note that the empty prefix ("") will always match and thus serves as a fallback for any search. ^source
