送分题！首先的首先，涉及业务逻辑的输入是需要通过参数传递的，主要有三种方法：path, query, POST/PUT bodypath: GET /api/user/123 其中的123通过path传递query: GET /api/search_user?userId=123body: POST /api/user-signup {username: ‘john’}不建议通过header传参的原因:1. proxy 和 reverse proxy会drop header2. 不利于传输object3. HTTP access control (CORS) API 一般会设置Access-Control-Allow-Headers，分分钟教你做人。4. 不利于dev和debug5. Header长度限制然后，如果你需要传header，比如Authorization，如下。jQuery.ajax()headers (default: {})Type: PlainObjectAn object of additional header key/value pairs to send along with requests using the XMLHttpRequest transport. The header X-Requested-With: XMLHttpRequest is always added, but its default XMLHttpRequest value can be changed here. Values in the headers setting can also be overwritten from within the beforeSend function. (version added: 1.5)
