在使用request.uploadFile实现 multipart/form-data 一个请求上传多个文件,抓包发现,会发起多次请求,每次上传一个文件。
async uploadFile(context: common.UIAbilityContext, func: string, params?: object, method?: http.RequestMethod, expectDataType?: http.HttpDataType): Promise<string> {
let netUrl = `${NetHelper.getBaseUrl(this.netWork, params)}${func}`;
let fileName: string = "";
let fileList = params["fileList"] as string [];
let files: request.File [] = [];
for(let filePath of fileList) { // 文件集合
fileName = filePath.substring(filePath.lastIndexOf("/")+1, filePath.length);
let parentDir: string | null = FileManager.getParentDir(filePath);
if (parentDir != FilePathGenerator.cacheDir) {
FileManager.copyFileSync(filePath, `${FilePathGenerator.cacheDir}/${fileName}`);
}
let suffixIndex = fileName.lastIndexOf(".");
files.push({ filename: fileName, name: fileName, uri: "internal://cache/" + fileName,
type: suffixIndex >= 0 ? fileName.substring(suffixIndex + 1, fileName.length) : "" });
}
let uploadConfig: request.UploadConfig = {
url: netUrl,
header: headers,
method: method?.valueOf(),
files: files,
data: datas,
};
return new Promise(async (resolve, reject) => {
try {
const uploadTask = await request.uploadFile(context, uploadConfig);
uploadTask.on('complete', (taskStates: Array<request.TaskState>) => {
logger.debug('taskStates');
logger.debug('taskStates[0].message:' + taskStates[0].message);
return resolve(taskStates[0].message);
});
uploadTask.on("progress",(receivedSize: number, totalSize: number)=> {
logger.debug("progress", `receivedSize: ${receivedSize} totalSize:${totalSize}`);
});
} catch (e) {
logger.error("uploadFile error:", e);
reject(new RYError("", RYErrorCode.UploadError, e));
}
})
}
可以使用ohos.net.http进行数据请求,参考链接:
