今天遇到了图片Base64编码上传问题

在对Base64编码后的图片，进行JSON之后还要进行一次编码

代码如下

NSData *data = UIImageJPEGRepresentation(image, 0.5);

NSString *image64 = [database64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

NSLog(@"image64:%@",image64);

NSMutableDictionary *busiParam = [NSMutableDictionarydictionary];

[busiParam setObject:image64 forKey:@"images_content"];

NSString *busiJson = nil;

if ([NSJSONSerializationisValidJSONObject:busiParam]) {

NSError *error;

NSData *userData = [NSJSONSerializationdataWithJSONObject:busiParamoptions:kNilOptionserror:&error];

busiJson = [[NSStringalloc]initWithData:userDataencoding:NSUTF8StringEncoding];

}

//编码过程

static NSString *const kAFCharactersGeneralDelimitersToEncode =@":#[]@";// does not include "?" or "/" due to RFC 3986 - Section 3.4

static NSString *const kAFCharactersSubDelimitersToEncode =@"!$&'()*+,;=";

NSMutableCharacterSet * allowedCharacterSet = [[NSCharacterSetURLQueryAllowedCharacterSet]mutableCopy];

[allowedCharacterSet removeCharactersInString:[kAFCharactersGeneralDelimitersToEncodestringByAppendingString:kAFCharactersSubDelimitersToEncode]];

busiJson = [busiJson stringByAddingPercentEncodingWithAllowedCharacters:allowedCharacterSet];

NSString *postStr = [NSStringstringWithFormat:@"busiParam=%@",busiJson];

NSLog(@"postStr:%@",postStr);

NSData *postData = [postStrdataUsingEncoding:NSUTF8StringEncoding];
