代码（ANDROID）和我早上发布的一样

如果你不介意的话，你能帮我解决这个问题吗？

我认为使用AFN网络解决这个问题很容易

它将大大简化您的过程并节省大量时间。它被开发人员广泛使用

只需几行即可轻松发送带有参数的图像（后多部分请求）：

例如，检查此代码。（请确保参考上述链接并添加适当的头文件）

AFHTTPRequestOperationManager*manager=[AFHTTPRequestOperationManager]；
NSDictionary*参数=@{@“foo”：@“bar”}；
NSURL*filePath=[NSURL fileURLWithPath:@”file://path/to/image.png"];
[经理职务：@”http://example.com/resources.json“参数：参数constructingBodyWithBlock:^（id formData）{
[formData appendPartWithFileURL:filePath名称：@“image”错误：nil]；
}成功：^（AFHTTPRequestOperation*操作，id响应对象）{
NSLog（@“成功：%@”，响应对象）；
}失败：^（AFHTTPRequestOperation*操作，NSError*错误）{
NSLog（@“错误：%@”，错误）；
}];

您遇到的问题是，在组装表单数据之前，需要对base64数据进行URL编码（其中充满了解码为空格的

s，而不是

s）

可能的选择：

使用

CFURLCreateStringByAddingPercentEscapes

（确保要转义的字符中包含

）或

stringByAddingPercentEncodingWithAllowedCharacters:

转义数据（在汇编之前）

使用一些现有的库可以为您做到这一点
切换到更易于操作的其他格式，如JSON

这是我个人用于URL转义数据的类别：

NSString+urlencode.h：

#import <Foundation/Foundation.h>

@interface NSString (urlencode)

- (NSString *)escapedValueForURLParameter;

@end

#import "NSString+urlencode.h"

@implementation NSString (urlencode)

- (NSString *)escapedValueForURLParameter
{
    return (__bridge_transfer NSString *)
        CFURLCreateStringByAddingPercentEscapes(
                                                NULL,
                                                (__bridge CFStringRef) self,
                                                NULL,
                                                (CFStringRef) @"!*'();:@&=+$,/?%#[]",
                                                kCFStringEncodingUTF8
                                            );
