Ios 如何发送带有HTTP头的PUT请求和带有Objective-C的文件？

我是Objective-C的新手，请让我详细说明我在做什么

我正在尝试使用PUT请求将文件上载到OneDrive

PUT请求必须包含

Http头

内容长度7919

内容范围字节0-7918/7919

使用这些头文件将上载一个文件

PUT https://sn3302.up.1drv.com/up/fe6987415ace7X4e1eF866337
Content-Length: 7919
Content-Range: bytes 0-7918/7919

<bytes 0-7918 of the file>

---

感谢上帝，我终于找到了一条路。以下是已编辑的工作代码：

-(void)uploadFile:(NSString*)uploadUrl
{
    NSString *urlString = uploadUrl;

    NSData* file =  [NSData dataWithContentsOfFile: [@"/Users/username/Desktop/s.sql" stringByExpandingTildeInPath]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"PUT"];


    [request addValue:@"7919" forHTTPHeaderField: @"Content-Length"];
    [request addValue:@"bytes 0-7918/7919" forHTTPHeaderField: @"Content-Range"];


    NSMutableData *putData = [NSMutableData data];
    [putData appendData:[NSData dataWithData:file]];


    // Append
    [request setHTTPBody:putData];


    NSError *err;
    NSURLResponse *response;

    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];
    NSLog(resSrt);
}

我想你在这里谈论的是HTTP请求？是的@trojanfoe，正如你在屏幕截图中看到的那样，我注意到URL方案是

https://

。你应该让它在标题和文本中更加明显。我还注意到您在Postman和Objective-C代码中使用了不同的内容类型。为什么呢？

-(void)uploadFile:(NSString*)uploadUrl
{
    NSString *urlString = uploadUrl;

    NSData* file =  [NSData dataWithContentsOfFile: [@"/Users/username/Desktop/s.sql" stringByExpandingTildeInPath]];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"PUT"];


    [request addValue:@"7919" forHTTPHeaderField: @"Content-Length"];
    [request addValue:@"bytes 0-7918/7919" forHTTPHeaderField: @"Content-Range"];


    NSMutableData *putData = [NSMutableData data];
    [putData appendData:[NSData dataWithData:file]];


    // Append
    [request setHTTPBody:putData];


    NSError *err;
    NSURLResponse *response;

    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];

    NSString *resSrt = [[NSString alloc]initWithData:responseData encoding:NSASCIIStringEncoding];
    NSLog(resSrt);
}
