For example if we wanted to attack our API with multiple endpoints, we would create a targets file targets.txt: Vegeta also allows us to define headers using [header name]: [header value]and body using @[file]: With the newuser.json file being the body of the request: Using the targets file, we can then load test all endpoints on our application with predefined requests. -rate specifies the rate of the attack in requests per seconds here we are sending 5 requests per seconds. Here we'll use pdsh for orchestration. How do I find the encoding of the current buffer in vim? You could be CPU bound (unlikely), memory bound (more likely) or Python supports two locale-dependent encodings in Windows. File paths starting with a dash are unfriendly, and so are very long paths (e.g. How can I format the output of the first script, so that the second can be made to identify each type correctly? Web APIs are a ubiquitous part of modern web or app development. If you know (and document) that the unknown strings are nice enough to not contain control characters such as newlines (so they each are a single line) you could decide for some format like, then write and use some simple awk script (or perhaps use sed) for your second script.
