简介
HTTP是现代应用程序通过网络交换数据和媒体的的主要方式。httpclient是OpenHarmony 里一个高效执行的HTTP客户端,使用它可使您的内容加载更快,并节省您的流量。httpclient以人们耳熟能详的OKHTTP为基础,整合android-async-http,AutobahnAndroid,OkGo等库的功能特性,致力于在OpenHarmony 打造一款高效易用,功能全面的网络请求库。当前版本的httpclient依托系统提供的网络请求能力和上传下载能力,在此基础上进行拓展开发,已经实现的功能特性如下所示:
1.支持全局配置调试开关,超时时间,公共请求头和请求参数等,支持链式调用。
2.自定义任务调度器维护任务队列处理同步/异步请求。
3.支持tag取消请求。
4.支持设置自定义拦截器。
5.支持重定向。
6.支持客户端解压缩。
7.支持文件上传下载。
8.支持cookie管理。
9.支持对请求内容加解密。
10.支持自定义请求。
11.支持身份认证。
12.支持证书校验。
13.支持响应缓存。
14.支持请求配置responseData属性。
15.支持设置请求优先级。
16.支持证书锁定。

let hereAbilityContext: Context = getContext();
let hereCacheDir: string = hereAbilityContext.cacheDir;
let hereFilesDir: string = hereAbilityContext.filesDir;
const ctx = this
Logger.info(" cacheDir " + hereCacheDir)
let filePath = hereCacheDir + fileName;
Logger.info(" filePath " + filePath)
let fd = fs.openSync(filePath, fs.OpenMode.READ_WRITE | fs.OpenMode.CREATE)
fs.truncateSync(fd.fd)
fs.writeSync(fd.fd, "test httpclient")
fs.fsyncSync(fd.fd)
fs.closeSync(fd)
Logger.info(" writeSync ");
Logger.info( "create file success ")
// 由于文件上传目前仅支持"dataability"和"internal"两种协议类型,
// 但"internal"仅支持临时目录,示例 internal://cache/path/to/file.txt
// 所以需要将拿到的文件路径转化为internal格式的路径
filePath = filePath.replace(hereCacheDir, "internal://cache");
开始上传
javascript
import { HttpClient, Request, FileUpload,Logger } from '@ohos/httpclient';
let hereAbilityContext: Context = getContext();
let hereCacheDir: string = hereAbilityContext.cacheDir;
let hereFilesDir: string = hereAbilityContext.filesDir;
//生成文件上传对象并包装参数
let fileUploadBuilder = new FileUpload.Builder()
.addFile(filePath)
.addData("name2", "value2")
.build();
Log.showInfo('about to set : abilityContext - cacheDir = ' + hereCacheDir);
Log.showInfo('about to Set : abilityContext - filesDir = ' + hereFilesDir);
Log.showInfo("type of :" + typeof hereAbilityContext)
// 生成上传参数
let request = new Request.Builder()
.url(this.fileServer)
.body(fileUploadBuilder)
.setAbilityContext(hereAbilityContext)
.build();
this.client.newCall(request).execute().then((data) => {
// 上传进度回调监听
data.uploadTask.on('progress', (uploadedSize, totalSize) => {
Logger.info('progress--->uploadedSize: ' + uploadedSize
+ ' ,totalSize--->' + totalSize);
if (uploadedSize == totalSize){
Logger.info("upload success")
}
})
// 上传完毕回调监听
data.uploadTask.on('headerReceive', (headers) => {
Logger.info( 'progress--->uploadSize: ' + JSON.stringify(headers));
})
}).catch((error)=> {
this.status = "";
this.content = error.data;
Logger.error("onError -> Error : " + this.content);
});

let hereFilesDir: string = hereAbilityContext.filesDir;
try {
this.status = "";
let fPath = hereFilesDir + "/sampleEnqueue.jpg";
// request可以不设置下载路径fPath,如果不设置下载路径fPath,下载的文件默认缓存在cache文件夹
let request = new Request.Builder()
.download("https://imgkub.com/images/2022/03/09/pexels-francesco-ungaro-15250411.jpg", fPath)
.setAbilityContext(hereAbilityContext)
.build();
// 发起请求
this.client.newCall(request).enqueue((data) => {
// 设置下载完成监听
data.downloadTask.on('complete', () => {
Logger.info(" download complete");
this.content = "Download Task Completed";
});
// 设置下载进度监听
data.downloadTask.on("progress", ( receivedSize, totalSize)=>{
Logger.info(" downloadSize : "+receivedSize+" totalSize : "+totalSize);
this.content = ""+(receivedSize/totalSize)*100;
});

