+* File download (breakpoint downloading supported).
+
+### Common Request
+
+```objective-c
+//JCAccessTokenRequest.h
+@interface JCAccessTokenRequest : JCBaseRequest
+
+@property (nonatomic, strong) NSString *appid;
+@property (nonatomic, strong) NSString *secret;
+@property (nonatomic, strong) NSString *code;
+
+@end
+
+//JCAccessTokenRequest.m
+@implementation JCAccessTokenRequest
+
+- (NSString *)baseUrl
+{
+    return @"base url";
+}
+
+- (NSString *)requestUrl
+{
+    return @"request url";
+}
+
+@end
+```
+
+```objective-c
+- (void)startGetRequest
+{
+    self.accessTokenRequest = [[JCAccessTokenRequest alloc] init];
+    self.accessTokenRequest.appid = @"your appid";
+    self.accessTokenRequest.secret = @"your secret";
+    self.accessTokenRequest.code = code;
+    [self.accessTokenRequest startRequestWithDecodeClass:[JCAccessTokenResp class] completion:^(id responseObject, NSError *error) {
+    	//do something
+    }];
+}
+```
+
+### Upload
+
+```objective-c
+//JCUploadTestRequest.h
+@interface JCUploadTestRequest : JCBaseRequest
+
+@end
+
+//JCUploadTestRequest.m
+@implementation JCUploadTestRequest
+
+- (JCRequestMethod)requestMethod
+{
+    return JCRequestMethodPOST;
+}
+
+- (NSString *)baseUrl
+{
+    return @"base url";
+}
+
+- (NSString *)requestUrl

+    return @"request url";
+}
+
+@end
+```
+
+```objective-c
+- (void)startUploadRequest
+{
+    self.uploadRequest = [[JCUploadTestRequest alloc] init];
+    [self.uploadRequest setUploadFilePath:@"file path"
+                               uploadName:@"file"];
+    [self.uploadRequest startRequestWithDecodeClass:[JCBaseResp class] completion:^(id responseObject, NSError *error) {
+    	//do something
+    }];
+}
+```
+
+### Download
+
+```objective-c
+- (void)startDownloadOperation
+{
+	JCDownloadItem *downloadItem = [[JCDownloadItem alloc] init];
+    downloadItem.downloadUrl = @"download url";
+    downloadItem.downloadFilePath = @"download file path";
+    JCDownloadOperation *operation = [[JCDownloadQueue sharedQueue] downloadOperation:downloadItem.downloadId
+                                                                              groupId:downloadItem.groupId];
+    if (!operation) {
+    	operation = [[JCDownloadOperation alloc] init];
+        operation.item = downloadItem;
+    }
+    [operation startWithProgressBlock:^(NSProgress *progress) {
+        //update progress
+    } completionBlock:^(NSURL *filePath, NSError *error) {
