服務器要求使用PUT方式上傳圖片, 采用網頁端的表單格式進行提交,由于之前很少使用PUT請求方式,只接觸過POST form-data方式和base64方式,調試了半天終于解決了,現在將方法拿出來,給大家參考,歡迎指正!

+ (void)putImageToServer{
    NSString * filePath = [[NSBundle mainBundle] pathForResource:@"image.jpg" ofType:nil];
    NSURL * fileURL = [NSURL fileURLWithPath:filePath];
    
//CBNetworkManager繼承自 AFHttpURLSessionManaager
    [NetworkManager put_uploadFileWithURLString:@"http://domain/goods/goods/uploadGoods Image?id=10002316&access_token=a351d9bde-0aqd-4f61-91s4-9af4d5d6664c" rename:@"apple.jpg" fromFile:fileURL orFromData:nil progressBlock:^(float progress) {
        CBNSLog(@"上傳文件進度%f", progress);
    } callBack:^(NSURLSessionTask *task, id response, NSError *error) {
        if (error) {
            CBNSLog(@"error = %@", error);
        }else {
            NSString * string = [[NSString alloc]initWithData:response encoding:NSUTF8StringEncoding];
            CBNSLog(@"success = %@", string);
        }
    }];   
}

// 上傳圖片方法,支持文件地址上傳和二進制數據上傳兩種方式
+ (void)put_uploadFileWithURLString:(NSString *)URLString
                             rename:(NSString *)rename
                           fromFile:(NSURL *)fileURL
                         orFromData:(NSData *)bodyData
                      progressBlock:(ProgressBlock)progressBlock
                           callBack:(RequestCallBack)callback

+ (void)put_uploadFileWithURLString:(NSString *)URLString
                             rename:(NSString *)rename
                           fromFile:(NSURL *)fileURL
                         orFromData:(NSData *)bodyData
                      progressBlock:(ProgressBlock)progressBlock
                           callBack:(RequestCallBack)callback{
    
    NSMutableURLRequest * request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"PUT" URLString:URLString parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
        [formData appendPartWithFileURL:fileURL name:@"file" fileName:rename mimeType:@"image/jpg" error:nil];
        
    } error:nil];
    
    void(^completionBlock)(id responseObject,NSError * error) = ^(id responseObject,NSError * error) {
        if (callback) {
            if (error) {
                callback(nil,nil,error);
            }
            else if (responseObject){
                callback(nil, responseObject,nil);
            }
        }
    };
    
// 方式一: 直接通過文件地址上傳
    if (fileURL) {
        // 使用表單的方式進行提交, uploadTaskWithStreamedRequest  另一個直接上傳FileURL 的方式,會報錯500
        NSURLSessionUploadTask * task =  [[CBNetworkManager sharedManager] uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) {
            if (progressBlock) {
                progressBlock(uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
            }
        } completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
            completionBlock(responseObject, error);
        }];
        
        [task resume];
    }
    
// 方式二: 將文件轉成二進制上傳,該方式文件后臺接收不到,不知道為啥,建議使用第一種
// 還有可能出現: `Domain=NSCocoaErrorDomain Code=3840 "JSON text did not start with array or object and option to allow fragments not set ` 錯誤,要指定響應接收類型
//        [CBNetworkManager sharedManager].requestSerializer = [AFHTTPRequestSerializer serializer];
//        [CBNetworkManager sharedManager].responseSerializer = [AFHTTPResponseSerializer serializer];


    if (bodyData) {
        [[CBNetworkManager sharedManager] uploadTaskWithRequest:request fromData:bodyData progress:^(NSProgress * _Nonnull uploadProgress) {
            if (progressBlock) {
                progressBlock(uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
            }
        } completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {
            completionBlock(responseObject, error);
        }];
    }
    
}

調用系統NSURLSession的方法如下:

/* Creates an upload task with the given request. The body of the request will be created from the file referenced by fileURL */

• (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request fromFile:(NSURL *)fileURL;

/* Creates an upload task with the given request. The body of the request is provided from the bodyData. */

• (NSURLSessionUploadTask *)uploadTaskWithRequest:(NSURLRequest *)request fromData:(NSData *)bodyData;