this.content = error.data;
Logger.error("onError -> Error : " + this.content);
});
} catch (err) {
Logger.error(" execution failed - errorMsg : "+err);
}
二进制文件分片上传示例
导入上传文件至应用cache目录 ,并使用chown命令修改用户权限
1. 查询应用cache沙箱路径对应的物理路径
2. 进入此物理路径,修改cache下的文件如uoload.rar的权限为同一个user_id
2.1 查询user_id 使用: ps -ef | grep cn.openharmony.httpclient 注:替换自己的包名即可,查询结果的第一列即为user_id
3.使用chown {user_id}:{user_id} uploar.rar 本例: chown 20010042:20010042 upload.rar
开始上传
javascript
import { HttpClient, Request,BinaryFileChunkUpload,Logger } from '@ohos/httpclient';
let hereAbilityContext: Context = getContext();
let hereCacheDir: string = hereAbilityContext.cacheDir;
// 待上传文件路径
let filePath: string = this.hereCacheDir + '/' + this.fileName
let fileUploadBuilder = new BinaryFileChunkUpload.Builder()
.addBinaryFile(hereAbilityContext, {
filePath: filePath,
fileName: this.fileName,
chunkSize: 1024 * 1024 * 4,
name: 'chunk'
})
.addData('filename', this.fileName)
.addUploadProgress(this.uploadCallback.bind(this))
.addUploadCallback(this.callStat.bind(this))
.build();
let request = new Request.Builder()
.url(this.baseUrl + '/upload')
.setAbilityContext(hereAbilityContext)
.body(fileUploadBuilder)
.build();
this.client.newCall(request).execute();
拦截器使用示例
javascript
import { Chain, Dns, HttpClient, Interceptor, Request, Response, TimeUnit, Utils,Logger } from '@ohos/httpclient';
// 通过addInterceptor添加拦截器
// addInterceptor允许调用多次,添加多个拦截器,拦截器的调用顺序根据添加顺序来决定
let request = new Request.Builder()
.url('https://postman-echo.com/post')
.post()
.body(RequestBody.create('test123'))
.setDefaultConfig(defaultConfigJSON)
.addInterceptor(new CustomInterceptor())
.build();
this.client.newCall(request).execute().then((result) => {
if (result) {
this.status = result.responseCode.toString();
}
if (result.result) {
this.content = result.result;
} else {
this.content = JSON.stringify(result);
}
Logger.info("onComplete -> Status : " + this.status);
Logger.info("onComplete -> Content : " + JSON.stringify(this.content));
}).catch((error) => {
this.status = error.code.toString();
this.content = error.data;
Logger.error("onError -> Error : " + this.content);
});
javascript
export class CustomInterceptor implements Interceptor {
intercept(chain: Chain): Promise<Response> {
return new Promise<Response>(function (resolve, reject) {
let request = chain.requestI();
Logger.info("request = " + request)
let response = chain.proceedI(request)

}).catch((err) => {
reject(err)
})
})
}
}

Multipart/form-data示例
创建RequestBody并使用创建的RequestBoy初始化MultiPart生成器
javascript
import {HttpClient,Request,RequestBody,MultiPart,TimeUnit,Mime,Logger} from '@ohos/httpclient';
let requestBody1 = RequestBody.create({Title: 'Multipart', Color: 'Brown'},new Mime.Builder().contentDisposition('form-data; name="myfile"').contentType('text/plain', 'charset', 'utf8').build().getMime())
let requestBody2 = RequestBody.create("HttpClient",new Mime.Builder().contentDisposition('form-data; name="http"').contentType('text/plain', 'charset', 'utf8').build().getMime())
let requestBody3 = RequestBody.create(data,new Mime.Builder().contentDisposition('form-data; name="file";filename="httpclient.txt"').contentType('text/plain', 'charset', 'utf8').build().getMime())
let boundary = "webKitFFormBoundarysioud821";
let multiPartObj = new MultiPart.Builder()
.type(httpclient.MultiPart.FORMDATA)
.addPart(requestBody1)
.addPart(requestBody2)
.addPart(requestBody3)
.build();
let body = multiPartObj.createRequestBody();
在请求/响应中使用multipart
javascript
let request = new Request.Builder()
.url(this.echoServer)
.post(body)
.addHeader("Content-Type", "multipart/form-data")
.params("LibName", "HttpClient-ohos")
.params("Request", "MultiData")
.build()

let client = new HttpClient.Builder().setConnectTimeout(10,TimeUnit.SECONDS)
.authenticator(new NetAuthenticator('jesse', 'password1'))
.build();
let request = new Request.Builder()
.get("https://publicobject.com/secrets/hellosecret.txt")
.addHeader("Content-Type", "application/json")
.build();

Logger.info('authenticator:' + result.responseCode.toString())
if (result) {
Logger.info('authenticator:' + result.responseCode.toString())
}
})
