In this case, you will have to ensure that each operation ID is **unique** in some other way.

For example, you could make sure that each *path operation* has a tag, and then generate the operation ID based on the **tag** and the *path operation* **name** (the function name).

### Custom Generate Unique ID Function { #custom-generate-unique-id-function }

containing debug information. Cgo parses the DWARF debug information
for __cgo__N to learn the type of each identifier. (The types also
distinguish functions from global variables.) Cgo reads the constant
values from the __cgodebug_* from the object file's data segment.

At this point cgo knows the meaning of each C.xxx well enough to start
the translation process.

Translating Go

```
https://example.com/items/foo
```

...đường dẫn sẽ là:

```
/items/foo
```

/// info

Một đường dẫn cũng là một cách gọi chung cho một "endpoint" hoặc một "route".

Trong khi xây dựng một API, "đường dẫn" là các chính để phân tách "mối quan hệ" và "tài nguyên".

#### Toán tử (Operation)

"Toán tử" ở đây được nhắc tới là một trong các "phương thức" HTTP.

Một trong những:

 * ...
 * ThreadN: acquire(LockN) --X acquire(LockA)
 * </pre>
 *
 * <p>The implementation detects cycles by constructing a directed graph in which each lock
 * represents a node and each edge represents an acquisition ordering between two locks.
 *
 * <ul>
 *   <li>Each lock adds (and removes) itself to/from a ThreadLocal Set of acquired locks when the
 *       Thread acquires its first hold (and releases its last remaining hold).

client can use now `mybucket.domain.com` to directly resolve itself to the right cluster. `MINIO_PUBLIC_IPS`
points to the public IP address where each cluster might be accessible, this is unique for each cluster.

NOTE: `mybucket` only exists on one cluster either `cluster1` or `cluster2` this is random and
is decided by how `domain.com` gets resolved, if there is a round-robin DNS on `domain.com` then

Aber das ist immer noch nicht so nützlich.

You can add middleware to **FastAPI** applications.

A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).
