项目里网络请求是必不可少的，框架使用的是AFNetworking三方库。在其基础上做了一层封装，你使用到的是JMRequestManager，这是一个单例。其主要三个方法GET、POST、upload

第一步：在JMHttpUrl.h定义接口的地址,如下：

#define kUrlLogin fPinUrl(@"api/account/login")//登录

第二步：就是调用接口啦

post请求示例：

    NSMutableDictionary *params = [JMCommonMethod baseRequestParams];
    [params setJsonValue:phone key:@"mobile"];
    [params setJsonValue:code key:@"code"];
    [params setJsonValue:password key:@"password"];
    
    [self showLoading];
    [[JMRequestManager sharedManager] POST: kUrlLogin parameters:params completion:^(JMBaseResponse *response) {
        [self dismissLoading];
        if(response.error){
            //失败,response.errorMsg就是失败提示语
            [JMProgressHelper toastInWindowWithMessage:response.errorMsg];
        }else{
            //成功,response.responseObject就是接口返回的字典
        }
    }];

upload请求示例：

1. 图片

    NSMutableDictionary *params = [JMCommonMethod baseRequestParams];
    [params setJsonValue:self.jubaoId key:@"byId"];
    NSString *text = self.inputTextView.text;
    [params setJsonValue:text key:@"content"];
    NSString *contact = self.inputContactTextField.text;
    [params setJsonValue:contact key:@"contact"];
    [self showLoading];
    [[JMRequestManager sharedManager] upload:kUrlJubao parameters:params formDataBlock:^NSDictionary<NSData *,JMDataName *> *(id<AFMultipartFormData> formData, NSMutableDictionary<NSData *,JMDataName *> *needFillDataDict) {
        for(int i=0;i<self.pictureData.count;i++){
            UIImage *image = self.pictureData[i];
            needFillDataDict[UIImageJPEGRepresentation(image, 0.3)] = [NSString stringWithFormat:@"image%d_image.jpg",(i+1)];
        }
        return needFillDataDict;
    } progress:nil completion:^(JMBaseResponse *response) {
        [self dismissLoading];
        if(response.error){
            [JMProgressHelper toastInWindowWithMessage:response.errorMsg];
        }else{
            [JMProgressHelper toastInWindowWithMessage:response.responseObject[@"desc"]];
            [self.navigationController popViewControllerAnimated:YES];
        }
    }];

注意
needFillDataDict[UIImageJPEGRepresentation(image, 0.3)] = [NSString stringWithFormat:@"image%d_image.jpg",(i+1)];
这个地方的image%d_image.jpg前面是接口的key，后面是这张图片的名称。

2. 视频

    NSMutableDictionary *params = [JMCommonMethod baseRequestParams];
    [params setJsonValue:[NSString stringWithFormat:@"%d",price.intValue] key:@"price"];
    [self showLoading];
    
    //视频压缩
    JMUploadVideoTool *videoTool = [[JMUploadVideoTool alloc] init];
    [videoTool compressVideoWithInputURL:self.videoUrl successBlock:^(NSURL *outUrl) {
        //压缩成功
        [[JMRequestManager sharedManager] upload:kUrlUpMai parameters:params formDataBlock:^NSDictionary<NSData *,JMDataName *> *(id<AFMultipartFormData> formData, NSMutableDictionary<NSData *,JMDataName *> *needFillDataDict) {
            needFillDataDict[UIImageJPEGRepresentation(self.selectImage, 0.3)] = @"img_image.jpg";
            NSData *videoData = [NSData dataWithContentsOfURL:outUrl];
            needFillDataDict[videoData] = @"video_video.mp4";
            return needFillDataDict;
        } progress:nil completion:^(JMBaseResponse *response) {
            [self dismissLoading];
            if(response.error){
                [JMProgressHelper toastInWindowWithMessage:response.errorMsg];
            }else{
                //移除本地视频
                [JMFileManagerHelper removeItemAtPath:[outUrl path]];
                [JMFileManagerHelper removeItemAtPath:[self.videoUrl path]];
                [UIAlertController jm_showAlertWithTitle:@"上麦成功" message:@"若有用户请求上麦时，您将会接到通知" appearanceProcess:^(JXTAlertController * _Nonnull alertMaker) {
                    alertMaker.addActionCancelTitle(@"确定");
                } actionsBlock:^(NSInteger buttonIndex, UIAlertAction * _Nonnull action, JXTAlertController * _Nonnull alertSelf) {
                    [self.navigationController popViewControllerAnimated:YES];
                }];
            }
        }];
    } failBlock:^(NSString *errorMsg) {
        //压缩失败
        [self dismissLoading];
        [JMProgressHelper toastInWindowWithMessage:errorMsg];
    }];

这里结合了视频压缩工具一起使用，且是图片+视频一起上传。
