下面是上传图像文件的片段.我只想使用NSURLSessionUploadTask,因为它提供了我想在我的应用中使用的后台上传功能.
我也不擅长服务器端代码.任何人都可以指导我做错了什么.
NSString* filePath = [[NSBundle mainBundle]
pathForResource:@"sample" ofType:@"jpg"];
uint64_t bytesTotalForThisFile = [[[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:NULL] fileSize];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:uploadPath];
[request setHTTPMethod:@"POST"];
[request setValue:[NSString stringWithFormat:@"%llu",bytesTotalForThisFile] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/octet-stream" forHTTPHeaderField:@"Content-Type"];
[request setTimeoutInterval:30];
NSString* filePath = [[NSBundle mainBundle]
pathForResource:@"sample" ofType:@"jpg"];
NSURLSessionUploadTask *taskUpload= [self.uploadSession uploadTaskWithRequest:request fromFile:[[NSURL alloc] initFileURLWithPath:filePath]];
<?PHP $objFile = & $_FILES["file"]; $strPath = basename( $objFile["name"] ); if( move_uploaded_file( $objFile["tmp_name"],$strPath ) ) { print "The file " . $strPath . " has been uploaded."; } else { print "There was an error uploading the file,please try again!"; }
从服务器端我得到$_FILES的空数组
我将举一个代码示例.检查控制台是否出现任何错误.

NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
// 2. if necessary set your Authorization HTTP (example api)
// [config setHTTPAdditionalHeaders:@{@"<setYourKey>":<value>}];
// 3. Finally,you create the NSURLSession using the above configuration.
NSURLSession *session = [NSURLSession sessionWithConfiguration:config];
// 4. Set your Request URL
NSURL *url = <yourURL>;
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
// 5. Set your HTTPMethod POST or PUT
[request setHTTPMethod:@"PUT"];
// 6. Encapsulate your file (supposse an image)
UIImage *image = [UIImage imageNamed:@"imageName"];
NSData *imageData = UIImageJPEGRepresentation(image,1.0);
// 7. You could try use uploadTaskWithRequest fromData
NSURLSessionUploadTask *taskUpload = [session uploadTaskWithRequest:request fromData:imageData completionHandler:^(NSData *data,NSURLResponse *response,NSError *error) {
NSHTTPURLResponse *httpResp = (NSHTTPURLResponse*) response;
if (!error && httpResp.statusCode == 200) {
// Uploaded
} else {
// alert for error saving / updating note
NSLog(@"ERROR: %@ AND HTTPREST ERROR : %ld",error,(long)httpResp.statusCode);
}
}];
