Iphone 错误-“；损坏的JPEG数据：标记“之前有214个无关字节”；将映像发送到服务器后

我通过将图像转换为base64格式将图像发送到服务器。但问题是在发送图像字符串后，字符“+”将替换为一个空格“”。并显示了错误：

Corrupt JPEG data: 214 extraneous bytes before marker

如何解决这个问题？提前谢谢你的帮助

以下是转换为base64格式的图像转换代码：

-(NSString*)base64forData:(NSData*)theData {

const uint8_t* input = (const uint8_t*)[theData bytes];
NSInteger length = [theData length];

static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/=";

NSMutableData* data = [NSMutableData dataWithLength:((length + 2) / 3) * 4];
uint8_t* output = (uint8_t*)data.mutableBytes;

NSInteger i;
for (i=0; i < length; i += 3) {
    NSInteger value = 0;
    NSInteger j;
    for (j = i; j < (i + 3); j++) {
        value <<= 8;

        if (j < length) {
            value |= (0xFF & input[j]);
        }
    }

    NSInteger theIndex = (i / 3) * 4;
    output[theIndex + 0] =                    table[(value >> 18) & 0x3F];
    output[theIndex + 1] =                    table[(value >> 12) & 0x3F];
    output[theIndex + 2] = (i + 1) < length ? table[(value >> 6)  & 0x3F] : '=';
    output[theIndex + 3] = (i + 2) < length ? table[(value >> 0)  & 0x3F] : '=';
}

return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
}

这是服务器中显示的字符串：

为什么不将UIImage转换为NSData，将NSData转换为base64

NSData *imageData = UIImageJPEGRepresentation(image, 1.0);
NSString *base64string = [imageData base64EncodedString];

---

只需实现许多NSData类别中的一个，如以下类别：

您的

+

符号在post数据中不是URL编码的，即使您的内容类型说它们是URL编码的

您需要将它们替换为

%2B

，收件人才能正确获取它们
