1.安装OSS这些就不需要再说了，其次先让后台配置好一些参数，然后拿到后便可以直接使用了
目前用到的主要参数有以下三个：
ServerUrl
Endpoint
bucketName
2.直接在封装好的请求文件 CCNetworkRequstionMD5.m 里面，增加一个方法 （多种文件类型上传，传入你所需要的文件数组即可）
**** 主要代码：*****
+ (void)uploadFileArray:(NSArray *)fileArray success:(void (^)(id res))success{
NSMutableArray * array = [NSMutableArray array];
id<OSSCredentialProvider> credentialProvider = [[OSSAuthCredentialProvider alloc] initWithAuthServerUrl:OSS_STSTOKEN_URL];
OSSClientConfiguration *cfg = [[OSSClientConfiguration alloc] init];
cfg.maxRetryCount = 3;
cfg.timeoutIntervalForRequest = 15;
cfg.isHttpdnsEnable = NO;
cfg.crc64Verifiable = YES;
OSSClient *client = [[OSSClient alloc] initWithEndpoint:OSS_ENDPOINT credentialProvider:credentialProvider clientConfiguration:cfg];
[OSSManager sharedManager].defaultClient = client;
OSSPutObjectRequest * put = [OSSPutObjectRequest new];
[fileArray enumerateObjectsUsingBlock:^(CCHomeworkFileModel *fileModel, NSUInteger idx, BOOL * _Nonnull stop) {
put.bucketName = OSS_BUCKET_PRIVATE;//后台给的currentTimeStr
NSRange startRange = [fileModel.name rangeOfString:@"."];
NSRange range = NSMakeRange(startRange.location + startRange.length, fileModel.name.length - startRange.location - startRange.length);
NSString *type = [fileModel.name substringWithRange:range];
// objectKey看看后台需要什么样的格式上传，我们这边的格式是：日期/文件名（13位时间戳） 示例：20210128/1611807485567.jpg
put.objectKey = [NSString stringWithFormat:@"%@/%lld.%@",[CCNetworkRequstionMD5 getCurrentTime],[DateTranslate getNowTimeStamp],type];
put.uploadingData = fileModel.data; // 直接上传NSData字节
put.uploadProgress = ^(int64_t bytesSent, int64_t totalByteSent, int64_t totalBytesExpectedToSend) {
KLog(@"%lld, %lld, %lld", bytesSent, totalByteSent, totalBytesExpectedToSend);
};
OSSTask * putTask = [client putObject:put];
[putTask continueWithBlock:^id(OSSTask *task) {
if (!task.error) {
[array addObject:put.objectKey];//多张图片时这里面存放的图片名字的数组在把这些名字弄成json字符串 给服务器
if (fileArray.count > 1) {
if (idx == fileArray.count-1) {
success(array);
}
}else{
success(array);
}
} else {
NSLog(@"upload object failed, error: %@" , task.error);
}
return nil;
}];
[putTask waitUntilFinished];//这个时sdk给的用于多张图片上传时 加上它时只有第一个走了成功或者失败第二个才会走 。相当于等待串行。
}];
}
****以下不是主要代码，主要记录一下我这边使用的流程，可供参考*****
/// 获取文件上传成功后调用的
/// @param objs oss上传之后返回的ObjectName的数组，由path跟文件名组成，如“20210304/12345678.txt”
/// @param obj oss上传之后返回的ObjectName，由path跟文件名组成，如“20210304/12345678.txt”
/// @param isCompress 是否要进行压缩，某些特定场景需要传，比如添加课件 int
+ (void)getOSSFileUploadSuccessWithArray:(NSArray *)objs WithObj:(NSString *)obj WithIsCompress:(BOOL)isCompress success:(void (^)(id dataArray))success{
NSMutableDictionary *dic = [NSMutableDictionary dictionary];
if(objs.count > 0){
NSString *str = [objs componentsJoinedByString:@","];
[dic setObject:str forKey:@"objs"];
}else{
[dic setObject:obj forKey:@"obj"];
}
// [dic setObject:@"" forKey:@"isCompress"];
[CCNetworkRequstionMD5 NetRequestGETWithRequestURL:XQ_URLString(URL_File_OSS_Upload) WithParameter:dic isShowHud:NO WithReturnValeuBlock:^(id _Nonnull returnValue) {
CCCommonResponse *listModel = returnValue;
if (listModel.code == HttpCode_normal) {
NSArray*dataArray = [CCHomeworkFileModel mj_objectArrayWithKeyValuesArray:listModel.data];
success(dataArray);
}
} WithFailureBlock:^(id _Nonnull errorCode) {
}];
}
3.以下是在作业上传 CCHomeWorkDetailViewController.m 文件中的使用
- (void)updateFileRequestWithFilesArray:(NSArray *)filesArray{
NSMutableArray *nameArray = [NSMutableArray array];
[filesArray enumerateObjectsUsingBlock:^(CCHomeworkFileModel *obj, NSUInteger i, BOOL * _Nonnull stop) {
[nameArray addObject:obj.name];
}];
__weak typeof(self) weakSelf = self;
[CCNetworkRequstionMD5 uploadFileArray:filesArray success:^(id _Nonnull res) { // 使用OSS先提交 图片、文件
[CCNetworkRequstionMD5 getOSSFileUploadSuccessWithArray:res WithObj:@"" WithIsCompress:NO success:^(id _Nonnull dataArray) { // 获取上传后返回的数据
[dataArray enumerateObjectsUsingBlock:^(CCHomeworkFileModel *model, NSUInteger idx, BOOL * _Nonnull stop) {
[weakSelf.fileDataArray addObject:@{@"name":nameArray[idx],@"icon":model.icon,@"url":model.url}];
}];
[weakSelf getSaveNewNoteRequestWithFilesArray:weakSelf.fileDataArray]; // 提交作业请求
}];
}];
}
- (void)getSaveNewNoteRequestWithFilesArray:(NSArray *)filesArray{
NSMutableDictionary *param = [NSMutableDictionary dictionary];
if(self.textView.text.length > 0){
[param setObject:self.textView.text forKey:@"content"];
}
[param setObject:[NSString stringWithFormat:@"%d",self.model.id] forKey:@"schoolworkId"];
if(filesArray.count > 0){
[param setObject:filesArray forKey:@"files"];
}else{
if(self.textView.text.length == 0){
[HUDUtil ViewWithTitle:@"请先按要求完成作业"];
return;;
}
}
__weak typeof(self) weakSelf = self;
[CCNetworkRequstionMD5 NetRequstJsonWithMethod:@"POST" RequestURL:XQ_URLString(URL_Course_Work_Commit) WithParameter:param isShowHud:NO WithReturnValeuBlock:^(id _Nonnull returnValue) {
[HUDUtil hideHudAtWindow];
CCCommonResponse *listModel = returnValue;
if (listModel.code == HttpCode_normal) {
// 刷新页面
[[NSNotificationCenter defaultCenter]postNotificationName:@"ReloadHomeWorkListData" object:@{@"row":[NSString stringWithFormat:@"%zd",self.row],@"page":[NSString stringWithFormat:@"%d",self.page]}];// 刷新作业列表
[weakSelf.navigationController popViewControllerAnimated:YES];
}
[HUDUtil ViewWithTitle:listModel.msg];
} WithFailureBlock:^(id _Nonnull errorCode) {
[HUDUtil hideHudAtWindow];
}];
}
