Javascript 角度+；Express:API在将代码部署到Google云（GCP）时返回HTML而不是JSON,javascript,node.js,angular,google-app-engine,google-cloud-platform,Javascript,Node.js,Angular,Google App Engine,Google Cloud Platform,这是我的项目结构： - /dist (Created after ng build --prod) - index.html - <Other JS/CSS files> - /e2e - /node_modules - app.yaml - server.mjs - package.json 以下是如何在server.mjs中编写我的端点 app.get('/api/description/:ticker', (req, res) => { // a

这是我的项目结构：

- /dist (Created after ng build --prod)
    - index.html
    - <Other JS/CSS files>
- /e2e
- /node_modules
- app.yaml
- server.mjs
- package.json

以下是如何在server.mjs中编写我的端点

app.get('/api/description/:ticker', (req, res) => {
    // api call here
});

...
...
...

app.get('/', (req, res) => {
    res.sendFile(path.join(__dirname, 'dist/index.html'));
});

我的所有端点都以/api开头

这是前端的一个示例呼叫

getDescription(ticker) {
   return this.http.get('api/description/' + ticker);
}

一切都在本地运行。但当我将它部署到GCP时，我似乎无法让它正常工作。上述项目结构与上传至GCP的结构相同

问题：

任何API调用都会返回index.html cause解析错误，但返回值为200 OK

我觉得这个问题与app.yaml文件有关，但在多次尝试和错误后，我无法得到正确的结果

有人知道为什么会这样吗

谢谢

注意：所有东西都在本地工作。在GCP中，页面加载了当前CSS等所有东西。只有API不工作
