我正在编写一个 iPhone 应用程序，它将一些信息（一些文本和图像）发送到服务器脚本。

使用我的 php 脚本一切正常，但使用我客户的 jsp 脚本（将收到的信息发送到电子邮件地址的电子邮件）没有任何效果......（我知道因为我应该收到自动回复电子邮件，但这不会发生） .

我无法访问我的客户的脚本，因为他们是一个大客户并且“一些 bla bla 安全问题......”该脚本适用于在线 Web 表单，并且适用于 iOS 4.3 上的 ASIHTTPRequest（我正在迁移到iOS 5 ASIHTTPRequest 的 AFNetworking 原因不起作用）

任何帮助都非常感谢！

这是我的代码...请注意，我的代码总是到达 NSLog(@"Success") 但我没有收到任何自动回复电子邮件，所以它不起作用！

AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://my.client.server.com"]];


    NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
    [parameters setObject:[fieldName text] forKey:@"field01_nome"];
    [parameters setObject:[fieldSurname text] forKey:@"field02_cognome"];



    NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/Contents/mail/sendToForm.jsp" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
        [formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
    }];


    AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
        NSLog(@"Success");

    } failure:^(NSHTTPURLResponse *response, NSError *error) {
        NSLog(@"Fail");

    }];


    [operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
        NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);

    }];

    queue = [[[NSOperationQueue alloc] init] autorelease];
    [queue addOperation:operation];

非常感谢您！！

AFNetworking 和 multipart/form-data 也有问题。解决了。当 AFNetworking 为 multipart/form-data 生成 HTTP 正文时，它会将 \r\n sumbols 放在开头。您的 AFNetworking 机构和其他机构之间的区别 - 开头是 \r\n。尝试删除它。我已经修改了一些 AFHTTPClient.m 方法以将它们从正文的 begin 中删除：

static inline NSString * AFMultipartFormEncapsulationBoundary() {
    return [NSString stringWithFormat:@"%@--%@%@", @""/*kAFMultipartFormLineDelimiter*/, kAFMultipartFormBoundary, kAFMultipartFormLineDelimiter];

}

和：

- (void)appendPartWithHeaders:(NSDictionary *)headers body:(NSData *)body {
    [self appendString:AFMultipartFormEncapsulationBoundary()];

    for (NSString *field in [headers allKeys]) {
        [self appendString:[NSString stringWithFormat:@"%@: %@%@", field, [headers valueForKey:field], kAFMultipartFormLineDelimiter]];
    }

    [self appendString:kAFMultipartFormLineDelimiter];
    [self appendData:body];
    [self appendString:kAFMultipartFormLineDelimiter];

}

这个对我有用

ASIHTTPRequest 在 iOS 5.0 上运行良好；100 多个使用 ASIHTTPRequest 的应用程序在 iOS 5 上的问题为零。

也就是说，从长远来看，迁移到 AFNetworking 可能是有意义的。

这些“它可以在浏览器中工作但不能用于”类型的问题很难通过代码检查来解决 - 解决它们的最简单方法是安装像 charlesproxy 这样的工具。

安装后，开始捕获，然后在浏览器中执行请求，验证它是否成功，然后从 iOS 模拟器执行。然后将来自浏览器的请求与来自 AFNetworking 的请求进行比较，看看您能发现哪些差异。

如果您无法弄清楚，请编辑您的问题以包含两个捕获的请求，我相信有人能够发现它。
