我将Base64输出到XCodes控制台,复制并粘贴它,它完美地工作.虽然我在数据库(MongoDB,纯文本文件等)中存储的Base64总是在另一端出现损坏.
工作版本(从XCode复制并粘贴):http://dontpanicrabbit.com/api/working.php 破碎版(来自MongoDB数据库):http://dontpanicrabbit.com/api/grabimage.php
如果你查看源代码,你会发现它们是相同的,但是在破碎版本中添加了空格.
我使用的Objective-C代码是:
MyImage.image = [info objectForKey:UIImagePickerControllerOriginalImage];
NSData *imageData = UIImageJPEGRepresentation(MyImage.image, 0);
[Base64 initialize];
NSString *encoded = [Base64 encode:imageData];
NSString *urlPOST = encoded;
//NSLog(@"%@",encoded);
NSString *varyingString1 = @"picture=";
NSString *varyingString2 = urlPOST;
NSString *post = [NSString stringWithFormat: @"%@%@", varyingString1, varyingString2];

,试图理解它如何将元组作为修饰符应用于响应.
据我所知,修饰符只是一个构建器对象,它引用当前上下文(self
)并将您希望构建的对象作为参数(只要您实现该modify
函数).
假设我们有以下代码:
use iron::modifiers::Header;
fn hello_world(_: &mut Request) -> IronResult<Response> {
let string = get_file_as_string("./public/index.html");

extensions: TypeMap::new()
