Simple and lightweight golang package for http requests. based on powerful net/http
Grequest is inspired by the Request library for Python and Guzzle in PHP, the goal is to make a simple and convenient library for making http requests in go
The library has a flexible API with methods that return a pointer to the library structure, which allows you to declaratively describe a request using a chain of methods.
Installation
go get github.com/lib4u/grequest
Usage
Simple get request anf get string response
req := app.Get("https://jsonplaceholder.typicode.com/todos/1").Do()
response := req.Body().GetStrings()
fmt.Println(response)
Get a response and writing it to a json structure
type AutoGenerated struct {
UserID int `json:"userId"`
ID int `json:"id"`
Title string `json:"title"`
Completed bool `json:"completed"`
}
...
var myJsonResponse AutoGenerated
req := app.Get("https://jsonplaceholder.typicode.com/todos/1").Do()
err := req.Body().GetWithJsonStruct(&myJsonResponse)
if err != nil {
fmt.Println("do ..")
}
fmt.Println(myJsonResponse.Title)
Simple post request with json payload body and get status of response
data := LoginRequest{
Username: "example",
Password: "12345",
}
req := app.Post("https://example.site/login").Body().SetJson(data).Do()
fmt.Println(req.Status().GetCode())
Simple save file from response
// file will saved as ../files/image.png
app.Get("https://example.com/image.png").Do().Body().SaveFile()
//OR
app.Get("https://example.com/image.png").Do().Body().Path("/user/files").SaveFile()
//OR
app.Get("https://example.com/image.png").Do().Body().ToFile("path/savedimage.png")
Sending form with files and text fields and set header
req := app.Post("https://example.site/form/")
req.Header().Set("Client", "number_1")
form := req.FormData().WithMultipart()
form.AddField("first_name", "John")
form.AddField("last_name", "Doe")
form.AddFile("photo", "my_photo.png")
form.AddFile("documents", "example.txt")
form.AddFile("documents", "example2.txt")
form.Push()
req.Do()
.....
Request with authentication
//With basic auth
req := app.Post("https://example.site/secret)
req.Header().Set("Client", "number_1")
req.Auth().SetBasic("user", "password")
req.Do()
...
//Sets bearer token
req := app.Post("https://example.site/secret)
req.Header().Set("Client", "number_1")
req.Auth().SetBearer("myToken")
req.Do()
Work with cookie
//Save cookie to file
//By default this saved in cookies/example.site/cookies.json
req := app.Post("https://example.site/cookies")
req.Cookie().Save()
...
// Load saved cookies form cookies/example.site/cookies.json
reqWithCookie := app.Post("https://example.site/cookies")
reqWithCookie.Cookie().Load()
reqWithCookie.Do()
...

Is golang frontend or backend
Jul 08, 2025 am 01:44 AM
Golang is mainly used for back-end development, but it can also play an indirect role in the front-end field. Its design goals focus on high-performance, concurrent processing and system-level programming, and are suitable for building back-end applications such as API servers, microservices, distributed systems, database operations and CLI tools. Although Golang is not the mainstream language for web front-end, it can be compiled into JavaScript through GopherJS, run on WebAssembly through TinyGo, or generate HTML pages with a template engine to participate in front-end development. However, modern front-end development still needs to rely on JavaScript/TypeScript and its ecosystem. Therefore, Golang is more suitable for the technology stack selection with high-performance backend as the core.
How to install Go
Jul 09, 2025 am 02:37 AM
The key to installing Go is to select the correct version, configure environment variables, and verify the installation. 1. Go to the official website to download the installation package of the corresponding system. Windows uses .msi files, macOS uses .pkg files, Linux uses .tar.gz files and unzip them to /usr/local directory; 2. Configure environment variables, edit ~/.bashrc or ~/.zshrc in Linux/macOS to add PATH and GOPATH, and Windows set PATH to Go in the system properties; 3. Use the government command to verify the installation, and run the test program hello.go to confirm that the compilation and execution are normal. PATH settings and loops throughout the process
How to build a GraphQL API in golang
Jul 08, 2025 am 01:03 AM
To build a GraphQLAPI in Go, it is recommended to use the gqlgen library to improve development efficiency. 1. First select the appropriate library, such as gqlgen, which supports automatic code generation based on schema; 2. Then define GraphQLschema, describe the API structure and query portal, such as defining Post types and query methods; 3. Then initialize the project and generate basic code to implement business logic in resolver; 4. Finally, connect GraphQLhandler to HTTPserver and test the API through the built-in Playground. Notes include field naming specifications, error handling, performance optimization and security settings to ensure project maintenance
Resource Consumption (CPU/Memory) Benchmarks for Typical Golang vs Python Web Services
Jul 03, 2025 am 02:38 AM
Golang usually consumes less CPU and memory than Python when building web services. 1. Golang's goroutine model is efficient in scheduling, has strong concurrent request processing capabilities, and has lower CPU usage; 2. Go is compiled into native code, does not rely on virtual machines during runtime, and has smaller memory usage; 3. Python has greater CPU and memory overhead in concurrent scenarios due to GIL and interpretation execution mechanism; 4. Although Python has high development efficiency and rich ecosystem, it consumes a high resource, which is suitable for scenarios with low concurrency requirements.
Go sync.WaitGroup example
Jul 09, 2025 am 01:48 AM
sync.WaitGroup is used to wait for a group of goroutines to complete the task. Its core is to work together through three methods: Add, Done, and Wait. 1.Add(n) Set the number of goroutines to wait; 2.Done() is called at the end of each goroutine, and the count is reduced by one; 3.Wait() blocks the main coroutine until all tasks are completed. When using it, please note: Add should be called outside the goroutine, avoid duplicate Wait, and be sure to ensure that Don is called. It is recommended to use it with defer. It is common in concurrent crawling of web pages, batch data processing and other scenarios, and can effectively control the concurrency process.

Go embed package tutorial
Jul 09, 2025 am 02:46 AM
Using Go's embed package can easily embed static resources into binary, suitable for web services to package HTML, CSS, pictures and other files. 1. Declare the embedded resource to add //go:embed comment before the variable, such as embedding a single file hello.txt; 2. It can be embedded in the entire directory such as static/*, and realize multi-file packaging through embed.FS; 3. It is recommended to switch the disk loading mode through buildtag or environment variables to improve efficiency; 4. Pay attention to path accuracy, file size limitations and read-only characteristics of embedded resources. Rational use of embed can simplify deployment and optimize project structure.
