開發(fā)中單張圖片上傳這里不再贅述,下面我們看一下多圖上傳;
1.使用base64轉(zhuǎn)碼之后上傳
NSMutableDictionary *param = [NSMutableDictionary dictionary];
//需要上傳的圖片數(shù)組數(shù)組
NSMutableArray *imgsArr = [NSMutableArray array];
//self.imgs 圖片數(shù)據(jù)來源
for (UIImage *img in self.imgs) {
NSData *imageData = UIImagePNGRepresentation(image);
NSString *baseImg = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
[imgsArr addObject:baseImg];
}
param[@"imgs"] = imgsArr;
//url: 服務(wù)器地址 param: 參數(shù)信息
[LQHttpTool post:url parameters:param success:^(id responseObject) {
NSLog(@"上傳成功");
} faliure:^(NSError *error) {
NSLog(@"上傳失敗");
}];
2.使用formData表單上傳
NSMutableDictionary *param = [NSMutableDictionary dictionary];? ? ? ? ?
[LQHttpTool post:uploadBlog parameters:param constructingBodyWithBlock:^(idformData) {
//利用for循環(huán)上傳多張圖片
int i = 1;
for (UIImage * image in self.mImgs) {
//把圖片轉(zhuǎn)換為二進(jìn)制流
NSData *imageData = UIImagePNGRepresentation(image);
//按照表單格式把二進(jìn)制文件寫入formData表單
[formData appendPartWithFileData:imageData name:@"imgs" fileName:[NSString stringWithFormat:@"%d.png", i] mimeType:@"image/png"];
i++;
}
} success:^(id responseObject) {
NSLog(@"發(fā)布成功!!");
} faliure:^(NSError *error) {
NSLog(@"發(fā)布失敗!!");
}];
